How to block non-admin direct access to admin panel of discuz

We are thankful to Mourad for this tutorial. 

As we know Discuz default configurations allow anyone to access the admin page by directly accesing that url www.example.com/admin.php

So to prevent non-admin to direct access the admin page just open "admin.php" with a text editor and search for:" $discuz->init(); "

Newline, and just add the following code:

if(!$_G['uid'] || !getstatus($_G['member']['allowadmincp'], 1)) {
header('Location: /');
}



then save the file that all.

Now if non-admin try to access the admin page they will be redirected to the home page, and if you would redirect them to any other page (like a  external page or a fake admin page) just change the slash " / " by your link.
