facetwp_facet_html

Overview

This filter lets you modify a facet’s HTML output.

Parameters

$output | string | The facet HTML
$params | array | An associative array of facet settings (see below)

$params = [
    'facet' => [
        'name' => 'my_facet',
        'type' => 'checkboxes',
        'source' => 'tax/category',
        // any other facet-specific settings
    ],
    'values' => [], // available for checkbox & dropdown facets
    'selected_values' => [ 100, 101 ]
];

Usage

Add a “form-control” CSS class to all dropdown facets:

add_filter( 'facetwp_facet_html', function( $output, $params ) {
    if ( 'dropdown' == $params['facet']['type'] ) {
        $output = str_replace( 'facetwp-dropdown', 'facetwp-dropdown form-control', $output );
    }
    return $output;
}, 10, 2 );
