Include Post Format in permalink

2 comments

1. While researching this topic myself, I found a plugin called Post Format Permalink. However, this plugin is not compatible with recent versions of WordPress; it is also filled with unnecessary code.

   I forked the plugin’s repository on GitHub, and improved the code greatly. I can now use a %post_format% tag in my permalink structure, and that works fine. Mostly.

   The problem is, posts with no post format are displaying as http://example.com/standard/just-another-post, which is not the desired outcome. I’ll keep working on this, and post an update here.

   Here is the code I used. It can also be found on GitHub:

   <?php
   /**
    * Plugin Name: Post Format Permalink
    * Plugin URI: https://wordpress.stackexchange.com/q/70627/19726
    * Description: Include the post format slug in your permalinks. Simply use the <code>%post_format%</code> tag as part of your custom permalink.
    * Version: 1.2

    */
   
   add_filter( 'post_link', 'post_format_permalink', 10, 2 );
   add_filter( 'post_type_link', 'post_format_permalink', 10, 2 );
   
   function post_format_permalink( $permalink, $post_id ) {
   
       // if we're not using the %post_format% tag in our permalinks, bail early
       if ( strpos($permalink, '%post_format%') === FALSE ) return $permalink;
   
       // get the post object
       $post = get_post( $post_id );
       if ( ! $post ) return $permalink;
   
       // get post format slug
       $format = get_post_format( $post->ID );
   
       // set the slug for standard posts
       if ( empty( $format ) )
           $format = apply_filters( 'post_format_standard_slug', 'standard' );
   
       // apply the post format slug to the permalink
       return str_replace( '%post_format%', $format, $permalink );
   }

2. You can add a custom slug to the permalinks via plugin and use this inside your custom permalinks; dont forgett to update the permalinks. It is important, that the rules was refreshed. The follow source is a exmaple for use post format with the string %postformat%, but not perfectly code. Better is to load on hook plugins_loaded and not create a new class, but enough to test and use it now.

   Please check this, current untested. I have write this for long time.
