Filter pre tags in bbPress

A couple of functions used at htaccessbook.com to enable unescaped/unencoded pre and code tags in bbPress forum posts.

function bbp_replace_brackets($content) {
	$filter_pre_content  = preg_replace_callback('#\<pre\>(.+?)\<\/pre\>#s', create_function('$matches', 'return "<" . "pre>".htmlentities($matches[1])."</pre" .">";'), $content);
	$filter_code_content = preg_replace_callback('#\<code>(.+?)\<\/code\>#s', create_function('$matches', 'return "<" . "code>".htmlentities($matches[1])."</code" .">";'), $filter_pre_content);
	return $filter_code_content;
add_filter ('bbp_get_topic_content', 'bbp_replace_brackets', 9);
add_filter ('bbp_get_reply_content', 'bbp_replace_brackets', 9);

To implement this technique, add the code to your theme’s functions.php and done. Once in place, this function will ensure that pre and code tags are not removed/encoded/escaped by bbPress.

If you are not concerned about code tags, here is a simpler function that will ensure that pre tags are allowed in forum posts:

function bbp_allow_pre_tags(){
	global $allowedtags;
	$allowedtags['pre'] = array();
add_action('init', 'bbp_allow_pre_tags');

No editing is required for either of the functions presented in this tutorial to work. Just plug ’n play, and be sure to test the results.
