如何将值从视图传递到控制器

Question

这是我的控制器代码

$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);

在视图代码中，我将向控制器发送$ id，但显示未定义的变量'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;
  }

}

Answer 1

安装：

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

尝试：

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

Answer 2

您的代码如下所示

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

这是因为您没有在查询的数据中放入$ id

因此<?php print_r($query); ?> <?php print_r($query); ?>
