A Participants Database Add-On providing two different configurable multiple-field search capabilities.
Product Setup
The Combo Multisearch Plugin offers two main search control types: a single text input (like a search engine) or a set of selectors/checkboxes/text fields that provide a search term for each field. Both search types may be used, but in most cases, you’ll be using one or the other.
Setting up the Combination Search
Combo Search provides a single-input search that will look in multiple fields for a match to a single input. Use this search type in situations where a simple easy-to-use interface is desired to search the database.
To set up the Combo Search, you’ll need the names of all the fields you want searched with the user’s input. Type the names as a comma-separated list into the “Combination Search Fields” setting. To disable the combo search, leave the setting blank.
The “label” and “placeholder” settings give you two ways to prompt the user. The “label” is shown alongside the text input, and remains visible when the user types in their search. The “placeholder” is shown inside the text input, and disappears when the user begins to type in a search. A placeholder is good when you don’t need to explain much and want a clean, simple interface. The label is good for situations where you want to explain a little bit what the search is for. You can use either, neither, or both if you want.
Combo Search Modifiers
The “combo search modifiers” are a set of radio buttons to allow the user to set the type of search desired: “any,” “all,” or “phrase.” When enabled, these radio buttons will be shown next to the combo search input. There is a default search type that will be initially selected, and this is also the search mode that will be used if the combo search modifiers are not shown.
Autocomplete
“Autocomplete” is also known as “autosuggest” and provides the user with a list of suitable search terms. The list of suggested search terms is shown as a pop-up window when the user begins typing, and the list is pared down as the user types in more letters. The list of autosuggest words is drawn from the database, so it can reliably guide the user to search terms that will yield results. The fields that the autocomplete terms are drawn from is defined in the “Combo Search Autocomplete Fields” setting. It is a list of field names like the “combination search fields” setting. This means that the combo search can search on fields that don’t contribute to the autosuggest. This is helpful in cases where some of the fields searched contain blocks of text, which could add a lot of useless terms to the autosuggest list.
The terms that are available to the autosuggest are limited by the list shortcode filter, so data from records that are prevented from getting displayed won’t show up in the suggestion list.
Configuring the Multi Search
Multi Search provides a comprehensive interface for searching on multiple fields using a separate input for each field. This is best for situations where a precise, complex search is needed (such as a technical database) or in situations where you want to show the viewer what kind of information they can search by (for example, a services directory).
Starting with version 2.0, the multisearch fields are defined in a special interface under the “Multi Search Fields” tab in the plugin’s settings. In this new interface, each field in the multisearch can be customized in several different ways, changing how it looks, how the user may interact with it, and how it finds matches. Which options are available to a field depends on the type of field it is as defined in Participants Database.
If you already had Combo Multisearch set up and are updating from an older version, your fields will still be configured as before, only now you can fine-tune how each field works.
On this page, you configure which fields will appear in the multisearch and in what order. The display shows a list of all the fields configured for the Multi Search so you can edit the parameters of each one. You can add as many fields here as you want, you can also also delete and re-order them.
Note that fields that are included in the Combo Search configuration are not available for Multi Search; remove them from Combo Search to make them available in the “Add Field” selector.
Field Parameters
Each field in the list of fields has its own parameters where you can change how it is presented or how it works. There are several parameters, and which ones are available to each field depends on the field type. Here is a description of the parameters:
- Label – This defaults to the normal field title, but if you want to give it a different label in the search interface, you can do that here.
- Help Text – defaults to the field’s help text, but you can choose a different help text for the search interface.
- Attributes – allows the addition of HTML element attributes, such as the “required” attribute to selectively make fields required in the search interface.
- Input Type – depending on the original field type, there will be several different ways the field can be shown in the search interface.
- Include Label in Result Summary – when checked, the field’s label will be shown along with the searched-for value in the search result summary.
- Database Values in Selector – for any kind of selector input type, instead of showing the configured field options, the options shown in the control will be drawn from the database.
- Show “Any” Option – for selector input types, enabling this shows an option that will match any value in the database: this is essentially a “reset” for the selector, removing it from the search. Uncheck this if you want to force the user to make a selection.
- “Any” Option Label – when the “any” option is shown, this is how it will be labeled. You can leave it blank for a blank option.
- Multiselect “Or” Mode – (only for multiselect input types) if this is checked, the search result can match any of the values selected, instead of needing to match all of them when using “filter” mode. This setting makes no difference when not using filter mode because the values will be treated as an “or” in that case anyway.
Multi Search Field Input Type
Some field types will have several options available for the “Input Type” selected in the Multi Search Fields interface. A text field can be shown as a text input (of course) but also as a dropdown selector that shows a list of values taken from the database entries. Dropdown fields can be shown as a dropdown or as a multiselect, giving the user the ability to select several possible matches for that field.
Determining Which Multi Search Fields are Shown
Normally, a list shortcode configured to show the Combo Multisearch control will show all the fields you have configured in the Multi Search Fields interface. It is possible to determine on a per-shortcode basis which fields will be shown in the interface, as explained in the “Showing the Search Control” section. If you want to do this, you must configure all the fields you will show in all shortcodes, and then use the “search_fields” attribute in the shortcode to determine which of the configured fields to show in that particular display. In other words, you cannot add a field in the shortcode that has not been added to the Multi Search Fields configuration.
Filter Search Mode
The Combo Multisearch has two general modes of operation: Filter Mode on or off. With filter mode “on,” all chosen search values must match the record’s values for it to be included in a search result. If filter mode is “off,” a record will be included in the results if any of the provided search terms matches the record’s values.
When filter mode is on, any multi search fields that are configured with the “multiselect or” option will only require that one of the selected values in that field is a match. With “multiselect or” deselected, all the options selected for that field in the search must match.
Each search type, combo or multi, has a “Whole Word Match Only” switch so that text searches will only match a complete word in the search, not portions of a word. For multi-search controls, this only affects text inputs where the user types in the search term.
Searching on Date Fields
“Date” type fields can be presented as a single input or as a range with two inputs.
When using a single input, the search will attempt to include all records that correspond to the entered date.
When using the ranged inputs, the range will always include the date entered for the end of the range. For example, if the range is entered as “June 1, 2020” through “June 10, 2020” records that have a date of June 10, 2020 will be included in the result.
Partial Dates Supported
When using “date” fields in multisearch, it’s possible for users to enter partial dates, such as just the year, a month and a year, or just a month. For example “2010” will return all results with dates within that year. Entries like “March 2010” would return all dates within the month of March 2010. It’s als possible to enter a month: an entry of “May” will return all records with dates that are within the month of May in the current year. Partial dates can be used with ranged searches also: for example a search of “2000” through “2010” will return all dates between 2000 and 2010, inclusive.
When using a ranged input, if one of the inputs is left blank, it is assumed to be the current date. You can override this behavior by adding “required” to the attributes setting for the date field in the multisearch fields configuration.
Returning to the Search Results
Under the General settings tab is an option to enable restoring the previous search when returning to the search page. This is convenient for users who need to navigate away from the search page and wish to return to the same page of results. If this is unchecked, the search page will be reset every time it is loaded.
Showing the Combo Multi-Search Control
The Combo Multisearch Add-On provides its search capabilities through the use of a special template. There is a template for the list display and for the stand-alone search display. Once the plugin settings are defined, the template must be called in the shortcode like this:
[pdb_list template=multisearch ]
The plugin now also includes a table-less responsive template for the list multisearch shortcode:
[pdb_list template=multisearch-responsive ]
Or for the standalone search like this:
[pdb_search template=multisearch ]
If you are using the pdb_search shortcode, be sure to read Using the Search Shortcode as it can be tricky to configure.
It is possible to define the list of multisearch fields to search in the shortcode, drawn from the list of fields configured in the mutisearch fields setup. For example:
[pdb_list template=multisearch search_fields='company,city,state']
If you have both combo and multi searches configured, the combo search will only show if “combo_search” is included in the field list.
If you want a particular shortcode to show the combo search only, you can set that up like this:
[pdb_list template=multisearch search_fields='combo_search']
It is not possible to determine which fields are included in the combo search in the shortcode due to search optimization.
Setting Up a Remote Search
If you need to have the search control in a different location then where the results are displayed, you can do that with the [pdb_search] shortcode. You need to use the “target_page” attribute to tell the search shortcode where the results are to be displayed. The [pdb_list] shortcode is used to display the results. (Check this page for more on using the search shortcode…) For example, if your results are displayed on a page named “listings” then your search control shortcode will be like this: [pdb_search template=multisearch target_page=listings]. That shortcode can be placed anywhere. If you want to put it into a sidebar widget, you’ll need a plugin that will allow a shortcode in a widget. Then, on the “listings” page, put [pdb_list]. There is no need to set the template to multisearch unless you want another search control to appear at the top of the results.
Target Instance
In cases where the [pdb_list] shortcode is on a page with other Participants Database shortcodes, you may need to set the “target_instance” attribute to target the specific list shortcode where you want the results to appear. To find the target instance value, you must inspect the HTML. At the top of the list display, you will see a classname in the wrapper such as “pdb-instance-2” That means the list is instance 2, and you would need to put that value as the target instance in the search control shortcode, like this: [pdb_search template=multisearch target_page=listings target_instance=2].
F.A.Q.
Can I use both the Combo Search and Multi Search at the same time?
Yes, you can, but the set of fields selected for the Combo Search Fields should be different than the fields configured in Multi Search Fields. It will still work, but the results might not be as expected because the combo search will override the multi search if both are searching on the same field.
Is it possible for the user's last used search to be restored when they return to the search page?
Yes, there is a setting under the “General” tab in the Combo Multisearch settings called “Remember the Last Search” and if checked, it will store the search parameters for the last search on the user’s browser. This means that even if they leave the site and come back later, the last search they used will still be there. If “Clear” is clicked the stored search is erased.
I want to pre-load the search terms when linking to the search page. How do I do that?
Yes, it is possible to place the search terms in the URL, and they will pre-load into the search form.
For Multi Search, each field you want to preload a search term into needs to be named and given a value. For example, you want to take the user to the search page set up to find all the brewpubs in Seattle. Your link would look something like this:
https://xnau.com/search/?city=seattle&business_type=brewpub
The “city” and “business_type” fields would then be filled with the vales in the URL. Of course, the fields named must be configured to appear in the Multi Search inputs.
You can do the same for the Combo Search, but there is only one field, named “combo_search” so if you wanted to do the same kind of thing as our example above, you could use a URL like this:
https://xnau.com/search/?combo_search=seattle%20brewpub
You’ll notice the %20 in the search term: this is code for a space, this is needed because URL’s cannot contain spaces. Take a look at this reference to learn more about using query strings in URL’s.
I want to combine Combo Multisearch with Locations Map to show search result locations in the map. How can this be done?
Right now this doesn’t work using the “auto placement” of the locations map. You can get it all working together using a custom template I’ve created a template that will do the job here:
https://gist.github.com/xnau/39afbf647d78e85a7acdba4b0da30530
You’ll need to download that template, and place it where Participants Database can find it. This is explained here:
Using Participants Database Custom Templates
Once that’s done, change your shortcode to something like this:
[pdb_list template=multisearch-map]
I've got a very large database, are there any problems with this plugin with large databases?
Mostly, the size of the database is not going to matter at all, MySQL is pretty efficient with large databases.
There is one setting that will be affected, that’s the “Autocomplete” feature of the Combo search. For a very large database, you could get some memory errors with this feature. Two things you can try for that problem: limit the number of of fields that are going into the autocomplete (using the “Combo Search Autocomplete Fields” setting) which will cut down on the number of terms loaded into the autosuggest. Second, if your database is realy, really large, you may need to turn autocomplete off altogether.
If you are concerned with database performance issues, it’s a good idea to tune your server for better performance. You may want to ask your web hosting provider about that, it is a fairly technical subject and requires server configurations you may not have access to.

YEAH!!!!!!! I got it! Thank you so much, it works perfect now.

Hi, I bought the Combo Multisearch for a customer. Everything work fine on my Demo-Website. Now I transfer all to the customer page and the search doesn’t work anymore. Do you have any suggestions for me?
Can you provide a little more detail on what exactly is going wrong?
If you choose a branch and click on search (suchen) nothing happens. On my Testingsite it works fine. Do you have any idea what happens on the first site?
On my Testingserver it works: http://www.pd-sign.de/mitgliederliste/mitglieder/eintrag/
on customerserver it works not: http://www.mittelstand-bad-ra.de/mitglieder/eintrag/
Are you using the [pdb_search] shortcode? You don’t need it, just use the list shortcode like this:
[pdb_list template=multisearch]Hi Roland,
I use this shotcode on both sites:
[pdb_list template=multisearch list_limit=0 sort=false filter="approved=yes"]
[pdb_list template=flexbox search=false sort=false display_count=true list_limit=50 orderby="firmenname" order="asc,asc" filter="approved=yes"]
OK, you are using two shortcodes, one for the search and one to show the results. You can’t use the “list” shortcode that way, but you can use the “search” shortcode to show the search control in one location and the search results in another.
Try this:
There are also several changes to the shortcodes that remove unneeded elements.
Explanation of the “pdb_search” shortcode: The Search Shortcode
Hi Roland,
unfortunable that doesn’t work either. I absolutly have no idea what I can do.
– Petra
You can try using the multisearch responsive template:
[pdb_list template=multisearch-responsive display_count=true list_limit=50 orderby="firmenname" order="asc" filter="approved=yes"]This way, you don’t use the pdb_search shortcode at all, it’s all in one shortcode.
Hi Roland,
that works fine, BUT is it possible to use the flexbox Template for the list? I spent hours formatting the list like the customer want it. Now the list dont look like the first versionen anymore.
– Petra
Yes, but you will need to create a custom template that combines the layout for the list of results and the multisearch controls. If you look at the pdb-list-multisearch-responsive.php template that is included in the add-on, you can see how to create your own that uses the flexbox layout.
Using Participants Database Custom Templates
YEAH!!!!!!!
I got it! Thank you so much, it works perfect now.
– Petra
glad to hear it!
I purchased the combo-multisearch a few weeks ago and thought it was working just fine until my client keep telling that it wasn’t working. So I’d go in and change some settings, test it, and it would seem to work. I’d have the client look at it from their PC and it wouldn’t work still. So after spending hours trying to find a pattern to why it sometimes worked and other times it didn’t, I discovered a pattern. As long as I’m logged in to the WordPress admin area, it works. If I logout and then visit the page again (without closing the browser) it will still work. BUT as soon as I close the browser, reopen it to the page, it doesn’t work. Please fix this or tell me what I’m doing wrong here. Here’s the page with the issue: https://clicmeded.com/lic-programs/
Thanks, Steve of High Tech Services
Hi Steve,
These are the classic symptoms of page caching not allowing the page to update with new content. Try exempting the page from caching.
If that doesn’t fix it, try using the Alternative php Sessions setting in the plugin settings under the advanced tab.
Roland,
Excellent. As soon as I read your first suggestion about caching, I remembered that I use a plugin called WP Fastest Cache. I went there and found where I can exempt certain pages, so I exempted the main page listings that has the pdb_list code in it.
You have saved my bacon! My client will be thrilled this is fixed. Thanks so much for your help.
Note: I’m deleting the YouTube video I made. Perhaps you can remove that part I reference in my original comment above.

Hi Roland.
1. I have 7 websites of my own where I need to use the multi search extension with the participants database. Do I need to purchase one separate license for each?
2. How long will the license last?
Warm regards
Hi Awais,
The license for the add-on plugins is for a single site, but it does not expire: you will receive updates to the plugins for the life of the plugin. thanks!
Hello!
This add-on works perfectly, exept for the url pre-loading function. I set the url as you teach in this page but I can’t never make it work.
Does it works only under precise circumstances?
Thanks
I don’t know enough to say what the problem is. If you are asking about the Autocomplete, it only works with the “combo” search, there is not autocomplete for multi search fields.
Autocomplete uses javascript, so if there is a javascript issue on the page, it might not work. Do you have a link to the page so I can see the problem?
I’m referring to the “I want to pre-load the search terms when linking to the search page. How do I do that?” question in the FAQ in this page.
For example, if I put a url like the one you exposed (https://xnau.com/search/?city=seattle&business_type=brewpub) the list get no results
OK, now I get it. First, you need to use the correct field names. If you go to the Manage Database Fields page, find the fields you want to pre-load with values. Each field has a “name” which is what you will use in the URL. Now, for each of those fields you need to give it a value to preload. What can go in there will really depend on the kind of field it is. You must provide it with a value that is compatible with the type of field you want to pre-load with a value.
Be sure that you understand the syntax of putting values in a URL.
If the value has spaces or other special characters, you may need to encode that data…it’s called “URL encoding” and if you look it up, you’ll see how that works.
If you’re still having trouble, give me a specific example and I’ll see if I can help further.
Hi!
I just purchased the add-on. The shortcode works and the multi search is displayed, but I am having an issue with the way it looks on the website.
I am not sure if it’s an issue with its compatibility with the theme or if it’s something I have to manually change.
There is several line spaces between each of the search fields, a very large blank space at the top of the page, and the font doesn’t match at all with the rest of the site.
Is there any way to make it look better?
Thanks!
Hi Rachel,
I don’t have a really good answer for this, the plugin is designed to let the theme do the styling so that it will fit into the site without much tweaking, but of course there are themes that do things differently and so you get the kind of issues you’re seeing. There isn’t any set answer to your questions other than to inspect the HTML and see what the CSS is doing, then add rules that get you what you want.
In the case of fonts that are different, that can require a little detective work because the theme is probably using some specific selector (as opposed to a more general selector that would apply to nearly everything) to apply the font styles, and the output of the plugin doesn’t get those styles because the it’s got a different HTML structure.
So, it’s a bit complicated, but if you know the font style the theme is using (by inspecting some text that the theme is styling) then you can just write a CSS rule that will make all the plugin out put use that style.
The spacing is probably more easily dealt with, possibly the theme is applying some large margins to elements, so you’d write a CSS rule that overrides that in the case of the list elements.
If you need some basic help with working with the CSS, take a look at this article: Simple CSS Techniques for WordPress
I’m trying to have it list out my options as checkboxes instead of drop-downs, but I cant seem to figure out how to do it. Any suggestions?
The multisearch will use the same type of control that the field is set to use…so if you want a field to be shown as checkboxes in the search control, the easiest way to do that is to change the field to a checkbox-type field.
It is possible to use custom code to independently change the type of control that is used in the multisearch, not too difficult if you have some php skills.
Hi, purchased the plugin but unable to understand it.
My dropdown[SPF CATEGORY] is showing like this : https://1ce.org/1#Bydj8LTeN
I don’t want to select area i just want a dropdown. Can you please help ?
This is the control you will get for a “multi” type selector. It’s designed to give the user the ability to make multiple selections. If you’ve got some php skills, you can change what type of element is used to make the selection. For example:
You’ll need to alter that to fit your particular situation.
Thanks for your quick reply. Can you please tell me where to add this code?
This is like any WordPress filter, you can put it into your theme functions file.
Thank you brother :)
I’m using both the Combo Multisearch and Locations Map plugins and am trying to pre-load search terms (e.g., …/search/?category=photographers) into a search page (containing only the [pdb_list] and [pdb_listmap] shortcodes) but have had no success. The search page ignores the search and returns all listings. Any suggestions? Am I doing this wrong?
If you want the locations map to show the markers for the search results, you need to use a locations map that is embedded in the list. The [pdb_listmap] shortcode is for showing a stand-alone map an doesn’t respond to the search results.
Try using the “List Display Automatic Map Placement” for the list this is in the Locations Map settings under the dynamic map tab.
Hello!
I’m a newbie at wordpress and I found your plugin very useful. I just bought the combo-multisearch extension and it’s working great (I’m still learning how to use it), however I have a question, is it possible to use the pdb_total with a search result? I mean, all my records have a required numeric field, but I’d like to know if there’s a way to get the total of that field but only from those records which are the result from the search.
English isn’t my first language so I hope my question was clear enough for you to understand.
Thanks in advance!
You can’t use the “total” shortcode for this because it needs to be tied to the search result. The best way to do something like this is with a custom template, you will need to know php to do this, but it is not so simple. Do you know php?
Thanks for your quick answer. Sadly no, I don’t know php. I’ll try another approach to fulfill that need. Thanks anyway for your time and great support.
