Modify relationship select field labels

Within the UI you can change the display field of a relationship field to a single other value using the “Display field” option: https://docs.pods.io/fields/relationship/

For most cases this is sufficient but there are cases in which you would want to have a more descriptive label for your options.
Since the labels are generated on both the initial render and later AJAX calls you will need to override this on both occasions.

Here is a code snippet you can use to modify these labels, please replace “FIELDNAME” with your field name.

add_filter( 'pods_field_pick_data_ajax_items', 'custom_pods_labels_in_pick_field_ajax', 1, 6 );
add_filter( 'pods_field_pick_data', 'custom_pods_labels_in_pick_field_data', 1, 6 );

function custom_pods_labels_in_pick_field_ajax($items, $name, $value, $options, $pod, $id) {
    if ( 'FIELDNAME' == $name ) {
        foreach ( $items as $key => &$data ) {
            if ( isset( $data['id'] ) ) {
                $data['text'] = custom_pods_select_field_label( $data['id'] );
                $data['name'] = $data['text'];
            }
        }
    }
    return $items;
}


function custom_pods_labels_in_pick_field_data($items, $name, $value, $options, $pod, $id) {
    // pods_meta_ prefix for Pods backend, pods_field_ prefix for front-facing Pods form
    if ( 'pods_meta_FIELDNAME' === $name || 'pods_field_FIELDNAME' === $name ) {
        if ( ! empty( $items ) && is_array( $items ) ) {
            foreach ( $items as $key => $item ) {
                if ( isset( $item['id'] ) ) {
                    $data['text'] = custom_pods_select_field_label( $data['id'] );
                    $data['name'] = $data['text'];
                } elseif ( is_numeric( $key ) && ! is_array( $item ) ) {
                    $items[ $key ] = custom_pods_select_field_label( $key );
                }
            }
        }
    }
    
    return $items;
}

function custom_pods_select_field_label( $id ) {
    // You can return anything you want here.
}
