我在 woocommerce（最新版本）中的自定義字段有問題。我需要你的幫助。我的代碼function completed_order($order_id) { $order = wc_get_order( $order_id ); $customer_id = $order->get_customer_id(); $user = get_user_by('id', $customer_id); foreach ( $order->get_items() as $item_id => $item ) { $validity = $item->get_meta( 'validity_field' ); if($validity) { $a = get_post_meta($item->get_id(), 'validity_field', true); } } }add_action('woocommerce_order_status_completed', 'completed_order', 10, 1);function create_custom_field() { $args = array( 'id' => 'validity_field', 'label' => __( 'Wa?no?? konta', 'waznosc' ), 'class' => 'waznosc-custom-field', 'desc_tip' => true, 'description' => __( 'Wprowadz ilosc dni waznosci konta', 'waznosc' ), ); woocommerce_wp_text_input( $args );}add_action( 'woocommerce_product_options_general_product_data', 'create_custom_field' );function save_custom_field( $post_id ) { $product = wc_get_product( $post_id ); $title = isset( $_POST['validity_field'] ) ? $_POST['validity_field'] : ''; $product->update_meta_data( 'validity_field', sanitize_text_field( $title ) ); $product->save();}add_action( 'woocommerce_process_product_meta', 'save_custom_field' );function add_custom_data_to_order( $item, $cart_item_key, $values, $order ) { foreach( $item as $cart_item_key=>$values ) { if( isset( $values['title_field'] ) ) { $item->add_meta_data( __( 'Waznosc konta', 'waznosc' ), $values['validity_field'], true ); } }}add_action( 'woocommerce_checkout_create_order_line_item', 'add_custom_data_to_order', 10, 4 );現在我在從自定義字段獲取數據時遇到問題validity_field。字段被保存到數據庫，因為當我編輯產品時值在字段中，但在完成訂單后我無法將其掛鉤:(我嘗試使用 get_post_meta、get_meta 和其他方法，但沒有任何作用。有人知道原因嗎？

您的代碼中有一些錯誤。請嘗試以下操作：
add_action( 'woocommerce_product_options_general_product_data', 'add_admin_product_custom_field' );
function add_admin_product_custom_field() {
woocommerce_wp_text_input( array(
'id' => 'validity_field',
'label' => __( 'Wa?no?? konta', 'waznosc' ),
'class' => 'waznosc-custom-field',
'desc_tip' => true,
'description' => __( 'Wprowadz ilosc dni waznosci konta', 'waznosc' ),
) );
}
add_action( 'woocommerce_admin_process_product_object', 'save_product_custom_field_value' );
function save_product_custom_field_value( $product ) {
$value = isset( $_POST['validity_field'] ) ? sanitize_text_field($_POST['validity_field']) : '';
$product->update_meta_data( 'validity_field', $value );
}
add_action( 'woocommerce_checkout_create_order_line_item', 'add_custom_data_to_order_item', 10, 4 );
function add_custom_data_to_order( $item, $cart_item_key, $values, $order ) {
$product = wc_get_product( $item->get_product_id() ); // The WC_Product Object (and the parent variable product object for product variations)
$value = $product->get_meta('validity_field');
if( ! empty( $value ) ) {
$item->update_meta_data( __( 'Waznosc konta', 'waznosc' ), $value );
}
}
add_action( 'woocommerce_order_status_completed', 'action_completed_order', 10, 2 );
function action_completed_order( $order_id, $order ) {
$user_id = $order->get_customer_id();
$user = $order->get_user(); // The WP_User Object (if needed)
foreach ( $order->get_items() as $item_id => $item ) {
$validity = $item->get_meta( 'validity_field' );
if ( ! empty($validity) ) {
// Do something with $validity
}
}
}
這次應該可以了。
