在 CakePHP 2.0 中使用 Html Helper 时未定义的变量

问题描述

我第一次尝试 CakePHP 时遇到此错误:

I am getting this error on my first attempt of CakePHP:

未定义变量:html [APP/View/Posts/index.ctp, line 13]

Undefined variable: html [APP/View/Posts/index.ctp, line 13]

我有 2.0-alpha 版本，我得到了错误的版本还是再次发生了变化.好像找不到html helper.

I have version 2.0-alpha, have I got the wrong version or what has changed again. Seems it can't find the html helper.

按要求提供更多信息:

这里是 index.ctp 文件

Here is the index.ctp file

<?php foreach ($posts as $post): ?>    

<?php echo $post['Post']['id']; ?>


<?php
##line 13 here
 echo $html->link($post['Post']['title'], array('controller' => 'posts', 'action' => 'view', $post['Post']['id'])); 
?>


<?php echo $post['Post']['created']; ?>

<?php endforeach; ?> 

数据肯定会通过，但我得到的错误是第 13 行:

The data is definitely coming through but the error I get is this on line 13:

未定义变量:html [APP/View/Posts/index.ctp, line 13] Fatal error: Call to a member function link() on an non-object in/home

Undefined variable: html [APP/View/Posts/index.ctp, line 13] Fatal error: Call to a member function link() on a non-object in /home

我是新手，希望能帮到你.

I'm quite new I hope this helps.

发疯5小时后更新

谢谢伙计们，它已排序，以防万一有人遇到这个问题，主站点上的教程是旧的，没有人努力更新它！！...在 index.ctp 示例中替换

Thanks guys it's sorted incase anybody has this problem the tutorial on the main site is an old one and nobody has made the effort to update it!! ...in the index.ctp example replace

$html->link(... 

与

$this->Html->link(...

推荐答案

从cakephp的manual上看，$html应该是$this->Html在 CakePHP 2.0 中.

From the manual of cakephp, it seems that $html should be $this->Html in CakePHP 2.0.
