get_single_template()

Retrieve path of single template in current or parent template. Applies to single Posts, single Attachments, and single custom post types.

Description

The hierarchy for this template looks like:

  1. {Post Type Template}.php
  2. single-{post_type}-{post_name}.php
  3. single-{post_type}.php
  4. single.php

An example of this is:

  1. templates/full-width.php
  2. single-post-hello-world.php
