Sessions and disappearing variables.

[fakeh]

The Problem:
basic login functionality for an admin thing for a webby.

Just needs to login until logout or browser close.

Want to use sessions and have done this successfully before (using same code, hardward, software this time too!)

session_start() seems to be unsetting the iuser and ipass variables which are passed to it by an html form.

The Code:
//some requires here

echo "$iuser - $ipass";
session_start();
echo "$iuser - $ipass";

if(!PHPSESSID){
session_register("iuser");
session_register("ipass");
}elseif(!$iuser or !$ipass){
session_register("iuser");
session_register("ipass");
}elseif(isset($logout)){
session_destroy();
unset($user);
unset($iuser);
}

$chkPass = check_pass($iuser, $ipass);
if($chkPass["val"] != 1){
unset($user);
}else $user = $iuser;

This gives this:

"dan - xxxxxx"

then a warning about not being able to send headers.

When I remove the first echo it gives:

" - "

Hope someone can help. Thanks in advance.

What if you use $_POST['iuser'] instead, assuming the form uses the POST method?

[fakeh]

changed the code:

session_start();
echo $POST["iuser"] . " - " . $POST["ipass"];

there is no difference.

and yes, form does use post.

To help you to debug, toss aside the main code that you're working on for a while, and try to find the smallest script that demonstrates this problem.

Fix the problem in that script, then apply the solution to the main code.
