我很难将我的自定义字段值打印到电子邮件通知、订单管理和感谢页面。我浏览了 StackOverflow，尝试了我找到的每一个答案，但不幸的是没有工作，我无法解决问题：我试图传递附加结帐字段的值，它只打印带有空白值的强标签，并且在电子邮件中没有显示任何内容，这是我到目前为止的代码：
//new pickup location checkout field
add_action( 'woocommerce_before_order_notes', 'pickup_location_custom_checkout_field' );
function pickup_location_custom_checkout_field( $checkout ) {
echo '<div><h3>' . __('Pick-up location') . '</h3>';
woocommerce_form_field( 'pick_up_location', array(
'type' => 'text',
'class' => array('notes'),
'label' => __('<span style="color:red">[IMPORTANT]</span> Where should we meet you?'),
'placeholder' => __('Please enter your accomodation name or the nearest pick-up point if not accessible by car'),
'required' => true,
), $checkout->get_value( 'pick_up_location' ));
echo '</div>';
}
// Save the pickup location data to the order meta
add_action( 'woocommerce_checkout_create_order', 'pickup_location_checkout_field_update_order_meta' );
function pickup_location_checkout_field_update_order_meta( $order_id ) {
if (!empty($_POST['pick_up_location'])) {
update_post_meta( $order_id, 'Pick-up location', sanitize_text_field( $_POST['pick_up_location']));
}
}
// Display 'pickup location' on the order edit page (backend)
add_action( 'woocommerce_admin_order_data_after_shipping_address', 'pickup_location_checkout_field_order_page', 10, 1 );
function pickup_location_checkout_field_order_page($order){
global $post_id;
$order = new WC_Order( $post_id );
echo '<p><strong style="color:red">'.__('Pickup Location').':</strong> ' . get_post_meta($order->get_id(), '_pick_up_location', true ) . '</p>';
// Display 'pickup location' in "Order received" and "Order view" pages (frontend)
add_action( 'woocommerce_order_details_after_order_table', 'display_client_pickup_data_in_orders', 10 );
function display_client_pickup_data_in_orders( $order ) {
global $post_id;
$order = new WC_Order( $post_id );
echo '<p><strong style="color:red">'.__('Pickup Location').':</strong> ' . get_post_meta($order->get_id(), '_pick_up_location', true ) . '</p>';
}
// Display 'pickup location data' in Email notifications
add_filter( 'woocommerce_email_order_meta_fields', 'display_client_pickup_data_in_emails', 10, 3 );
function display_client_pickup_data_in_emails( $fields, $sent_to_admin, $order ) {
$fields['Pickup Location'] = array(
'label' => __( 'Pickup Location' ),
'value' => get_post_meta( $order->get_id(), 'pick_up_location', true ),
);
return $fields;
}
无论我尝试什么，代码只会打印标签，而结帐表单中没有任何值。我知道这个问题已经被问过很多次了，但是我尝试了每一个答案超过 6 天，但没有任何运气。我还需要提到我在这个项目中使用 Woocommerce Bookings。谢谢你的帮助
[更新：]在购物车、管理员订单、客户订单、结帐和电子邮件中保存和显示 ACF 字段。感谢@7uc1f3r的详细解释，他的回答帮助我以类似的方式显示ACF字段，它也是基于来自@LoicTheAztec的This answer 。
在 ATC 上方的产品页面上显示自定义字段：
// Displaying Pick-up time custom field value in single product page
add_action( 'woocommerce_before_add_to_cart_button', 'add_pickup_time_custom_field', 0 );
function add_pickup_time_custom_field() {
global $product;
//(compatibility with WC +3)
$product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;
echo "<div class='pickup-time-atc'>";
echo "<span>Pick-up time: </span>";
echo get_field( 'pick_up_time', $product_id );
echo "</div>";
return true;
}
将取货时间自定义字段保存到购物车和会话中
// Saving Pick-up time custom field into cart and session
add_filter( 'woocommerce_add_cart_item_data', 'save_pickup_time_custom_field', 10, 2 );
function save_pickup_time_custom_field( $cart_item_data, $product_id ) {
$custom_field_value = get_field( 'pick_up_time', $product_id, true );
if( !empty( $custom_field_value ) )
{
$cart_item_data['pick_up_time'] = $custom_field_value;
}
return $cart_item_data;
}
在购物车和结帐时呈现提货时间自定义字段元
// Render Pick-up time meta on cart and checkout
add_filter( 'woocommerce_get_item_data', 'render_pickuptime_meta_on_cart_and_checkout', 10, 2 );
function render_pickuptime_meta_on_cart_and_checkout( $cart_data, $cart_item ) {
$custom_items = array();
// Woo 2.4.2 updates
if( !empty( $cart_data ) ) {
$custom_items = $cart_data;
}
if( isset( $cart_item['pick_up_time'] ) ) {
$custom_items[] = array( "name" => "Pickup time", "value" => $cart_item['pick_up_time'] );
}
return $custom_items;
}
添加自定义字段元以订购管理员详细信息
// Add pickup time custom field meta to order admin
add_action( 'woocommerce_checkout_create_order_line_item', 'pickuptime_checkout_create_order_line_item', 10, 4 );
function pickuptime_checkout_create_order_line_item( $item, $cart_item_key, $values, $order ) {
if( isset( $values['pick_up_time'] ) ) {
$item->add_meta_data(
__( 'Pickup time' ),
$values['pick_up_time'],
true
);
}
}
将取件时间自定义字段元添加到电子邮件
// Add pickup time custom field meta to emails
add_filter( 'woocommerce_order_item_name', 'pickuptime_order_item_emails', 10, 2 );
function pickuptime_order_item_emails( $product_name, $item ) {
if( isset( $item['pick_up_time'] ) ) {
$product_name .= sprintf(
'<ul"><li>%s: %s</li></ul>',
__( '<span style="color:red !important">Pickup time</span>' ),
esc_html( $item['pick_up_time'] )
);
}
return $product_name;
}
