Escape entities in comments

Adding this code to the functions.php file of your wordpress theme will automatically escape entities within the <code> tags for better displaying code within your posts.

function escapeEntities($source) {
	$encoded = preg_replace_callback('/<code>(.*?)<\/code>/ims',
	create_function('$matches', '$matches[1] = preg_replace(array(”/^[\r|\n]+/i”, “/[\r|\n]+$/i”), “”, $matches[1]);
	return “<code>” . htmlentities($matches[1]) . “</”.”code>”;’), $source);
	if ($encoded)
		return $encoded;
		return $source;
add_filter(’pre_comment_content’, ‘escapeEntities’);
