How to get post id from permalink (pretty url)?
You should be fine with url_to_postid()[see documentation] which is located in rewrite.php. I used it in a plugin of mine last year, works like a charm.
I've got a dedicated (& documented) function for that:
get_page_by_path( $page_path, $output, $post_type );Retrieves a page given its path.
Where $page_path is
[...] the equivalent of the 'pagename' query, as in: 'index.php?pagename=parent-page/sub-page'.
See Function Reference/get page by path
Example:
// Assume 'my_permalink' is a post.// But all types are supported: post, page, attachment, custom post type, etc.// See http://codex.wordpress.org/Post_Typesget_page_by_path('my_permalink', OBJECT, 'post');
This works for regular post types AND custom post types. url_to_postid() only works for regular posts.
