The way we achieve this setup of using controller and action names to dictate permissions is to write a plug-in for Zend_Controller (by extending the Zend_Controller_Plugin_ Abstract class). This plug-in defines the preDispatch() method, which receives a user request before the front controller dispatches the request to the respective action. Effectively, we are intercepting the request and checking whether the current user has sufficient privileges to execute that action. To register a plug-in with Zend_Controller, we call the registerPlugin() method on our Zend_Controller_Front instance. Before we do that, let s create the plug-in, which we will call CustomControllerAclManager. We will create all roles and resources for Zend_Acl in this class, as well as checking permissions. Listing 3-5 shows the contents of the CustomControllerAclManager.php file, which we will store in the /var/www/phpweb20/include directory. Listing 3-5. The CustomControllerAclManager Plug-in, Which Checks Permissions Prior to Dispatching User Requests (CustomControllerAclManager.php) < php class CustomControllerAclManager extends Zend_Controller_Plugin_Abstract { // default user role if not logged or (or invalid role found) private $_defaultRole = 'guest'; // the action to dispatch if a user doesn't have sufficient privileges private $_authController = array('controller' => 'account', 'action' => 'login'); public function __construct(Zend_Auth $auth) { $this->auth = $auth; $this->acl = new Zend_Acl(); // add the different user roles $this->acl->addRole(new Zend_Acl_Role($this->_defaultRole)); $this->acl->addRole(new Zend_Acl_Role('member')); $this->acl->addRole(new Zend_Acl_Role('administrator'), 'member'); // add the resources we want to have control over $this->acl->add(new Zend_Acl_Resource('account')); $this->acl->add(new Zend_Acl_Resource('admin')); // allow access to everything for all users by default // except for the account management and administration areas $this->acl->allow(); $this->acl->deny(null, 'account'); $this->acl->deny(null, 'admin'); // add an exception so guests can log in or register // in order to gain privilege c# pdf library: Download / Display PDF file in browser using C# in ASP.Net MVC ... pdfsharp table example c# How to read and create barcode images using C# and ZXing .NET ...

An useful C# code snippet to convert PDF files into TXT plain- text or HTML in C# with iTextSharp , an open-source PDF management library for ... $request->setActionName($this->_authController['action']); } } } > The class constructor is where we define roles, resources, and permissions. In Listing 3-5 we first make the administrator role inherit from the member role. This means that any permission given to members is also given to administrators. Additionally, we can then give the administrator role privileges on its own to access the admin area. Next, we set up the default permissions (that is, permissions that apply to all roles). These allow access to everything except for the account and admin resources. Obviously, a guest needs the chance to authenticate themselves and become a privileged user, so we must open up access to the login and fetchpassword privileges. Additionally, if they are not yet registered, we need to grant them access to register and registercomplete (a helper action used to confirm registration to a user). Once a guest becomes authenticated (thereby becoming either a member or an administrator), they need to be able to access the account resource. Since the administrator role inherits from the member role, permitting members access to the account resource also gives access to administrators. Finally, we open up the admin areas to administrators only. In other words, guests and members cannot access this area. Now, let s take a look at the preDispatch() method, which takes the user request as an argument. First, we set up the role and resource so the ACL check will work correctly. If the resource is not found, we set the $resource variable to null, which means the default permission will be used for the given role. Based on the way we have set this up (that is, allowing access to everything), this effectively means the ACL check will return true. If the role is not found, we use the guest role instead.
