Symfony 2 - Accessing Hierarchical Roles in a twig template

Question

In my template, I need to know if a user has certain role to display things according to it. So far, I've implemented a little function in my user class:

  public function hasRole($role) {
    $roles = array();
    foreach ($this->getRoles() as $rol) {
      $roles[] = $rol->getRole();
    }
    return in_array($role, $roles);
  }

which tells me if this user has the role specified by the string passed as a parameter. This work and can be called from a twig template, but doesn't allow me to know anything about the roles hierarchy. Is there a way to access the role hierarchy from a controller? and directly from a twig template? I've looked through the official docs and didn't find anything about.

You can check the roles in twig templete by using below code,It explains that if the current user has the below role,then show something

{% if is_granted('ROLE_ADMIN') %}

  //show things related to admin role

{%else if is_granted('ROLE_USER')%}
//show things related to user role
{% endif %}

Hope this helps you. Happy Coding!!

Thanks for your answer! One question: What if my user has the `ROLE_SUPERADMIN` which is hierarchically greater than `ROLE_ADMIN`? does `{% if is_granted('ROLE_ADMIN') %}` evaluate `true`? – Throoze Apr 22 '12 at 04:50

Throoze@: if a user logged in with ROLE_SUPERADMIN ,he is hierarchically greater than ROLE_ADMIN(hope hierarchical order you specified in secutiy.yml),then it will evaluate true,because hierarchically he is a user with both ROLE_SUPERADMIN and ROLE_ADMIN so it becomes True – Asish AP Apr 22 '12 at 07:37
sorry for bothering you... which is the equivalent to `is_granted()` in a controller? – Throoze Apr 22 '12 at 13:06

Throoze@: in controller you can check the users in role wise as below code if(TRUE === $this->get('security.context')->isGranted('ROLE_SUPERADMIN')){//superADMIN} else if(TRUE === $this->get('security.context')->isGranted('ROLE_ADMIN')){//ADMIN} – Asish AP Apr 23 '12 at 04:07
