Cakephp博客教程错误

Question

我是 cakephp 新手。我关注了这个http://book.cakephp.org/2.0/en/tutorials-and-examples/blog/part-two.html教程中，除了“编辑方法”之外，当我单击编辑链接时，它会给出以下警告消息并且不会编辑，一切都工作正常。

Warning (2): strtolower() expects parameter 1 to be string, array given [CORE/Cake/Network/CakeRequest.php, line 471]
Code Context
$type = array(
    (int) 0 => 'post',
    (int) 1 => 'put'
)
$this = object(CakeRequest) {
    params => array(
        'plugin' => null,
        'controller' => 'posts',
        'action' => 'edit',
        'named' => array([maximum depth reached]),
        'pass' => array(
            [maximum depth reached]

为了进一步澄清这一点，这是

$this->request->is(array('post', 'put'))

导致问题的调用，如CakeRequest::is()只能采取array从 CakePHP 2.4.0 开始，早期版本预计 string .

我不确定人们是否应该期望这些教程与旧版本兼容，但是，为了完整起见，在旧版本中，您必须使用多次调用 CakeRequest::is() :

$this->request->is('post') || $this->request->is('put')
