php - 如何将值从 View 传递到 Controller

Question

这是我的 Controller 代码

$data['query']= $this->webpages->get_where_custom('parent_id',0); 
// i  will get $id from view 
$data['query']=$this->webpages->get_where_custom('parent_id',$id);

$this->load->view-(template,$data);

在 View 代码中，我将发送 $id 到 Controller ，但它显示 undefined variable “id”

   <?php

   foreach($query->result() as $row){
       $id=$row->id;   // how to send this $id to my controller
       $page_url=$row->page_url;
       $parent_id=$row->parent_id;
       $page_headline=$row->page_headline;

  foreach($query->result() as $row){
       $page_url=$row->page_url;
       $page_headline=$row->page_headline;

  ?>
  echo $page headline;
  }

}

安装:

$this->load->view-(template,$data);

尝试:

$this->load->view(template,$data);
