Pods 2.7.x – fix for predefined list “pick” fields

<?php

add_filter( 'facetwp_index_row', function( $params, $class ) {
    if ( 'pais' == $params['facet_name'] ) {
        require_once PODS_DIR . 'classes/fields/pick.php';
        $pick = new PodsField_Pick();
        $countries = $pick->data_countries();
        $label = $params['facet_display_value'];
        if ( isset( $countries[ $label ] ) ) {
            $params['facet_display_value'] = $countries[ $label ];
        }
    }
    return $params;
}, 10, 2 );
