You have to use an instance variable not a local. Instead of

$checkLogin

use

$this->checkLogin

in both controllers and it will work.

Example:

class AbstractUser{
    function __construct(){
        $this->instanceVar = true;
        $localVar = true;
    }
}


class User extends AbstractUser{
    function __construct(){
        parent::__construct();
    }

    function useVariables(){
        var_dump(isset($this->instanceVar));  # returns true
        var_dump(isset($localVar));           # returns false
    }
}

$user = new User;

$user->useVariables();

EDIT

Updated the example to resemble more your use case.

You cannot access checkLogin unless you make it a global variable.Check variable scope in PHP.
