'The payment screen total value does not matches with the total order amount in cart in prestashop 1.7
I'm implementing external payment gateway in PrestaShop 1.7. But the payment screen amount does not update or matches the cart value in total. It keeps on showing the value which i passed in the template file (for privacy purpose, i have not written the values in code below).
I think I may have made a mistake in my main.php file. And Now i learnt my validation.php file also not working. I do not know why?
What should I do in this scenario? I'm new to PrestaShop, can't figure out?
Also what is the correct code for carrying out successful redirection, handle POST parameters and what will be the notify URL, cancel URL?
Please help me and update my code if i missed something.
edit: SORRY GUYS! I'm new to StackOverflow. So I included all files in console. Hopefully You can understand. I have mentioned file name at start.
This is the .tpl file
