Question

我使用以下代码将自定义帖子类型的自定义字段用作价格字段。这样我就可以在购物车中添加此字段值并进行付款。

好消息是这个自定义帖子成功进入购物车，但问题是价格值错误。

价格应该是400美元，但它显示51,376美元。

以下是代码：

if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {
// Put your plugin code here

add_action('woocommerce_loaded' , function (){
    //Put your code here that needs any woocommerce class
    //You can also Instantiate your main plugin file here
    class WCCPT_Product_Data_Store_CPT extends WC_Product_Data_Store_CPT
    {

        /**
         * Method to read a product from the database.
         * @param WC_Product
         */

        public function read(&$product)
        {

            $product->set_defaults();

            if (!$product->get_id() || !($post_object = get_post($product->get_id())) || !in_array($post_object->post_type, array('refered_customer', 'product'))) { // change birds with your post type
                throw new Exception(__('Invalid product.', 'woocommerce'));
            }

            $id = $product->get_id();

            $product->set_props(array(
                'name' => $post_object->post_title,
                'slug' => $post_object->post_name,
                'date_created' => 0 < $post_object->post_date_gmt ? wc_string_to_timestamp($post_object->post_date_gmt) : null,
                'date_modified' => 0 < $post_object->post_modified_gmt ? wc_string_to_timestamp($post_object->post_modified_gmt) : null,
                'status' => $post_object->post_status,
                'description' => $post_object->post_content,
                'short_description' => $post_object->post_excerpt,
                'parent_id' => $post_object->post_parent,
                'menu_order' => $post_object->menu_order,
                'reviews_allowed' => 'open' === $post_object->comment_status,
            ));

            $this->read_attributes($product);
            $this->read_downloads($product);
            $this->read_visibility($product);
            $this->read_product_data($product);
            $this->read_extra_data($product);
            $product->set_object_read(true);
        }

        /**
         * Get the product type based on product ID.
         *
         * @since 3.0.0
         * @param int $product_id
         * @return bool|string
         */
        public function get_product_type($product_id)
        {

            $post_type = get_post_type($product_id);
            if ('product_variation' === $post_type) {
                return 'variation';
            } elseif (in_array($post_type, array('refered_customer', 'product'))) { // change birds with your post type
                return false;
            } else {
                return false;
            }
        }
    }
});

}

add_filter( 'woocommerce_data_stores', 'woocommerce_data_stores' );

function woocommerce_data_stores ( $stores ) {

$stores['product'] = 'WCCPT_Product_Data_Store_CPT';

return $stores;

}

add_filter('woocommerce_product_get_price', 'woocommerce_product_get_price', 10, 2 );

function woocommerce_product_get_price( $invoice_price, $product ) {

if ($post->post->post_type === 'refered_customer') // change birds with your post type

    $invoice_price = get_post_meta($post->id, "invoice_price", true);

return $invoice_price;

}

已更新 - 在您上次挂钩的功能中，为了获得合适的价格，您会遇到一些错误：

$post->post->post_type 无法使用，因为$post对象未定义。
$post->id应为$post->ID，但不起作用，因为$post对象未定义。

相反，您将使用专用函数和方法：get_post_type()和$product->get_id()。

所以试试这个：

add_filter('woocommerce_product_get_price', 'woocommerce_product_get_price', 10, 2 );
function woocommerce_product_get_price( $price, $product ) {
    // Change birds with your post type
    if ( get_post_type( $product->get_id() ) === 'refered_customer' )
        $price = get_post_meta( $product->get_id(), "invoice_price", true );

    return $price;
}

代码放在活动子主题（或活动主题）的function.php文件中。它现在应该有效。
