Codeigniter将数据从控制器传递到视图 [英] Codeigniter passing data from controller to view

问题描述

根据此处，我有以下控制器：

As per here I've got the following controller:

class User extends CI_Controller {
    public function Login()
    {
        //$data->RedirectUrl = $this->input->get_post('ReturnTo');
        $data = array(
               'title' => 'My Title',
               'heading' => 'My Heading',
               'message' => 'My Message'
          );
        $this->load->view('User_Login', $data);
    }

    //More...
}

并在我的 User_Login.php 查看文件中，我这样做：

and in my User_Login.php view file I do this:

<?php print_r($data);?>

其结果是：

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: data
Filename: views/User_Login.php
Line Number: 1

我需要加载任何特定的模块/ helpers来获取$ data变量填充吗？如果我 print_r（$ this），我可以看到很多东西，但我的数据除了在缓存

Do I need to load any specific modules/helpers to get the $data variable populated? If I print_r($this), I can see a lot of stuff but none of my data except in caches

编辑：为了澄清，我知道调用变量在控制器和视图相同不会共享它 - 它超出范围，但在我链接的例子，似乎暗示一个 $ data 变量在视图的作用域中创建。我只是碰巧在控制器中使用相同的名称

To clarify, I know that calling the variable the same in the controller and view won't "share" it - it's out of scope but in the example I linked, it seems to imply a $data variable is created in the scope of the view. I simply happened to use the same name in the controller

推荐答案

啊， $ data 数组的键被转换为变量：try var_dump（$ title）;例如

Ah, the $data array's keys are converted into variables: try var_dump($title); for example.

：这是使用解压缩完成的。
