How to get list of all users?

Question

As in title, how can I get a list of all users in Magento ? Found already some examples but none of those works. All I managed to get was either only one user (myself) or nothing while I was expecting at least 3! Using this code as a result I'm getting ONE

$users = Mage::getModel('admin/user');

$usersCollection = $users->getCollection()->load();

foreach($usersCollection as $user){
    echo 'User: ' . $user->getFirstname() . '<br/>';
    echo 'User: ' . $user->getLastname() . '<br/>';
    echo 'User: ' . $user->getName() . '<br/>';
}

What am I doing wrong ?

Answer 1

To get all the Roles

$roles = Mage::getModel('admin/roles')->getCollection();
   foreach($roles as $role):
      echo '<br/>Role : '.$role->getId()." | ".$role->getRoleName();
   endforeach;

To get the Role users

$roles_users = Mage::getResourceModel('admin/roles_user_collection');
  foreach($roles_users as $roleuser):
   $user = Mage::getModel('admin/user')->load($roleuser->getUserId());
   echo '<br/>User : '.$user->getUsername()." | ".$user->getFirstname();
  endforeach;

Please print the collection and then check data as same code worked for me.

$adminUser = Mage::getModel('admin/user');
$collection = $adminUser->getCollection()->load(); 
print_r($collection->getData());
