gform_notification_validation

This filter was removed in Gravity Forms v2.5 and is no longer supported.
From Gravity Forms 2.5, notification settings and their validation callbacks are now defined via the gform_notification_settings_fields filter.

Description

The gform_notification_validation filter can be used to validate custom notification settings added using the gform_notification_ui_settings and gform_pre_notification_save filters and override the default validation result.

Usage

The following would apply to all forms.

1
add_filter( 'gform_notification_validation', 'your_function_name', 10, 3 );

To limit the scope of your function to a specific form, append the form id to the end of the hook name. (format: gform_notification_validation_FORMID)

1
add_filter( 'gform_notification_validation_5', 'your_function_name', 10, 3 );

Parameters

  • $is_valid boolean

    The result of the default notification validation which checks if the emails for the to, bcc, and replyTo settings are valid.

  • $notification array

    An array of properties which make up the notification object to be saved. See Notifications Object for default properties.

  • $form Form Object

    The current form object to which the notification being saved belongs.
