在购物车、结账、订单和电子邮件通知中显示WooCommerce自定义产品字段元数据

Question

我创建了一个自定义产品字段(admin(。该字段工作良好，保存数据也很好。

我遇到的问题是将元数据添加到购物车并结账。

我没有收到任何错误(调试在wp-config中打开(，没有任何通知——什么都没有。在购物车和结账时，不会显示任何数据。

这是我的代码：

add_action( 'woocommerce_product_options_general_product_data', 'product_delivery_time' );
function product_delivery_time(){
global $woocommerce, $post;
echo '<div class="product_custom_field">';
woocommerce_wp_text_input(
array(
'id' => '_shipping_field',
'placeholder' => 'shipping time in days',
'label' => __('Shipping Time', 'woocommerce'),
'desc_tip' => 'true'
)
);
echo '</div>';
}
add_action( 'woocommerce_process_product_meta', 'product_delivery_time_save' );
function product_delivery_time_save( $post_id ) {
if (isset($_POST['_shipping_field'] ) )
update_post_meta( $post_id, '_shipping_field', esc_attr( $_POST['_shipping_field'] ) );
}
add_filter( 'woocommerce_add_cart_item_data', 'delivery_time_in_cart', 10, 3 ); 
function delivery_time_in_cart( $cart_item_data, $product_id, $variation_id ) {
if (! empty( $_POST['_shipping_field'] ) ) {
$cart_item_data['_shipping_field'] = sanitize_text_field( $_POST['_shipping_field'] );
}

return $cart_item_data;
}
add_filter( 'woocommerce_get_item_data', 'delivery_time_in_cart_display', 10, 2 ); 
function delivery_time_in_cart_display( $item_data, $cart_item ) {
if (! empty($cart_item['_shipping_field'] ) ) {
$item_data[] = array(
'key' => '_shipping_field',
'value' => $cart_item['_shipping_field'],
'display' => '',
);
}

return $item_data;
}
add_action( 'woocommerce_checkout_create_order_line_item', 'delivery_time_in_order_display', 10, 4 ); 
function delivery_time_in_order_display( $item, $cart_item_key, $values, $order ) {
if (! empty($values['_shipping_field'] ) ) {
$item->add_meta_data( 'Delivery time:', $values['_shipping_field'] );
}
}

您有一些小错误，这应该足够了

• 注意使用woocommerce_admin_process_product_object进行保存，而不是过时的woocommerce_process_product_meta挂钩

所以你得到

// Add field
function product_delivery_time() {
echo '<div class="product_custom_field">';
woocommerce_wp_text_input( array(
'id' => '_shipping_field',
'placeholder' => 'shipping time in days',
'label' => __('Shipping Time', 'woocommerce'),
'desc_tip' => 'true'
)
);
echo '</div>';
}
add_action( 'woocommerce_product_options_general_product_data', 'product_delivery_time', 10, 0 );
// Save Field
function woo_add_custom_general_fields_supplier_save( $product ) {
if( isset($_POST['_shipping_field']) ) {
$product->update_meta_data( '_shipping_field', esc_html( $_POST['_shipping_field'] ) );
}
}
add_action( 'woocommerce_admin_process_product_object', 'woo_add_custom_general_fields_supplier_save', 10, 1 );
// Display on cart & checkout pages
function delivery_time_in_cart_display( $item_data, $cart_item ) {
$shipping_field = $cart_item['data']->get_meta('_shipping_field');

if ( ! empty( $shipping_field ) ) {
$item_data[] = array(
'name' => __('Shipping field', 'woocommerce'),
'value' => $shipping_field,
);
}

return $item_data;
}
add_filter( 'woocommerce_get_item_data', 'delivery_time_in_cart_display', 10, 2 );
// Display item data everywhere on orders and email notifications 
function delivery_time_in_order_display( $item, $cart_item_key, $values, $order ) {
$shipping_field = $values['data']->get_meta('_shipping_field');
if ( ! empty( $shipping_field ) ) {
$item->update_meta_data( __( 'Shipping field', 'woocommerce'), $shipping_field );
}
}
add_action( 'woocommerce_checkout_create_order_line_item', 'delivery_time_in_order_display', 10, 4 );
