[SOLVED] unset madness

[richrock]

I'm using a $_SESSION array to store some information on images for later comparision, and that's working fine, the remove images from list is fine too, except for one thing:

 

If I have a list of 5 images (the maximum allowed) like this:

Image 1

Image abc

New jpeg

Alt Image

Last Image

 

And try to remove any of teh first four images (Image 1 - Alt Image), the unset function just removes the last image.  I'm sure I've set this up correctly.

 

But is this code correct?

 

if ($_POST['remove'] != NULL) {

if ($_POST['remove'] == 'nothing_a') {
        $key = '0';
    }
    if ($_POST['remove'] == 'nothing_b') {
        $key = '1';
    }
    if ($_POST['remove'] == 'nothing_c') {
        $key = '2';
    }
    if ($_POST['remove'] == 'nothing_d') {
        $key = '3';
    }
    if ($_POST['remove'] == 'nothing_e') {
        $key = '4';
    }

            unset($_SESSION['sess_maker'][$key]);
            unset($_SESSION['sess_location'][$key]);
            unset($_SESSION['sess_year'][$key]);
            unset($_SESSION['sess_image'][$key]);
            unset($_SESSION['sess_type'][$key]);

// Code continues using array_merge and array_pop to reset the array with new values
}

 

Most examples I've seen use unset like this :

 

unset($_SESSION[$key]);

 

Any ideas would be welcome, TIA

So, what have you done to troubleshoot what it is doing? What value is in $key? What value is in $_POST['remove']?

 

Does the structure of your session variable match $_SESSION['sess_maker'][$key]?

turns out that PHP wasn't reading the [$key] value as it was after the $_SESSION['sess_maker'] string... had to work it out another way.. but thanks anyway.  I had explored what the session was outputting before and after this part of the script ran, but the whole thing was a bit of a mess and I started from scratch...  :-\
