问题:

i used cakephp before and now use codeigniter but Unfortunately hasn't any authentication or ACL built-in library ..after more search i have found a good library, but I do not know how to use it..it is no example to use it..any one have create controller and model as sample...thanks for helping

<?php

class acl {
    /* Actions::::
     * Create 1
     * Read 2
     * Update 4
     * Delete 8
     * The allowance is made by a sum of the actions allowed.
     * Ex.: user can read and update (2+4)=6 … so ill put 6 instead of 1 or 0.
     *
     * if(!$this->acl->hasPermission(‘entries_complete_access')) {
      echo “No no”;
      } else
     * echo “yeah”;
      }

}

and this is the url sample ACL Class for codeigniter

回答1:

This is simple

Load it first in your controller

$this->load->library('acl');

Now call its method

$this->acl->buildACL();

EDIT Use these for menuall assigning 

$this->acl->perms = array('your values');
$this->acl->userID= 'user id';
$this->acl->userRoles = array('your values');

Note that you should have db table userRoles which will be invoked when the library is initialized getUserRoles method will be called and $userRoles parameter will have values.



回答2:

I'm Brian from Tastybytes. My best solution would be to step through the tutorial that the code igniter ACL library is based on. It is a 100% straight port from the base php files to CI Library.

http://net.tutsplus.com/tutorials/php/a-better-login-system/

And possibly look at the very bottom of the page where I go through "Installation" and what not.
