No External Links In Signature - Please Read For Explanation

[rishel]

Not sure if this has been done.

I am wanting to know if someone has made or could make a script, that disallows links to work in a signature file on a forum, if they lead anywhere else other than the site the forum is on.

For example:

If John Doe was at www.abc.com and he had a signature file in his posts that had a link to www.xyz.com the link would not work.

But if John Doe was at www.abc.com and he had a signature file in his posts that had a link to something else on www.abc.com it would work.

This is to prevent spamming of other sites in the sig file in posts, they can print it out, but not have a link.

Any feedback would be greatly appreciated.

its not really complicated, you just need to have a good grasp of reg expressions.

omg neos back!

couldn't you just just hack the sig submission box with an if/else statement

i.e. with a

PHP Code:

if (strlen $_POST['signature'] = '%abc.com%') {
echo ("$_POST['signature']") } else { 
echo ("signature suspended") } //end conditional 


or (this is the one i've placed my faith in

PHP Code:

if ("isset($_POST['signature'] = '%abc.com%')") {
echo ("$_POST['signature']") } else { 
echo ("signature suspended") }; //end conditional 


not sure if either will work but i was trying to show you my idea/hunch.

I've done this with my chatbox, and also with members with less than 15 posts when they post... I will be coding this for my signature as well this weekend... not hard.

lol i guess i forgot about a using an if to check for a url, but then wouldnt a few varitions that youd have to check first? then allow the sig

[sabret00the]

dunno i think 2 if's could do it, one to check it the sig contains http:// if so then check to see if it's an on-site url, else do nothing, but guesses alround for me.
