Filter: bricks/query_filters/custom_field_index_rows

Filters the index rows generated for a custom field in the Query Filters system. This allows providers (like ACF, Meta Box) or custom code to handle how complex field data is indexed for filtering.

Parameters

• $rows (array): Array of index rows. Each row is an associative array representing a filterable value.
• $object_id (int): The ID of the object (post, term, user) being indexed.
• $meta_key (string): The meta key of the custom field.
• $provider (string): The data provider (e.g., acf, metabox).
• $object_type (string): The type of object (post, term, user).

Example usage

add_filter( 'bricks/query_filters/custom_field_index_rows', function( $rows, $object_id, $meta_key, $provider, $object_type ) {
    // Example: Index a custom serialized field
    if ( $meta_key === 'my_serialized_field' ) {
        $value = get_post_meta( $object_id, $meta_key, true );
        // ... parse value ...
        $rows[] = [
            'filter_value' => 'parsed_value',
            'filter_value_display' => 'Display Value',
            // ... other required fields ...
        ];
    }

    return $rows;
}, 10, 5 );
