php - 显示一个用户的所有订单

Question

<?php
include_once 'db.php';
$email = $_GET['email'];
$order_id = $_GET['order_id'];
$res=mysql_query("SELECT * FROM clients_buy WHERE email='$email'");
$row=mysql_fetch_array($res);
echo "<table border='1'>
<tr>
<th><center>order_id</center></th>
<th><center>item1</th>
<th><center>item2</th>
<th><center>item3</th>
<th><center>item4</th>
<th><center>item5</th>
</tr>";
while($row = mysql_fetch_assoc($res))
$row[] = $row;
echo "<tr>";
echo "<td><center>" . $row['user_id'] . "</center></td>";
echo "<td><center>" . $row['item1'] . "</center></td>";
echo "<td><center>" . $row['item2'] . "</center></td>";
echo "<td><center>" . $row['item3'] . "</center></td>";
echo "<td><center>" . $row['item4'] . "</center></td>";
echo "<td><center>" . $row['item5'] . "</center></td>";
echo '</tr>';
echo '</table>';
?>

我想在 php 页面中显示来自一个用户的所有订单。

正如 Sand 所说，请使用 mysqli 或 PDO。为什么你的 while 循环没有花括号？尽管尚未测试您的代码，但这似乎是一个错误的过程。 我会把它写成

while($row = mysql_fetch_assoc($res)){   
    echo "<tr>";
    echo "<td><center>" . $row['user_id'] . "</center></td>";
    echo "<td><center>" . $row['item1'] . "</center></td>";
    echo "<td><center>" . $row['item2'] . "</center></td>";
    echo "<td><center>" . $row['item3'] . "</center></td>";
    echo "<td><center>" . $row['item4'] . "</center></td>";
    echo "<td><center>" . $row['item5'] . "</center></td>";
    echo '</tr>';
}
echo '</table>';
