i’m working on somekind of wiki/encyclopedia system based on wordpress.
there are two custom post types. i’ll show my configuration for one of them:
$labels = array(
'name' => _x('Objects', 'post type general name'),
'singular_name' => _x('Object', 'post type singular name'),
'add_new' => _x('Add New', 'object'),
'add_new_item' => __('Add New Object'),
'edit_item' => __('Edit Object'),
'new_item' => __('New Object'),
'view_item' => __('View Object'),
'search_items' => __('Search Objects'),
'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,
'has_archive' => 'objects', // this is the archive-slug (could be "objects/index"!!)
'rewrite' => array( 'slug' => 'objects' ), // this is the prepended slug (like "objects/my-object")
'capability_type' => 'post',
'hierarchical' => false,
'menu_position' => null,
'supports' => array('title','thumbnail')
);
register_post_type( 'dr_object' , $args );
everything is working as expected: mysite.de/objects gives me an overview (archive-dr_object.php template), mysite.de/objects/my-object shows the object details.
to have some nice urls for the frontend editing functions, i added rewrite endpoints.
add_rewrite_endpoint('do', EP_PERMALINK | EP_PAGES ); // for do/edit, do/remove, etc
this works great for urls like mysite.de/objects/my-object/do/edit
here comes my problem:
the archives should have some editing capabilities, too. but mysite.de/objects/do/edit gives me a 404: “Page not found”.
i print_r’ed $wp_query and it looks like wp queries an attachment named “edit”
hope somebody can help me – by now i’ll stick with ugly ?do=edit urls for the archives.
thanks in advance,
hans

add_action('init', dr_rewrite_settings);
as you can see – i had problem flushing the rewrite in a proper way (register_activation_hook).
apart form that i should mention that i’m using another plugin to create a fakepage: mysite.de/objects/new and it goes like this:

i made two modifications to the standard plugin. maybe they interfer with the rewrite_rules? (i tried deactivating this plugin – didn’t change a thing)
1) using a “hierarchical” slug. it works but: is it allowed?
2) let the fakepage use a custom template: add_post_meta($post->ID, '_wp_page_template', 'objects-new.php', true); (right before returning the post in createPost())
