session _register

[Phlexus]

Hi all,

I have this problem, but since I don't know enough about PHP I need your help. Look at the code below:

<?php
session_unregister ("default_categoriekeuze");
session_unregister ("persoon");
session_unregister ("model");

include ("/usr/local/plesk/apache/vhosts/XXXXXXX.nl/httpdocs/support.inc");

$form_default_start = "Form_DefaultStart.inc";
$form_default_end = "Form_DefaultEnd.inc";
$form_persoon = "Form_Persoon.inc";
$form_model = "Form_Model.inc";

if (isset ($persoon["voornaam"]))
$persoon=array();

/ Set default form to include. /
if (!isset ($form_categorie))
$form_categorie = $form_model;

/ Set categoriekeuze in case it isn't set /
if (!isset ($default_categoriekeuze))
$default_categoriekeuze = "$script_thema";

/ Depending on default_categoriekeuze, set form_categorie and dbinfo['table_categorie'] /
session_register ("table_categorie");
if ($default_categoriekeuze == "$script_thema") {
$form_categorie = $form_model;
$table_categorie = $dbinfo["table_model"];

}

$title = "XXXXXXXX: Zoeken";

if (!isset ($search)) {
include ($headerfile);

session_unregister ("default_categoriekeuze");
include ($form_default_start);
session_unregister ("default_categoriekeuze");

include ($form_persoon);
include ($form_categorie);

include ($form_default_end);

include ($footerfile);

session_unregister ("default_categoriekeuze");
}
else {
session_register ("default_categoriekeuze");
session_register ("persoon");
session_register ("model");

$persoon["foto"] 						= $persoon_foto;
$persoon["geslacht"] 					= $persoon_geslacht;
$persoon["leeftijd_richting"]				= $persoon_leeftijd_richting;
$persoon["leeftijd"]					= $persoon_leeftijd;
$persoon["leeftijd_range"]				= $persoon_leeftijd_range;
$persoon["plaats"] 					= $persoon_plaats;
$persoon["provincie"] 					= $persoon_provincie;

$model["lengte_richting"]				= $model_lengte_richting;
$model["lengte"]						= $model_lengte;
$model["lengte_range"]					= $model_lengte_range;


header ("Location: $search_script");

}
?>

The session_register and session_unregister cause an error. I think it's due to the serverconfig because the same script on another server works just fine. How can I get around the session_register bit? Can anyone help me with this?

I read something about $_session?

Thankz Phlexus

yeah, you're on the right track. session_register wont work if register_globals is set. There are 2 things you can do here, and they are to re-code the script, so that it uses the newer way to use sessions (much more secure), or to get your host to turn the configuration directive register_globals on.

I would suggest having a bit of a read here: http://www.php.net/manual/en/ref.session.php

[Phlexus]

Thanks, but I've read the part on php.net before I posted this question and I didn't understand what to do. I'm not a programmer. Could you give me some example of how to recode it, or give me a sense of direction?

[Phlexus]

What's odd is that register_globals is turned on. So what could be causing the error then?

[matt_4013]

Yeah, the fact that register_globals is turned on is the problem. I don't have time to look at it now, but if you can wait a day or 2, send me a private message and I'll see what I can do.

Use $SESSION[variable] = $variable; instead of session_register. After that, $SESSION[variable] becomes an accessible variable itself, ie., you can do echo $_SESSION[variable]; to print it out.

[paul088]

By the way, I don't see session_start(); in your script. Put that on very top of your script.

[Phlexus]

Correct, session_start is defined in support.inc.

But I think I have tackled the problem. There was some code commented and after uncommenting is the script seemed to work ok.

Thanks for your help. On to the next weird problem :-)
