remove_post_type_support() │ WP 3.0.0

Removes the registered capability from the specified post type.

The capability is registered in the supports parameter of the register_post_type() function.

Usually, the capability is simply responsible for displaying the meta box. But there are other capabilities, for example:

• revisions - besides displaying information about revisions in the admin, it determines whether to enable the revision functionality (saving post revisions) for the post type.
• comments - determines whether to display the number of comments on the post editing page.

No Hooks.

Returns

null. Nothing.

function remove_editor_init() {

	// If not in the admin, return.
	if ( ! is_admin() ) {
	   return;
	}

	// Get the post ID on edit post with filter_input super global inspection.
	$current_post_id = filter_input( INPUT_GET, 'post', FILTER_SANITIZE_NUMBER_INT );
	// Get the post ID on update post with filter_input super global inspection.
	$update_post_id = filter_input( INPUT_POST, 'post_ID', FILTER_SANITIZE_NUMBER_INT );

	// Check to see if the post ID is set, else return.
	if ( isset( $current_post_id ) ) {
	   $post_id = absint( $current_post_id );
	} else if ( isset( $update_post_id ) ) {
	   $post_id = absint( $update_post_id );
	} else {
	   return;
	}

	// Don't do anything unless there is a post_id.
	if ( isset( $post_id ) ) {
	   // Get the template of the current post.
	   $template_file = get_post_meta( $post_id, '_wp_page_template', true );

	   // Example of removing page editor for page-your-template.php template.
	   if (  'page-your-template.php' === $template_file ) {
			remove_post_type_support( 'page', 'editor' );
			// Other features can also be removed in addition to the editor.
