如何将变量从preDispatch传递给控制器​​和动作？

Question

I try to put a variable in preDispatch function that check login, and I want to pass this variable to controllers (for Action to use).

I just try $this->getRequest()->setParam('check_login', 'FALSE');

But it doesn't work ...

Do anyone know how to do that?

Answer 1

if you have no particular reason to pass the variable in the request object assign that variable to a private or protected member:

<?php
class my_Controller extends blah blah
{
    protected $login; 

    public function preDispatch()
    {
        $this->login = what it needs to be
    }
}

However the code you present works for me. Except for one small item. If you wish to use 'FALSE' as a boolean you may need to remove the quotes. The way it is presented at the moment 'FALSE' is a string and may not work properly as a boolean operator.

$this->getRequest()->setParam('check_login', FALSE);
