这是我的代码

但是现在我需要在产品页面上添加一些自定义字段,一个包含“黑色”和“白色”颜色的下拉列表,这只是一个普通的下拉列表。当我选择一个将显示在产品名称下的购物车上的值时,我该怎么做
【问题讨论】:
【参考方案1】:更新 2
尝试以下操作(通常会在单个产品页面中添加下拉菜单并在购物车项目中保存/显示所选值):
// Frontend: custom select field (dropdown) in product single pages
add_action( 'woocommerce_before_add_to_cart_button', 'fabric_length_product_field' );
function fabric_length_product_field()
global $product;
// Select field
woocommerce_form_field('fitting_color', array(
'type' => 'select',
'class' => array('my-field-class form-row-wide'),
'label' => __('_fitting_color', 'woocommerce'),
'required' => true, // or false
'options' => array(
'' => __('Select a color', 'woocommerce'),
'black' => __('Black', 'woocommerce'),
'white' => __('White', 'woocommerce'),
),
),'');
// Add "fitting_color" selected value as custom cart item data
add_filter( 'woocommerce_add_cart_item_data', 'add_custom_cart_item_data', 20, 2 );
function add_custom_cart_item_data( $cart_item_data, $product_id )
if( isset($_POST['fitting_color']) && ! empty($_POST['fitting_color']))
$cart_item_data['fcolor']= array(
'value' => esc_attr($_POST['fitting_color']),
'unique_key' => md5( microtime() . rand() ), // <= Make each cart item unique
);
return $cart_item_data;
// Display custom cart item data in cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'display_custom_cart_item_data', 10, 2 );
function display_custom_cart_item_data( $cart_item_data, $cart_item )
if ( isset( $cart_item['fcolor']['value'] ) )
$cart_item_data[] = array(
'name' => __( 'Fitting color', 'woocommerce' ),
'value' => $cart_item['fcolor']['value'],
);
return $cart_item_data;
代码在您的活动子主题(或活动主题)的 function.php 文件中。它应该可以工作。
为了保存/显示订单(并显示在电子邮件通知中),您将使用:
// Save chosen slelect field value to each order item as custom meta data and display it everywhere
add_action('woocommerce_checkout_create_order_line_item', 'save_order_item_product_fitting_color', 10, 4 );
function save_order_item_product_fitting_color( $item, $cart_item_key, $values, $order )
if( isset($values['fcolor']['value']) )
$key = __('Fitting color', 'woocommerce');
$value = $values['fcolor']['value'];
$item->update_meta_data( $key, $value );
以及缺少的字段验证:
// Field validation
add_filter( 'woocommerce_add_to_cart_validation', 'dropdown_fitting_color_validation', 10, 3 );
function dropdown_fitting_color_validation( $passed, $product_id, $quantity )
if( isset($_POST['fitting_color']) && empty($_POST['fitting_color']) )
wc_add_notice( __( "Please select a Fitting color", "woocommerce" ), 'error' );
return false;
return $passed;
【讨论】:
嗨 @loicTheAztec,它在常规 woo 产品上运行良好,但在自定义帖子类型页面上无法运行 我想我现在可以在 CPT 上使用它了,我刚刚删除了第一个操作 ( add_action( 'woocommerce_before_add_to_cart_button', 'fabric_length_product_field' ); ) 并将这个函数 (fabric_length_product_field()) 包含在 add to购物车形式以上是关于在产品中添加自定义字段以显示在购物车、结帐和订单中的主要内容,如果未能解决你的问题,请参考以下文章
