if I have the current user object, how can i get a list of all of the permissions he has in drupal 8 custom module ? I dont want to check for one particular permission which would be $current_user->hasPermission("permission_name").

I want to get the entire list of his permissions.

thanks

Can you try the following snippet:

$user = \Drupal::currentUser();
$user_roles = $user->getRoles();
$roles_permissions = user_role_permissions($user_roles);

This will give you permissions grouped by roles. But most likely you want them in one array.

Therefore you can use this

$final_array = array();
foreach ($roles_permissions as $role_key => $permissions) {
  foreach ($permissions as $permission) {
    $final_array[] = $permission;
  }
}

In case you want to load different user than the currently logged-in user, you can use

$some_user = \Drupal\user\Entity\User::load(123);

Where 123 stands for the user id. For more information:

  • This will get the current logged in user, not any user. But, in theory the script/snippet could be modified to load a specific user by their id and then view the role permissions they have. – tenken Mar 13 '17 at 14:27
  • Yes @tenken, you are correct. I saw in the question $current_user, so I assumed we are talking about the currently logged in user. #TODO, add a script for loading different user. – O V Mar 13 '17 at 14:30
