Problem with sessions

[armandocerna]

I am having a problem putting an array in a session. If you look at line 34 or so when it gets into all of the session code. The line if (!session_is_registered('airportarray')) { is always true even if it is the second time around and the array exists. Basicly it never gets to the ELSE portion of that if statement. Thanks for any help you can offer me

You can try something with superglobals like if (isset($_SESSION['airportarray'])) {

I'm pretty sure in current versions of PHP you don't have to register session variables manually anymore. They automatically get handled when you address the variable directly.

Then again, that might just be sloppy coding practices on my part, but it works.

Nope, using the $_SESSION superglobal is the preferred method.

Um, try this..

// Replace this:
if (!session_is_registered('airportarray')) {   // LINE 34
   session_register('airportarray');
   $airportarray = array();
   $airportarray[0] = $airport;

// With this:
if (!session_is_registered('airportarray')) {   // LINE 34
   $airportarray = array();
   $airportarray[0] = $airport;
   $_SESSION['airportarray'] = $airport;

I think this is what you're looking for heh..
