如何获取 Woocommerce 购物车详细信息

Question

我想将 woocommerce 购物车详细信息（商品名称和价格）解析为网站标签中的 javascript 代码。

我尝试使用我的子主题中的函数来获取它。

add_action( 'wp', 'push' );
function push() {
foreach ( WC()->cart->get_cart() as $cart_item ) {
   $item_name = $cart_item['data']->get_title();
   $quantity = $cart_item['quantity'];
   $price = $cart_item['data']->get_price();
}
}

但它没有显示任何值。

这是我的javascript代码

<script>
window._peq.push(["add-to-trigger",{
    "campaign_name": "Abandon Cart - 10 percent discount",
    "event_name": "add-to-cart",
    "title": {
        "productname": "item_name",
        "price": "price"
    },
    "message": {
        "price": "price"
    },
    "notification_url": {
        "notificationurl": "https://www.photography-raw.com/store/checkout/"
    },
    "notification_image": {
        "imageurl": ""
    },
    "big_image": {
        "bigimageurl": ""
    }
}]);
</script>

谁能帮帮我。提前致谢
