Problem with file shirts.php
Why do I keep getting the following error on this page?
Notice: Undefined variable: products in C:\xampp\htdocs\shirts\shirts.php on line 18
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\shirts\shirts.php on line 18
Hey Gabriela, the first error means you haven't defined your variable. In PHP terms, this means you have to initalize it before it can be used. I'm not sure what your code looks like, but you can simply add in $products = " "; to set the variable to nothing. This may solve your problem for the invalid argument, too. I'm not sure what your foreach() loop looks like, either.
Same as the comment above. Either the variable products doesn't exist or is empty. Posting your code would help us figure out what exactly is the problem
