我有一些自定义代码运行良好，并且由于我将Woocommerce更新到了3.5.2版，因此它不再起作用，不确定是因为我更改了wordpress主题还是因为插件更新了。
我的问题是自定义字段的值没有出现在woocommerce的订单页面上，甚至没有出现在订单电子邮件中。
这是相关代码：
// Display Fields using WooCommerce Action Hook
add_action('woocommerce_product_options_general_product_data', 'woocom_general_product_data_custom_field');
function woocom_general_product_data_custom_field()
{
// FieldName1
woocommerce_wp_text_input(array('id' => 'FieldName1', 'label' => __('FieldName1', 'woocommerce'), 'placeholder' => '', 'desc_tip' => 'false', 'description' => __('', 'woocommerce')));
// FieldType1
woocommerce_wp_text_input(array('id' => 'FieldType1', 'label' => __('FieldType1', 'woocommerce'), 'placeholder' => '', 'desc_tip' => 'false', 'description' => __('', 'woocommerce')));
// FieldLenght1
woocommerce_wp_text_input(array('id' => 'FieldLenght1', 'label' => __('FieldLenght1', 'woocommerce'), 'placeholder' => '', 'desc_tip' => 'false', 'description' => __('', 'woocommerce')));
// Dropdown1
woocommerce_wp_text_input(array('id' => 'Dropdown1', 'label' => __('Dropdown1', 'woocommerce'), 'placeholder' => '', 'desc_tip' => 'false', 'description' => __('', 'woocommerce')));
}
// Hook to save the data value from the custom fields
add_action('woocommerce_process_product_meta', 'woocom_save_general_proddata_custom_field');
function woocom_save_general_proddata_custom_field($post_id)
{
// Save Label Option 1
update_post_meta($post_id, 'FieldName1', esc_attr($_POST['FieldName1']));
// Save Label Option 1
update_post_meta($post_id, 'FieldType1', esc_attr($_POST['FieldType1']));
// Save Label Option 1
update_post_meta($post_id, 'FieldLenght1', esc_attr($_POST['FieldLenght1']));
// Save Dropdown1
update_post_meta($post_id, 'Dropdown1', esc_attr($_POST['Dropdown1']));
}

我一直在找几个小时，我不知道如何解决它或问题是什么。任何帮助或提示将非常有帮助。非常感谢。
答案 0 :(得分：1)
第一个主要问题是$cart_item_data['custom_data']['1'] = array(，应改为：
$cart_item_data['custom_data'] = array(
'label' => $label1,
'value' => sanitize_text_field( $_REQUEST['FieldTypeValue1'] ),
);
然后第二个主要问题是最后一个函数，其中woocommerce_get_item_data已过时，并由已经回答in your last question的woocommerce_checkout_create_order_line_item取代。
所以在下面，我重新介绍了您的最后3个功能：
// Store custom field label and value in cart item data
add_action( 'woocommerce_add_cart_item_data','add_custom_data_as_custom_cart_item_data', 10, 3 );
function add_custom_data_as_custom_cart_item_data( $cart_item_data, $product_id, $variation_id ) {
if( isset( $_REQUEST['FieldTypeValue1'] ) ) {
// Get an instance of the WC_Product object
$product = wc_get_product( $variation_id > 0 ? $variation_id : $product_id );
if( $label = $product->get_meta('FieldName1') ){
$cart_item_data['custom_data'] = array(
'label' => $product->get_meta('FieldName1'),
'value' => sanitize_text_field( $_REQUEST['FieldTypeValue1'] ),
'unique_key' => md5( microtime().rand() ),
);
}
}
return $cart_item_data;
}
// Display cart item custom data in cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'display_cart_item_custom_on_cart_and_checkout', 10, 2 );
function display_cart_item_custom_on_cart_and_checkout( $cart_item_data, $cart_item ){
if( isset($cart_item['custom_data']['label']) && isset($cart_item['custom_data']['value']) ) {
$cart_item_data[] = array(
'name' => $cart_item['custom_data']['label'],
'value' => $cart_item['custom_data']['value'],
);
}
return $cart_item_data;
}
// Save cart item custom data as order item meta data and display it everywhere in Orders and email notifications
add_action('woocommerce_checkout_create_order_line_item', 'save_custom_order_item_meta_data', 10, 4 );
function save_custom_order_item_meta_data( $item, $cart_item_key, $values, $order ) {
if( isset( $values['custom_data']['label'] ) && isset( $values['custom_data']['value'] ) ) {
$item->update_meta_data( $values['custom_data']['label'], $values['custom_data']['value'] );
}
}
