Custom Fields Hook

I have created hook to pass custom fields to card pointe. Further implementation will be needed. It works with no problem for now.

// Add this to your template file or custom code snippet plugin

add_filter('add_custom_field', 'custom_authorize_fields', 10, 6);
function custom_authorize_fields( $request, $feed, $submission_data, $form, $entry, $max_retries ) {
	if ($form['id'] == 33){
	$firstName     = rgpost( 'input_3_3', true );
	$lastName      = rgpost( 'input_3_6', true );
	$customerID    = rgpost( 'input_5' );
	$invoiceNumber = rgpost( 'input_12' );
	$clinicName    = rgpost( 'input_6' );
	$cardHolderName = rgpost( 'input_1_5' );
	$email = rgpost('input_4');
	$telephone = rgpost('input_16');

	
     $request ['email']   = $email;
	 $request['phone'] = $telephone;
     $request['userfields'] = array(
	'firstName'     => $firstName,
	'lastName'      => $lastName,
	'customerID'    => $customerID,
	'invoiceNumber' => $invoiceNumber,
	'company'    => $clinicName,
	'cardHolderName' => $cardHolderName,
);
   
	 }
	

	return $request;
}

// This is inserted in the cardpointe plugin in wp-content/plugins/integration-for-cardconnect-and-gravity-forms/class-gravityforms-cardconnect.php
// Is on line 720. in function authorize()
// $request = apply_filters( 'add_custom_field', $request, $feed, $submission_data, $form, $entry, $max_retries);
