Code to prevent linking from specific site(s)

Ok, I have not tested this but here it goes.

change the if() statement from my previous post to this:

$vb_org = 0;
if(strstr($url, "http://www.vbulletin.org")) {
  $vb_org = 1;
}

In showthread.php there are 2 instances of the following code:

$getperms=getpermissions($thread['forumid'],-1,-1,$forum['parentlist']);

Insert the following code directly below both of them:

if($vb_org == 1) {
  $getperms['canview'] = 1;
}

This should allow a one time temporary view permission to VB.org visitors.

Thank you, sir.

Will this allow the view of the link only from here or can they view the rest of the site after getting in this way?

[Zzed]

Just the link. The visitor gets a one time permission to view the contents of the link. Any further navigation will be prevented.

[Boofo]

Ok, installed and will test.

[Zzed]

Cool.

Please let me know how it works.

[Boofo]

Ok, I just tried it it I get a "No hot linking allowed" because I have that in my attachment.php and avatar.php at the top. Anyway to bypass that just for the link?

[Zzed]

avatar.php is not using global.php. So you may want to add the same logic as in global.php. Except that you have to use $REMOTE_ADDR instead of $url.

In attachment php:
Look for:

$permissions=getpermissions($getforuminfo[forumid]);

And add this directly below it:

if($vb_org == 1) {
  $permissions['canview'] = 1;
  $permissions['cangetattachment'] = 1;
}

Still giving me the same error. Here is the code at the top of the file to prevent hot-linking.

PHP Code:

/////////////////////////////////// Start of Avatar/Attachment Protector ///////////////////////////////////

$referers = array ('www.bearfacts2.com','bearfacts2.com','66.250.216.66');

function check_referer($referers){
   if (count($referers)){
      $found = false;
      $temp = explode('/',getenv("HTTP_REFERER"));
      $referer = $temp[2];
      for ($x=0; $x < count($referers); $x++){
         if (ereg ($referers[$x], $referer)) {
            $found = true;
         }
      }
      if (!$found){
      echo "No hot linking allowed!";
      exit;
      }
         return $found;
      } else {
         return true;
   }
}

check_referer($referers);

You may want to add 205.214.66.221 and www.vbulletin.org to your list of referrers.

Still couldn't get it to work for messages. Thanks anyway, buddy.

Edit: Finally got it working. Thanks Edwin. I have the "guests not allowed to view threads" hack by PPN installed and had to work around that.

One last question. How do I add more than one IP or site address to the line so I can add more instead of having to do it for each separate address?
