Are you looking for a way to improve the search functionality on your WordPress website? Do you want to provide your users with more accurate and relevant search results? One powerful tool you can use to achieve this is the ‘tax_query’ parameter in WordPress. By utilizing ‘tax_query’, you can filter search results based on specific taxonomies, allowing you to customize the search experience for your visitors. In this article, we will explore how to use ‘tax_query’ to filter search results and provide users with more targeted and personalized search results on your WordPress site.
function wpturbo_filter_search_results( $query ) {
if ( ! is_admin() && $query->is_main_query() && $query->is_search() ) {
$tax_query = array(
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => 'custom-category',
),
);
$query->set( 'tax_query', $tax_query );
}
}
add_action( 'pre_get_posts', 'wpturbo_filter_search_results' );
The snippet provided offers a solution to filter search results using the tax_query parameter in WordPress. This allows users to specify a specific taxonomy to filter search results by.
To begin, the code snippet contains a function called wpturbo_filter_search_results($query). This function takes the $query object as a parameter, which represents the main query being performed on the website.
Next, the code includes a series of conditionals to ensure that the function is only executed on the front end, is the main query, and is a search query. This helps avoid any interference with other queries or backend operations.
Within the main conditional block, we define the tax_query variable as an array. The tax_query parameter is used to specify the taxonomy and terms to filter the search results. In this example, we are filtering by the category taxonomy and the term custom-category. However, you can modify these values based on your specific requirements.
Finally, we use the $query->set('tax_query', $tax_query) method to modify the main query and include the tax_query parameter with our specified taxonomy and term(s). This ensures that the search results are filtered accordingly.
By using the add_action('pre_get_posts', 'wpturbo_filter_search_results') function, we hook the wpturbo_filter_search_results() function into the pre_get_posts action. This action fires before the main query is executed, allowing us to modify the query parameters before fetching the search results.
Overall, this code snippet provides a simple and effective way to filter search results in WordPress using the tax_query parameter.
