Cannot use string offset as an array

Question

I am a trainee now. I am continue doing a a project left by last semester trainee. I found out he did a code as below :

 $auth = $this->Auth->User();
    if(!empty($auth)) {
        $auth['User']['is_admin'] = $this->inGroup('admin');

Can anyone teach me how to avoid this error ? Thank you.

He posted the error as the question title: "Cannot use string offset as an array" — sikander

Fatal error: Cannot use string offset as an array, the $auth is a string. Someone told me string cannot be used this way, and I don't know why the last trainee did like this. I just continue his project, and I am still figuring how it works. — Maki92

You can check if $auth is an array.

 if(!empty($auth) && is_array($auth) && isset($auth['User'])) {

Thanks for helping me, although I don't really understand, but the fatal error is now gone, it proceeded to next error " AclNode::node() - Couldn't find Aro node identified by "Array ( [Aro0.model] => User [Aro0.foreign_key] => 2 ) " "

the error indicates that you parse string into array expected function

eg.

$this->inGroup(array('admin')); //check out its function definition for valid parameters.
