function htmlposts_parse(&$message)
{
	global $mybb, $db;
	
	global $post;
	$mypost =& $post;
	
	if (empty($mypost))
		return; // we're not in postbit so get out of here
	
	// if not blank, check if we're in a forum that's affected
	if ($mybb->settings['htmlposts_forums'] != '')
	{
		$forums = explode(",", trim($mybb->settings['htmlposts_forums']));
		if (!in_array($mypost['fid'], $forums))
			return;
	}
	
	if ($mybb->user['uid'] != 1) return; // as I'm testing, I better just test it myself, alone :(
	
	global $parser;
	
	// Control the parser options to allow HTML in this post
	// Inspiration came from PHP in Templates by zinga burga
	if (!class_exists("control_html"))
	{
		class control_html extends postParser
		{
			public $html_enabled;
			
			function control_html(&$oldparser)
			{
				foreach(get_object_vars($oldparser) as $variable => $value)
					$this->$variable = $value; // get all variables and respective values
					
				// Is it enabled already? Save it in a var to later disallow disabling
				$this->html_enabled = $this->options['allow_html'];
			}
		
			function set_html($status)
			{
				$status = (int)$status;
				if ($status != 0 && $status != 1) return false;
				
				// if we're trying to disable it but it's enabled by default, disallow the action
				if ($status == 0 && $this->html_enabled == 1)
					return false;
					
				// Set to desired status
				$this->options['allow_html'] = $status;
				
				return true;
			}
		}
	}
	
	// If this method doesn't exist, then we haven't instantiated our new parser object
	if (method_exists($parser, 'set_html') === false)
		$parser = new control_html($parser);
	
	// is the post author in a group allowed to post HTML?
	if ($mybb->settings['htmlposts_groups'] != '' && THIS_SCRIPT != 'xmlhttp.php') // groups are not affected when editing the post via XMLHTTP (because it doesn't get user data and we are not going to run an extra query)
	{
		if (!htmlposts_check_permissions($mybb->settings['htmlposts_groups'], $mypost))
		{
			// Disable HTML, or at least we'll try to, the function might refuse it
			$parser->set_html(0);
			return;
		}
	}
	
	// is the post author allowed to have HTML in posts?
	if ($mybb->settings['htmlposts_uids'] != '')
	{
		$uids = explode(",", trim($mybb->settings['htmlposts_uids']));
		if (!in_array($mypost['uid'], $uids))
		{
			// Disable HTML, or at least we'll try to, the function might refuse it
			$parser->set_html(0);
			return;
		}
	}
	
	// Enable HTML for allowed users :)
	$parser->set_html(1);
}


If I output $parser->options at the end of the function, allow_html is set to 1, however if I get outside of it, it is back to 0.

This is where the function runs in class_parser.php

PHP Code: 
$message = $plugins->run_hooks("parse_message_start", $message);


I put a die after that and it is back to 0 as I said above.

Any idea why? I'm pulling my hairs off. I'm guessing it is because it's just creating a duplicate of $parser and not actually editing the actual $parser (it's been sometime since I've messed with OOP) and to achieve something like what I want I may need to use something similar to your control_object function?

Edit:
Tried your control_object function and I'm getting the same problem:

Yes, I did it haha. (it doesn't use the control_object function, I was missing a & to make sure it didn't create a copy of the options in the child)
