Question

我正在尝试循环行以回显我的结果。因此，我将加入2个数据库表以获取一些结果，特别是来自orders表的型号和型号名称，而其他结果来自order_history表。我正在尝试使行循环，以使其回显在什么时间，由谁以及由谁批准的货物。但是，我似乎得到了无穷无尽的结果循环，请问如何对结果进行循环。这些是我正在使用的表-> orders table和order_history table。谢谢。

Answer 1

使用以下内容：-

<?php while($rows = $result->fetch_assoc()){ ?>
<tr>
<td> <?php echo $rows['order_id'];  ?> </td>
<td> <?php echo $rows['model_number'];  ?> </td>
<td> <?php echo $rows['model_name'];  ?> </td>
<td align="center"> 
    <ul>
        <li>Delivered by <?php echo $rows['deliverer'];  ?> at 
            <?php echo $rows['time_delivered'];  ?></li>
        <li><?php echo $rows['order_status'];  ?> by <?php echo $rows['approver'];  ?></li>
    </ul>
</td>
<td align="center"> 
    <ul>
        <li>Delivered by <?php echo $rows['deliverer'];  ?> at <?php echo $rows['time_delivered'];  ?></li>
        <li><?php echo $rows['order_status'];  ?> by <?php echo $rows['approver'];  ?></li>
   </ul>
</td>
</tr>
<?php } ?>

循环输出结果
