Thanks so much for this in depth post. Really saved me on a bad permalink custom post type I had set up. I updated the permalink structure and they all broke. They are fixed now!

There was a question about showing cats and sub-cats in the url, like you can with regular wordpress categories. Of note here is when you register the taxonomy, there is a setting in the rewrite rules to do this. Under rewrite, the argument pair 'hierarchical' => true, turns on allowing /topic/sub-topic/super-sub-topic/, based on your structure, in the example called topic.


register_taxonomy('topic', 'gam_qa',
				array(
					'labels' => array(
						'name' => _x( 'Topics', 'taxonomy general name' ),
						'singular_name' => _x( 'Topic', 'taxonomy singular name' ),
						'search_items' =>  __( 'Search Topics' ),
						'all_items' => __( 'All Topics' ),
						'parent_item' => __( 'Parent Topic' ),
						'parent_item_colon' => __( 'Parent Topic:' ),
						'edit_item' => __( 'Edit Topic' ), 
						'update_item' => __( 'Update Topic' ),
						'add_new_item' => __( 'Add New Topic' ),
						'new_item_name' => __( 'New Topic Name' ),
						'menu_name' => __( 'Topics' ),
					),
					'public' => true,
					'show_ui' => true,
					'hierarchical' => true,
					'query_var' => true,
					'rewrite' => array( 'slug' => 'q-and-a/topic', 'with_front' => true, 'hierarchical' => true ),
					'capabilities' => array(
						'manage_terms' => 'manage_qa_terms',
						'edit_terms' => 'edit_qa_terms',
						'delete_terms' => 'delete_qa_terms',
						'assign_terms' => 'assign_qa_terms'
					)
				)
			);

Then the function you call from. This is a stripped down version, using only the %topic% tag, which will be the name of your custom taxonomy. The code looks for a parent to the topic, and as long as it finds one, adds it to the url.


function gam_qa_permalinks($permalink, $post_id, $leavename) {
			
			$post = get_post($post_id);
			$rewrite_code = array(
				'%topic%'
			);
			
			if ( '' != $permalink && !in_array($post->post_status, array('draft', 'pending', 'auto-draft')) ) {
				
				if ( strpos($permalink, '%topic%') !== false ) {
					$terms = wp_get_object_terms($post->ID, 'topic');
					if (!is_wp_error($terms) && !empty($terms) && is_object($terms[0])) {
						$topics[] = $terms[0]->slug;
						
						$parent = $terms[0]->parent;
						while($parent) {
							$term = get_term($parent, 'topic');
							$parent = $term->parent;
							$topics[] = $term->slug;
						}
						$topics = array_reverse($topics);
						
						$taxonomy_slug = join('/', $topics);
					}else{
						$taxonomy_slug = 'no-topic';
					}
				}else{
					$taxonomy_slug = '';
				}
				
				$rewrite_replace =
				array(
					$taxonomy_slug
				);
				$permalink = str_replace($rewrite_code, $rewrite_replace, $permalink);
			} else { // if they're not using the fancy permalink option
			}
			return $permalink;
		}

You just saved my sanity. I’ve been fighting with these dang ole permalinks/pagination issues for the last week straight.

Great stuff, keep it up and thanks!

Try
‘/features/%year%/%monthnum%/%day%/%feature%’

Very basic error, not sure if I'm being silly. I've put the '// Add filter to plugin init function' at the top of functions and then am using a custom post type called features, followed all your steps above. I want my structure to be features/%year%/%month/%day%/%postname% but I'm just getting a 404 error?

add_action('init', 'feature_register');
 
function feature_register() {
 
	$labels = array(
		'name' => _x('Feature', 'post type general name'),
		'singular_name' => _x('Feature', 'post type singular name'),
		'add_new' => _x('Add New', 'Feature item'),
		'add_new_item' => __('Add New Feature'),
		'edit_item' => __('Edit Feature Item'),
		'new_item' => __('New Feature Item'),
		'view_item' => __('View Feature Item'),
		'search_items' => __('Search Feature'),
		'not_found' =>  __('Nothing found'),
		'not_found_in_trash' => __('Nothing found in Trash'),
		'parent_item_colon' => ''
	);
 
	$args = array(
		'labels' => $labels,
		'public' => true,
		'publicly_queryable' => true,
		'show_ui' => true,
		'query_var' => true,
		'rewrite' => false,
		'capability_type' => 'post',
		'hierarchical' => false,
		'has_archive' => true,
		'menu_position' => null,
		'supports' => array('title','editor','thumbnail', 'comments','trackbacks', 'author'),
		'taxonomies' => array('post_tag'),
	  ); 
 
	register_post_type( 'feature' , $args );
}



// add to our plugin init function
global $wp_rewrite;
$feature_structure = '/features/%year%/%monthnum%/%day%/%postname%';
$wp_rewrite->add_rewrite_tag("%feature%", '([^/]+)', "feature=");
$wp_rewrite->add_permastruct('feature', $feature_structure, false);

Any help appreciated, thanks

Already solved this and it is possible, however when visiting the url, it gives a 404.

I checked the comments, but could not find a good solution for this.

Hi, nice article, but is it possible to use a custom post meta in the permalink?

Sorry, I wrote too soon! I saw you already answered it in the previous comments and that worked for me too. Thanks again for the great info!

Thanks for the info! It worked great to change the permalinks on my custom post type, but I am getting a 404 when I try to view the post? Is there something I’m missing? I’ve tried saving the Permalinks Settings Page, but that hasn’t done anything. Thanks in advance!
