How to Search By Category in WordPress (2 Ways)

Published on 8. May, 2021

Do you want to add category specific search in WordPress?

Adding a search by category feature to WordPress lets your visitors quickly find what they’re looking for. You can add options to search specific blog categories, product categories, and more.

In this tutorial, we’ll show you how you can add a search by category feature to your WordPress site.

Why Add Search By Category to WordPress?

A search by category feature allows your visitors to search specific website categories.

If you have a lot of content, then categories can help organize your content and make it easier for your visitors to find what they’re looking for.

You can add a category search feature to your archive pages to help your visitors quickly find what they’re looking for.

Category search can also be added to your online store, so visitors can quickly find the exact products they want.

Overall, this offers your visitors a better onsite experience and can help your WordPress website give off positive SEO signals like increased dwell time and lower bounce rate.

The best way to add a category search feature is by using a WordPress plugin.

We’re going to share two different WordPress search plugins that can help you customize WordPress search. Simply use the quick links below to choose the type of WordPress category search you want to add.

Method 1: Using SearchWP to Add Category Select Search Form to WordPress

SearchWP is the best search plugin for WordPress. It’s very easy to use and lets you add a category selection feature, giving your users control over their search results.

First, you need to install and activate the SearchWP plugin. For more details, see our step by step guide on how to install a WordPress plugin.

Upon activation, navigate to Settings » SearchWP. This brings up the main search settings menu.

You can adjust the search engine settings by clicking on ‘Posts’, ‘Pages’, or ‘Library’ drop downs.

Changing the ‘Weight Multiplier’ sliders customizes how the search engine values content. If you want the search engine to value page content higher than the title, then adjust the slider accordingly.

SearchWP save search engine

Once you’re done, make sure you click the ‘Save Engines’ button to generate your first search engine.

Next, we’re going to customize the search form to add a category selection option, so your visitors can decide which category they want to search.

To do this, you’ll need to add code to your WordPress files. If you haven’t done this before, then check out our guide on how to copy and paste code in WordPress.

You’ll need to copy and paste the following code and add it to your functions.php file, in a site-specific plugin, or by using a code snippets plugin.

function my_searchwp_get_search_form_with_categories_dropdown( $form ) {
	ob_start(); ?>
		<form role="search" method="get" class="search-form" action="<?php echo home_url( '/' ); ?>">
				<span class="screen-reader-text">Search For</span>
				<input type="search" class="search-field" placeholder="Search..." value="<?php echo esc_attr( get_search_query() ); ?>" name="s" title="Search for:" />
				// for more information see https://codex.wordpress.org/Function_Reference/wp_dropdown_categories
				$swp_cat_dropdown_args = array(
						'show_option_all'  => __( 'Any Category' ),
						'name'             => 'swp_category_limiter',
				wp_dropdown_categories( $swp_cat_dropdown_args );
			<input type="submit" class="search-submit" value="Search" />
	<?php return ob_get_clean();

add_filter( 'get_search_form', 'my_searchwp_get_search_form_with_categories_dropdown' );

This code modifies the search form on your WordPress blog, and gives users a drop down box to select their preferred category.

After the code is added you can view any of your search forms, and you’ll see that a category search drop down has been added.

Now, under your search form title, copy the shortcode and paste it into a text file.
