title: Laravel 5.1 form::radio, cant get "false" from variable but when I type false it works
body: <p>this is my code</p>
  
  <pre><code>&lt;div class="form-group"&gt;
  {!! Form::label('', '*Role') !!}
  @foreach ($roles as $role)
      &lt;div class="radio"&gt;
          {!! Form::radio( 'role', $role-&gt;id, $user-&gt;getRolesCheckedAtrribute($user, $role), ['id' =&gt; $role-&gt;slug]) !!}
          {!! Form::label($role-&gt;slug, $role-&gt;name) !!}
          {!! $user-&gt;getRolesCheckedAtrribute($user, $role) !!}
      &lt;/div&gt;
  @endforeach
  </code></pre>
  
  <p></p>
  
  <p>And the output is:</p>
  
  <pre><code>&lt;div class="form-group"&gt;
  &lt;label for=""&gt;*Role&lt;/label&gt;
          &lt;div class="radio"&gt;
                      &lt;input id="super-admin" checked="checked" name="role" value="1" type="radio"&gt;
          &lt;label for="super-admin"&gt;Super Admin&lt;/label&gt;
          false
      &lt;/div&gt;
          &lt;div class="radio"&gt;
                      &lt;input id="admin" checked="checked" name="role" value="2" type="radio"&gt;
          &lt;label for="admin"&gt;Admin&lt;/label&gt;
          true
      &lt;/div&gt;
          &lt;div class="radio"&gt;
                      &lt;input id="basic-user" checked="checked" name="role" value="3" type="radio"&gt;
          &lt;label for="basic-user"&gt;Basic User&lt;/label&gt;
          false
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The problem is that I cant get the value of <code>$user-&gt;getRolesCheckedAtrribute() inside of Form::radio</code>, but outside of it it echoes as it should. So every radio gets <code>checked="checked"</code> although only the second one has true.</p>
  
  <p>If I replace "$user->getRolesCheckedAtrribute($user, $role)" in Form::radio() with "false", then none of the buttons get checked.</p>
  
  <p>I'm using <code>Laravel 5.1</code> and require:        </p>
  
  <pre><code>  "kodeine/laravel-acl": "~1.0@dev",
    "laravelcollective/html": "^5.1"
  </code></pre>
  
  <p>If you need more details please ask.</p>
  
  <p>UPDATE:</p>
  
  <pre><code> public function getRolesCheckedAtrribute($user, $role) {
      if (head($user-&gt;getRoles()) == $role-&gt;slug) {
          $checked = 'true';
      }
      else {
          $checked = 'false';
      }
      return $checked;
  }
  </code></pre>
