Why Create an Advanced Search Form for Custom Post Types in WordPress?
If you have many different content types, then a custom post type search form lets you help your visitors more easily find the most relevant content.
For example, we use custom post types here at WPBeginner to organize our deals and glossary sections. This keeps them separate from the rest of the content on our site.
If we were to add a custom post types search form to each of these pages, then the search results would only show posts from that category.
This kind of custom search helps your visitors view more pages and stay on your site longer, which gives off positive WordPress SEO signals like lower bounce rate and increased dwell time.
With that said, let’s show you how to create an advanced search form for custom post types in WordPress.
Create a New WordPress Search Algorithm with a WordPress Plugin
The easiest way to create an advanced search form for custom posts types is by using the SearchWP plugin. It’s the best search plugin for WordPress used by over 30,000 sites.
It’s easy to use and and gives you complete control over your WordPress search results.
First thing you need to do is install and activate the plugin. For more details, see our step by step guide on how to install a WordPress plugin.
Upon activation, you need to go to Settings » SearchWP and then click on the ‘License’ menu option.
Add SearchWP license key
Then, enter your license key in the ‘License’ box and click the ‘Activate’ button.
You can find this information in your account on the SearchWP website.
Once you’ve done that, you need to click on the ‘Engines’ menu option.
SearchWP engines settings
This brings you to a screen where you can set your search engine settings. Think of it like creating your own Google search algorithm for your website.
With SearchWP, you need to create a site-wide search engine before you can create a custom post types search engine, so we’ll do that first.
You can adjust the search engine settings by clicking on the ‘Posts’, ‘Pages’, ‘Library’, or other custom post type drop downs.
Each section has a ‘Weight Multiplier’ that will change how the search engines rank content.
If you want the search engine to value page titles higher than the content, then adjust the slider accordingly.
Adjust search engine attributes
Once you’re finished customizing your default search engine settings, make sure to click the ‘Save Engines’ button to create your first search engine.
Now that your initial search engine is set up, it’s time to create an advanced search form for your custom post types.
Add an Advanced Search Form Limited to a Single Custom Post Type
To create a custom search box, we’ll start by adding a separate search engine that only targets the custom post types you want.
First, navigate to Settings » SearchWP and then click the ‘Add New’ button.
Add new SearchWP search engine
This will automatically create a new separate search engine.
Next, click the ‘Sources & Settings’ button.
Click sources and settings
This will bring up a popup where you can select the sources for your custom search engine.
Simply uncheck the boxes of the sources you don’t want to include.
In this example, we’ll only leave the ‘Coupons’ box checked, since we want to create a search form that only lets users search through our coupon pages.
You also need to give your search engine a name. Take note of the name in the ‘Engine Name’ box, because you’ll need it at a later step.
Supplemental search engine settings
Then, click the ‘Done’ button.
Once you’ve done that, click the ‘Save Engines’ button to save your new custom post type search engine.
Now, you need to download the SearchWP shortcodes extension to easily add your new custom post search form to WordPress.
First, head over to the SearchWP Shortcodes Extension website and then click the ‘Download available with active license’ button.
Download SearchWP shortcodes extension
After that, you need to install and activate the extension the same way you installed the plugin above.
Now, you can create a new custom post search form page using shortcodes.
Simply navigate to Pages » Add New and then give your page a name.
After that, click the plus ‘Add Block’ icon to bring up the blocks menu.
Add block for shortcodes
Next, type ‘HTML’ into the search box.
Then, select the ‘Custom HTML’ block.
Select custom HTML shortcodes block
Once you’ve done that, you can add the following shortcodes and HTML to your page. If you need more help, then see our guide on how to add a shortcode in WordPress.

[searchwp_search_form engine=”coupon” var=”searchvar” button_text=”Find Results”]

<div class=”search-results-wrapper”>
[searchwp_search_results engine=”coupon” var=”searchvar” posts_per_page=4] <h2>[searchwp_search_result_link direct=”true”]</h2>
[searchwp_search_result_excerpt] [/searchwp_search_results] </div>

<div class=”no-search-results-found”>
[searchwp_search_results_none] No results found, please search again.
[/searchwp_search_results_none] </div>

<div class=”search-results-pagination”>
[searchwp_search_results_pagination direction=”prev” link_text=”Previous” var=”searchvar” engine=”my_test_engine”] [searchwp_search_results_pagination direction=”next” link_text=”Next” var=”searchvar” engine=”my_test_engine”] </div>

The code above will add your search engine, create a section to display the search results, show a no results message if necessary, and add pagination if the results go into multiple pages.
You need to change the engine name engine=”coupon” to your own engine name. The rest of the code can stay the same.
Publish SearchWP shortcodes page
Make sure you click ‘Publish’ or ‘Update’ to save your page and make it live.
Your custom post type search engine is now live on your website.
