custom slug for custom post type

Question

hi and thanks for reading.

my issue is, i want to insert the specific author into my custom post type article. my code looks like this

register_post_type('charts', array( 'label' => 'Charts','description' => '','public' => true,'show_ui' => true,'show_in_menu' => true,'capability_type' => 'post','hierarchical' => false,'rewrite' => array('slug' => '/charts/author'),'query_var' => true,'supports' => array('title','editor','trackbacks','custom-fields','comments','author',),'labels' => array ( 
'name' => 'Charts',
'singular_name' => 'Charts',
'menu_name' => 'Charts',
'add_new' => 'Add Charts',
),) );

while i want 'rewrite' => array('slug' => '/charts/author') to show example.com/charts/%author%/...

any idea on how to realize this?

bless jnz

i found a solution and share it, cause its nice to be nice. hope this is all correct, otherwise feel free to correct me. this works for me and is based on a solution by Jonathan Brinley

first create your custom post type and set it up like this (this is just an example, remeber to make it fit for your own needs.. important is the setting for the slug)

register_post_type(
    'charts', 
    array(  
        'label' => 'Whatever',
        'description' => '',
        'public' => true,
        'show_ui' => true,
        'show_in_menu' => true,
        'capability_type' => 'post',
        'hierarchical' => true,
        'rewrite' => array('slug' => '/whatever/%author%'),
        'query_var' => true,
        'supports' => array(
            'title',
            'editor',
            'trackbacks',
            'custom-fields',
            'comments',
            'author'
        ) 
    ) 
);

then you need to set up a function for your filter (in functions.php)

function my_post_type_link_filter_function( $post_link, $id = 0, $leavename = FALSE ) {
   if ( strpos('%author%', $post_link) === FALSE ) {
      $post = &get_post($id);
      $author = get_userdata($post->post_author);
      return str_replace('%author%', $author->user_nicename, $post_link);
   }
}

and activate the filter (also in functions.php)

add_filter('post_type_link', 'my_post_type_link_filter_function', 1, 3);

like i said, i dont know, if this is all super correct, but it works for me :)
