How to include / exclude facet choices
You may occasionally need to exclude certain choices from a facet, or perhaps even include only certain choices. We’ll cover both approaches below.
Exclude certain choices
To exclude certain choices, add the following code to your (child) theme’s functions.php, and re-index afterward.
How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_filter( 'facetwp_index_row', function( $params, $class ) { if ( 'my_facet_name' == $params['facet_name'] ) { // Replace 'my_facet_name' with the name of your facet $excluded_terms = [ 'Featured', 'Reviews' ]; // Replace with the display value (not the slug) of your excluded terms if ( in_array( $params['facet_display_value'], $excluded_terms ) ) { $params['facet_value'] = ''; } } return $params; }, 10, 2 );
Setting $params['facet_value'] to an empty string prevents FacetWP from indexing the current value. You could also replace facet_display_value with facet_value to target the raw value.
Include only certain choices
To include certain choices, add the following code to your (child) theme’s functions.php, and re-index afterward.

Combine multiple rules
To apply rules to multiple facets, just use additional if statements.
