I tried writing my own plugin–less functionality, really just a simple filter plugin with some preg_replace’s to get the most basic wiki markup, but even this isn’t working. Can anyone see what might be going awry here? I’ve tested all the regular expressions in a plain PHP file, so I know they’re working; it’s putting it all into a plugin and getting bbPress to use it that seems problematic.

$mediawiki_filter_params["wiki"] = "http://en.wikipedia.org/wiki/";



/*

Stop editing; actual plugin functionality follows.

function filter_mediawikitext($content) {

global $mediawiki_filter_params;

// BASIC FORMATTING

// Bold and italic

$content = preg_replace("|(''''')(.*?)(''''')|",

"<strong><em>2</em></strong>", $content);

$content = preg_replace("|(''')(.*?)(''')|",

"<strong>2</strong>", $content);

// Italic

$content = preg_replace("|('')(.*?)('')|",

$content);

$count   = 1;

$replace = TRUE;

while ($replace) {

$before = $content;

$content = preg_replace("|([)(.*?)(])|",

"<a>[".$count."]</a>",

$content, 1);

if ($before==$content) { $replace = FALSE; }

$count++;
