控制器

<?php

class Testcontroller extends CI_Controller {


    // --------------------------------------------------------------------

    /**
     *  The constructor
     */
    function __construct()
    {
        parent::__construct();  



    }


    function index() {


    $data = array('title' => 'My Title',
              'heading' => 'My Heading',
              'message' => 'My Message');

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

    }
}

?>

测试视图

<?php   var_dump($data); ?>

推荐答案

$ data 在视图中不存在.相反，在给定数组 $ data 中，每个键只有一个变量.因此，在您的情况下，您有 $ title ， $ heading 和 $ message .

$data doesn't exist in the view. Instead you have one variable per key in the given array $data. So, in your case you have $title, $heading and $message.

请记住，传递的数据可以是匿名数组:

Bear in mind that the passed data could be an anonymous array:

$this->load->view('test', array('title' => 'My Title',
              'heading' => 'My Heading',
              'message' => 'My Message'));
