URL redirect in PHP-Nuke 7.6 and backward compatability

For those that distribute scripts, you will want to update them for v7.6, but want to keep them backward compatible with previous versions of nuke. This is how you do it for the admin URL redirect that hides the admin.php filename:

Lets say you have this coded:

Code:

<a target='_blank' href='http://www.google.com'>Google</a>

This will tell google that the referring page is:

Code:

http://www.mysite.com/admin.php

Were not worried that google knows what our admin file has been renamed to, but we are worried about those hackers finding out. We need to hide them. This is what you need to do:

Near the top of the admin file, put:

Code:

global $hideURL;

$sqlV = "select * from ".$prefix."_config";
$resultV = $db->sql_query($sqlV);
$confV = $db->sql_fetchrow($resultV);
if ($confV['Version_Num'] >= '7.6') {
$hideURL = 'index.php?url=';
} else {
$hideURL = '';
}

At the top of each function in the admin file, put:

Code:

global $hideURL;

Where you have every outbound URL, add to the beginning of it:

Code:

".$hideURL."

Like this:

Code:

<a target='_blank' href='".$hideURL."http://www.google.com'>Google</a>

note the single quote before the double quote

This adds index.php?url= before the outbound URL if the version of nuke is 7.6 or higher. For older versions, nothing is added, and the URL looks as it has always looked. An added bonus for this is, if a user now is using nuke less that 7.6, updates your script, then in the future, updates to 7.6 or higher, your script will automatically start using the URL redirect protection.
