How to setup Module Specific ACL Resource?

Zend's Acl allows the resource to be created in controller only

But, the controllers might be on any module not just only the default module. So, I read some article off the internet, I found one and tried this:

$acl -> addResource(new Zend_Acl_Resource("admin"));
$acl -> addResource(new Zend_Acl_Resource("admin:page"), "admin");
$acl -> addResource(new Zend_Acl_Resource("admin:posts"), "admin");

But, still, when i browse to 开发者_如何学编程the respective pages, I get errors regarding resouce page not found, or posts not found.

How to setup Module Specific ACL Resource?

Update:

$acl -> addrole(new Zend_Acl_Role('guest'))
    -> addrole(new Zend_Acl_ROle('admin'), 'admin');

$acl -> addResource(new Zend_Acl_Resource("page")); //controller with same name in admin module exists

$acl -> addResource(new Zend_Acl_Resource("admin"));
$acl -> addResource(new Zend_Acl_Resource("admin:page"), "admin");
$acl -> addResource(new Zend_Acl_Resource("admin:posts"), "admin");

$acl -> deny(null, null);
$acl -> allow('user', 'page', 'view');
$acl -> allow('admin', null);

I'm guessing the code you posted was some sort of pseudo code, as it wasn't valid. Still, this answer should work perfectly fine as is.

$acl->addrole(new Zend_Acl_Role('guest'))
    ->addrole(new Zend_Acl_Role('admin'), 'guest');

$acl->addResource(new Zend_Acl_Resource("page"));
$acl->addResource(new Zend_Acl_Resource("admin"));
$acl->addResource(new Zend_Acl_Resource("admin:page"), "admin");
$acl->addResource(new Zend_Acl_Resource("admin:posts"), "admin");

$acl->deny();
$acl->allow('guest', 'page', 'view');
$acl->allow('admin');

// Lets run some quick tests...
var_dump($acl->isAllowed('guest', 'page', 'view')); // true
var_dump($acl->isAllowed('guest', 'page', 'edit')); // false
var_dump($acl->isAllowed('guest', 'admin:page', 'view')); // false

var_dump($acl->isAllowed('admin', 'page', 'view')); // true
var_dump($acl->isAllowed('admin', 'page', 'edit')); // false
var_dump($acl->isAllowed('admin', 'admin:page', 'view')); // true
