[SOLVED] Losing it!

[jeffrydell]

Literally ... I'm 'losing' my arrays and I can't figgr out why.

 

One script (we'll call it script.php for now) does 3 things (with a session initiated each time you 'hit' the script):

 

First time in (get), I session_register() each array and set up all the needed array keys/values with " ", so they 'exist' because they'll be default values in an .html form.

 

include('form.html');

 

The form's action is 'script.php?action=show'

 

Second time in (show) it displays all the $_POST variables, adds the $_POST values to the appropriate Arrays, then displays an identical table using the arrays (so I can see that the values got transferred from $_POST to arrays properly.

 

At the bottom of that page, there's a link to call the script a THIRD time (script.php?action=edit) - allowing the user to 'edit' the choices they made in the form.  This is where we lose everything.  On the third time in to the script, I can't get any values from the arrays.

 

See it in action here:

Any ideas?  I've done this type of thing MANY times before and never had trouble 'losing' arrays or variables like this.

 

Thanks!

Please post some code so we can help troubleshoot. Thanks.

Here you go:

 

<?

session_start();

 

if (!isset($_SESSION['action']))

{

$_SESSION['action'] = "get";

 

}

else

{

if (!isset($_GET['action']))

{

$junk = "nothing";

}

else

{

$_SESSION['action'] = $_GET['action'];

}

}

 

switch ($_SESSION['action'])

{

case "get":

session_register("Entry");

session_register("Classes");

session_register("Divisions");

session_register("Levels");

session_register("Trial1");

session_register("Trial2");

session_register("Trial3");

session_register("Trial4");

$count = 1;

$Entry['category'] = " ";

WHILE ($count <= 10)

{

$Classes[$count] = " ";

}

[Foser]

just do

 

<?php

$_SESSION['user'] = username;
?>

to set the session instead of register session. I never really used Register session.

I never had problems with my way of setting up sessions. Hope this works!

[jeffrydell]

Foser,

 

Thanks for the tip!

 

I'm not really setting the session with session_register(), I'm 'setting' it with the session_start(); at the top of the script (at least I think that's the way it works).

 

I'm using the session_register('ArrayName') to make those arrays available across scripts ... like the $_SESSION[] array.  This is a part of a much larger application that will walk people through an 'interview process' similar to online tax prep services, etc.  Each subject area has its own script, sometimes broken out depending on the organizations involved and different business rules requiring different data.

 

Please let me know if there's a better way to make those arrays available for as long as the visitor is in the session.

Anyone else?  Lots of you lookin - still no answer!??!

Is register globals on or off?  Might have something to do with it, as you are not referring to the variables with the $_SESSION['variable'] name syntax but relying simply on $variable_name.  If register globals is off then these values would be empty.

Try this link for working with storing arrays in sessions.

This script didn't work in my 'test' environment, but when I put it in the full project it worked fine ... so whatever it was isn't important right now.

 

Maybe someday I'll pay the price for not figuring it out now ... but for the time being, I'm moving on.  Thanks for your help anyway!
