The Objective: Create a custom post type and only give administrator and a custom role permission to view / control it.
The Problem:
For administrators, it works perfectly fine but for the custom role I get:
Sorry, you are not allowed to access this page.
At first, I thought it could just be a matter of capability to access it, but this bit of code begs to differ:
add_submenu_page( /* STAFF PAGES */
'redacted', //Parent Menu Slug
'Staff Pages', //Page Title text
'Staff Pages', //Menu Title text
'edit_staff', //Capability required for this menu to be displayed by user
'edit.php?post_type=staff' //Link to page
);
The custom role can see the link to the custom post type but cannot access it. Also, running print_r($wp_roles->get_role( 'supervisor' )->capabilities); does show that the role correctly possesses the necessary capabilities. I've had a few theories as to how to solve this, but so far none have panned out.
My code is as follows:
function initialize_plugin(){
//Non-relevant code redacted
add_action( 'admin_init', array($this, 'admin_init') );
}
function activate(){
$this->custom_post_types();
$this->adjust_user_roles();
//Non-relevant code redacted
}
/* My Custom Post Type */
function custom_post_types(){
register_post_type( 'staff', array(
'labels' => array(
//labels redacted
),
'has_archive' => false,
'hierarchical' => true,
'menu_icon' => 'dashicons-groups',
'capability_type' => array('staff', 'staffs'),
'map_meta_cap' => true,
'public' => true,
'show_in_menu' => false,
'rewrite' => array( 'slug' => 'staff', 'with_front' => false ),
'supports' => array( 'title', 'thumbnail', 'custom-fields', 'revisions'),
'show_in_rest' => true,
'taxonomies' => array( 'member-type' ),
'menu_position' => 2,
));
/* My Custom Role */
function adjust_user_roles(){
$wp_roles = new WP_Roles();
$wp_roles->add_role(
'supervisor', __( 'Supervisor' ),
array(
//General
'moderate_comments' => true,
'upload_files' => true,
//Blog Posts
'read' => true,
'read_post' => true,
'edit_post' => true,
'edit_posts' => true,
'edit_others_posts' => true,
'delete_posts' => false, //Can't delete posts
//Staff (Custom Post Type)
'create_staffs' => true,
'read_staff' => true,
'edit_staff' => true,
'edit_staffs' => true,
'edit_others_staffs' => true,
'edit_published_staffs' => true,
'edit_private_staffs' => true,
'delete_staff' => true,
'delete_others_staffs' => true,
'delete_published_staffs' => true,
'delete_private_staffs' => true,
'publish_staffs' => true,
'read_private_staffs' => true,
)
);
/* Adding to administrator */
function admin_init(){
//Non-relevant code redacted
$this->adjust_user_capabilities("add");
}
function adjust_user_capabilities($action, $roles=array('administrator','editor', 'supervisor')){
$staffCaps = array(
'create_staff',
'read_staff',
'edit_staff',
'edit_staffs',
'edit_others_staffs',
'edit_published_staffs',
'edit_private_staffs',
'delete_staff',
'delete_others_staffs',
'delete_published_staffs',
'delete_private_staffs',
'publish_staffs',
'read_private_staffs',
);
//Cycle through each role
foreach($roles as $roleType) :
$role = get_role( $roleType );
//Add each capability
if($action == "add"){
foreach($staffCaps as $staffCap){
$role->add_cap( $staffCap );
}
}
//Remove each capability
elseif($action == "remove"){
foreach($staffCaps as $staffCap){
$role->remove_cap( $staffCap );
}
}
endforeach;
}
NOTE:
This code appears in wp-content/plugins/myplugin/myplugin.php. In addition, I have redacted some non-relevant portions of my code for clarity, such as adding or removing a submenu, and tried to expound more of the structure. Feel free to let me know if there is anything I missed or anyone has questions on. :-D
In Closing: I could just be a major idiot overlooking something obvious, but regardless, any and all help / advice / suggestions are highly appreciated! If I get the answer on my own, I'll add it to this discussion to help anyone else out facing a similar problem and/or my future self lol
