Question

我已经设置了一个用户组权限角色系统，用户可以拥有或不访问控制器或修改它们。

问题：如果我保留所有权限，则修改某个特定用户组的数组未选中。如果该用户组试图修改控制器它会抛出两个错误。取消选中修改权限时。

即使取消选中权限，我怎样才能使它能够正常工作。如果拥有该用户组的用户尝试修改它。它不会抛出这两个错误。

错误一

A PHP Error was encountered
Severity: Notice
Message: Undefined index: modify
Filename: libraries/User.php
Line Number: 206

错误二

A PHP Error was encountered
Severity: Warning
Message: in_array() expects parameter 2 to be array, null given
Filename: libraries/User.php
Line Number: 206

用户库功能

public function hasPermissionModify() {
      $user_id = $this->CI->session->userdata('user_id');
      $segment = $this->CI->uri->segment_array();                
      $permission = isset($segment[2]) ? $segment[2] : '';  

      $ignore = array(
         'blank',
         'error',
         'register',
         'dashboard',
         'column_left',
         'menu',
         'startup',
         'login',
         'logout',
         'forgotten',
         'reset',
         'not_found',
         'permission',
         'footer',
         'header'
      );

      if (isset($permission) && $permission && $user_id) { 
         if (in_array($permission, $ignore)) {
         return true;
      }

         $user_group_info = $this->CI->users_model->getUser($user_id);

         if (!empty($user_group_info)) {                

            $user_group_data = $this->CI->users_group_model->getUserGroup($user_group_info['user_group_id']);
         // Error Here
         if (!in_array($permission ,$user_group_data['permission']['modify'] )) {

            return false;

         } else {

            return true;

         }

         } else {

            return false;

         }  

      } else {

         return true;

      }

   }

不确定$this->CI->users_group_model->getUserGroup()究竟是什么 - 但是如果不存在则应该检查索引，然后再执行in_array并进一步检查变量$user_group_data以查看其外观并通过getUserGroup函数查看它返回的内容。请参阅以下函数的修改：

public function hasPermissionModify() 
{
    $user_id = $this->CI->session->userdata('user_id');
    $segment = $this->CI->uri->segment_array();                
    $permission = isset($segment[2]) ? $segment[2] : '';  

    $ignore = array(
        'blank',
        'error',
        'register',
        'dashboard',
        'column_left',
        'menu',
        'startup',
        'login',
        'logout',
        'forgotten',
        'reset',
        'not_found',
        'permission',
        'footer',
        'header'
    );

    if (isset($permission) && $permission && $user_id) 
    { 
        if (in_array($permission, $ignore)) 
        {
            return true;
        }

        $user_group_info = $this->CI->users_model->getUser($user_id);

        if(!empty($user_group_info)) 
        {                

            $user_group_data = $this->CI->users_group_model->getUserGroup($user_group_info['user_group_id']);
            // Error Here

            //$user_group_data does not have an index called modify. 
            //Examine it here and check getUserGroup function to see what is wrong
            echo "value of user_group_data:<pre>".print_r($user_group_data,true)."</pre>";

            //in any case if that index is not there return false
            if((!array_key_exists('permission',$user_group_data)) ||
            (!array_key_exists('modify',$user_group_data['permission']))
            {
                return false;
            }

            if (!in_array($permission ,$user_group_data['permission']['modify'] )) 
            {
                return false;
            } 
            else 
            {
                return true;
            }
        } 
        else 
        {
            return false;
        }  
    } 
    else 
    {
        return true;
    }

}
