Question

我的数据库中显示2个结果。两个结果都代表了汽车。我需要在下面创建的表单中显示这些结果。目前它成功显示一个结果，但我需要显示这些表的几个结果。一旦我开始工作，我将添加更多的汽车。有任何想法吗？

Answer 1

                    $_SESSION['car'] = $row['car'];
                    $_SESSION['details'] = $row['details'];
                    $_SESSION['price'] = $row['price'];
                }

每一个新行都会覆盖旧行。

您可以在while循环中创建html，如下所示：

while($row=mysql_fetch_assoc($result))
{
?>
<form method="post" action="car.php">
     Car: <input type="text" name="country" value="<?php echo $row['car']; ?>" readonly><br>
     Details: <input type="text" name="country" value="<?php echo $row['details']; ?>" readonly><br>
     Price: <input type="text" name="country" value="<?php echo $row['price']; ?>" readonly><br>
     <img style="width: 130px; height: 100px" img alt="car"src="image/astra.jpg" /&gt;' />
      <input type="submit" value="Submit">
</form> // now you makes a form for each car
<?php
}

Answer 2

您需要在循环中输出表单，就像您刚刚结束会话变量一样，这样您就可以获得表格中的最后一辆车了。

<form method="post" action="car.php">

<?php while($row=mysql_fetch_assoc($result)) { ?>

  Car: <input type="text" name="country" value="<?php echo $row['car']; ?>" readonly><br>
  Details: <input type="text" name="country" value="<?php echo $row['details']; ?>" readonly><br>
  Price: <input type="text" name="country" value="<?php echo $row['price']; ?>" readonly><br>
  <img style="width: 130px; height: 100px" img alt="car"src="image/<?php echo $row['img']; ?>" /&gt;' />

<?php } ?>

<input type="submit" value="Submit">
</form>

我建议将图像名称存储在数据库中，如上所示。目前，该表格非常多余，但是当您提交表格时，您只需提交表格中的最后一辆车，您需要设法让用户选择他们想要的车。

编辑：选择特定车辆的代码

我只是快速地把它放在一起，对不起任何错误。

<form method="post" action="car.php">
  <table>
    <tr>
      <th>Image</th>
      <th>Name</th>
      <th>Details</th>
      <th>Price</th>
      <th></th>
    </tr>
  <?php while($row=mysql_fetch_assoc($result)) { ?>
    <tr>
      <td><img style="width: 130px; height: 100px" alt="<?php echo $row['car']; ?>" src="image/<?php echo $row['img']; ?>" /></td>
      <td><?php echo $row['car']; ?></td>
      <td><?php echo $row['details']; ?></td>
      <td><?php echo $row['price']; ?></td>
      <td><input type="radio" name="selected_car" value="<?php echo $row['car']; ?>" /></td>
    </tr>
  <?php } ?>
  </table>
  <input type="submit" value="Submit">
</form>

然后，当您提交至car.php时，$_POST['selected_car']的值将是用户选择的任何一辆汽车。

我强烈建议在该表中添加一个ID列，并使用它代替单选按钮中的汽车名称。

我还强烈建议您查看一些PHP / MySQL教程，以便掌握基础知识。 This非常适合开始使用PHP。
