PHP Build a Simple PHP Application Integrating with PayPal Building the Shirt Details Page

RESOLVED: Product ID not changing when clicking different shirts

When I am clicking different shirts the product id on the shirt.php page URL is not changing. It is always:


I thought that I must have written the code incorrectly, so I substituted the code I had written in shirts.php and shirt.php with the working code supplied by Randy. I got the same result with Randy's code.

I tried another web browser (Safari on Mac OSX) and it works fine.

How can I prevent this happening on my local MAMP Pro server?

I am assuming it is caused by a browser cache?

Many Thanks



Great course Randy. I am learning more by doing your course than I have from reading numerous PHP books over the last few years.

I'm a bit of a PHP "Shelf Development" expert :-)

RESOLVED: Did a search for clear browsing data using help menu on Crome browser and cleared:

Cached images and files

Seems to be working fine now.
