trouble with $HTTP_SESSION_VARS

[Genghis]

i have a problem where the $HTTP_SESSION_VAR is not being tranfered on the second page. When i print the $user variable on the first page it is there, however when i try to print it out on the second page it is empty.i am using php version 4.02.

any help would be appreciated.

 // First page
<?php
   session_start();  

   $user = "Daniel";
   ECHO $user;
   session_register('user');

   printf("<a href=\"%s\">%s</a><br>",
            "2.php","2nd page");

?>

// This is second page.

<?php

   session_start();
   ECHO "user is";
   ECHO $HTTP_SESSION_VARS['user'];

?>

You only registered the variable with session_register but you did not set its value. The variable is still empty. The session_register function only registers a variable, it does not set its value, details on the session_register function can be found here: http://www.php.net/manual/en/function.session-register.php

Also since you are using sessions, you do not need to use HTTP_SEESION_VAR to access session variables. Here is an easier way to accomplish your task:

<?php

session_start();

$user = "Daniel";

session_register('user'); //Register a variable called user
$_SESSION['user'] = $user; //Set the session variable user (which was registered above) to the value in the local variable $user

//Add your link to the next page here
?>

<?php
//next page
session_start();

echo $_SESSION['user'];

?>

That should work.

Good luck.

i see how it works now. The register creates the variable but you still have to assign it ... thanks for your help!
