Question

我正在尝试为WooCommerce插件中的所有已完成订单显示所有订单商品（包含Item Meta）。我还想将显示限制为仅10个订单商品。我已经想出如何显示所有订单商品但不能将数量限制为10.以下是我目前用于显示所有订单商品的代码：

$args = array(
                    'post_type' => 'shop_order',
                    'post_status' => 'publish',
                    'posts_per_page' => -1,
                    'tax_query' => array(
                        array(
                            'taxonomy' => 'shop_order_status',
                            'field' => 'slug',
                            'terms' => array('completed')
                        )
                    )
                );

                $loop = new WP_Query( $args );

                while ( $loop->have_posts() ) : $loop->the_post();
                    $order_id = $loop->post->ID;
                    $order = new WC_Order($order_id);

                    foreach( $order->get_items() as $item ) {   

                        $date = $item['Booking Date'];
                        $time = $item['Booking Time'];
                        $fname = $item['First Name - First Name'];
                        $church = $item['Church Information - Church Name'];
                        $city = $item['Church Information - City'];
                        $state = $item['Church Information - State'];
                    ?>

                        <div class="wc-upcoming-booking">
                            <div class="wc-upcoming-time">
                                <span class="upcoming-hour"><?php echo $time; ?></span>
                                <span class="upcoming-date"><?php echo $date; ?></span>
                            </div>
                            <div class="wc-upcoming-details">
                                <?php echo $fname . ', ' . $church . ', ' . $city . ', ' . $state; ?>
                            </div>
                        </div>

                    <?php }

                endwhile;

此代码查询所有已完成的订单，然后循环查看每个查询订单的所有订单项。某些订单可能包含多个订单商品，因此如果我将每页订单限制为10并且所有订单都有5个订单商品，那么我将显示总共50个订单商品。我尝试在foreach循环中添加一个“iterate”变量来限制它，但是只循环一个Order的“5”订单项而不是总共“50”订单项。

首先，我需要通过$ date和$ time变量对所有订单项进行排序（我相信我可以通过使用strtotime（）函数将它们转换为时间戳来实现）。

其次，我想在所有订单中只显示前10个订单项（基于时间戳）。

任何想法如何修改此代码以实现此目的？

这样的事情应该将显示的项目数限制为10：

<?php
$args = array(
    'post_type' => 'shop_order',
    'post_status' => 'publish',
    'posts_per_page' => 10,
    'tax_query' => array(
        array(
            'taxonomy' => 'shop_order_status',
            'field' => 'slug',
            'terms' => array('completed')
        )
    )
);
$orders=get_posts($args);
$i=0;
foreach($orders as $o):
    if($i>10){
        break;
    }
    $order_id = $o->ID;
    $order = new WC_Order($order_id);
    foreach( $order->get_items() as $item ):
        if($i>10){
            break;
        }
        $i++;
        $date = $item['Booking Date'];
        $time = $item['Booking Time'];
        $fname = $item['First Name - First Name'];
        $church = $item['Church Information - Church Name'];
        $city = $item['Church Information - City'];
        $state = $item['Church Information - State'];
    ?>
        <div class="wc-upcoming-booking">
            <div class="wc-upcoming-time">
                <span class="upcoming-hour"><?php echo $time; ?></span>
                <span class="upcoming-date"><?php echo $date; ?></span>
            </div>
            <div class="wc-upcoming-details">
                <?php echo $fname . ', ' . $church . ', ' . $city . ', ' . $state; ?>
            </div>
        </div>
    <?php endforeach;
endforeach;?>

如果我理解你正确寻找的东西应该可以解决问题。

我不认为wordpress会为您提供此类查询。你必须建立自己的逻辑来做到这一点。希望这可以帮助你...

$args = array(
   'post_type' => 'shop_order',
   'post_status' => 'publish',
   'posts_per_page' => -1,
   'tax_query' => array(
       array(
            'taxonomy' => 'shop_order_status',
            'field' => 'slug',
            'terms' => array('completed')
            )
          )
   );

         $count = 0;
         $loop = new WP_Query( $args );

            while ( $loop->have_posts() ) : $loop->the_post();
                $order_id = $loop->post->ID;
                $order = new WC_Order($order_id);

                foreach( $order->get_items() as $item ) {   

                    if( $count > 10){
                       break 2; //break both loops 
                    } 
                    $count++;
                    $date = $item['Booking Date'];
                    $time = $item['Booking Time'];
                    $fname = $item['First Name - First Name'];
                    $church = $item['Church Information - Church Name'];
                    $city = $item['Church Information - City'];
                    $state = $item['Church Information - State'];
                ?>

                    <div class="wc-upcoming-booking">
                        <div class="wc-upcoming-time">
                            <span class="upcoming-hour"><?php echo $time; ?></span>
                            <span class="upcoming-date"><?php echo $date; ?></span>
                        </div>
                        <div class="wc-upcoming-details">
                            <?php echo $fname . ', ' . $church . ', ' . $city . ', ' . $state; ?>
                        </div>
                    </div>

                <?php }

            endwhile;
