Product Support

Member Payments

Integrates PayPal payments into Participants Database with a full set of features for managing dues payments, pay-to-join and lots more.

Product Setup

Important Note

This plugin is complex and it involves a lot of configuration to get it doing what you need. It is very important to completely test the plugin’s functionality before you start taking payments. I suggest you use the PayPal Sandbox for your testing, it lets you make as many test purchases as you want so you can be certain it’s working as expected. I’ve included a special set of settings just for testing to help you avoid unpleasant surprises after you go live.

I do offer support for configuring the plugin, but I cannot guarantee a timely response. Don’t put yourself in the position of having to make an emergency support request. If you’ve tested the functionality before going live with it, you can be sure that things will go smoothly once you’ve started accepting payments.

How It Works

The plugin works by placing a PayPal payment button in a Participants Database form. When the user clicks on the PayPal payment button, the contents of the form is processed into Participants Database and the user is sent to PayPal to make the payment. When they complete their transaction, a record is made of the payment via PayPal Payment Data Transfer and/or Instant Payment Notification.

To keep a log of member payments, this plugin requires the PayPal account be configured to send Instant Payment Notifications and/or process a Payment Data Transfer.

Configuring the Member Payments Add-On is a bit complex, but these instructions will help you get it all working. These are the main parts, we’ll explain each one in turn.

  1. Set up the PayPal payment button
  2. Set up to receive PayPal payment data
  3. Set up your payment forms
  4. Set up payment logging

Configuring PayPal

Everything in this section requires that you be logged in to your PayPal account.

The first thing you will need to set up is the payment button. You may be familiar with this in PayPal, it is a little snippet of HTML that when displayed on a web page, is a clickable way to make a payment at PayPal.  If you are already using an instant payment button, you can use the same code in the Member Payments add-on.

Set Up Your PayPal Button

Log in to PayPal, and go to your Profile page. Click on My Selling Tools, and find PayPal Buttons near the top of the list of items on the right. Click on “update” to the right of “Manage my payment buttons.” That will take you to a list of default and custom buttons. If you already have a button set up, use that one. Otherwise, follow PayPal’s instructions for setting up a payment button.

Note that you cannot use a “hosted” button, it has to be a button that has all the the payment parameters in it.

Once you have your button code (you must copy it from the PayPal site) insert that code into the “PayPal Button HTML” setting in the Member Payments setup under the General tab. Now, all your Member Payments shortcodes will include that button in the form.

(Setting this up for PayPal Sandbox is exactly the same, with the important difference being you’ll be logged in to with your sandbox account.)

It’s also possible to use a different button code for each shortcode by including the button code in the “button_html” attribute of the signup, record or member payment shortcodes. More on that in the Product FAQ.

If you use “hosted” buttons (which are a bit more secure), you won’t be able to control the return page from the plugin side. The return page when using a hosted button is set up in the button configuration. If you have more than one payment portal, and want to give each one a different return page, you will need to define a separate hosted button for each one.

Logging Payments

There are two ways that PayPal sends transaction information to your website so that the user’s payments can be logged: Instant Payment Notifications (IPN) or Payment Data Transfer (PDT). You can use either or both, but it is recommended you use both so that you have a backup method in case one fails. Using both methods will not result in duplicates in the log, each transaction will only be logged once.

IPN and PDT both supply the same kind of information, but in two different ways:

  • IPN is asynchronous, meaning that is it sent in the background independently of the user’s actions, usually within a few seconds. That means that IPN doesn’t rely on the user going back to the site after authorizing the purchase. Their transaction will be logged anyway. In most cases, this method serves as a backup in case something happens and the user doesn’t make it back to the “thanks” page.
  • PDT requires the user to return to the “Return URL” so the payment data can be given to the website. The advantage here is that the information is available immediately. If you want your users to return to your site to be thanked and have their payment acknowledged, you must use this method.

More info on the difference between the methods from PayPal: IPN vs. PDT

Setting Up Instant Payment Notifications

  1. go to your PayPal profile/My selling tools
  2. find “Instant payment notifications” and click on “update”
  3. click on “Edit Settings”
  4. enter your IPN Notification URL: it is the home URL of your WordPress site
  5. select “Receive IPN messages”
  6. save, and you’re done.

Setting up Payment Data Transfer

  1. go to your PayPal profile/My selling tools
  2. find “Website preferences” click on “update”
  3. Auto Return: select “On”
  4. for the “Return URL,” put the URL for your “thanks” page (the one with the [[pdb_member_payment_thanks]] shortcode)
  5. find Payment Data Transfer, select “On”
  6. just below this, you’ll see the “Identity Token” select and copy this token
  7. go to the bottom of the page and click on “save”
  8. back on your WordPress site, in the Member Payments settings, general tab, paste in the token

With these configurations, logging of PayPal transactions can begin.

Payment Forms

There are three different ways to implement the Participants Database payment button. You can use any or all of them. You’ll need to decide which is right for your situation.

Once you have chosen the method or methods you want to use, you must either change your existing Participants Database forms shortcodes or place new shortcodes. You will need to place new shortcodes if this is a new installation or you want to use the “Member Payment” form.

The shortcodes provided by this plugin use all the same attributes of the regular Participants Database form shortcodes. The [pdb_signup_member_payment] shortcode shows a signup form with a PayPal payment button so that a new record is created when the form is submitted. The [pdb_member_payment] shortcode gives members an easy way to make a payment on their account.

If you are using custom templates, you must alter those templates to include the payment button. By inspecting the templates provided by this add-on and comparing to your custom template it’s easy to add the code needed to show the payment button.

Setting Up the “Thanks” Page

Each of the payment forms can be configured to take the user to a “thanks” page after the payment is made.

The way this works by default is a little different for each one. In all cases, after the user makes a PayPal payment, the user is returned to the “Return URL” as configured at PayPal. They will also be returned to this page if they cancel the transaction, and the plugin will show the “Cancel Return Message.”

For the Signup Payment form, when an offline payment is made, the thanks page will be the “Signup Thanks Page” as configured in the main Participants Database settings.

All of these behaviors can be modified in the shortcode. For the Signup Payment, the page the user is returned to after making an offline payment can be determined by the “action” attribute in the shortcode, for instance: [pdb_signup_member_payment action="offline-payment-thanks"] will send the user to a page named offline-payment-thanks after selecting an offline payment and submitting the form.

(Please note: for any thanks page that is designed to work with the Signup Payment form, you must use the [pdb_signup_member_payment_thanks] shortcode.)

For PayPal payments, the “return_url” and “cancel_return” attributes can be used to set what happens when making a PayPal payment…for example:

[pdb_signup_member_payment return_url="member-payment-thanks"]

This will return the user to the page named “member-payment-thanks” after making their PayPal payment, overriding the “Return URL” setting. When setting up a thanks page for the Member Payment form you must use the [pdb_member_payment_thanks] shortcode on that page.

All of the payment forms will work as their own thanks page: if the user goes back to the form page after making a payment or submitting the form, it will show the appropriate thanks message.

Configuring the Payment Log

The user’s payment is logged to a special field in Participants Database that is automatically set up by the Member Payments plugin. The new field will appear in an admin field group (if you have one, in the first field group if you don’t). After activating the plugin, go to the “Manage Database Fields” page in the admin, click on the tab for an admin field group (the default is “Administrative Info”), and look for a field named “Payment Log” That is your log field and you can change it’s configuration there, including changing it’s title or moving it to another group if you like.

Configuring the Log Fields

When a user makes a payment, PayPal sends a packet of data back to the site. There are lots of pieces of information in that packet, but only a few of them will need to be logged. The plugin pre-configures the log fields, and for most installs, that will be all you need. If you need, you can change which data fields you are logging in the log field configuration: Advanced Log Field Configuration

Configuring a Dues or Payment Schedule

For many situations, you will want members to make payments on a regular basis, such as for a dues payment. The plugin can tell you what each member’s payment status is, but in order to do that, you have to configure your payment schedule.

There are two kinds of payment schedule: fixed date and period. A fixed date schedule is for dues that are always due on a specific date or dates of the year. For instance a biennial schedule could be: January 1st and July 1st. The user’s payment becomes due on those dates. The period schedule is more like a subscription payment: the payment is for a set period of time, beginning the date the payment was made. The next payment will be due when that period is over.

See the “Settings” tab for details on configuring the payment schedule.

Member Payment Status

Each member has a payment status based on the payment schedule and when the last payment was made. Those statuses are:

  • paid (the member is current with payments)
  • payable (it is time to make a payment)
  • due (the payment due date is past)
  • past due (the member is late on their payment)

The “payable” and “past due” dates are configurable relative to the due date. For instance, you can set it up so that the payment becomes past due 7 days after the due date.

When the member’s payment status changes, an event for that change is triggered. When the Email Expansion Kit is installed, it is possible to set up an email that will be automatically sent on the status change. For instance, you can set up an email to go out when the member’s payment is due, and a different one that goes out when the member’s payment is past due.

Setting Up the Last Value Fields

In most cases, it’s the values in the last log entry that carry the most relevant values. You can create what are called “last value fields” that hold the last value of any of the log fields. One useful application of these fields is for showing information to the user: while the log itself is usually only visible to administrators, it may be useful for the regular user to know when the last payment was, for instance.

Last Value Fields are set up by creating a new field with the same name as the log field you want it to mirror. For instance, there is a log field named “payment_date” which holds the date of the payment. By creating a date field named “payment_date” you will set up a field that will always contain the date of the last payment in the log.

To set up a field that shows the last amount paid, you can create a field named “mc_gross” (this is the name of the payment amount field PayPal uses) and it will be filled in with the last amount paid, including manual payments. Once you have created the field, you can change the title of the field to anything you want.

Last Value Fields can use other field types, as well. For instance, with the “payment status” field there is a limited set of possible values (as defined in the IPN/PDT variables), which means it would work well as a dropdown field.

Note that the last value field must appear in the payment log for the value to be transferred to the last value field. This means that the field must be listed in the “options” of the Payment Log field.

If you are planning to offer options for your payments (such as different price options) you can track the user’s selection using a last value field. The instructions for configuring that are in this article: Setting up payment options in Member Payments.

Manual Log Entries

If the “Payment Log Edit Lock” setting is unchecked, it becomes possible to add a new entry to the edit log. When the new entry is added, it is placed in the log according to the payment date.

The manual log entry uses text fields to enter values unless a last value field has been defined for that log field. In that case, the last value field definition is used to define the input control used for the new log entry.

For instance, if you set up a dropdown field (as suggested above) for the “payment_status” log field, when adding a new log entry, the payment status field will be set using a dropdown control.

Value Tags

User feedback and emails use a templating system like the one in Participants Database that allows you to use “value tags” in your messaging. These value tags will include all the fields defined in Participants Database, all the data fields in the PayPal transaction, and several payment status fields if you are using the Payment Status module of the add-on. A value tag is simple the name of the field whose value you want to show in brackets like this [txn_id].

A list of useful tags is as follows.

  • [txn_id] – the transaction ID from the PayPal purchase
  • [txn_amount] – the transaction amount
  • [payment_status] – the current payment status of the account… like “paid,” “past due,” etc.
  • [last_payment_date] – the date of the last payment
  • [next_due_date] – the date the next payment will be due
  • [option_selection1] – if your payment button has options, the selected option will be in a field like this (the name may vary, look at your payment button code for the name you need to use)

Advanced Setup

Here are some instructions for getting deeper into the configuration of this plugin. Instructions in this section are optional, you don’t need to do anything here, they are additional capabilities you can access if you need.

Email Communications

This add-on works with the built-in email functionality of Participants Database: when the signup payment form is used, the person signing up gets the usual receipt email, and the administrator gets their notification (if configured to do so). The same is true of the “Profile Payment” form: as in Participants Database, there is no user email for updating their profile, but there is an administrator notification for that.

The built-in emails can all use the “value tags” from this add-on as described above.

Advanced Email Configuration

With the addition of the Email Expansion Kit, many more possibilities become available for email communications. Custom emails can be triggered on a number of events generated by this add-on:

  • Signup Payment Return
  • Member Payment Return
  • Profile Payment Return
  • Cancel Payment Return
  • PayPal IPN Recieved

Status Change Emails

When using the Payment Status module, events are generated when the member’s payment status changes. For instance, when a member’s uses payment becomes due. These status change events are triggered automatically in the background according to the date, and also when the payment log is updated with a new payment. There are four status change events that you can use:

  • Status Change to Paid
  • Status Change to Payable
  • Status Change to Payment Due
  • Status Change to Past Due

Advanced Payment Log Field Configuration

The payment log is pre-configured to include the most important fields of information. There is more information available, however, and this is how you can change which fields are logged.

Looking at the “Payment Log” field, in the “values” area, you’ll see the log columns defined as a comma-separated list of name::title definitions. For instance, the first one is payment_date::Date that means that the name of the data field is “payment_date” and the title of the field (or column) is “Date” You can change the title to anything you want at any time. Be careful about changing the name of the data field because that corresponds to a data filed in the packet the site receives from PayPal.

A full list of the data fields can be found here: IPN and PDT variables Much of that is pretty technical, and it may take a little research to understand what info you need to log. The default columns that are pre-set by the plugin will give you most of the important stuff, so you can just leave the default setting for the log fields in most cases.

Product Settings

PayPal Settings Tab

Payment Button Label

Optional text label for the payment button in the form.

PayPal Identity Token

This is an identifying code used by PayPal to authenticate a Payment Data Transfer communication with the web server. Not needed if you don’t use PDT.

PayPal Button HTML

Usually, this is obtained from PayPal from the defined payment buttons for your PayPal account. This HTML can be modified (if you know what you’re doing) to add selections and other variations, or to change the appearance.

Member Payment Settings Tab

These settings only pertain to the [pdb_member_payment] shortcode, you don’t need them if you are not using this payment method.

Payment Form Match Fields

These are the fields that are used to identify the user. This could be something like a “username/password” combination, or something as simple as a member ID or even an email address.

This form does not give access to sensitive information, but the field or fields must identify a single record only, so that the payment can be credited to a single record in the database.

Record Not Found Message

Message shown if the entered data does not match any record in the database.

Payment Thanks Message

Message shown on the screen after a payment is made. This is only seen if the user returns to the site after completing the payment at PayPal. Value tags are available in this template.

Cancel Return Message

If the user uses the “cancel return” button on the PayPal payment page and returns to the site without completing a payment, this message is shown on the screen.

Signup Payment Settings Tab

Approve on Payment

When checked, a new signup will have the “approved” field marked “yes” when payment is received.

Signup Payment Thanks Message

This message is displayed on the screen when the user returns after making a payment.

This the text on the submit button when using an offline payment method.

Offline Payment Method Help Message

This is shown next to the offline payment selection in the payment method selector.

Offline Payment Thanks Message

Shown after the user submits the signup form while using the offline payment method.

Payment Status Settings Tab

Enable Member Payment Status

Check this to keep track of your members current payment status.

Payment Due Mode

Theses correspond to two ways of structuring your member payments: either as a set schedule (Fixed Dates) with payments due on certain dates of the year, or as a period determined by the date of the last user payment (Fixed Period) like a membership subscription that is purchased for a set period of time.

This selection determines how the due dates are calculated, and so the next setting shown depends on this setting.

Fixed Dates: Renewal Dates

If the Payment Due Mode is “Fixed Dates” this setting is used to determine when those due dates are. This setting is a list of yearless dates, one date per line.

The default setting is

Jan 1
April 1
July 1
November 1

Which corresponds to a quarterly payment schedule beginning on January 1.

Fixed Period: Renewal Period

If the “Fixed Period” mode is used, this setting determines the period of time the membership payment is good for. Typical payment periods are available in a dropdown, more can be added using a code filter.

Multiple user-selectable payment periods, and payment for multiple periods (for instance if someone wanted to pay for more than one period) are not currently supported, but this is in the works.

Fixed Period: Late Payment Setting

When a payment is received before the due date, it is always credited to the due date, but if a payment is late, you can choose how the payment is applied in that case.

If “Payment goes to last due date” is selected, the late payment will always go to the last due date. For instance, if dues are collected every month, but a member is over a month late with their payment, they will be paying for the unpaid month, not the current month.

If “Payment goes to last payment date” is selected, the late payment counts from the date of the payment. For instance, as in the example above, if the member is over a month late, their payment will go to the current month, and the payment period will begin on the date of the payment.

Last Payment Date Field

This is the field used to store the date of the last payment. It must be a “Last Value Field” holding a date. This defaults to the “payment_date” field in the PayPal transaction data.

The text label used to show the payment status when the user is current with their payments.

Payment Due Status Label

The text label used to show the payment status when the member’s due date is passed, but is not overdue.

Payable Status Label

The text label used to show the payment status when the member’s payment can be made before the due date. This setting also has the number of days before the due date that a payment can be made.

This setting is important to determining which due date a payment can be credited to: if a payment falls within the payable period for a due date, it is assumed the payment is for that due date.

Past Due Status Label

The text label used to show the payment status when the member’s payment is overdue or past due. This setting also has the number of days after the due date that a payment becomes overdue.

Advanced Settings Tab

The settings under this tab are available to administrators only.

Payment Log Edit Lock

If this is checked, the payment logs cannot be edited. This also prevents manual log entries from being made.

Use PayPal Sandbox

PayPal Sandbox provides a way to test your payments setup. It does require some technical knowledge and requires a developer account with PayPal. Setting up the account is free, and PayPal does a good job of explaining how to do sandboxing.

You must use a sandbox account payment button and token to make sandboxed test payments.

More info on PayPal sandboxing here:

PayPal Sandbox Identity Token

This is the token to use while sandboxing, this is obtained from your sandbox account at PayPal.

PayPal Sandbox Button HTML

This is the button code to use while doing sandbox testing.

Testing Date

This is used for testing different scenarios for the member payment status. You can use this to simulate any date and what the member’s status will be on that date. This will also trigger any status change actions (such as an email if you have that configured in the Email Expansion add-on) so those can be tested as well.

This setting is only active if WP_DEBUG has been enabled. Keep it blank if you need to have WP_DEBUG on and want the member payment statuses to be calculated using the current date.

It is not recommended you run a live site with WP_DEBUG on, but if you must, you should leave this setting blank.


Is it possible to set the "return URL" in the shortcode?

Yes, both the Return URL and the Cancel Return Url can be set in the shortcode if you need a different payment flow for one of your forms.

What are the value tags or placeholders I can use in email templates?

The Member Payments plugin offers several value tags or placeholders that you can use in your email templates (when using the Email Expansion Kit) which include data returned from the payment processor and values that are generated as a result of the transaction. Here are some of the more useful ones:

  • [payment_status] shows the current payment status for the member (such as “paid” or “past due”)
  • [next_due_date] the date that the next payment will be due

PayPal return values

  • [mc_gross] when using PayPal, this is the amount of the payment that was just made. You can also use the [txn_amount] tag for the same thing.
  • [option_selection1] if you have a selector in your PayPal payment button, this is the value that was selected for that
Do you support other payment portals?

Not at this time, but it is in development. The Member Payments plugin currently supports only PayPal and offline payments.

What if a member wants to pay in person or with a check?

This is what “offline payments” are for. It gives you the ability to log a payment manually, and it will become part of the member’s record.

To add a payment log entry, open the member’s record for editing in the admin side. Find the “payment log” field, and you will see that it is possible to enter values for a new entry. Save the record to store the entry.

If you don’t see the fields you can type the new entry into, make sure the “Payment Log Edit Lock” setting is unchecked. Also, the backend user must have the necessary access level (usually editor or administrator).

Can I use a different PayPal button on another form?

Yes, there is the “button_html” shortcode attribute where you can place the HTML that will determine the PayPal button used. For instance:

[pdb_signup_member_payment button_html='<form action="" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="JAFG98A">
<tr><td><input type="hidden" name="on0" value="membership type">membership type</td></tr><tr><td><select name="os0">
<option value="newbie">newbie $10.00 USD</option>
<option value="regular">regular $25.00 USD</option>
<option value="gold star">gold star $350.00 USD</option>
</select> </td></tr>
<input type="hidden" name="currency_code" value="USD">
<input type="image" src="" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
<img alt="" border="0" src="" width="1" height="1">
</form>' ]

It’s important to use single quotes to enclose the HTML, and that the HTML uses double quotes only. If, for some reason, you need to include an apostrophe, you have to use the HTML entity equivalent: &#34;

Note: this code is not a valid button, you must create your own button code in PayPal.

Can a record be automatically un-approved when the payment period ends and they have not made a payment for the next one?

Yes, it requires that you set up an action that is triggered when the account becomes due. This is a gist that demonstrates how to do that.

This action is set to fire when the account becomes due. If the user pays before the due date, the record will not be unapproved because the event won’t fire.

This assumes that you have set up the “Payment Status Settings” in the Member Payments addon.

Is it possible to use "Field Group Tabs" with the payment forms?

Yes, but I had to release an update to make it possible. Because both add-ons affect how the submit buttons works, I needed to create a special template to make it work.

These templates are named “bootstrap-tabs” and you can use them by setting up your shortcodes like this:

[pdb_signup_member_payment tabs=true template=”bootstrap-tabs”]

[pdb_record_member_payment tabs=true template=”bootstrap-tabs”]

Of course, these can be customized, you can use these templates (located in the add-on as /templates/pdb-single-member-payment-bootstrap-tabs.php and pdb-record-member-payment-bootstrap-tabs.php) as a starting point. Be sure to pay extra attention to the submit button setup, it’s a bit complex.

How do I set up automatic notifications for a payment that is due?

You must install the Email Expansion Kit add-on to provide the additional email capabilities needed to automatically notify your users when a payment becomes due.

The process for setting this up is the same for all the payment status events Member Payments generates.

First, of course, configure your Payment Status settings according to your needs. This sets up the conditions under which a user knows whether they are paid, past due, etc. When the user’s status changes, an event is generated. This event can be linked to one or more email templates so that an email will be sent at that time. The Member Payments plugin uses a “cron” to automatically check for these status changes and trigger the event: the user does not have to be logged in for this to happen.

Once you have the Payment Status configured, create a new Email Template and assign the event to the “Send Action” for the template. To let a user know their payment is past due (for example) select “Member Payments: Status change to: Payment Past Due”. Be sure to fill in the recipient name and email (use value tags for that) and then fill in the body and subject of the email that you want sent when that event occurs. You may want to include a link to the page where the payment can be made.

How do I test payment status notification emails?

Once you have your payment status notifications set up (these are email templates that are configured to send when a user’s payment status changes), you may want to see what happens when a payment status change event is triggered. The best way to do this is to use a test account and start with a test payment so you know what the starting condition is. This is helpful because the trigger is a status change, so you will want to know what the initial status is.

Important: to test this you must have WP_DEBUG set. Take a look at this page if you’re unsure how to set that up. This is something you will only want to do temporarily, don’t run your site with WP_DEBUG on unless you’re actively testing. You should also turn debugging on in Participants Database so you can see in the debug log what happened.

So, let’s say that your payment is set up to be good for a month, and then the user needs to pay again. The way to test this is to go to the Member Payments settings under the Advanced tab and set the “test date” to more than a month from the date the test account made their payment. Now go to the test account’s admin edit page and save the record. The plugin will check the status and if it is changed, trigger the event and thus the email. Check the debugging log to see the outgoing email.

Testing the Cron

If you want to test the effect of the cron, you should first install a cron management plugin such as Crontrol. The Member Payment plugin uses a cron named pdbmps_cron_updates to check for payment status changes. Set the test date as explained above, then trigger that cron event. You will see the effect of the status change in the debugging log.

Be sure that you know the initial status of the record you are testing. If the record’s status is already at the tested status, then a change won’t happen and the event won’t be triggered. You may need to look at the record’s data directly (using phpMyAdmin) to know for sure what the initial status was.

Support Discussions for Member Payments

  • I want to send members a reminder email when Member Payments: Status Change to: Payable but I cannot get it to work on my test system.
    I have other PDb email templates working perfectly so I know there’s not a mail delivery problem and I’ve double checked the email template which looks ok to me.
    I’ve got the debugging log on and nothing is logged when a record changes to payable, and there is no log of an email being created.
    I’m not sure how the system works in terms of when the emails are generated but I am wondering if the problem might be because I’m testing it in a staging area?
    Please can you help me out here.

    • Probably, it’s just a configuration issue. First of all it’s important that the “payable” period and the “past due” period don’t overlap.

      It’s also important to understand that records that have no payment history are a special case. Since the plugin has no way of knowing what status such records should have, there is a setting for what the assumed status should be, but nothing will change for those records until a payment is made.

      Also, set the plugin debugging to “verbose” to show when records are getting their status checked. This happens when a record is updated, but also on a daily cron.

          determines how the payment due date is calculated.

          Renewal Period 1 Month

          the renewal period for the payment.

          Late Payment Setting
          Payment goes to last payment date
          determines what date a late payment is applied to

          “Paid” Status Label
          status label to use when the user has paid.

          “Payment Due” Status Label
          Payment Due
          status label to use after the payment is due.

          “Payable” Status
          days or less before due date is labeled:
          days before due and status label to use before the payment is due. IMPORTANT: the days before and the days after settings here must total less than the number of days between due dates.

          “Past Due” Status
          days or more after due date is labeled:
          days after due and status label to use after the payment is past due.

          Initial Payment Status Pending

          records with no payment history are assumed to have this payment status. If left blank, records with no payment history will not trigger payment status change events (such as to send an email) until after a payment is made.

        • I’ve just changed the ‘past due’ to 30 days. Will see what happens

        • if you are expecting records with no payment history to get a reminder when their payment is due, probably the initial payment status should be “paid” if you have it as “pending” nothing will happen until they make a payment. Also, for records with no payment history, the date of the payment is calculated from the date the record was created.

          Usually the best way to notify people who have never made a payment is to set up a special email and send it manually, using the admin list “with selected” event.

      • Hi Roland
        Thanks for the replies
        I am using the Accept Zero Amount Payments so all records are ‘current’ and change to ‘payable’ according to the settings. I’ve got a few lined up to change in the next few days and with the debugging now set to “verbose” I will keep an eye on what happens and get back to you.

      • Hi Roland
        What’s the best way for me to send you the debugging file?

        • Let’s start by telling me what your configuration is and what happened. For something like this it’s best to focus on a single record, so what was that record’s initial state?

        • Configuration
          Renewal period = 1 Month
          Payment goes to last payment date
          “Paid” Status Label = Current
          “Payment Due” Status Label = Payment Due
          “Payable” Status = 24 days or less before due date is labelled: Payable
          “Past Due” Status = 50 days or more after due date is labelled: Expired
          Initial Payment Status Label = Pending

          I have created 1 new record with payment type “PayPal” and will see what happens when it becomes “Payable” next week.
          Record’s initial state
          [12/19/19 2:57pm GMT]
          pdbmps\payment_status\payment_status_field::get_status_value Next Due Date: 19th Jan 2020
          Payable Date: 26th Dec 2019
          Past Due Date: 9th Mar 2020
          Current Date: 19th Dec 2019

          I just noticed that I have received a confirmation email from PDb email template Member Payments: IPN Received, but it’s not recorded in the debugging log.

          This line appears multiple times in the debugging log
          Undefined variable: value
          in /home/scentwo6/staging/1/wp-content/plugins/participants-database/classes/PDb_Tag_Template.php on line 302

        • OK, you can’t use “pending” as your initial status if you want an email sent out when the payment becomes payable. The initial status should be paid.

          Also, for testing purposes, you can simulate a future or past date when debugging is enabled by using the “Test Date” setting in the Member Payments settings under the advanced tab.

          I suggest you clear the debugging log before testing so you can get a clear picture of what happened.

          Don’t worry about the undefined variable notice, it isn’t a problem.

        • Hello Roland
          When a record is created it is “pending”. When it is paid it changes to “current”. This is the default setup which I have not changed. Is this OK?

        • If you want the email to go out when the account becomes payable, you must use an initial status of “current” (this is the same ad “paid”) Yes, this is not the default setting, you must change it so your payment notifications will go out.

  • Do you have a link to a way we could have the customer return to a thank you page that can also be printed as a receipt? Basically, a page populated with transaction details. I’m not sure of the best approach to this.

    • Yes, you can use the “Signup Thanks Message” to show all the relevant data. You can control the layout by using a custom template. The you’d have the user print the page from their browser. You will probably need to set up a CSS print sheet for that, you can do that in the plugin settings under the “Custom CSS” tab.

  • Problems when users backtrack from PayPal.

    I’ve got the system running live and using PDB Generate Member ID. Everything is working OK but I am amazed at how many people press the ‘back’ button when they get to PayPal and then start again. This creates two problems

    1 The [pdb_signup_member_payment_thanks] page does not display the ‘signup payment thanks’ message. It’s usually just blank although sometimes the ‘cancel return message’ is displayed.

    2 Two records are created. They are not duplicates because they have different member_id numbers. The first is pending, unapproved and second is all OK. I understand this is because the record is created whey the user clicks on the PayPal button

    I have to accept that people will backtrack from PayPal and I would be very grateful for any ideas as to how I might resolve the above problems.

    • There is little that can be done about this, the plugin can’t have any way of knowing this is what happened. You can filter for the aborted records and delete them. Do you know why they are doing this? Perhaps some instruction on the signup page will help minimize this.

      • OK thanks. I thought as much. I did put an instruction on the sign up page. Most get it right but I am surprised at how many don’t. I think it’s because they are mostly middle aged and older women who lack confidence with this sort of thing.

  • Reminder emails: problem if payment type = pay by check

    In a test scenario where 3 records were payment type = ‘PayPal’ and another 3 were = ‘pay by check’ all records changed from current to payable OK. Emails got sent to all the PayPal ones but only one of the Pay by Check ones.


    Is it possible to change a record from ‘Pending’ to ‘Current’ without entering a payment – i.e. free of charge? I am getting around this by entering a payment of 0.01 for now.

    • For the email issue, make sure you don’t have the “prevent duplicate emails” checked if you are testing the same record multiple times.

      It is possible to change the threshold for a manual payment getting credited as a payment with a filter. I’m considering adding it as a preference. The filter would be something like this:

      add_filter( 'pdbmps-is_valid_log_entry', function ( $valid, $data ) {
         return isset( $data['mc_gross'] ) && $data['mc_gross'] > -1;
      }, 10, 2 );
      • I do not have the ‘prevent duplicate emails’ checked. When I did, it prevented all but one of the payment type = PayPal ones from getting through but these were all going to the same email address. I have made sure that the payment type = pay by check ones all have different email addresses but only one is getting through.

        Regarding the free of charge ‘payment’, I for one would be very pleased if you add this as a preference.

        • Turn on plugin debugging, clear the debugging log, then test your email triggers. That will tell you if the email was sent. It’s a lot easier to debug problems with that information.

        • The next release adds a preference to allow a payment of $0 to credit a pending account with having received a payment. I expect to post it in the next few days.

  • Different response emails for member payment signups and renewals

    On return from PayPal the ‘signup payment thanks’ is different from ‘member payment thanks’ but I can’t find any way to make the response emails different.

    I have tried to set up a PDb email template and when I selected ‘Member payment return’ it just sent the signup response email as usual and the member payment thanks displayed a blank page.

    Is there a way to send an email message for pdb_record_member_payment which is different from the pdb_signup_member_payment ?

  • Is it possible for me to remove the ‘Info’ heading and the ‘save your changes’ section from the [pdb_record_member_payment] form so that it looks the same as the [pdb_signup_member_payment] form?


    Is it possible to search the participants list on member payment status? Whatever I try it won’t work, and when I do a csv export there’s no column for it.

    • It is possible to hide those things using CSS, or you can set up a custom template.

      There seems to be an issue with updating that value in the database. It is dynamically generated, but there is supposed to be a background process to keep the db value current. I will need to look into this, see what the issue is.

  • One other item once this is fixed.
    I noticed that there is only 1 year payment allowed as the max. Is there any way to add life time? As my site is based on longevity for our members. We are not requiring a constant income from members.

  • Updated the plugin and now it crashed my site. Assistance need.

    • Hi Donald, Sorry the update gave you trouble. I do need to know the details: were there any error messages? Did WordPress send you an email with the errors it encountered?

      Also, make sure your php version is minimum 5.6, that is required.

      • when updated to 4.2. website crashed. i am running php7.1

        • thanks, issuing a fix immediately

        • how do i update the plug-in to 4.2.1

          went to my orders page and clicked on the .zip link and it says that it is expired.

        • You should be able to update the plugin on the Plugins page, no need to download anything.

        • I will refresh your downloads if you can’t update from the plugins page and need to download the latest version.

        • The plugin page does not give me an option to update the membership payment plugin. I tried to click on the check for updates on the other Participants Database plugin and no luck. I can’t active the plugin, because it will crash the site.

        • I do see that I have 2 downloads available in my orders account page, but when I click on the download .zip file, an error page comes up stating that it is expired.

        • I’m sorry, my mistake, try it again, I made sure it’s available.

        • I’m sorry. I feel like such a pain. I see the date changed to Nov 30th, but the year was 2018.

        • No, I’m sorry, if I’d been paying closer attention, you wouldn’t have to ask…try it now.

  • Hello Again
    My clients wish to accept cheques for membership dues, and also have members that have already paid. So I enabled Offline Payments, but when I attempt to edit a record to input the payment date and next payment due date values for these records, the fields Offline Payment, Member Payment Status, Next Payment Due Date, and Last Payment Date are all locked as read only. I have Payment Log Edit Lock unchecked, however I don’t even see the payment log field in my Manage Database Fields.

    Am I missing something here or is this not how offline payments are supposed to be processed?

    • The values in those field are generated according to the contents of the payment log. If you manually add a payment to the log, it will update those fields.

      • How do I add a payment to the payment log?

        I found the ‘Configuring the Payment Log’ section of the instructions, but the Payment Log field doesn’t show up under Manage Database Fields under any of the tabs.

        • The Member Payments plugin installs the payment log field when it is activated, usually in the administrative group. It will be named “Payment Log.” If you don’t find it, you should be able to recreate it by deactivating and reactivating the plugin.

  • Hi,
    My PDB form plus Member Payments has been working fine for about a year!
    Recently, my client reported that the form stopped showing on the page as on the ‘Membership Support/Online Membership Signup’ page on the website submitted to you.
    The shortcode for the above page is: [pdb_signup_member_payment groups=”contact_info,membership_participation”]
    I did some testing:
    1) when I use the shortcode [pdb_member_payment], it works. See page /testing1/
    2) when I use the sortcode [pdb_signup groups="contact_info"] this works as well: see page /testing2/
    3) when I combine the 2 as so: [pdb_signup_member_payment groups=”contact_info], I get a WordPress message on the page “Updating Failed”. and I get a white screen if I try to access that page again (just on the page).
    I have done the following:
    — Upgraded to WordPress 5.2.2
    — Upgraded PHP version to 7.3
    — Deactivated/Activated the Member Payments plugin
    — Enabled debugging log file and the only message pertaining to PDB is:
    strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior
    in /home/gdetf/public_html/wp-content/plugins/participants-database/vendor/aux-plugin-update/Puc/v4p1/Plugin/UpdateChecker.php on line 454
    That’s all I know how to do! Any help would be much appreciated. I’m going to have the signup form go to a separate PayPal page upon Submit for now… Thank you!!

    • I don’t know what would cause the page editor to throw an error like that, the plugin is not involved in that operation at all. I guess make sure your shortcode syntax is correct, I notice your example is missing a quote.

      Probably unrelated to this, I posted some an update to Member Payments recently, make sure you are on the latest version.

      • Ahhh, In my example above #3, the shortcode did have the ending quotes, just not above…. However, now the member payments is working again. In my site,, page: /testing3/, I have this shortcode: [pdb_signup_member_payment groups=”contact_info”] and the two are working together again (signup and member payments). Like I mentioned before, the pages just “broke” — in both pages where I had the forms, the page cut off right after the title & before the shortcode. But both seem to be working fine now. Perhaps updating member payments helped. thanks.
