Filter: bricks/query_filters/index_post/{source}

Filters the index rows generated for a post when the filter source is unknown or handled by a third-party provider. The {$source} portion of the hook name corresponds to the filter source (e.g., wcField or a custom source).

Parameters

• $rows (array): Array of index rows to be inserted into the database. Default is [].
• $post_id (int): The ID of the post being indexed.
• $elements (array): Array of filter elements targeting this post.

Each row must include filter_id, object_id, object_type, filter_value, filter_value_display, filter_value_id, and filter_value_parent.

Example usage

add_filter( 'bricks/query_filters/index_post/my_custom_source', function( $rows, $post_id, $elements ) {
    foreach ( $elements as $element ) {
        // Calculate filter value for this post
        $value = get_post_meta( $post_id, 'my_custom_field', true );

        if ( $value ) {
            $rows[] = [
                'filter_id'            => $element['filter_id'],
                'object_id'            => $post_id,
                'object_type'          => 'post',
                'filter_value'         => $value,
                'filter_value_display' => $value,
                'filter_value_id'      => 0,
                'filter_value_parent'  => 0,
            ];
        }
    }

    return $rows;
}, 10, 3 );
