将自定义交货日期范围计算保存到 WooCommerce 订单元数据

Question

我使用 woocommerce 并编写了一个函数，它根据库存状态显示预期交货的日期范围...
供参考：

现在我想将每个订单的计算日期范围输出到我的管理面板中。

对于 Wordpress 后端中的订单编辑页面，我使用以下代码：

 add_action( 'add_meta_boxes', 'add_meta_boxes' );
function add_meta_boxes() {
    add_meta_box(  'woocommerce-order-my-custom', __( 'Order Custom' ), 
        'order_my_custom', 'shop_order', 'side', 'default' 
    );
}

function order_my_custom(){
  echo "Voraussichtliche Lieferung<br> $from - $to";
}

日期范围使用以下代码计算并显示在前端：

add_filter ( 'woocommerce_cart_collaterals', 'lieferzeit');
add_filter ( 'woocommerce_thankyou_lieferung', 'lieferzeit');
function lieferzeit() {

    $all_items_in_stock = true; // initializing

    // Iterating through cart items (to get the stock info)
    foreach (WC()->cart->get_cart() as $cart_item) {

        # HANDLING SIMPLE AND VARIABLE PRODUCTS

        // Variable products
        $variation_id = $cart_item['variation_id']; 
        if( 0 != $variation_id) {
            $variation_obj = new WC_Product_variation($variation_id);
            $stock = $variation_obj->get_stock_quantity();
        } else { 
            // Simple products
            $product_id = $cart_item['product_id'];
            $product_obj = new WC_Product($product_id);
            $stock = $product_obj->get_stock_quantity();
        }

        if( $stock <= 0 ){
            // if an item is out of stock
            $all_items_in_stock = false;
            break; // We break the loop
        }
    }

    // Items "in stock" (1 to 4 week days)
    if( $all_items_in_stock ){
        for( $start=0, $count=-1 ; $count < 4; $start++ ){
            $weekdays = date('w', strtotime("+$start days"));
            if( $weekdays > 0 && $weekdays < 6 ){
                $count++;
//            echo date('D j (w)', strtotime("+$start days")).', ';
                if($count == 1){
                    $from = date('D, d.m.', strtotime("+$start days") );
                } elseif($count == 4) {
                    $to = date('D, d.m.', strtotime("+$start days") );
                }
            }
        }
    } else { // 1 is Items Out of stock (14 to 21 week days)
        for( $start=0, $count=-1 ; $count < 21; $start++ ){
            $weekdays = date('w', strtotime("+$start days"));
            if( $weekdays > 0 && $weekdays < 6 ){
                $count++;
                if($count == 14){
                    $from = date('D, d.m.', strtotime("+$start days") );
                } elseif($count == 21) {
                    $to = date('D, d.m.', strtotime("+$start days") );
                }
            }
        }
    }

    ## TRANSLATION ##

    // DAYS IN ENGLISH (Source)
    $days_en = array('Mon''Tue','Wed','Thu','Fri');

    // TRANSLATE the DAYS in GERMAN (replacement)
    $days_ge = array('Mo','Di','Mi','Do','Fr');

    $from = str_replace($days_en, $days_ge, $from);
    $to   = str_replace($days_en, $days_ge, $to);

    ## OUTPUT ##
    //    echo "Voraussichtliche Lieferung<br> $from - $to";
    echo '<i class="shipping_icon fa fa-truck fa-flip-horizontal" aria-hidden="true"></i> <div class="lieferung"> Vorauslichtliche Lieferung </div>  <div class="fromto_date"> ' . $from . ' – ' . $to . ' </div> <div class="tooltip">
  <span class="tooltiptext">Gilt nur bei Lieferungen nach Deutschland.</span></div>' ;
}

我的问题是函数 lieferzeit() 的 "estimated delivery range" 数据没有出现在函数 add_meta_boxes() 中。

希望在提交订单时存储"estimated delivery range"数据（函数lieferzeit()），以显示在相应的订单后端metabox中。

如果我尝试在感谢页面中添加函数 lieferzeit() 的输出，它会起作用，但它不会存储数据。

那么如何保存和获取计算的日期愤怒数据以在我需要的任何地方使用它？

谢谢

Answer 1

我建议你给你的函数加上前缀以避免冲突。

例如add_action( 'add_meta_boxes', 'cust_add_meta_boxes' );

It would be great if there was a way to store the output of function lieferzeit() in a way which doesn't change the output anymore.

您可以将其存储为元数据，例如

$order_id = WC()->order->id;
update_post_meta( $order_id, '_lieferzeit_from', $from );
update_post_meta( $order_id, '_lieferzeit_to', $to );

修改函数order_my_custom()为：

function order_my_custom()
{
   global $post;  
   $from = get_post_meta($post->ID, '_lieferzeit_from', true);
   $to = get_post_meta($post->ID, '_lieferzeit_to', true);
   echo "Voraussichtliche Lieferung<br> $from - $to";
}

Answer 2

我对你的代码做了一些小改动。

我已将基于产品库存可用性的所有购物车计算代码嵌入到我可以在任何地方调用的单独函数（非挂钩）中。
我添加和更改了一些钩子：
- 用于显示范围的结帐挂钩
- 一个结帐挂钩，用于添加隐藏输入字段，具有 $from 和 $to 值，以post提交订单时的数据。
- 将在订单元数据中保存送货范围数据的挂钩

因此您的代码将是：

// The function that calculate the delivery dates range (Not hooked)
function calculate_delivery_range() { 

    $all_items_in_stock = true; // initializing

    // Iterating through cart items (to get the stock info)
    foreach (WC()->cart->get_cart() as $cart_item) {

        # HANDLING SIMPLE AND VARIABLE PRODUCTS

        // Variable products
        $variation_id = $cart_item['variation_id'];
        if( 0 != $variation_id) {
            $variation_obj = new WC_Product_variation($variation_id);
            $stock = $variation_obj->get_stock_quantity();
        } else {
            // Simple products
            $product_id = $cart_item['product_id'];
            $product_obj = new WC_Product($product_id);
            $stock = $product_obj->get_stock_quantity();
        }

        if( $stock <= 0 ){
            // if an item is out of stock
            $all_items_in_stock = false;
            break; // We break the loop
        }
    }

    // Items "in stock" (1 to 4 week days)
    if( $all_items_in_stock ){
        for( $start=0, $count=-1 ; $count < 4; $start++ ){
            $weekdays = date('w', strtotime("+$start days"));
            if( $weekdays > 0 && $weekdays < 6 ){
                $count++;
//            echo date('D j (w)', strtotime("+$start days")).', ';
                if($count == 1){
                    $from = date('D, d.m.', strtotime("+$start days") );
                } elseif($count == 4) {
                    $to = date('D, d.m.', strtotime("+$start days") );
                }
            }
        }
    } else { // One or more Items are Out of stock (14 to 21 week days)
        for( $start=0, $count=-1 ; $count < 21; $start++ ){
            $weekdays = date('w', strtotime("+$start days"));
            if( $weekdays > 0 && $weekdays < 6 ){
                $count++;
                if($count == 14){
                    $from = date('D, d.m.', strtotime("+$start days") );
                } elseif($count == 21) {
                    $to = date('D, d.m.', strtotime("+$start days") );
                }
            }
