Disallow URL in guestbook post?

zaziboff

Do anybody know how I can disallow people from writing URL in a post? Somehow check the input for http and/or www and deny it..

<?php

// block person with IP-number from a page
$remote = $_SERVER["REMOTE_ADDR"];
if($remote == "77.217.83.19" ||
$remote == "153.12.97.34" ||
$remote == "19.124.5.212" )
{
    header('location: pageforbanned.php');
    exit;
}

//////////////////////
// or you can just exit and give a message
exit( 'you are not allowed to access guestbook' );

I see now, this was not what you asked for.
But anyway I let it be.

hi again

This is what I use in a script of mine.
Now, can also be https:// ( secure serverpage )
so we may add a test for this, too

<?php

$page = 'string to be tested';

// test for link:   www.  OR  http:// OR WWW.  OR  HTTP://
if( stristr($page, 'www.') || stristr($page, 'http://' ) ){

// is a link or domain name

}

?>

http://php.net/stristr ( insensitive to UPPER/lower case )
http://php.net/strstr
( uses UPPER/lower match case, so search for 'http://' will not find 'HTTP://' )
