[wp-hackers] Mapping meta caps only to attachments and unpublished posts

[William Davis]

I'm trying to allow users to only delete unpublished posts and  
attachments. I removed their meta cap to delete posts and am trying to  
add it back selectively with the code below, but am not having any  
luck. Any help would be much appreciated.

if ( 'delete_post' == $cap ) {
		$post = get_post( $args[0] );
		$post_type = $post->post_type;
		if( $post_type == 'attachment' ) {
			$post_type = get_post_type_object( $post->post_type );
			$caps[] = 'delete_post';
		}
}
