AutoRender = False在CakePHP中不起作用

问题描述

曾经试图弄清楚几个小时，但无法正常工作！

Been trying to figure this out for hours but can't get it to work!

我正在关注使用Ajax和Ajax实现简单的购物车功能CakePHP

I'm following this tutorial to implement a simple shopping cart feature using Ajax and CakePHP

在CartsController中，我们必须设置：$ this-> autoRender = false;因为Ajax调用不需要加载 ADD视图。但是，当我单击添加到购物车按钮时，它将返回一个空白页，其中包含正确的数量编号。如果我返回上一页并刷新它，则可以看到该商品已添加到购物车。

In the CartsController, we have to set: $this->autoRender = false; since the Ajax call doesn't need to load the 'ADD' view. However, when I click the 'Add to Cart' button, it returns a blank page with the correct quantity number. If I go back a page and refresh it, then I can see the item has been added to the cart.

如何禁用此空白页面（数量为）

How do I disable this blank page (with the qty) from loading and have Ajax just update the cart counter?

CakePHP：

public function add() {
$this->autoRender = false;

if ($this->request->is('post')) {
    $this->Cart->addProduct($this->request->data['Cart']['product_id']);
}

echo $this->Cart->getCount();
}

仅供参考：

• addProduct只会在会话中循环访问数组，并增加变量（如果找到）或添加到数组（如果未找到）


• getCount只会返回

Ajax：

<script>
    $(document).ready(function(){
        $('#add-form').submit(function(e){
            e.preventDefault();
            var tis = $(this);
            $.post(tis.attr('action'),tis.serialize(),function(data){
                $('#cart-counter').text(data);
            });
        });
    });
</script>

仅供参考，我在default.ctp中引用了jQuery：

FYI, I'm making this reference to jQuery in my default.ctp:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

推荐答案

请确保在自定义JavaScript代码之前添加了jQuery 。否则，将不会加载 $ 变量，并且您的ajax调用也将根本不会执行。

Please check that jQuery is added before your custom javascript code. If not, the $ variable won't be loaded and your ajax call won't execute at all.
