I am writing a shopping cart using the PayPal API. Shopping cart
works. Just adding additional functionality.
From the shopping cart contents I am trying to make it so the user
may click on a picture of a trash can to delete the item. I wrote
the following line of code:
<INPUT TYPE="image"
SRC="http://www.theverseoftheday.info/store-images/trash_can.png";
WIDTH="20" HEIGHT="20" style="float: right;boarder: 0;" alt="Remove
Product From Shopping Cart" name="remove_product" value="1" />
But when I have do:
echo $remove_product;
I am not getting anything. Is there a correct way of passing a
variable through an image? The value in this above example is the
auto_increment value of the product. From this I could remove the
item from the shopping cart.
OR
Is there a better way to pass a variable through a graphic? I am
hoping for the shopping cart contents to be just 1 form where users
will have several options (change quantities, delete specific
items). I can't use a hidden field.
Thank you for your help.

Ron:
You don't need to pass a value. What you need is simply a trigger to
do something. As such, you can use lot's of things.
In this case, a button should work.

However, I would take all the styling (including dimensions) out of
it and place those in a css sheet.
Also, what's wrong with a hidden field?
