Function Reference/url to postid

Contents

Description

Retrieve id of page/post given its url, or zero on failure. Can be thought of as the opposite function of get_permalink.

Note that this function does not return the post id for custom post types (see Trac ticket #19744).

When using this function to retrive the ID of an attachment, it is required that the url provided be in the format of example.com/?attachment_id=N and will not work with the full URL. To get the id from the full URL see this for a work around.

Usage

 <?php $postid = url_to_postid( $url ); ?> 

Parameters

$url
(string) (required) The permalink to check.
Default: None

Return Values

(int) 
ID of the post or page that resides at the given URL, or 0 on failure.
