Lang: php var name:$id issue:session not staying registered?

Question

page 1:

<?php

//register any session vairables

session_start();

session_register("id");

$id=$row["id"];

?>

page 2:

<?php

session_start();

$_SESSION['id'];//creates session variable

//check to see if the user is logged in this will be done each time on any internal page

Print_r ($_SESSION);

?>

output:

Array ( [id] => 1 [] => )

Why won't it keep me logged in?

Answer 1

geek,

try setting $id=$row[&quot;id&quot;];

before calling session_register(&quot;id&quot;);

Also, this is from Php.net:

// Use of session_register() is deprecated

$barney = &quot;A big purple dinosaur.&quot;;

session_register(&quot;barney&quot;);

// Use of $_SESSION is preferred, as of PHP 4.1.0

$_SESSION[&quot;zim&quot;] = &quot;An invader from another planet.&quot;;

Answer 2

For a start you are declaring a variable in one page, then re-decalring it on the second page, this would clear it. Better is :

&lt;?php

session_start();

$_SESSION[id] = whatever you want.

?&gt;

In any further pages you can simply read it :

&lt;?php

$[id] = $_SESSION[id];
