Woocommerce aJax将优惠券代码应用于购物篮 [英] Woocommerce aJax apply coupon code to basket

问题描述

我试图在按下按钮时将优惠券代码应用于购物篮.我有以下代码:-

I am attempting to apply a coupon code to the basket on a button press. I have the following code:-

coupon = jQuery(this).data('coupon');
data = {coupon_code : coupon};
jQuery.post( "?wc-ajax=apply-coupon", { coupon_code: coupon }).done(function( data ) {
    alert( "Data Loaded: " + data );
});

我可以看到以下数据正在解析到服务器:-

I can see the following data is being parsed to the server:-

coupon_code: 10percentdiscount

10percentdiscount 存在.

我发送请求后，服务器未发回响应.

The Server is not sending back a response once I have sent the request.

我是正确发出此请求还是其他方法?

Am I correctly making this request or is there another way?

谢谢.

推荐答案

我会这样做:

在header.php或页面中定义ajax网址，您是否要添加优惠券

Define ajax url in header.php or in page would you add coupon

<script type="text/javascript" language="javascript">
var ajax_url = "<?php bloginfo('url'); ?>/wp-admin/admin-ajax.php";
</script>

在function.php中，您必须定义ajax调用

In function.php you must define ajax call

function implement_ajax() {
    include(TEMPLATEPATH . '/ajax_return.php');
}

add_action('wp_ajax_my_special_action', 'implement_ajax');
add_action('wp_ajax_nopriv_my_special_action', 'implement_ajax');

在ajax_return.php中，您输入了将优惠券添加到woocommerce的代码:

In ajax_return.php you past code that add coupon to woocommerce:

if (isset($_POST['couponcode']))
    { apply_coupon($_POST['couponcode']); }; 

function apply_coupon($couponcode) { 
    global $woocommerce; WC()->cart->remove_coupons();
    $ret = WC()->cart->add_discount( $couponcode ); 
    $array = array('return' => $ret); print_r($array); 
}
exit;

您的jQuery.post会变成这样:

Your jQuery.post will became this:

<script type="text/javascript">
jQuery(function(){
    coupon = jQuery(this).data('coupon');
    jQuery.post(ajax_url, {action : 'my_special_action', couponcode : coupon}, return_function, 'JSON');
});

function return_function(data)
{
   console.log(data.return); //contains true if coupon was applied
}
</script>

如果需要，请调用return_function来管理响应.

If you need, call return_function to manage response.
