WooCommerce的购物车数据存储在两个地方，一个是woocommerce_sessions数据表，另一个是在usermeta中，meta key是woocommerce_persistent_cart_[blog ID]，blog ID指multisite的site ID。本文介绍查看所有用户购物车的方法，当然，是用程序读取。

查看所有用户购物车的代码

从wp_woocommerce_sessions表中读取所有数据，代码只读取了10个，数据量很大时分页是必须的
session_key是user ID的就是注册用户，session_key是一个长长的字符串的代表游客
session_value里存储了所有购物车相关的数据，例如购物车里有什么产品，购物车的各种总价，税费，邮费等等。如果想知道具体有什么，可以var_dump一下 $cart_session变量。
$cart_session['cart']里存储了购物车产品，这里简单用程序把产品信息打印出来（ sola_list_cart_item 函数的作用）

/**
 * Get all carts data from wp_woocommerce_sessions table
 *
 */
function sola_get_all_carts_from_session() {
	global $wpdb;
	$carts = $wpdb->get_results("SELECT session_key,session_value FROM {$wpdb->prefix}woocommerce_sessions Limit 0,10");

	foreach ($carts as $cart) {

		$customer_id  = $cart->session_key;
		$cart_session = maybe_unserialize($cart->session_value);
		$cart_totals  = maybe_unserialize($cart_session['cart_totals']);
		$cart_total   = $cart_totals['total'];

		echo '<p>';

		if (is_numeric($customer_id)) {

			$user = new WP_User($customer_id);
			echo '注册用户: ' . $user->get('user_email');
		} else {

			echo '游客';
		}

		echo ', 购物车总价：', wc_price($cart_total), '<br>';

				// List products in cart
		sola_list_cart_item(maybe_unserialize($cart_session['cart']));

		echo '</p>';
	}
}

/**
 * List products of cart
 */
function sola_list_cart_item($cart_items) {
		// Loop through cart items and get cart items details
	foreach ($cart_items as $cart_item_key => $cart_item) {

		$product_id   = $cart_item['product_id'];
		$variation_id = $cart_item['variation_id'];
		$quantity     = $cart_item['quantity'];
		$attributes   = $cart_item['variation'];
		$item_taxes   = $cart_item['line_tax_data'];
		$subtotal_tax = $cart_item['line_subtotal_tax'];
		$total_tax    = $cart_item['line_tax'];
		$subtotal     = $cart_item['line_subtotal'];
		$total        = $cart_item['line_total'];

		$product = wc_get_product($product_id);

		echo '<a href="', $product->get_permalink(), '">', $product->get_title(), '</a>, 数量:', $quantity, ', 单价', $product->get_price_html(), '<br>';

	}
}

把代码做成shortcode运行一下的效果如下图所示：

根据用户ID列出购物车产品

function sola_get_cart_contents_by_user_id($user_id) {

	// Get an instance of the WC_Session_Handler Object
	$session_handler = new WC_Session_Handler();

	// Get the user session from its user ID:
	$session = $session_handler->get_session($user_id);

	// Get cart items array
	$cart_items = maybe_unserialize($session['cart']);

	sola_list_cart_item($cart_items);
}

能实现此功能的插件

这些插件主要用来实现abandoned cart营销，功能更为强大，Retainful是第三方服务，所有查看功能要去它的网站才行。
