More Information

Used on single post permalink pages, this template tag displays a “URL shortening” link for the current post. By default, this will mean the URL has a format of /?p=1234, and will only appear if pretty permalinks are enabled.

However, this feature is limited by design and intended to be leveraged by plugins that may offer links in a different format, a custom format, or even a format provided by a third-party URL shortening service. Refer to get_permalink() if you want to return the permalink to a post for use in PHP.

Note: This function outputs the complete shortlink for the post, to return the shortlink use wp_get_shortlink().
