Hey! I am going to being building a forum system very soon. One thing though that I am wondering is how you would parse (and also add into posts) the ubbc code that the user posts......any suggestions? links? Your help would be appreciated.

Bit of java script to put the code in the text box (so its user friendly!)

store that directly in your database then when outputting content to the screen do a regular expression replacement of the tags for your html tags.

quickie...

OK you have doen teh javascript to place stuff like [b]BOLD[/b],[h1]Header[/h1] into the text area adn teh the whole string has been saved in the database.

You want to replace [b]SOME TEXT[/b] with bold tags adn same for h1

now you could do a string replace on just the '[' and the ']'
[code]<?php
$string = "[b]some bold text[/b] at the start of teh post.";

$lookfor = array('[', ']');
$replacewith = array('<', '>');
$string = str_replace($lookfor, $replacewith, $string);
?>
[/code]
or you could do similar with regular expressions...
[code]<?php
$lookfor = array('/[b](?!\[)[/b]/','/[h1](?!\[)[/h1]/');
$replacewith = array('<b>\\1</b>', '<h1>\\1</h1>');
$strinng = preg_replace($lookfor, $replacewith, $string);
?>
[/code]

It takes too long to explain regular expressions so juts go and find a good tutorial on them.....
