在 WooCommerce 中添加到购物车并提交 Facebook Pixel 的订单

Question

我几天来都在拼命尝试在 Facebook Pixel 中获得 AddToCart 和 Purchase Tracking 的独特跟踪。默认设置为 0.00 会导致错误的转换结果。

我几天来都在拼命尝试在 Facebook Pixel 中获得 AddToCart 和 Purchase Tracking 的独特跟踪。默认设置为 0.00 会导致错误的转换结果。

我们正在使用 WooCommerce，我正在通过标签管理器实现 FB Pixel。

所有事件都在跟踪，但我想获取 AddToCart 的 AddToCart 值和购买时的购物车总金额。 WooCommerce 正在使用数据层，我尝试使用 ecomm_total 和价格的数据层，但出现错误

无效的 AddToCart 值参数

我们的代码示例如下

我可以用任何值替换 0.00 以获得每个产品和订单的正确值吗？

<script>
fbq('track', 'AddToCart', {
value: 0.00,
currency: 'SEK',
});
</script>

根据Conditional Logic and custom FB Pixels Integration into WooCommerce的回答码，下面将从“AddToCart”和“Purchase”事件中设置主要事件和价格值：

// Function that gets the Ajax data
add_action( 'wp_ajax_product_added_to_cart', 'wc_product_added_to_cart' );
add_action( 'wp_ajax_nopriv_product_added_to_cart', 'wc_product_added_to_cart' );
function wc_product_added_to_cart() {
    if ( isset($_POST['pid']) ){
        // Get an instance of the WCW_Product Object
        $product = wc_get_product( $_POST['pid'] );

        // Return the product price including taxes
        echo number_format( wc_get_price_including_tax( $product ), 2 );

        // OR =>the product price EXCLUDING taxes
        // echo number_format( wc_get_price_excluding_tax( $product ), 2 );
    }
    die(); // Alway at the end (to avoid server error 500)
}

// FB PiXELS HEAD Script (Initializing)
add_action( 'wp_head', 'fbpixels_head_script' );
function fbpixels_head_script() {

代码进入您的活动子主题（或活动主题）的 function.php 文件中。它似乎有效。
