Changing the From Email for GravityForms Notifications

There are rare instances that you need to be able to programmatically make sure the from email is not set to a certain email.  Using the following filter will allow you to modify the From portion of the header before it sends. This code Snippet uses the fix_email snippet that can be found by clicking here.

add_filter( 'gform_pre_send_email', 'before_email_sent', 10, 4 );
function before_email_sent( $email, $message_format, $notification, $entry ) {
    // If GF logging is enabled, then it will record the a before an after of the email in the log.
    GFCommon::log_debug( __METHOD__ . '(): EMAIL BEFORE => ' . print_r( $email, true ) );
    $newEmail = 'correct@email.com';
    if ($newEmail != '') {
        // Check the Fix Email Function code snippet for what this does. It pretty much just changes the email within <> of the string.
        $updated_from = fix_email($email['headers']['From'], $newEmail); 
        $email['headers']['From'] = $updated_from; 
    }
    GFCommon::log_debug( __METHOD__ . '(): EMAIL AFTER => ' . print_r( $email, true ) );
    return $email;
}
