I can write this and get the right results:

if ( $_SESSION['addId'] == 'add[4]' )
$productId = 1;
if ( $_SESSION['addId'] == 'add[5]' )
$productId = 2;
if ( $_SESSION['addId'] == 'add[6]' )
$productId = 3;

But if I try to streamline it by writing it this way, it doesn't work:

if ( $_SESSION['addId'] == 'add[$i]' )
$productId = $i;

I think the two methods should be equivalent so why doesn't the second way work?

Play with the quotes. Try using double iinstead.

I'd use an preg match

preg_match("/add\[(\d)\]/", $_SESSION['addId'], $match);
$productId = $match[1];

All of the problems that I've been writing about lately had to do with the fact that I was using nine image buttons and just one form. Once I put form tags around all of my image buttons individually the problems went away.
