very helpful, thanks 👍

many thanks

thanks!

Brilliant. This was exactly what I was after. I was getting annoyed at it being on every custom post type. Thank you!

Thanks! These guys are fucking dickheads for putting that on every post type!!!

Super helpful and just what I needed. Thank you!

Thanks mate

Thank you so much. I was getting frustrated seeing this everywhere and various similar attempts of mine were just not working.

Also, if anyone is using this for removing other annoying metaboxes put by plugin creators that assume you want thier metaboxes in all of your CPT edit pages, check if the metabox is in the normal-sortables div, or the advanced-sortables div. If it is in advanced-sortables, just change the last parameter to 'advanced'

example:
remove_meta_box('page-links-to', $post_type, 'advanced');

Note to plugin developers: Please consider the effect of your cool ideas on other plugins that may be using Custom Post Types. Either limit the effect of your metaboxes by explicitly attaching them to the post type, or allow the toggling of them in other CPTs.

Thanks again!

complemented to woocomerce products, categories, etc with post types in this page https://docs.woocommerce.com/document/installed-taxonomies-post-types/

add_action( 'do_meta_boxes', 'remove_revolution_slider_meta_boxes' );

Thanks !

The do_meta_boxes filter is run 3 times for every editor page load. Once for each context.

So using jcorreia's example from the woocommerce docs, it will call remove_meta_box 36 times (3 * 12) and most of those calls are unneeded. All 36 of them are unneeded if you aren't even on one of those post types. You only need to remove the metabox when you are opening one of the editors for those particular post types.

There are 3 parameters sent in the do_meta_boxes filter.

So add the action this way:
add_action( 'do_meta_boxes', 'remove_unwanted_metaboxes', 10, 3 );

And then do something like this:

function remove_unwanted_metaboxes( $type, $context, $post ) {
	// This action will be executed for all context: normal, advanced and side
	// If you want to run it only for the normal context, you can.
	if ( 'normal' !== $context ) return; // Remove this line and it will check all contexts in case the box has been moved by user

	// get_current_screen() is defined on most admin pages, but not all.
	// The ones that don't have it won't have metaboxes we care about.
	if ( function_exists( 'get_current_screen' ) ) {
		$curPostType = get_post_type();  // Get the current posttype
		$postTypesToCheck = array( 'posttype1', 'posttype2', 'page' );  // PostTypes hiding this metabox. This could be an object var from $this
		if ( in_array ( $curPostType, $postTypesToCheck ) ) {
			remove_meta_box( 'wpseo_meta', $curPostType, $context );
			remove_meta_box( 'postcustom', $curPostType, $context );
			remove_meta_box( 'rs-addon-typewriter-meta', $curPostType, $context );
			remove_meta_box( 'mymetabox_revslider_0', $curPostType, $context ); // Could add _1 _2 etc in case of multiple sliders per page
		}
	}
}

@brianlayman, did you forgot to set the $postType?

like:

 function remove_unwanted_metaboxes( $type, $context, $post ) {
	// This action will be executed for all context: normal, advanced and side
	// If you want to run it only for the normal context, you can.
	// Remove this line and it will check all contexts in case the box has been moved by user
	if ( 'normal' !== $context ) return; 

	// get_current_screen() is defined on most admin pages, but not all.
	// The ones that don't have it won't have metaboxes we care about.
	if ( function_exists( 'get_current_screen' ) ) {
		//get the current post type to use in the in_array()
		$postType = get_post_type();
		// PostTypes hiding this metabox. This could be an object var from $this
		$postTypes = array( 'posttype1', 'posttype2', 'page' ); 
		if ( in_array ( $postType, $postTypes ) ) {
			remove_meta_box( 'wpseo_meta', $postType, $context);
			remove_meta_box( 'postcustom', $postType, $context );
			remove_meta_box( 'rs-addon-typewriter-meta', $postType, $context );
			remove_meta_box( 'mymetabox_revslider_0', $postType, $context ); // Could add _1 _2 etc in case of multiple sliders per page
		}
	}
}

in addition to the solution from @brianlayman, if you have Revolution slider version 6, the metabox ID == 'eg-meta-box'

@Mark-Creeten
Ah, yes, my original code had a different condition. So I edited that sample in the gist text editor and didn't test the edit on a site. Thanks for catching that.

Slider Revolution version 6.5.19, the meta box slug is slider_revolution_metabox and its context is side. So wherever you put it, the call needs to be:

remove_meta_box('slider_revolution_metabox', $post_type, 'side');

Slider Revolution version 6.5.19, the meta box slug is slider_revolution_metabox and its context is side.

In my example then, the context check could handled as a switch clause to have the remove_meta_box calls still only execute once for each appropriate context.
