检查会话用户是管理员还是简单用户

Question

i want to make if clause for button. If admin is logged in it will shown otherwise not.

if($this->Session->User['role'] == 'admin') {
    echo
    '<li> <a href="/VAG/dashboard"><ul class="pull-right">Admin skiltis</ul></a></li>';
}

I can't get that role from session and compare if it admin or not..

Answer 1

Using $_SESSION['Auth']['User'] directly is a bad practice, as depending how the AuthComponent is configured, it may not be available.

You should better pass the authenticated user from the controller to the views and then only check his properties:

AppController:

$authenticated_user = $this->Auth->user();

if(isset($authenticated_user))
{
    $this->set(compact('authenticated_user'));
}

Views:

if(isset($authenticated_user) && $authenticated_user['role'] == 'admin'){
    ...
}

By the way you should also use the HtmlHelper in your views to generate links instead of printing <a> tags manually with hardcoded urls to benefit from many Cake features.

Answer 2

Try to make a little debug on your code.

First check if your session was started. You can do this by executing the command "session_status()" if the result is "PHP_SESSION_NONE" your session isnt started. You can fix it by putting a "session_start()" before any print was made by your page.

Answer 3

If value of print_r($_SESSION); is something like,

Array ( [Config] => Array ( [userAgent] => 4df452d8263aa05ef9324f37499322b0 [time] => 1401090120 [countdown] => 10 ) [Message] => Array ( ) [Auth] => Array ( [User] => Array ( [id] => 8 [username] => aaaaa [email] => aaa@gmail.com [role] => admin [created] => 2014-05-26 02:43:20 [modified] => 2014-05-26 02:43:20 [status] => 1 ) ) )

Thae try this code, I think it will work,

if($_SESSION['Auth']['User']['role'] == 'admin') {
echo
'<li> <a href="/VAG/dashboard"><ul class="pull-right">Admin skiltis</ul></a></li>';
}
