问题描述
我有一些自定义代码可以正常工作，并且由于我已经将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.
I have some custom code was working perfectly and since I have updated Woocommerce to version 3.5.2 it is not working anymore, not sure if it is because I changed the wordpress theme or because because plugin updates.
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.
My problem is that the value of the custom fields doesn't appear on the order page from woocommerce or even on the order email.
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.
I have been looking for hours and i have no idea how to solve it or what the problem is. Any help or tips will be really helpful. Thanks a lot.
推荐答案
第一个主要问题是 $ cart_item_data ['custom_data'] ['1'] = array(应该是:
The first main problem is $cart_item_data['custom_data']['1'] = array( that should be instead:
$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，并已由 woocommerce_checkout_create_order_line_item 代替，已经回答了
Then the 2nd main problem is the last function where woocommerce_get_item_data is obsolete and replaced by woocommerce_checkout_create_order_line_item already answered in your last question.
所以在下面，我重新介绍了您的最后3个功能:
So here below I have revisited your 3 last functions:
// 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'] );
}
}
代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试和工作.
Code goes in function.php file of your active child theme (or active theme). Tested and work.
