在WooCommerce购物车和结帐表中显示产品自定义字段值 [英] Display a product custom field value in WooCommerce cart and checkout table
问题描述
在WooCommerce中,我为每个产品添加了一个自定义字段说明。
我能够找到一种同时显示标签名称和值的方法:
In WooCommerce and I have added a custom field "description" for each product. I was able to find a way to show both, the label name and the value:
add_filter( 'woocommerce_add_cart_item_data', 'save_days_field', 10, 2 );
function save_days_field( $cart_item_data, $product_id ) {
$special_item = get_post_meta( $product_id , 'description',true );
if(!empty($special_item)) {
$cart_item_data[ 'description' ] = $special_item;
// below statement make sure every add to cart action as unique line item
$cart_item_data['unique_key'] = md5( microtime().rand() );
WC()->session->set( 'description', $special_item );
}
return $cart_item_data;
}
// Render meta on cart and checkout
add_filter( 'woocommerce_get_item_data','rendering_meta_field_on_cart_and_checkout', 10, 2 );
function rendering_meta_field_on_cart_and_checkout( $cart_item_data, $cart_item ) {
if( isset( $cart_item['description'] ) ) {
$cart_item_data[] = array( "name" => __( "Description", "woocommerce" ), "value" => $cart_item['description'] );
}
return $cart_item_data;
}
现在我只需要显示值(而不是标签名称 Description )中的购物车和结帐表中的此自定义字段。我需要显示< small>
,就像我用以下代码显示的属性一样:
Now I need to display ONLY the value (not the label name "Description") of this custom field in the cart and checkout table. I need to display with <small>
, like the attribute I am displaying with this code:
add_filter('woocommerce_cart_item_name', 'wp_woo_cart_attributes', 10, 2);
function wp_woo_cart_attributes($cart_item, $cart_item_key){
$productId = $cart_item_key['product_id'];
$product = wc_get_product($productId);
$taxonomy = 'pa_color';
$value = $product->get_attribute($taxonomy);
if ($value) {
$label = get_taxonomy($taxonomy)->labels->singular_name;
$cart_item .= "<small>$value</small>";
}
return $cart_item;
}
如何在此自定义字段中使其仅显示值?
How can I make it for this custom field, displaying the value only?
推荐答案
您无需将产品自定义字段包含为自定义购物车项目数据,因为可以从产品对象直接访问该字段(或产品ID)。
You don't need to include a product custom field as custom cart item data, as it's directly accessible from the product object (or the product ID).
注意:在购物车商品变量 $ cart_item
,包含 WC_Product
对象,并可以通过 $ cart_item ['data'] $ c使用$ c>
。
Note: On a cart item variable $cart_item
, the WC_Product
Object is included and available using $cart_item['data']
.
尝试以下操作在购物车和结帐页面中的商品名称后添加自定义字段:
Try the following to add a custom field after the item name in cart and checkout pages:
// Display in cart and checkout pages
add_filter( 'woocommerce_cart_item_name', 'customizing_cart_item_name', 10, 3 );
function customizing_cart_item_name( $product_name, $cart_item, $cart_item_key ) {
$product = $cart_item['data']; // Get the WC_Product Object
if ( $value = $product->get_meta('description') ) {
$product_name .= '<small>'.$value.'</small>';
}
return $product_name;
}
要在订单和电子邮件通知中显示,请使用:
To display it on orders and email notifications use:
// Display in orders and email notifications
add_filter( 'woocommerce_order_item_name', 'customizing_order_item_name', 10, 2 );
function customizing_order_item_name( $product_name, $item ) {
$product = $item->get_product(); // Get the WC_Product Object
if ( $value = $product->get_meta('description') ) {
$product_name .= '<small>'.$value.'</small>';
}
return $product_name;
}
代码进入活动子主题(或活动主题)的function.php文件)。经过测试,可以正常工作。
Code goes in function.php file of your active child theme (or active theme). Tested and works.
