Session not saving a particular variable.

relytjj

I am trying to save this session array known as $SESSION['size'] but each time it revisits this page the variable is empty. Cosider $POST['same_size'] as always set. Here is a snippet of the code:

if ($_POST['acc_']) {
        foreach ($_POST['acc_'] as $key => $value) {
                if ($_SESSION['acc_'][$key]){
                                if ($_POST['action'][$key] == 'Change' ) {
                                        $_SESSION['acc_'][$key] = $value;
                                } else {
                                        $_SESSION['acc_'][$key] += $value;
                        }
                } else {
                        $_SESSION['acc_'][$key] = $value;
                }

            if ($_SESSION['acc_'][$key]<=0)  {
                    unset ($_SESSION['acc_'][$key]);
            }

            if(empty($_SESSION['size'])) {
                    $_SESSION['size'] = array();
            }

            if ($_POST['same_size']) {
                    $_SESSION['size'][$_POST['pid'].$_POST['select_size0']] = $_POST['pid']."|".$_POST['select_size0']."|".$valu
e;
                        print_r($_SESSION);
                }      

}

The session arrays 'acc' and 'tr' are properly updated and saved but not the $_SESSION['size']. There are no unset calls in any of the other various pages one could traverse.

I don't get it, any ideas?

Try:

$SESSION['size']["'".$POST['pid'].$_POST['select_size0']."'"] . . .

That didn't work Brett. I also tried storing that string in a variable and then putting the variable in place and it didn't work. Thanks for the suggestion though.

I just have no idea why it is saving the acc and tr arrays and not the size array. Is there something obvious I am missing?

Have you also tried:

$SESSION['size'] = array($POST['pid'].$POST['select_size0'] => $POST['pid']."|".$_POST['select_size0']."|".$valu);

See if that works. Otherwise, I'd be thinking that the size value of the session array is reserved.

This seems unnecessarily complicated. If you're using the pid and select_size0 as array keys, then why store them in the value as well? Also, if you're using pid and select_size0 as array keys, why not use them as separate array keys, rather than joining them together to make one?

$_SESSION['size'][ $_POST['pid']][ $_POST['select_size0']] = $value;

Contains all of the same information, and more accessibly (since you don't need to mess around with breaking strings up). It's also simpler and less prone to typos.

I would also note that even if the $SESSION['size'] array is getting values, only the last $value would be stored: whatever values are already there would get overwritten every time the loop iterates. Perhaps you want

$_SESSION['size'][$_POST['pid'].$_POST['select_size0']][] = $_POST['pid']."|".$_POST['select_size0']."|".$valu
e;

(Or

$_SESSION['size'][ $_POST['pid']][ $_POST['select_size0']][] = $value;

All this of course assumes that $POST['pid'] and $POST['same_size0'] have their proper values.
