我有一个执行两个 php 文件的 html 文件（竖起大拇指/竖起大拇指的测试页）...一个用于竖起大拇指，一个用于竖起大拇指。

我现在需要做的是将此代码插入页面（辩论状态辩论列表），以便可以对每个辩论标题进行排名并相应地上下移动。

和我一起工作的朋友已经完成了大部分编码工作，包括 PHP 和表格。

我的问题是：有没有办法在页面上的每个辩论标题旁边竖起大拇指，竖起大拇指？到目前为止，我得到的最好的结果是在桌子上方竖起/向下竖起大拇指。

//test.html

<a href="upvote.php" onClick="alert('You have given this item a thumbs up! You can change          
your vote, or leave it how it is.')"; onMouseOver="return changImage()" onMouseOut=  
"return changImageBack()" ><img
name="jsbutton2" src="Graphics/thumbs-up-unclicked.jpeg" width="75" height="75" border="0"
alt="javascript button"></a>

<script type="text/javascript">

document.images["jsbutton2"].src= "Graphics/thumbs-up.jpeg";

function changImageBack()

 return true;

从数据库中检索数据时，当您循环浏览每条数据库记录时，写入表的一行，并在执行此操作时显示缩略图图像。例如：

echo "<table>";

while { // loops through DB record matches...

    echo "<tr><td>" . $topic_name;

    if ($thumbs == 'UP') {
        echo "<img src='thumbsup.jpg'>";
    }
    else {
        echo "<img src='thumbsdown.jpg'>";
    }

    // Also, if you want clickable thumb up/down buttons, put them here 
    // and pass hidden form variables with the topic's unique record ID
    // & specific voting action to a submission page. 
    //
    // Sorta like this:
    // <form>
    // <input type='hidden' name='topicid' value='" . $id . ">
    // <input type='hidden' name='action' value='THUMBSUP'>
    // <input type='submit' value='THUMBS UP'>
    // </form>
    // & then repeat for thumbs down, only changing the 'action' field

    echo "</td><tr>";

}

echo "</table>";

有点道理？？？
