How to get url of a post from admin panel

I want to get post url from the back end edit post page,
the edit post url is : www.ddd.com/wp-admin/post.php?post=1&action=edit
the real post is: www.ddd.com/wp/?p=1

since the user can edit permalink, i need some wordpress parametrs so it will be constant.

Looking for this answer:

 global $post;
 get_permalink($post->ID);

thx all

You can get the ID of the post you’re editing like this:

//currently edited post id 
$cep_id = $_GET['post'];
//permalink
get_permalink( $cep_id );

This is and can only work if your editing an existing/saved post. It won’t and can’t work on »Add New«-Pages, because the post you’re going to add isn’t saved to the database yet, after »Publish« has been pressed one gets redirected to the actual »Edit«-Page and the above is possible.
