Hi, I am new to programming in php and I am having a couple issues. I followed a tutorial on building a php shopping cart and I am trying to add an option to choose a size in the shopping cart. On the product page, it carries over the item ID but not the size option I am trying to implement. Below is my code for the product page:
and this is my shopping cart code:
Basically, I just need the size variable(my value) from the drop down menu on the products page to be able to carry over to the shopping cart.I am also having trouble adding this item to the array. I apologize if this is too much code, this is the first time I have posted something on here. Thanks
