[Plugin: IM8 Box Hide] This error occurs when accessing the plugin!

to fix, replace

foreach($wp_meta_boxes['post'] as $context)
			foreach($context as $priority)
				foreach($priority as $box)
					array_push($this->postboxes,array($box['id'],$box['title']));

		foreach($wp_meta_boxes['page'] as $context)
			foreach($context as $priority)
				foreach($priority as $box)
					array_push($this->pageboxes,array($box['id'],$box['title']));

with

if ($wp_meta_boxes['post']) {
		foreach($wp_meta_boxes['post'] as $context)
			foreach($context as $priority)
				foreach($priority as $box)
					array_push($this->postboxes,array($box['id'],$box['title']));
	}
	if ($wp_meta_boxes['page']) {
		foreach($wp_meta_boxes['page'] as $context)
			foreach($context as $priority)
				foreach($priority as $box)
					array_push($this->pageboxes,array($box['id'],$box['title']));
	}

ie, wrap foreach with condition check, if ($wp_meta_boxes[‘page’]) { ….

Hi,

Small errors too on lines 45 and 48 of im8-box-hide.php:

Replace:

foreach ($hide[$user_role]['post'] as $box => $value)
			foreach (array('normal', 'advanced', 'side') as $context) remove_meta_box($box, 'post', $context);

		foreach ($hide[$user_role]['page'] as $box => $value)
			foreach (array('normal', 'advanced', 'side') as $context) remove_meta_box($box, 'page', $context);

with

if($hide[$user_role]['post']){
		foreach ($hide[$user_role]['post'] as $box => $value)
			foreach (array('normal', 'advanced', 'side') as $context) remove_meta_box($box, 'post', $context);
		}

		if($hide[$user_role]['page']){
		foreach ($hide[$user_role]['page'] as $box => $value)
			foreach (array('normal', 'advanced', 'side') as $context) remove_meta_box($box, 'page', $context);
		}

Seems to fix the similar issues (this is on WordPress 3.0 btw).

Will you be implementing options for custom post types? Just a thought – I manage them myself at the moment and create/hide the meta boxes when I actually create the custom post types, but others may find this handy! Thanks for a great plugin.
