Php 回声多回路结构中的堆栈

这是我从数据库中回显内容的php代码

<?php
include ("config.php");
$results = $mysqli->query
("SELECT transaction_id FROM orders_list WHERE customer_name = 'Klaudia' ORDER BY id LIMIT 100");           
if ($results) {
    while($obj = $results->fetch_object()) {
        echo '<div id="thisklop">';
        echo '<ul class="ulung">Id_cart';           
        echo '<li>'.$obj->transaction_id.'</li>';
        echo '</ul>';
                $thisthat=$obj->transaction_id;         
                $otherresults = $mysqli->query
                            ("SELECT transaction_id, items, quantity, one_product_price FROM orders_history
                              WHERE transaction_id = '$thisthat'");         
                if ($otherresults) {
                    while($obj = $otherresults->fetch_object()) {
                        echo '<div>';
                        echo '<ul class="ulung">Products';
                        echo '<li>'.$obj->items.'</li>';
                        echo '</ul>';
                        echo '</div><br>';

                        echo '<div>';
                        echo '<ul class="ulung">Quantity';
                        echo '<li>'.$obj->quantity.'</li>';
                        echo '</ul>';
                        echo '</div><br>';

                        echo '<div>';
                        echo '<ul class="ulung">Invoices';
                        echo '<li>'.$obj->one_product_price.'</li>';
                        echo '</ul>';
                        echo '</div><br>';
                    }
                }                                       
        echo '</div>';
    }
}
?>

从上表中可以看出，id_购物车处于循环中，然后在id_购物车中还有处于循环中的内容

我被困在结构上，我在呼应它。建筑物乱七八糟

首先，在一个查询中更快地获取所有数据，然后首先在数组中收集数据。最后，根据数组构造输出：

<?php
include ("config.php");
$results = $mysqli->query
("
    SELECT  DISTINCT    orders_history.transaction_id,
                        orders_history.items,
                        orders_history.quantity,
                        orders_history.one_product_price
    FROM                orders_history, orders_list
    WHERE               orders_history.transaction_id = orders_list.transaction_id
    AND                 orders_list.customer_name = 'Klaudia'"

);

$orders = array();     
$html = '';     
if ($results) {
    while($obj = $results->fetch_object()) {
        $orders[$obj->transaction_id][$obj->items] = array('quantity' => $obj->quantity, 'invoices' => $obj->one_product_price);
    }

        $html .= '<table><tr>';
        $html .= '<th>id_cart</th>';
        $html .= '<th>products</th>';
        $html .= '<th>quantity</th>';
        $html .= '<th>invoices</th></tr>';
        foreach ($orders AS $order_id => $order) {
            $html .= '<tr><td rowspan="' . count($order) . '">' . $order_id . '</td>';
            $row = 1;
            foreach ($order AS $item => $data) {
                if ($row > 1) { $html .= '</tr><tr>'; }
                $html .= '<td>' . $item . '</td>';
                $html .= '<td>' . $data['quantity'] . '</td>';
                $html .= '<td>' . $data['invoices'] . '</td>';
/* INSERTED CODE FOR STATUS */
                if ($row == 1) {
                  $html .= '<tr><td rowspan="' . count($order) . '">' . $status . '</td>';
                }
/* END OF INSERTION */
                $row++;
            }
            $html .= '</tr>';
        }
        $html .= '</table>';
    } 
    echo $html;
    ?>

注意：这是我头脑中写的未经测试的，可能有一些错误，但主路径应该是清晰的。

你是说卡住了，不是堆栈？你收到任何错误消息了吗？能否在$orders=array之前发布var_dump$results insert的结果；行？当我将它更改为打印\r$结果时，它只是打印布尔法尔斯；它也没有显示任何东西，我只是解决了它。但我还需要更多。我想计算总价格，然后在发票底部显示它。我需要的只是如何将其放入表中，因为我可以从表中的另一行列中获取数据。例如：对于每个id_购物车，总计=60.000。查看问题中上面的更新表，我还希望id_cart的每个结果都被包装，这样我就可以在每个单独的块上设置边框样式，看起来与上面的示例相同。帮助
