Pods CMS: How to add custom column to Adnvanced Content Type

To customize which fields are shown in Pods UI, you can filter the default UI options through this filter / function combination. Overriding the $ui array with the options you wish to customize, this can be pretty quick and easy.

function pods_ui_test ( $ui ) {
    // Test on UI Column
    $ui[ 'fields' ][ 'manage' ] = array(
        'city' => 'City',
        'region' => 'Region'
    );

    return $ui;
}

add_filter( 'pods_admin_ui_cities', 'pods_ui_test' );
