Question

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 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
