How to Escape Entities in Comments in WordPress

Are you looking for a way to automatically escape entitles within the code tags for better displaying code? While there’s probably a plugin for this, we have created a quick code snippet that you can use to escape entitles in comments in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

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;
	else
		return $source;
}
add_filter(’pre_comment_content’, ‘escapeEntities’);
