Here's how we handle [code] blocks. if (preg_match("#\[code\](.*?)\[/code\]#si", $message, $matches)) { $matches[1] = htmlspecialchars($matches[1]) $message = preg_replace("#\[code\](.*)\[/code\]#si", "<!-- BBCode Start --><TABLE BORDER=0 ALIGN=CENTER WIDTH=85%><TR><TD><font size=-1>Code:</font><HR></TD></TR><TR><TD><FONT SIZE=-1><PRE>$matches[1]</PRE></FONT></TD></TR><TR>$ } It formats it quite nicely. The HTML comments in there are just so its easy to remove the HTML and replace it with [code] and [/code] for editing a message. I have functions that replaces all the UBB code type things [b], [i], [url] etc etc. if you want them:) -- James Atkinson ----------------------------------------------------------------- James Atkinson 100world Technical Developer 512-1529 West 6th Avenue phone: +1-604-637-8122 Vancouver, BC, V6J 1R1 fax: +1-604-742-1770 Canada email: james.atkinson@100world.com http://www.100world.com +---------------------------------------------------------------+ | This message may contain confidential and/or privileged | | information.
