How to show custom message after redirecting back user from module

[mohitbumb]

Hi,

I've created prestashop module for Payment Gateway and it works fine but if/for any reason order is not completed properly then after my external api response I redirect back user to step 1 with help of this code :

    Tools::redirect('index.php?controller=order&step=1');

But now I want that flow + also wanted to show user a proper message which comes from my api lets say I've message in variable $message but how can I show it to user after him/her back to step 1 

Is there anything like flash messages or something which can solve my issue

Hello,

Option 1: Cookies
Option 2: Variables session ($_SESSION)
Option 3: Insert in the redirection Tools::redirect('index.php?controller=order&step=1&message=My message here');

 

Regards!
