投票问题

Question

我正在做一个facemash模拟，我遇到了一个问题。当我投票给第二张图片时，无论如何，获胜者是第一张。哪里有问题？网站：http://facemash123.shimansky.ru

<form METHOD=POST ACTION="rate.php">
<table width="auto" align="center">
    <tr align="center" width="auto" valign="top">
        <td><img src="images/<?=$images[0]->filename?>" /></td>
        <td><img src="images/<?=$images[1]->filename?>" /></td>
    </tr>
    <tr>
        <td><input type="submit" name="winner" value="Vote"></td>
        <td><input type="submit" name="winner" value="Vote"><td>

        <input type="hidden" name="first" value="<?=$images[0]->image_id?>">
        <input type="hidden" name="second" value="<?=$images[1]->image_id?>">
    </tr>
    <tr>
        <td><center>Wins: <?=$images[0]->wins?>, Fails: <?=$images[0]->losses?></center></td>
        <td><center>Wins: <?=$images[1]->wins?>, Fails: <?=$images[1]->losses?></center></td>
    </tr>
</table>
</form>

您的两个提交按钮提交相同的值，并且无法区分这两个图像。

可能将代码更改为：

    <td><input type="submit" name="winner" value="Vote for Img #1"></td>
    <td><input type="submit" name="winner" value="Vote for Img #2"><td>

然后在投票处理代码中：

switch($_POST['winner']) {
    case "Vote for Img #1":
        $vote_id = $_POST['first'];
        break;
    case "Vote for Img #2":
        $vote_id = $_POST['second'];
        break;
    default:
        die("VOTER FRAUD! CALL THE FEC!");
}
