将自定义字段数据添加到 WooCommerce 订单 [英] Add custom field data to WooCommerce order
问题描述
我的 WooCommerce 单一产品上有一个自定义字段.它发送到购物车罚款，它在结帐时显示，它在仪表板中按顺序显示.
I have a custom field on my WooCommerce single product. It sends to the cart fine, it displays on checkout fine, it shows in the order in the dashboard fine.
我现在要做的是将值设置为订单页面中的自定义字段，这样我就可以在需要时修改文本.出于某种原因，当我提交表单时，这一步不起作用.
What I am now trying to do is set the value as a custom field in the order page so I am able to amend the text when I need to. For some reason when I submit the form this step isn't working.
我在functions.php文件中使用的代码:
The code that i use in my functions.phpfile:
// Add the field to the product
add_action('woocommerce_before_add_to_cart_button', 'my_custom_checkout_field');
function my_custom_checkout_field() {
echo '<div id="my_custom_checkout_field"><h3>'.__('My Field').'</h3>';
echo '<label>fill in this field</label> <input type="text" name="my_field_name">';
echo '</div>';
}
// Store custom field
function save_my_custom_checkout_field( $cart_item_data, $product_id ) {
if( isset( $_REQUEST['my_field_name'] ) ) {
$cart_item_data[ 'my_field_name' ] = $_REQUEST['my_field_name'];
/* below statement make sure every add to cart action as unique line item */
$cart_item_data['unique_key'] = md5( microtime().rand() );
}
return $cart_item_data;
}
add_action( 'woocommerce_add_cart_item_data', 'save_my_custom_checkout_field', 10, 2 );
// Render meta on cart and checkout
function render_meta_on_cart_and_checkout( $cart_data, $cart_item = null ) {
$custom_items = array();
/* Woo 2.4.2 updates */
if( !empty( $cart_data ) ) {
$custom_items = $cart_data;
}
if( isset( $cart_item['my_field_name'] ) ) {
$custom_items[] = array( "name" => 'My Field', "value" => $cart_item['my_field_name'] );
}
return $custom_items;
}
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );
// Display as order meta
function my_field_order_meta_handler( $item_id, $values, $cart_item_key ) {
if( isset( $values['my_field_name'] ) ) {
wc_add_order_item_meta( $item_id, "my_field_name", $values['my_field_name'] );
}
}
add_action( 'woocommerce_add_order_item_meta', 'my_field_order_meta_handler', 1, 3 );
/** THIS IS WHERE I'M STUCK **/
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');
function my_custom_checkout_field_process() {
global $woocommerce;
// Check if set, if its not set add an error. This one is only requite for companies
if ($_POST['billing_company'])
if (!$_POST['my_field_name'])
$woocommerce->add_error( __('Please enter your XXX.') );
}
// Update the user meta with field value
add_action('woocommerce_checkout_update_user_meta', 'my_custom_checkout_field_update_user_meta');
function my_custom_checkout_field_update_user_meta( $user_id ) {
if ($user_id && $_POST['my_field_name']) update_user_meta( $user_id, 'my_field_name', esc_attr($_POST['my_field_name']) );
}
// Update the order meta with field value
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ($_POST['my_field_name']) update_post_meta( $order_id, 'My Field', esc_attr($_POST['my_field_name']));
}

推荐答案
更新:与 Woocommerce 版本 3+ 的兼容性
Updated: compatibility with Woocommerce version 3+
您缺少在订单编辑页面上显示此自定义字段值的功能:
You have missing the function to display this custom field value on the order edit page:
/**
* Display field value on the order edit page
*/
add_action( 'woocommerce_admin_order_data_after_billing_address', 'my_custom_checkout_field_display_admin_order_meta', 10, 1 );
function my_custom_checkout_field_display_admin_order_meta( $order ){
$order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;
echo '<p><strong>'.__('My Field Name').':</strong> ' . get_post_meta( $order_id, 'my_field_name', true ) . '</p>';
}
