New payment gateway addon incredible error - php

Question

i'm making some tests to develop a custom payment gateway addon in cscart
The development has been very simple and intuitive, but there is a thing i am going crazy
for 1 week. After the transaction as been completed the user is redirected to index.php?dispatch=checkout.complete&order_id=20036 but the green popup notification dosn't appear as on the other payments....
The code looks like normal.. i look on all other payments script and all is regular
the final function in /core/fn.cart.php fn_order_placement_routines valorize correctly the $_SESSION var with the notification data fn_set_notification('N',.....
this is the code
if (!defined('AREA') ) { die('Access denied'); }
if (defined('PAYMENT_NOTIFICATION')) {
if ($mode == 'notify' && !empty($_REQUEST['order_id'])) {
if (fn_check_payment_script('gateway.php', $_REQUEST['order_id'], $processor_data)) {
$order_id = $_REQUEST['order_id'];
$order_info = fn_get_order_info($order_id);
$pp_response = array(
'reason_text' => '',
'order_status' => 'F'
);
if (empty($processor_data)) {
$processor_data = fn_get_processor_data($order_info['payment_id']);
}
$returnvalue = $_POST['PROCESSING_RESULT'];
if ($returnvalue && strstr($returnvalue,"ACK")) {
$pp_response['order_status'] = "E";
$pp_response['reason_text'] .= "Status: OK";
}else {
$pp_response['order_status'] = "N";
$pp_response["reason_text"] = fn_get_lang_var('text_transaction_cancelled');
}
if (isSet($_REQUEST['IDENTIFICATION_UNIQUEID'])) {
$pp_response['transaction_id'] = $_REQUEST['IDENTIFICATION_UNIQUEID'];
}
[b] fn_finish_payment($_REQUEST['order_id'], $pp_response, false);
fn_order_placement_routines($_REQUEST['order_id'], true);[/b]
}
}
} else {
if ($mode == 'place_order') {
//call the gateway, assign response url etc
// $current_location."/".$index_script."?dispatch=payment_notification.notify&payment=gateway.php&order_id=".$order_id;
}
}
the fn_order_place_routine should be show by default the green or red popup based on the status of the order.... nothing.. dosn't appear
thanks in advance

Answer 1

As I can see you are using custom order status for sucessfull transaction:
$pp_response['order_status'] = "E";
So, to display notification the 'inventory' option for this status should be set as 'Decreased'. In this case the E status will be included in the result of the fn_get_order_paid_statuses() function and the following code in the fn_order_placement_routines function will work:
if (in_array($status, fn_get_order_paid_statuses())) {
if ($action == 'repay') {
fn_set_notification('N', __('congratulations'), __('text_order_repayed_successfully'));
} else {
fn_set_notification('N', __('order_placed'), __('text_order_placed_successfully'));
}
}
Best regards.
