How to stop cross linking of attachments within forum?

[Sweet Cheeks]

I searched around the hacks dbase and could only find hacks that prevented hotlinking from outside the site. Perhaps I missed one, but what I am looking for is a hack to prevent cross linking from within the forums?

My problem is users are posting a "test" thread in our tech forum, then linking to that attachment and using it in their sigs aranoid: Any ideas on how to take care of this?

Thanks for your help

I will look into it, I am sure it is a very small hack. I have seen it done on a few other sites.

Cool Neo, thank you

any update on this?

There is an option in the vB options to prevent the img tag being used with ? , when set to prevent this, these sigs will no longer work, and most likely they will stop trying.

In members.php

Find:

PHP Code:

  $signature=htmlspecialchars($bbuserinfo[signature]); 


Above it, add:

PHP Code:

    if (strstr($signature,'attachment.php')) {
      eval("standarderror(\"".gettemplate("error_noattachmentallowed")."\");");
      exit;
    } 


Then ADD a NEW template called "error_noattachmentallowed" with the contents:

No attachments allowed in signature.

Not tested, but should work...
