Permalinks help WordPress

Milan Petrovic answers:

WordPress for custom post types allows only one form of permalink that includes post type name (or custom slug) and post name.

My plugin GD Custom Posts And Taxonomies Tools Pro allows settings custom permalinks for each custom post type that can include taxonomies, date elements and other things, just like WordPress does for normal posts:

Fahad Murtaza answers:

In register_post_type('work', array(...

Did you use

'rewrite' => array("slug" => "work"), // Permalinks format

and did you use this permalink ?

/%category%/%postname%/

You will need to save permalinks again with above settings.

Update: I think John has a way better solution.

Hi Matt

This is doable, but not for faint hearted!

Firstly, you need to make sure your post type is declared correctly. If you doing that with a plugin, then this might be tricky. If you have code in functions.php then it's just a matter of changing the rewrite line to this:


'rewrite' => array( 'slug' => 'work/%taxonomy%', 'hierarchical' => true, 'with_front' => false )


Then you need to filter the permalink to create your custom version:


function filter_permalink( $permalink, $post, $leavename, $sample ) {
if( $post->post_type == 'work' ) {

if( $terms = get_the_terms($post->ID, 'YOUR_TAXONOMY_NAME') ) {
$dir = array();
$term = array_pop($terms);

$dir[] = $term->slug;

while( $term->parent != 0 ) {
$term = get_term( $term->parent, 'YOUR_TAXONOMY_NAME' );
$dir[] = $term->slug;
}

$dir = array_reverse( $dir );
$permalink = str_replace( '%taxonomy%', implode( '/', $dir ), $permalink );
}
}
return $permalink;
}
add_filter('post_type_link', 'filter_permalink', 10, 4);


And that will get you there. Please ask if you want me to explain the code.

This is a work Custom post type plugin, just copy and paste into a new file in plugins folders and activate.

Francisco Javier Carazo Gil answers:

Maybe you are doing it in the right way but not in the right order:

1. define custom post type
2. visit permalinks settings page (which flushes the rewrite rules) -- don't even need to change or re-save the permalink settings
3. go add posts with custom post type

If you flush your rules from the code, remember: Flush rules only on activation or deactivation. Don't do it on any other hook.
