Trying to get new role to have edit permissions for custom content type

Question

I've used several tutorials and tried to apply various "solutions", but I'm still unable to get a custom role to edit their own posts for a custom type.

I created the role, which shows fine...

function mymodule_create_role() {
  add_role( 'resident', 'New Role', array(

    'read' => true, // True allows that capability
    'create_posts' => false,
    'edit_posts' => false, // Allows user to edit their own posts
    'publish_posts'=>false, //Allows the user to publish, otherwise posts stays in draft mode
    'edit_published_posts'=>false,
    'upload_files'=>true,
    'delete_published_posts'=>false,
  ));
}

I've also registered my new content type, which seems fine...

function register_bulletin_board() {
  $labels = array( 
    'name' => _x( 'Bulletin Board', 'bulletin_board' ),
    'singular_name' => _x( 'Bulletin Board', 'bulletin_board' ),
    'add_new' => _x( 'Add New', 'bulletin_board' ),
    'add_new_item' => _x( 'Add New Bulletin Board', 'bulletin_board' ),
    'edit_item' => _x( 'Edit Bulletin Board', 'bulletin_board' ),
    'new_item' => _x( 'New Bulletin Board', 'bulletin_board' ),
    'view_item' => _x( 'View Bulletin Board', 'bulletin_board' ),
    'search_items' => _x( 'Search Bulletin Board', 'bulletin_board' ),
    'not_found' => _x( 'No bulletin board found', 'bulletin_board' ),
    'not_found_in_trash' => _x( 'No bulletin board found in Trash', 'bulletin_board' ),
    'parent_item_colon' => _x( 'Parent Bulletin Board:', 'bulletin_board' ),
    'menu_name' => _x( 'Bulletin Board', 'bulletin_board' ),
  );

  $args = array( 
   'labels' => $labels,
   'hierarchical' => true,
   'description' => 'Bulletin board for citizen posts',
   'supports' => array( 'title', 'editor','author'),
   'public' => true,
   'show_ui' => true,
   'show_in_menu' => true,
   'menu_icon' => get_bloginfo('template_url') . '/images/imagegallery.png',
   'show_in_nav_menus' => true,
   'publicly_queryable' => true,
   'exclude_from_search' => false,
   'has_archive' => true,
   'query_var' => true,
   'can_export' => true,
   'rewrite' => true,
   'capabilities' => array(
     'edit_post' => 'edit_bulletin_board',
     'edit_posts' => 'edit_bulletin_boards',
     'edit_others_posts' => 'edit_other_bulletin_board',
     'publish_posts' => 'publish_bulletin_board',
     'read_post' => 'read_bulletin_board',
     'read_private_posts' => 'read_private_bulletin_board',
     'delete_post' => 'delete_bulletin_board'
    ),

    'map_meta_cap' => true
  );

  register_post_type( 'bulletin_board', $args );
}

And finally, I've applied the add_cap to my roles, which includes my new "resident" role...

$roles = array('administrator','resident','editor');

// Loop through each role and assign capabilities
foreach($roles as $the_role) { 

  $admins = get_role( $the_role );
  $admins->add_cap( 'can_edit_posts' );
  $admins->add_cap( 'edit_bulletin_board' ); 
  $admins->add_cap( 'edit_bulletin_boards' ); 
  $admins->add_cap( 'edit_other_bulletin_board' ); 
  $admins->add_cap( 'publish_bulletin_board' ); 
  $admins->add_cap( 'read_bulletin_board' ); 
  $admins->add_cap( 'read_private_bulletin_board' ); 
  $admins->add_cap( 'delete_bulletin_board' ); 
}

Now, when I login as a "resident", I can post a Bulletin Board post, but this user has no ability to edit or delete. From what I've read, the capabilities should be tied via add_cap() to the capabilities array used with register_post_type(), which seems to be the case.

I've also installed the User Role Editor plugin and I see the checks for editing of the bulletin board, but that still doesn't seem to mean anything.

Any suggestions would be very appreciated.

Answer 1

Not an answer to the question, but a workaround.

I found that using the Custom Post Type UI plugin to create the custom datatype would offer new capabilities, as long as I changed the Capability Type field.

Using the User Role Editor plugin seems to allow me to bridge the permissions with a custom user role.

Answer 2

when you fixe capabilities on the custom type registration, it gives a strange mix of capabilities. Look the result with this code :

echo "<pre>";
var_dump(get_post_type_object('bulletin_board')->cap);

I recommand to use "capability_type" like that :

$args = array(
    'labels' => $labels,
    'hierarchical' => true,
    'description' => 'Bulletin board for citizen posts',
    'supports' => array(
        'title',
        'editor',
        'author'
    ),
    'public' => true,
    'show_ui' => true,
    'show_in_menu' => true,
    'menu_icon' => get_bloginfo('template_url') . '/images/imagegallery.png',
    'show_in_nav_menus' => true,
    'publicly_queryable' => true,
    'exclude_from_search' => false,
    'has_archive' => true,
    'query_var' => true,
    'can_export' => true,
    'rewrite' => true,

    'capability_type' => "bulletin_board",
    'map_meta_cap' => TRUE,
);
