如何在我的网站上创建var然后在另一个页面上显示基于该var的内容？

Question

I'm probably over thinking this, but I have site with various user levels. I'd like to create a specific var (either smarty or in PHP) in my site's header template, then based on this value, display certain code on another page. I've tried several approaches without success. I tried creating a simple function in header.php:

if( $user->level_info.level_name == Basic )
{
$basic_user == yes;
}

Then in video.tpl:

{if $basic_user == yes}
some code
{/if}

It didn't work. I also tried it in smarty (header.tpl)

{if $user->level_info.level_name == Basic}
{assign var="basic_user" value="yes"}
{/if}

Then something like if "var=xx, some code", but honestly I can't even remember how I tried that in video.tpl, but I'm sure it was wrong. Can anyone please help? I'm sure it's simple, but I'm stuck and frustrated. Thanks!

I also just tried this in video.php:

if($user->level_info.level_name != Premium){
header("Location: nopermission.php"); exit();       
} 

And it "works", but all users, no matter if Basic or Premium are forwarded to the no permission page. I am very confused.

For that, I sometimes use session variables with information of user's role.

For example:

$_SESSION['profile'] = 'Basic';

Take a look to session variables. http://www.php.net/manual/en/reserved.variables.session.php

Remember to resume the session in every page in order to access the variables.

session_start();

Using your same code, you can do this:

In header.php:

    if($user->level_info.level_name == Basic){
       session_start();
       $_SESSION['profile'] = 'Basic';
    }

Then in video.tpl:

    session_start();
    if ($_SESSION['profile']=='Basic'){
       //some code
    }
