OpenCart Community

Hello there i am using Opencart 2.2 here. This method works perfectly but with one problem. I would like the user to click on a popup link and redirect to to the custom link at /index.php?coupon=XXXXX. But unfortunately if no product is in the user's cart the coupon is not applied at checkout. So the user has to have at least one product in his cart and then apply the link for the coupon to be applied. Is there a way for someone to first visit the coupon link, then add products at his cart and then at the checkout the coupon to be applied?
Thank you in advance.

Hi there! First, THANK YOU for taking the time to put this fix up here!

Second, I can't seem to get it to work in OpenCart 2.1.0.1 - I don't have a "framework.php" so I tried putting it in the index.php where described, but when I try the URL / coupon it does nothing.

Any thoughts?

Hi,
I tried adding the 2.2 code in framework.php of 2.3.0.2 and it doesn't work. Does anyone have a solution for 2.3.0.2?
Thanks,

I'm lurking the forum for a solution like this for 3.0.2.0. Any chance one of you know how to slip this trick into that version?

OC v3.0.2.0 . In catalog/controller/startup/startup.php file,

add above:
Then, in system/framework.php file,

This should resolved the issue.

Thanks a lot

Check both your OpenCart and PHP error logs.

In Opencart Log nothing added when this error occurs.
In PHP logs just 20x Code 301 GET /?coupon=XXXXX HTTP/1.0
No errors. Any idea how to solve this?

I've just tested the post code and it did work fine. However it has an XSS vulnerability so I would remove the code immediately.

It looks like you have a redirect somewhere when ?coupon=XXXXX is in the URL, maybe in your htaccess.
