php - 如何在用户点击注册号时显示所有维护历史

Question

我想在用户点击注册号时显示所有车辆维修历史记录。但是，当用户点击注册号时，页面只显示最新的数据。例如，TAC 2123有5条维修记录，但当用户选择注册号时，它只显示最新记录的详细信息。如何让它显示所有TAC 2123维修记录？

这是用户选择注册号的代码:

<table width="250" cellspacing="1" cellpadding="1" border="1" align="center">
<tr>
<td>No</td>
<td>Registration No</td>


</tr>
<?php
     $count = 0;
     $db = mysql_connect('localhost','root') 
     or die ("unable to connect");

    mysql_select_db('fyp',$db) or die ("able to select");
    $sql="SELECT * FROM vehicle_record WHERE faculty ='City Campus'";
     $result = mysql_query($sql) or die ("Query failed!");
    while($row = mysql_fetch_array($result)){
       $count = $count + 1;
?>
<tr>
<td><?php echo $count; ?></td>
<td><a href="man_his_details.php?regis=<?php echo $row['regno']; ?>"><?php echo $row['regno']; ?></a></td>  
</tr>
<?php                    
         }
      mysql_close($db);
?>
</table> 


and here's the code to list all the maintenance record based on the selected registration number:

<table width="990" cellspacing="1" cellpadding="1" border="1" align="center">
<tr>
<td>No</td>
<td>Maintenance Date</td>
<td>Maintenance Detail</td>
<td>Last Mileage</td>
<td>Next Change (Mileage)</td>
<td>Warranty</td>
<td>Cost</td>
<td>Driver Name</td>

</tr>
<?php

     $count = 0;
if(isset($_GET['regis']))
        $regno = $_GET['regis'];
    elseif(isset($_POST['regis']))
        $regno = $_POST['regis'];
    else
        $regno = "";

    $db = mysql_connect('localhost','root') 
    or die ("unable to connect");
    mysql_select_db('fyp',$db) or die ("able to select");

$sql_select = "SELECT * FROM maintenance WHERE regno ='".$regno."' ";
                    //. " WHERE `regno`='".($regno)."'";
        //die($sql_select);
    $result = mysql_query($sql_select) or die ("Query failed!");
     $row = mysql_fetch_array($result);
     extract($row);
     //die($sql_select);
     $count = $count + 1;
?>
<tr>
<td><?php echo $count; ?></td>
<td><?php echo $row['mdate']; ?></td>
<td><?php echo $row['man_detail']; ?></td>
<td><?php echo $row['last_mile']; ?></td>
<td><?php echo $row['next_mile']; ?></td>
<td><?php echo $row['warranty']; ?></td>
<td><?php echo $row['cost']; ?></td>
<td><?php echo $row['driver_name']; ?></td>
</tr>
<?php                    
         //}
      mysql_close($db);
?>

请帮帮我!!!

您需要围绕获取和打印记录的逻辑放置一个 while 循环:

while ($row = mysql_fetch_array($result)) {
     $count = $count + 1;
?>
  <tr>
  <td><?php echo $count; ?></td>
  <td><?php echo $row['mdate']; ?></td>
  <td><?php echo $row['man_detail']; ?></td>
  <td><?php echo $row['last_mile']; ?></td>
  <td><?php echo $row['next_mile']; ?></td>
  <td><?php echo $row['warranty']; ?></td>
  <td><?php echo $row['cost']; ?></td>
  <td><?php echo $row['driver_name']; ?></td>
  </tr>
<?php                    
} // end while
mysql_close($db);
?>
