Allow to see and edit in admin only assigned posts

To allow users to only be able to edit their own “companies”, remove the edit_other_companies capability from the role. That should keep them from editing other user’s companies.

To keep them from creating new companies, you’d have to set the create_posts capability up when registering your post type capabilities. You’d set it to something like create_companies but only give that to administrators.

As for actually hiding the companies that a user cannot edit, that would take a custom-built plugin. It’s not hard to build. Shoot me an email if you’re interested in talking it over.

Thanks for quick reply. I was using Custom Post Type UI plugin for creating custom post type, but it does not offer to customize capabilities. Then I have registered it manualy:
add_action(‘init’, ‘register_company_post_type_function’);
function register_company_post_type_function() {
$labels = array(
‘name’ => __(‘Companies’, ”),
‘singular_name’ => __(‘Company’, ”),
);
$args = array(
‘label’ => __(‘Companies’, ”),
‘labels’ => $labels,
‘description’ => ”,
‘public’ => true,
‘publicly_queryable’ => true,
‘show_ui’ => true,
‘show_in_rest’ => false,
‘rest_base’ => ”,
‘has_archive’ => ‘imones’,
‘show_in_menu’ => true,
‘exclude_from_search’ => false,
‘hierarchical’ => false,
‘rewrite’ => array( ‘slug’ => ‘imone’, ‘with_front’ => true ),
‘query_var’ => true,
‘supports’ => array( ‘title’, ‘editor’, ‘thumbnail’, ‘excerpt’, ‘author’ ),
‘taxonomies’ => array( ‘heading_category’, ‘company_category’, ‘company_country’ ),
‘capability_type’ => ‘company’,
‘capabilities’ => array(
‘edit_post’ => ‘edit_company’,
‘edit_posts’ => ‘edit_companys’,
‘edit_published_post’ => ‘edit_published_company’,
‘edit_published_posts’ => ‘edit_published_companys’,
‘edit_other_post’ => ‘edit_published_company’,
‘edit_other_posts’ => ‘edit_published_companys’,
‘edit_private_post’ => ‘edit_private_company’,
‘edit_private_posts’ => ‘edit_private_companys’,
‘create_post’ => ‘create_company’,
‘create_posts’ => ‘create_companys’,
‘publish_post’ => ‘publish_company’,
‘publish_posts’ => ‘publish_companys’,
‘copy_post’ => ‘copy_company’,
‘copy_posts’ => ‘copy_companys’,
‘delete_post’ => ‘delete_company’,
‘delete_posts’ => ‘delete_companys’,
‘delete_published_post’ => ‘delete_published_company’,
‘delete_published_posts’ => ‘delete_published_companys’,
‘delete_other_post’ => ‘delete_other_company’,
‘delete_other_posts’ => ‘delete_other_companys’,
‘delete_private_post’ => ‘delete_private_company’,
‘delete_private_posts’ => ‘delete_private_companys’,
),
‘map_meta_cap’ => true,
);
register_post_type(‘company’, $args);
}

Using Members plugin I’ve created role Manager and granted following capabilities for Companies:
edit_company
edit_companies
edit_published_company
edit_published_companies
publish_company
publish_companies

For Administrator I’ve granted all.

After doing this, logged in as Manager I could see Companies on admin menu, but still could not access edit.php?post_type=company page. Only after I granted edit_posts capability to Members I could access this page, but at the same time Manager got access to Posts and Tools admin menu. How can I hide these from Managers – they should see only Companies and Profile.

@eduardasm I am having exactly the same problem. Did you manage to find a solution?

Cheers,
