php - 在 Woocommerce 中获取订单标题

Question

我试图通过我的 functions.php 文件循环获取订购产品的名称。这是我的代码:

global $woocommerce;
$items = $woocommerce->cart->get_cart();

foreach($items as $item => $values) { 
    $_product = $values['data']->post; 
} 

然后我这样命名标题:

$_product->post_title

这有效，它返回我订购的产品的名称。问题是当我有 2 种或更多产品时，它仍然会返回 1 个名称。我怎样才能让它返 repo 物车中的所有名称。

woocommerce 中与购物车相关的新语法是使用 WC() 制作的 无需调用 global woocommerce;

所以你的代码将是这样的:

$products_in_cart= array();
$products_post_title_in_cart = array();
$products_ids_in_cart= array();

foreach(WC()->cart->get_cart() as $cart_item) {
    $products_in_cart[] = $cart_item['data']->post;
    $products_post_title_in_cart[] = $cart_item['data']->post->post_title;
    $products_ids_in_cart[] = $cart_item['product_id'];
}

// The first product (or item of the cart)
$_product = $products_in_cart[0]; // product post data
$product_id = $products_ids_in_cart[0]; // product ID
$products_post_title_in_cart[0] // product post title

// The Second product (or item of the cart)
$_product = $products_in_cart[1]; // product post data
$product_id = $products_ids_in_cart[1]; // product ID
$products_post_title_in_cart[1] // product post title

// etc … for all other products you increase the key of the arrays to get the correct values
