如何从客户电子邮件和订单中的 select 字段获取 order_meta 详细信息？

Question

很高兴知道：我根据产品的数量创建了额外的字段。因此，如果有人两次购买该产品，他必须在结账时填写两个字段。如果有人购买产品 1x，他们必须填写一次该字段。

这些额外字段包含“select 选项”。我需要在我的订单概览和来自 woocommerce 的电子邮件中获取元数据。

您可以使用 woocommerce_email_order_meta 操作挂钩将自定义元数据添加到电子邮件中，并使用 woocommerce_admin_order_data_after_order_details 挂钩在概览页面上显示自定义元数据。试试下面的代码。

function person_details( $checkout ) {

    global $woocommerce;
    $count = $woocommerce->cart->cart_contents_count;
    $i = 0;

    for( $k=1; $k<= $count; $k++ ) {
        $i++;
        print ('Gegevens van kind '.$i.'');
        
        woocommerce_form_field( 'cstm_full_name'.$i, array(
            'type'          => 'text',
            'class'         => array('my-field-class form-row-wide'),
            'label'         => __('Volledige naam'),
            'placeholder'   => __(''),
            'required' => true,
        ), $checkout->get_value( 'cstm_full_name'.$i ));
        
        echo '<div class="clear"></div>';
        
            woocommerce_form_field( 'cstm_gender'.$i, array(
                'type'          => 'select',
                'required' => true,
