This is the old version I demonstrated. You should go with the later
version that sets the values to the quantity :)
I thought I had? Haven't I?
But this is the easiest shopping cart I have ever seen.
However, I still have not understood what you were doing with these lines I commented out.
if( isset( $_SESSION['TrolleyContents'][$_POST['RNum']] ) )
{
# $_SESSION['TrolleyContents'][$_POST['RNum']] -= 1;
# if( $_SESSION['TrolleyContents'][$_POST['RNum']] <= 0 )
# {
unset( $_SESSION['TrolleyContents'][$_POST['RNum']] );
# }
They did not work, or seem to?
