CodeIgniter动态方法调用

Question

我有一个带有一些"过滤器"的数据库; 即方法调用,并希望能够根据用户输入的内容动态调用它们.

Code Igniter似乎不喜欢这样,有什么想法吗？它输出:在GetEmailCountfilter_male_count()中:

<h4>A PHP Error was encountered</h4>

<p>Severity: Notice</p>
<p>Message:  Undefined property: Targeted_Email::$filter_male_count()</p>
<p>Filename: core/Model.php</p>
<p>Line Number: 51</p>

{"emailCount":null}

码:

 public function getEmailCount($filter){
      echo 'In GetEmailCount';
      $result = array();
      $query = $this->db->get('base_targeted_email_filters');


      foreach ($query->result() as $row){
           if($filter == $row->name){

                $test = $row->filterCountFunction . "()";
                     echo $test;
                $result['emailCount'] = $this->{$test};
           }

  return $result
  }

Answer 1

foreach循环应该是这样的:

$test = $row->filterCountFunction;
$this->{$test}();
