Description
Enables users to change the email validation for the TO address on notification pages. Useful to allow merge tags or shortcodes to be added to the TO field.
Usage
1 | add_filter( 'gform_is_valid_notification_to', 'validate_to_email', 10, 4 ); |
Parameters
- $is_valid boolean
The value being filtered. True if the to email is valid. False otherwise. Gravity Forms performs the validation before executing this hook, so $is_valid will contain the result of that validation. To override Gravity Form’s validation, simply set the value of this variable to true or false and return it.
-
$to_type string
The type of “Send To” that is configured. The possible values are “email”, “field” and “routing”.

The email address configured. Only applies when type ($to_type) is set to “email”
-
$to_field string
The ID of the field selected to be used as the “Send To”. Only applies when type ($to_type) is set to “field”
