Dynamic form values $_POST / edit shopping cart

Hi,

    I am creating a form that is dynamically generated, depending on items in the user's shopping cart. Is there anyway to do a dynamic
$_POST[$dynamicvalue]. Or is there another solution.

This is for when a user is editing his/her shopping cart before checkout. They are able to remove items and also to change quantities. The thing is that when they wish to remove an item, they click on a remove button next to the item. Now, naturally each item in the cart has an itemcartID. Each remove button is given the name REMOVE$itemcartID. Ex. If your itemcartID was 90 it would say REMOVE90. Now, i would like to check to see which one has been clicked using $_POST, the only thing is that each time the name will change. From REMOVE90 to REMOVE91 if it is another itemcartID. Got any solutions?

When you have an input button, the $_POST value is not the name of the input, yet, the x and y value.

eg. $_POST['image_x'] will give you a value
that way you can check each $_POST['REMOVE'.$variable.'_x']
and your code should work
