WordPress: hide widgets from Post Window programmatically

I'm burning my brain to find someway to hide some widgets from "Post Window" programmatically.

I found an article on WordPress.org that worked fine to hide some widgets from the Dashboard Window (ref.: http://codex.wordpress.org/Dashboard_Widgets_API#Advanced:_Removing_Dashboard_Widgets). But unfortunately I didn't find any way to hide some widgets from Post Window.

I'd like to remove widgets like: Tags, Custom Field开发者_开发问答s and Post Thumbnail.

Can someone help me?

Thank you! Taj Singh

This plugin sounds like it does what you want: WP-CMS Post Control:

Post Control from WordPress CMS Modifications gives you complete control over your write options for every user level/role. It not only allows you to hides unwanted items like custom fields, trackbacks, revisions etc. but also gives you a whole lot more control over how WordPress deals with creating content.

I believe the relevant function called is remove_action(), though I have not dived deep into this area of WordPress yet.

Use remove_meta_box(), see read function docs till the end.
