submit comma separated value
Posted: Mon Mar 19, 2012 2:54 am
Hi guys I am new here and I am in search of some help!!
I am currently coding my way through an online shop and I am stuck on form submitting value to another page using the $_POST variable. So let me explain in code....
This page, named "product.php", holds a form that lists different sizes in a comma separated format to radio button list and is supposed to submit the product ID and the size (selected by user) that will be inserted to "cart.php" that is eventually the shopping cart page.
Now this little code here (cart.php), contains an array to hold every item added to cart by the user, that is working fine until I try to insert the selection of size selected by user of which gives me "Your Size: 84" ...(84 is the product ID) and leaves the array empty! but as soon as i remove the form for size submition the array works as it should!
Hope my explanation is clear enough...if not please ask for explanation again don't worry!!....ANY SUGGESTIONS GUYS?!?! I tried for about 2 hours solving the issue but got no result!!
