添加操作woocommerce_add_to_cart断开网站原始添加到购物车功能

Question

我构建了一个节点Express API，并让IT收听来自Woocommerce_add_to_cart webhook的帖子请求，但是从中的有效载荷本质上是毫无价值的。

body:{ action: 'woocommerce_add_to_cart', arg:'098uoijo098920sa489983jk' }

有没有办法将产品数据添加到这些Webhooks中？如果不想从functions.php函数发送php curl请求，例如so

我的functions.php函数：

function custom_add_to_cart($cart_item_key, $product_id, $quantity, 
    $variation_id, $variation, $cart_item_data){
        //added this just to see if my event function even gets called, doesn't appear to 
        echo'<pre>';var_dump($product_id);echo'</pre>';die();
        $product_info = json_encode(array($product_id => wc_get_product($product_id)));
        $request_args = array(
           'httpversion' => '1.1',
           'headers' => 'Content-Type:application/json',
           'body' => $product_info,
    );
    $response = wp_safe_remote_post("myapp.com/endpoint", $request_args);
}
add_action('woocommerce_add_to_cart', 'custom_add_to_cart', 10, 6);

这导致网站添加到购物车功能中断，因此我的假设是Basel使用此操作钩并将其再次添加到functions.php会导致错误。查看旧段插件，他们也将此事件用于此目的，因此必须在多个位置使用此钩子。

发生错误的代码段：

   a.ajax({
        url: basel_settings.ajaxurl,
        data: e,
        method: "POST",
        success: function(b) {
            if (b) {
                var c = window.location.toString();
                if (c = c.replace("add-to-cart", "added-to-cart"),
                b.error && b.product_url)
                    return void (window.location = b.product_url);
                if ("yes" === wc_add_to_cart_params.cart_redirect_after_add)
                    return void (window.location = wc_add_to_cart_params.cart_url);
                d.removeClass("loading");
                var e = b.fragments
                  , f = b.cart_hash;
                e && a.each(e, function(b) {
                    a(b).addClass("updating")
                }),
                e && a.each(e, function(b, c) {
                    a(b).replaceWith(c)
                }),
                //line where error gets reported
                b.notices.indexOf("error") > 0 ? (a(".woocommerce-error").length > 0 && a(".woocommerce-error").remove(),
                a(".single-product-content").prepend(b.notices),
                d.addClass("not-added")) : ("widget" == basel_settings.add_to_cart_action && a.magnificPopup.close(),
                d.addClass("added"),
                a(document.body).trigger("added_to_cart", [e, f, d]))
            }
        },
        error: function() {
            console.log("ajax adding to cart error")
        },
        complete: function() {}
    })

错误：

Uncaught TypeError: Cannot read property 'indexOf' of undefined
    at Object.success (theme.min.js?ver=4.0.0:formatted:17037)
    at i (jquery.js?ver=1.12.4:2)
    at Object.fireWith [as resolveWith] (jquery.js?ver=1.12.4:2)
    at y (jquery.js?ver=1.12.4:4)
    at XMLHttpRequest.c (jquery.js?ver=1.12.4:4)

当我从functions.php中删除函数时，产品会正确添加到购物车中，没有错误。

我是否需要在插件中而不是functions.php中添加此功能？

我想只是注意到不存在，所以你需要守护它您可以尝试，

           //line where error gets reported
         if(b.notices){
            b.notices.indexOf("error") > 0 ? (a(".woocommerce-error").length > 0 && a(".woocommerce-error").remove(),
            a(".single-product-content").prepend(b.notices),
            d.addClass("not-added")) : ("widget" == basel_settings.add_to_cart_action && a.magnificPopup.close(),
            d.addClass("added"),
            a(document.body).trigger("added_to_cart", [e, f, d]))
         }
