Session variables and header("location:xxx");

[webgenius]

I'm designing a small site and I have this structure in mind:

index.php
---------------
login fields. User enters login info. LoginCheck.php is called.

LoginCheck.php
-----------------------
Login info are POST collected and checked in DB. If successful, session variables are set. Then redirected to index.php using header("location:index.php");

In index.php. I'm checking is the session variable is registered. But it looks like the session variable is lost during redirection using header.

Is there any workaround for this?

[php]
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){
// Register $myusername, $mypassword and redirect to file "LoginOK.php"
session_register("myusername");
session_register("mypassword");
header("location:index.php");
}
else {
echo "Wrong Username or Password";
}[/php]

session_register("myusername");

header("location:index.php");
}
else {

}

Ive never used session_register.
Do you start with session_start() on every page?

I have used session_start() only in the login page. I think it is enough to start a session in login page, and not on every page.

You said you have never used session_register. Then how do you work around with session variables? Can you please help me on this?

You need to use session_start(); on every page!

When i use sessions i do this:
[php]
# login.php
session_start();
# log in script
# if(login == successful)
$_SESSION['logged_in'] = true;
[/php]
[php]
# member.php
session_start(); # MUST BE INCLUDED!
if(isset($_SESSION['logged_in']))
{
# member is logged in
}
else
{
# member isnt logged in
}
[/php]
session_start(); has to be on every page that you are using sessions in.
