Goal

This module is designed provide a facade for Zend\Acl that will ease its usage with modules and applications. By default, it provides simple setup via config files or by using Zend\Db. This module also comes with out-of-the-box support for and integration with ZfcUser.

Usage and Configuration

Here is an annotated sample configuration file:

create this file in config/autoload/BjyAuthorize.global.php

<?php

return array(
    'bjyauthorize' => array(

        // set the 'guest' role as default (must be defined in a role provider)
        'default_role' => 'guest',

        /* this module uses a meta-role that inherits from any roles that should
         * be applied to the active user. the identity provider tells us which
         * roles the "identity role" should inherit from.
         *
         * for ZfcUser, this will be your default identity provider
         */
        'identity_provider' => 'BjyAuthorize\Provider\Identity\ZfcUserZendDb',

        /* role providers simply provide a list of roles that should be inserted
         * into the Zend\Acl instance. the module comes with two providers, one
         * to specify roles in a config file and one to load roles using a
         * Zend\Db adapter.
         */
        'role_providers' => array(

            /* here, 'guest' and 'user are defined as top-level roles, with

);

Helpers and Plugins

There are view helpers and controller plugins registered for this module. In either a controller or a view script, you can call $this->isAllowed($resource[, $privilege]), which will query the ACL using the currently authenticated (or default) user's roles.
