How to store shopping cart items in session PHP?
Use the key in the cart session variable:
In the loop use the ID as product reference: $pid = $item ['pid']; echo "<button type='submit' name='buy' value='$pid'>Buy</button> "; ... and increment the value by one if it is already in the cart ... Then decrement the value using the same approach for the delete button.
