I have installed BBcode lite, and I want to add my own custom bbcode tag, I tried making my own plugin to allow [tex][/tex], though I can still not fully understand the preg_replace() function. Would be greatly appriciated with some help.

What I am trying to achieve is:

[tex]some code here[/tex]…

The code in between the tags get’s converted to <img class=”latex-image” src=”/path/image.cgi?#code goes here with urlencoding#” alt=”” />

If it’s not too complicated to make the standard plugin to put code tags from the bbcode tags into additional pre tags when outputted, that would be great too.

[code] tags into additional pre tags when outputted, that would be great too.

I made it work in a way using this:

<?php

/*

Plugin Name: BBTexCode

Description:  [tex][/tex] to image

Plugin URI:

Author:  Sondre Kjøniksen

Version: 1.00

*/



function bb_tex_replace( $text ) {

$text = preg_replace('/[tex](.*?)[/tex]/ie', "'<img src="/cgi-bin/mathtex.cgi?'.rawurlencode('$1').'" align="middle" />'", $text);

return $text;

}

add_filter('post_text', 'bb_tex_replace');

?>

Though I still have a problem, it seems bbpress strips backslashes when adding the post to the DB. Is it possible to do so bbpress skips stripping backslashes from [tex][/tex] tags? At the moment it works if I write double backslashes like: [tex]\LaTeX \frac12[/tex] But it is kind of annyoing having to type double every time.

Edit, this seems to only apply when I use override posting restrictions from the admin-can-post-anything plugin.
