[SOLVED] How do I check if a user has certain role and therefore allow some actions?

How do I check if a user has certain role and therefore allow some actions?

I need to check if logged in user has certain roles on the system so I allow or not some actions. I'm using JMSSecurityExtraBundle and I check the docs for Expression Based Authorization but I'm doing something wrong since code is not working. Take a look to this code:

use JMS\SecurityExtraBundle\Annotation\Secure;
use JMS\SecurityExtraBundle\Security\Authorization\Expression\Expression;

if ($this->get('security.context')->isGranted(array(new Expression('hasRole("ROLE_ADMIN")')))) {
    echo "Enter";
} else {
    echo "Do not enter";
}

But any time I logged in, even as ADMIN which have all the rights and has ROLE_ADMIN, the only text I'm seeing is "Do not enter" which is totally wrong. In the example code as explain in here the author use a $securityContext var but where it comes from? Where this var is defined? I assume that it will point to SecurityContext but I'm not so sure so, where is the problem on my code? How do I check if user has certain role and therefore allow it to execute some code or not?

Solution

You don't need any usage of annotation expressions if you just want to check user's roles in controller, this is sufficient:

if ($this->get('security.context')->isGranted('ROLE_ADMIN')) {
    echo "Enter";
} else {
    echo "Do not enter";
}

One quick search on google would have returned you documentation section about that right away: http://symfony.com/doc/current/book/security.html#access-control
