Wordpress 在woocommerce中使用表达式获取产品名称

我可以使用表达式{Order_ID}获得订单ID，如下面的屏幕截图所示

这是一个支付网关插件，所以编辑插件文件将是我最不想做的事情。谢谢

一些知识分子投票否决了我的问题，没有透露他们的知识基础。但对于像我这样的穷人，我发现：

文件：plugins/telr/class-wc-gateway-telr-checkout-handler.php

方法：私有函数生成_请求（$order）

查找：

替换为：

$cart_desc = trim(wc_gateway_telr()->settings->__get('cart_desc'));
if (empty($cart_desc)) {
    $cart_desc ='Order {order_id}';
}

$order_items = $order->get_items();
$productNames = array();
foreach ($order_items as $product_data) {
    $productInfo = $product_data->get_data();
    $productNames[] = $productInfo['name'];
}
$cartProducts = implode(", ", $productNames);
$cart_desc  = preg_replace('/{order_id}/i', $order_id, $cart_desc);
$cart_desc  = preg_replace('/{product_names}/i', $cartProducts, $cart_desc);
$cart_desc = substr($cart_desc, 0, 63);
add_post_meta($order_id, '_telr_cartdesc', $cart_desc);

在此之后，{product_names}将替换为“，”，分隔的产品名称和最终描述字符串将被修剪到63个字符（因为这是描述可以具有的长度）

$cart_desc = trim(wc_gateway_telr()->settings->__get('cart_desc'));
if (empty($cart_desc)) {
    $cart_desc ='Order {order_id}';
}

$order_items = $order->get_items();
$productNames = array();
foreach ($order_items as $product_data) {
    $productInfo = $product_data->get_data();
    $productNames[] = $productInfo['name'];
}
$cartProducts = implode(", ", $productNames);
$cart_desc  = preg_replace('/{order_id}/i', $order_id, $cart_desc);
$cart_desc  = preg_replace('/{product_names}/i', $cartProducts, $cart_desc);
$cart_desc = substr($cart_desc, 0, 63);
add_post_meta($order_id, '_telr_cartdesc', $cart_desc);
