Filter the feed settings fields (typically before they are rendered on the Feed Settings edit view).


The base filter which would run for all add-on feeds would be used like so:

add_filter( 'gform_addon_feed_settings_fields', 'your_function_name', 10, 2 );

You can target a specific add-on with the following variation of this hook:

add_filter( 'gform_{ADDON_SLUG}_feed_settings_fields', 'your_function_name', 10, 2 );

See the Gravity Forms Add-On Slugs article for a list of possible slugs.



1. Add a Custom Setting to the First Section of All Feeds

add_filter( 'gform_addon_feed_settings_fields', 'add_custom_addon_setting', 10, 2 );
function add_custom_addon_setting( $feed_settings_fields, $addon ) {

$feed_settings_fields[0]['fields'][] = array(
'name'  => 'my_custom_setting',
'label' => 'My Custom Setting',
'type'  => 'text'

return $feed_settings_fields;

2. Add a Custom Setting After the “Send Email” Setting for All User Registration Feeds

This example shows how the add_field_after() helper can be used to add a new setting after a specific existing setting.

add_filter( 'gform_gravityformsuserregistration_feed_settings_fields', function( $feed_settings_fields, $addon ) {

$feed_settings_fields = $addon->add_field_after( 'sendEmail', array(
'name'  => 'my_custom_setting',
'label' => 'My Custom Setting',
'type'  => 'text'
), $feed_settings_fields );

return $feed_settings_fields;
}, 10, 2 );

3. Remove ‘Password’ Setting for User Registration Feeds for a Specific Form

This example shows how the remove_field() helper can be used to remove one of the settings.

add_filter( 'gform_gravityformsuserregistration_feed_settings_fields', function( $feed_settings_fields, $addon ) {

$form = $addon->get_current_form();
if( $form['id'] == 1 ) {
$feed_settings_fields = $addon->remove_field( 'password', $feed_settings_fields );

return $feed_settings_fields;
}, 10, 2 );

4. Add a Custom Setting to Certain Payment Add-Ons

This example shows how an add-on which uses the Add-On Framework, in this example it’s the User Registration Add-On, can add a custom setting to add-ons which extend GFPaymentAddOn and support subscription cancellations.

public function init() {
add_filter( 'gform_addon_feed_settings_fields', array( $this, 'add_subscription_feed_setting' ), 10, 2 );
public function add_subscription_feed_setting( $feed_settings_fields, $addon ) {
$addon_supports_subscriptions = $addon instanceof GFPaymentAddOn && $addon->method_is_overridden( 'cancel', 'GFPaymentAddOn' );

if ( $addon_supports_subscriptions ) {

$ur_settings = array(
'title'      => esc_html__( 'User Registration Options', 'gravityformsuserregistration' ),
'tooltip'    => sprintf( '<h6>%s</h6> %s', esc_html__( 'User Registration Options', 'gravityformsuserregistration' ), esc_html__( 'The selected form also has a User Registration feed. These options allow you to specify how you would like the PayPal and User Registration Add-ons to work together.', 'gravityformuserregistration' ) ),
'fields'     => array(),
'dependency' => array( 'field' => 'transactionType', 'values' => array( 'subscription' ) ),

$ur_settings['fields'][] = array(
'name'       => 'cancellationActionUser',
'label'      => esc_html__( 'Update User on Cancel', 'gravityformsuserregistration' ),
'type'       => 'checkbox_and_select',
'checkbox'   => array(
'label' => esc_html__( 'Update user when subscription is cancelled.', 'gravityformsuserregistration' )
'select'     => array(
'choices' => $this->get_update_user_actions_choices()

$feed_settings_fields = array_merge( $feed_settings_fields, array( $ur_settings ) );

return $feed_settings_fields;
