WordPress – how to get the slug of your post or page?

Finding out the slug for a page or post is one of the most popular search terms on this blog. I find it a little bizarre that my little function generates so much interest, but that’s just one of the unexpected joys of blogging.

I have decided to follow-up my first post on getting the post slug, taking in to consideration the comments and main use of the function. Hopefully, though a small change, it is an improvement.

I’ve split it into two functions. The first forming the base for the second.

Function: get_the_slug()

function get_the_slug( $id=null ){
  if( empty($id) ):
    global $post;
    if( empty($post) )
      return ''; // No global $post var available.
    $id = $post->ID;

  $slug = basename( get_permalink($id) );
  return $slug;

WordPress appears to be adopting the style of having get_ and the_ function prefixes to get or display content. So here is the complimentary function. I’ve removed some hooks that I don’t think anyone used, instead just applying one (well named) filter.

Function: the_slug()

 * Display the page or post slug
 * Uses get_the_slug() and applies 'the_slug' filter.
function the_slug( $id=null ){
  echo apply_filters( 'the_slug', get_the_slug($id) );

Example use of the_slug() and get_the_slug() functions:

<div id="some-post-container-<?php echo get_the_slug(); ?>">
  The post slug is <strong><?php the_slug(); ?></strong>.

WordPress – the_slug() – Get post slug function

There is no template function (like the_title()) to get the slug of the current post.

There are two ways to do it:

1. Using basename() and get_permalink() to retrieve post slug.

  echo( basename(get_permalink()) ); 

2. Using global $post object to retrieve post slug.

<?php global $post; echo $post->post_name; ?>

I chose the former and added some hooks

3. Fully hookable function to retrieve the post slug

function the_slug($echo=true){
  $slug = basename(get_permalink());
  do_action('before_slug', $slug);
  $slug = apply_filters('slug_filter', $slug);
  if( $echo ) echo $slug;
  do_action('after_slug', $slug);
  return $slug;

This provides you with a simple way retrieve and display the post slug. I find this useful for applying unique CSS ids and classes to my HTML mark up.

<div id="some-post-container-<?php the_slug();?>">

I’d love to hear what you use it for!
