CodeIgniter传递数据到视图 [英] CodeIgniter passing data to the view

问题描述

我试图从我的控制器传递到这样的视图...

  public function playerslist $ b {
 $ this-> load-> database（）; 
 $ data = $ this-> db-> get（'skaters'）; 
 $ this-> load-> helper（'url'）; 
 $ this-> load-> view（'playerslist'，$ data）; 
} 
  

在我看来...

 <？php echo $ data; > 
  

但我收到此错误...
$ b

遇到PHP错误

严重性：通知

$ b b

讯息：未定义的变数：data

档案名称：views / playerslist.php

< 76

我做错了什么？

这些数据放在一个foreach语句中并显示$ data数组中的所有内容

  foreach（$ data as $ value = > $ key）{
 echo $ key。 < br />; 
} 
  

谢谢
J

解决方案

您不能直接从视图中访问 $ data 。传递给视图的 $ data 必须是关联数组。

例如：

 <$> c $ c> $ data = array（
'name'=>'John'，
'bars'=> 23 
）; 
 
 $ this-> load-> view（'playerslist'，$ data）; 
  

然后，在您的视图中，这些将被转换为变量：

 <？php echo $ name; > has<？php echo $ bars; >巧克力。 
  

---

如果要访问其原始数据格式，将 传递到关联数组中：

  $ data = $ this-& > get（'skaters'） - > result（）; 
 $ this-> load-> view（'playerslist'，array（'data'=> $ data））; 
  

I am trying to pass from my controller to the view like so...

public function playerslist()
    {
        $this->load->database();
        $data = $this->db->get('skaters');
        $this->load->helper('url');
        $this->load->view('playerslist', $data);
    }

and in my view...

<?php echo $data; ?>

but I get this error...

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: data

Filename: views/playerslist.php

Line Number: 76

What am I doing wrong?

What I would like to do with this data is put in a foreach statement and display everything in the $data array

foreach($data as $value => $key){
echo $key . "<br/>";
}

Thanks, J

解决方案

You cannot access $data directly from your view. The $data you pass to your view has to be an associative array. The keys will then be converted to variables in your view.

For example:

$data = array(
    'name' => 'John',
    'bars' => 23
);

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

Then, in your view, those will be converted to variables:

<?php echo $name; ?> has <?php echo $bars; ?> bars of chocolate.

---

If you want to access the data in its original format, pass that into the associative array:

$data = $this->db->get('skaters')->result();
$this->load->view( 'playerslist', array('data' => $data) );
