Do you want to display the custom post type as a submenu within the post edit menu? While there’s probably a plugin for this, we have created a quick code snippet that you can use display custom post type menu as submenu in WordPress.
Instructions:
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
function nacin_register_slideshows_post_type() {
register_post_type( 'slideshow', array(
'labels' => array(
'name' => 'Slideshows',
'singular_name' => 'Slideshow',
),
'public' => true,
'show_ui' => true,
'show_in_menu' => 'edit.php',
'supports' => array( 'title' ,'thumbnail', 'editor' ),
) );
}
add_action( 'init', 'nacin_register_slideshows_post_type' );

i register post_type with add new item, but ‘add new item’ not show in submenu, any suggestion for my problem ?
Nice. Trying to take this a step further and attach the post type to a custom menu page. So far no cigar… any thoughts?
Your question is old but figured this might come in handy for someone else.
I just spent a long time looking through the WP source code trying to do the
same thing: I have a custom menu created using add_menu_page(). It has a handful
of sub_menu items. I have a custom post type that is related to this menu and I
wanted the add / list links for that post type to be submenu items.
Short answer: No easy way to do it in WP. The way it
generates the menus and custom post type UI means there is no simple call you
can make.
Solution:
1. Register your post type with the
following options:
‘show_ui’ => true,
‘show_in_menu’ => false
In
this example my custom post type is acct_notes
2. In your theme’s functions.php file or your plugin file, add an action to
admin_menu:
add_action(‘admin_menu’,
‘modify_admin_menus’);
3. Add submenu_pages for the two post UI links — list posts, create new
post.
The first param is the slug of the menu you’re adding it to. The second
is the name that will show up on the page. The third is what the link will show
up as. The fourth is the capability required to access it. The fifth is the slug
for this menu item. And last is the function that will generate the output. In
this case we’re not going to use it so we can pass NULL.
add_submenu_page(‘members’, ‘Account Notes’, ‘Account Notes’,
‘manage-options’, ‘view_account_notes’, NULL);
4. The last step is the function that will change those submenu links so
that they go to the correct post UI pages.
function modify_admin_menus(){
global $submenu;
if(array_key_exists(‘members’, $submenu)){
foreach($submenu[‘members’] as $key => $value){
$k =
array_search(‘view_account_notes’, $value);
if($k){
$submenu[‘members’][$key][$k] =
(current_user_can($submenu[‘members’][$key][1]))?
admin_url(‘/edit.php?post_type=acct_notes’):”;
}
$l = array_search(‘new_account_note’, $value);
if($l){
$submenu[‘members’][$key][$l] =
(current_user_can($submenu[‘members’][$key][1]))?
admin_url(‘/post-new.php?post_type=dojo_acct_notes’) : ”;}
}
}
}
What’s going on in the function is that it’s checking the global $submenu
array to see if our top level menu item (members) exists — it might not if the
user doesn’t have permission to access it. If they do it then looks to see if
that top level menu item has a submenu page with the slug “view_account_notes”
— what we assigned in add submenu_page. Finally, it checks the permission we
assigned in add_submenu_page and if the current user has that permission it
outputs the new link. If they don’t it removes the link altogether.
We do that same check twice — once for the link to list our custom post
type, and once for the link to add a new custom post type.
It would be far preferable to have this capability built in, but this will
let you add custom post type user interfaces to any menu you want.
Thank you very much. Can you help me, please? I am having problem: I want create a menu in WordPress admin contained many child custom post type to easy to manage. Example:
Menu Facilities include post types: – Meetings; – Weddings; – SPA
