get_permalink ( int|WP_Post $id, bool $leavename = false )

Retrieve full permalink for current post or post ID.

Return: (string|false) The permalink URL or false if post does not exist.

Source file: wp-includes/link-template.php

Parameters

$id

(int|WP_Post) (Optional) Post ID or post object. Default current post.

$leavename

(bool) (Optional) Whether to keep post name or page name.

Default value: false


Explanation

In a Plugin or Theme, it can be used as early as the setup_theme Action. Any earlier usage, including plugins_loaded, generates a Fatal Error.

Note that when used outside The Loop on a posts page (index, archive, etc.) without the ID parameter, it will return the URL of the last post in The Loop, not the permalink for the current page.

User Contributed Notes

  1. Default Usage
    The permalink for current post (used within The Loop). As the tag does not display the permalink, the example uses the PHP echo command.

    Permalink for this post:

    echo get_permalink();
    
  2. Link to Specific Post
    Returns the permalinks of two specific posts (post IDs 1 and 10) as hypertext links within an informational list.

    <ul>
    	<li><?php esc_html_e( 'MyBlog info:', 'textdomain' ); ?>
    		<ul>
    			<li><a href="<?php echo esc_url( get_permalink(1) ); ?>"><?php esc_html_e( 'About MyBlog', 'textdomain' ); ?></a></li>
    			<li><a href="<?php echo esc_url( get_permalink(10) ); ?>"><?php esc_html_e( 'About the owner', 'textdomain' ); ?></a></li>
    		</ul>
    	</li>
    </ul>
    
  3. Pass in a post object instead of an ID
    This shows how you can you can get the permalink with the page title instead of the ID.

    <a href="<?php echo esc_url( get_permalink( get_page_by_title( 'Monthly Events' ) ) ); ?>"><?php esc_html_e( 'Monthly Events', 'textdomain' ); ?></a>
