问题描述
我以前使用的CakePHP，现在使用codeigniter，但遗憾的是并没有任何认证或ACL内置库..after更多搜索我已经找到一个好的图书馆，但我不知道如何使用它..它是没有例子使用it..any人不得不创建控制器和模型为样本...感谢帮助
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

* 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";
}

样品ACL班codeigniter
推荐答案
我是来自Tastybytes布赖恩。我最好的解决办法是步了code点火ACL库是基于教程。它是从基础的PHP文件CI图书馆100％的直口。
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.

和可能看网页的底部在哪里办理安装，什么不是。
And possibly look at the very bottom of the page where I go through "Installation" and what not.
