在一个woocommerce单页产品上,我创建了一个自定义字段。当订单被验证时,我希望它的值被存储在订单元中。经过几个小时的研究,我还没有找到任何解决方案!但我相信我已经很接近它了...
下面是我的实际代码:

// create the custom field
  add_action( 'woocommerce_before_add_to_cart_button', 'add_fields_before_add_to_cart', 100 );
  function add_fields_before_add_to_cart($post) {
    ?>
    <select class="selectpicker" name="premiere_box_abo" id="premiere_box_abo">
      <option value="Septembre 2018">Septembre 2018</option>
      <option value="Octobre 2018">Octobre 2018</option>        
    </select>
    <?php
  }

  // Store custom field
  function save_my_custom_checkout_field( $cart_item_data, $product_id ) {
    if( isset( $_POST['premiere_box_abo'] ) ) {
      $cart_item_data[ 'premiere_box_abo' ] = $_POST['premiere_box_abo'];
      /* 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['premiere_box_abo'] ) ) {
      $custom_items[] = array( "name" => '1e box abonnement', "value" => $cart_item['premiere_box_abo'] );
    }
    return $custom_items;
  }
  add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );

  // Display as order meta
  add_action( 'woocommerce_add_order_item_meta', 'my_field_order_meta_handler', 1, 3 );
  function my_field_order_meta_handler( $item_id, $values ) {
    if( isset( $values['premiere_box_abo'] ) ) {
      wc_add_order_item_meta( $item_id, "1e box abonnement", $values['premiere_box_abo'] );
    }
  }

 // 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 ( ! empty( $_POST['premiere_box_abo'] ) ) {
        update_post_meta( $order_id, 'premiere_box_abo', sanitize_text_field( $_POST['premiere_box_abo'] ) );
   }
  }

以下是我目前所掌握的:

这就是我想要的:

我如何保存这个自定义字段数据为订单元数据,使出现在"自定义字段"元框的值。
任何帮助都很感激。

从woocommerce 3开始,你的代码有点过时,有小错误。
另外,为了回答您的主要问题,您正在尝试将一些“项目”数据保存为订单 meta数据,这不是最好的做法,因为您可以为一个订单保存许多项目。
我重新访问了您的代码如下:

// Display a custom select field below add to cart
add_action( 'woocommerce_before_add_to_cart_button', 'add_field_before_add_to_cart', 10 );
function add_field_before_add_to_cart() {
    global $product;
    ?>
    <select class="selectpicker" name="premiere_box_abo" id="premiere_box_abo">
        <option value="Septembre 2018">Septembre 2018</option>
        <option value="Septembre 2018">Octobre 2018</option>
    </select>
    <?php
}

// Add select field value as custom cart item data
add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_custom_data', 20, 2 );
function add_cart_item_custom_data( $cart_item_data, $product_id ) {
    if( isset( $_POST['premiere_box_abo'] ) ) {
        $cart_item_data['custom_data'] = esc_attr($_POST['premiere_box_abo']);
        $cart_item_data['unique_key'] = md5( microtime().rand() );
    }
    return $cart_item_data;
}

// Display custom cart item data in cart and checkout
add_filter( 'woocommerce_get_item_data', 'display_custom_cart_item_data', 20, 2 );
function display_custom_cart_item_data( $cart_item_data, $cart_item ) {
    if( isset( $cart_item['custom_data'] ) ) {
        $cart_item_data[] = array(
            'name' => __('1e box abonnement'),
            'value' => $cart_item['custom_data']
        );
    }
    return $cart_item_data;
}

// Save / Display custom field value as custom order item meta data
add_action( 'woocommerce_checkout_create_order_line_item', 'custom_field_update_order_item_meta', 20, 4 );
function custom_field_update_order_item_meta( $item, $cart_item_key, $values, $order ) {
    if( isset($values['custom_data']) ){
        $item->update_meta_data( __('1e box abonnement'), $values['custom_data'] );
    }
}

// Save custom fields values as custom order meta data
add_action( 'woocommerce_checkout_create_order', 'my_custom_checkout_field_update_order_meta', 20, 2 );
function my_custom_checkout_field_update_order_meta( $order, $data ) {
    $premiere_box_abo = array();

    // Loop through order items
    foreach( $order->get_items() as $item ){
        // Set each order item '1e box abonnement' in an array
        $premiere_box_abo[] = $item->get_meta( __('1e box abonnement') );
    }
    // Save the data as a coma separated string in order meta data
    if( sizeof($premiere_box_abo) > 0 )
        $order->update_meta_data( 'premiere_box_abo', implode( ',', $premiere_box_abo ) );
}
