custom post type capabilities

I've just updated the plugin today, adding a "Custom" rule for capability type. With that, the plugin auto generate capabilities for the new post type like: edit_cpt, delete_cpt. Please try and let me know how it goes.

Just to confirm, adding 'map_meta_cap' => true, solves the problem. Doing so maps all of the primitive capabilities to the custom capability.

Hi Anh,

It works fine, but when you add a custom capability then that capability needs to be given to any roles who need it, including administrators.

This isn't the responsibility of Meta Box, it's up to the admin to provide the appropriate permissions to any roles that need it.

The only thing I'd suggest is that you might want to add some information to the documentation because many people won't know this otherwise.

I tried to set 'capability_type' => 'custom' in my custom post type, but I was not able to see the custom capabilities in my Roles and Capabilities plugin.

Then, I tried to keep the custom option and assigned the custom capabilities (that should be generated by the MB plugin) to the Administrator role by code, but I couldn't see the custom post type menu. Like this:

$role = get_role( 'administrator' );

$role->add_cap( 'edit_news_post',        true );
$role->add_cap( 'read_news_post',        true );
$role->add_cap( 'delete_news_post',      true );
$role->add_cap( 'edit_news',             true );
$role->add_cap( 'edit_others_news',      true );
$role->add_cap( 'publish_news',          true );
$role->add_cap( 'read_private_news',     true );
$role->add_cap( 'read',                  true );
$role->add_cap( 'delete_news',           true );
$role->add_cap( 'delete_private_news',   true );
$role->add_cap( 'delete_published_news', true );
$role->add_cap( 'delete_others_news',    true );
$role->add_cap( 'edit_private_news',     true );
$role->add_cap( 'edit_published_news',   true );
$role->add_cap( 'edit_news',             true );

Lastly, I tried to access the URL of the post type manually: /wp-admin/edit.php?post_type=news, but I got the following error message:

You need a higher level of permission.
Sorry, you are not allowed to edit posts in this post type.

Here's the code I used to create my custom post type:

function register_post_type__news()
{
    $labels = [
        'name'                     => esc_html('News'),

    $args = [

        'labels'              => $labels,
        'description'         => 'The main post type that is used to create and publish news articles.',

    register_post_type( 'news', $args );
}

Could you please advise me?
