Re: session_name("CCLTrolley")

Excellent. Thanks. I think I follow what you have done. But to clarify, and learn, what are you doing with -= ? $trolley[$item] -= $quantity; Likewise, i had not followed what you were doing with the lines I commented out. They did not seem to work, and I succeeded in doing what I wanted without them. I'm a prof, as you can tell, and always have a question for an answer ;). Thanks for your time and patience, John //Delete an entry: if( isset( $_SESSION['TrolleyContents'][$_POST['RNum']] ) ) {

  #    $_SESSION['TrolleyContents'][$_POST['RNum']] -= 1;
  #    if( $_SESSION['TrolleyContents'][$_POST['RNum']] <= 0 )
  #    {
          unset( $_SESSION['TrolleyContents'][$_POST['RNum']] );
  #    }

If you go with an array system might I suggest the following change to what I wrote:

I'm resending a better way to do the simple trolley since you seemed to have created a Frankensteinian merge of the two examples I sent previously. if( isset( $trolley[$item] ) ) { $trolley[$item] -= $quantity; if( $trolley[$item] < 1 ) { unset( $trolley[$item] ); } }
