在 Woocommerce 购物车页面中的购物车项目名称后添加产品 ID [英] Add the product ID after the cart item name in Woocommerce cart page

问题描述

我希望连接到 woocommerce 中的woocommerce_cart_item_name"过滤器，并希望在名称后显示产品 ID.到目前为止，我正在处理这个......

I'm looking to hook into the 'woocommerce_cart_item_name' filter in woocommerce and would like to display the product ID after the name. I'm working with this so far...

add_filter( 'woocommerce_cart_item_name', 'justatest' );

function justatest( $productname ) {
    echo $productname;
    // ideally echo name and product id here instead
}

这将返回带有链接的名称，但我想在项目名称后添加产品的实际 ID.

This returns the name with a link around it but I want to add the actual ID of the product after the item name.

如何在 Woocommerce 购物车页面中的购物车项目名称后添加产品 ID?

How can I add the product ID after the cart item name in Woocommerce cart page?

我知道我不需要先返回，因为那会使我退出函数，但我很好奇我将如何执行此操作.

I know I'd need to not return first since that will pull me out of the function, but I'm curious how I'd go about doing this.

推荐答案

您的挂钩函数中缺少一些参数，您应该进行一些更改以通过这种方式获取产品 ID:

There are some missing arguments in your hooked function and you should need to make some changes to get the product Id this way:

add_filter( 'woocommerce_cart_item_name', 'just_a_test', 10, 3 );
function just_a_test( $item_name,  $cart_item,  $cart_item_key ) {
    // Display name and product id here instead
    echo $item_name.' ('.$cart_item['product_id'].')';
}

此代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

经过测试并有效.
