The method of Yii permission control (three kinds of methods) _php instance

This article illustrates the method of Yii permission control. Share to everyone for your reference, specific as follows:

Here are excerpts of the following 3:

1. Through AccessControl:

Public function Filters ()
{return
  array (
    ' AccessControl ',//Perform access control for CRUD operations
  );
}
/**
 * Specifies the access control rules.
 * This are used by the ' AccessControl ' filter.
 * @return Array access control rules/public
function accessrules ()
{return
  array (
    ' Allow ',//Allow authenticated users to access all actions
      ' users ' =>array (' @ '),
    Array (' Deny ',// Deny all users '
      users ' =>array (' * '),)
  ;
}

2. Through the plugin (such as: right)

Public function Filters ()
{return
  array (
    ' rights ',
  );
}

3. Blending mode:

/**
 * @return Array Action Filters
 *
/Public Function filters ()
{return
  array (
    ' Updateown + Update ',//Apply This filter to the update action.
    ' Rights ',
  );
}
/**
 * Filter to checking whether the currently logged in user * is the author of the
 post being accessed .
 * * Public
function Filterupdateown ($filterChain)
{
  $post = $this->loadmodel ();
  Remove the ' Rights ' filter if the user is updating a own post/and has the permission to does so
  .
  if (Yii::app ()->user->checkaccess (' Postupdateown ', Array (' userid ' => $post->author_id))
    $ Filterchain->removeat (1);
  $filterChain->run ();
}

If you have permission to open certain actions on the basis of permission, you can pass allowedactions:

Public Function allowedactions ()
{return
  ' Autocomplate,autocomplate2 ';
}

I hope this article will help you with the PHP program design based on the YII framework.
