在CakePHP中使用jQuery Ajax发布到控制器 [英] Posting to controller with jquery ajax in CakePHP

问题描述

我想将数据发布到CakePHP中的控制器，但是使用JQuery进行发布始终会导致错误，并且我不知道为什么。

I want to post data to a controller in CakePHP, but posting with JQuery always results in an error and I can't figure out why.

在我看来我有以下方法，将数据发布到控制器页面

In my view I have the following method, that posts the data to the controller page

function RenameNode(name, id)
{
    $.ajax({
        type: "POST",
        url: '<?php echo Router::url(array('controller' => 'categories', 'action' => 'rename')); ?>',
        data: {
            id: id,
            name: name
        },
        success: function(){

        }
    });
}

我的控制器方法如下：

public function rename($id = null, $name = null) {
    if ($this->request->is('get')) {
        throw new MethodNotAllowedException();
    }

    if(!$id)
    {
        $id = @$this->request->query('id');
    }

    if(!$name)
    {
        $name = @$this->request->query('name');
    }           

    if (!$id) {
        throw new NotFoundException(__('No id'));
    }

    $category = $this->Category->findById($id);
    if (!$category) {
        throw new NotFoundException(__('Invalid category'));
    }

    $this->autoRender = false;
    $this->layout = 'ajax';

    if ($this->request->is('post') || $this->request->is('put')) {
        $this->Category->id = $id;
        $this->request->data['Category']['name'] = $name;


        if ($this->Category->save($this->request->data)) {
            $this->Session->setFlash(__('The category has been updated.'));
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('Unable to update the category.'));
        }
    }
}

我在jQuery方法，我在日志中不断收到以下错误消息：

When I do a post with the jquery method, I keep getting the following error message in my log:

2013-05-20 11:34:25 Error: [NotFoundException] No id
Request URL: /cakephp/categories/rename
Stack Trace:
#0 [internal function]: CategoriesController->rename()

当我评论请求检查get和post时，当我使用/ categories / rename？id进行调用时，控制器本身可以完美地工作= 1& name =测试。由于某种原因，ajax方式不起作用，但我不知道为什么。有任何想法吗？

When I comment the request checks for get and post, the controller itself works perfectly when I call it with /categories/rename?id=1&name=test. For some reason the ajax way doesn't work, but I can't figure out why. Any ideas?

更新

我通过更改以下代码对其进行了修复，现在可以正常使用了

I fixed it by changing the following code, now it works perfectly

    if(!$id)
    {
        $id = @$this->request->query('id');
    }

    if(!$name)
    {
        $name = @$this->request->query('name');
    }

至

    if(!$id)
    {
        $id = @$this->request->data('id');
    }

    if(!$name)
    {
        $name = @$this->request->data('name');
    }

推荐答案

您不包括<您发布到的URL中的code> id 和/或 name ；

echo Router::url(array('controller' => 'categories', 'action' => 'rename'));

会输出；

/categories/rename

但是您正在期待

/categories/rename/1/test

或

/categories/rename?id=1&name=test

将AJAX代码中的URL更改为类似的内容；

Change the URL in your AJAX code to something like;

echo Router::url(array(
   'controller' => 'categories',
   'action' => 'rename',
   0 => $this->request->params['pass'][0],
   1 => $this->request->params['pass'][1]
));

应该输出正确的网址，其中包含原始 <$ c $当前请求的c> id 和 name （例如/ categories / rename / 123 / oldname）

Which should output the right url, containing the original id and name of the current request (e.g. /categories/rename/123/oldname)
