这样做应该解决的问题，请尝试：

<div id="etc" class="page"> 
    <form action="<?php $_SERVER['PHP_SELF']?>" method="POST"> 
     <textarea name="textPost" id="textPost"></textarea> 
     <input type="submit" name="btnPost" id="btnPost" value="Post" /> 
     <div id="tae"> 
      <input type="text" name="display" id="display" value="0" /> 
     </div> 

     <!-- END FORM REMOVED HERE --> 

     <!-- FORM REMOVED HERE --> 

    <div id="delButtonDiv"> <input type="submit" value="Delete" name="btnDelete" /> </div> 
    </form> 
</div>

将帖子

有两个表单中的提交按钮后，那么你需要知道你正在采取什么行动，POST或删除，对吗？那么您可以在自己的PHP脚本创建一个基本的控制器到您的文章，这样的事情：

这里是形式 - ><form action="<?php $_SERVER['PHP_SELF']?>" method="POST">

和这里的提交按钮

<input type="submit" name="btnPost" id="btnPost" value="Post" /> 
<input type="submit" value="Delete" name="btnDelete" />

$_SERVER['PHP_SELF']告诉您它将表单数据发送给自己，如果是这样，那么做这样的事情在开始您的脚本：

if ($_POST[btnPost] == "Post") 
// do some action to post the data 

if ($_POST[btnDelete] == "Delete") 
// do some action to delete the data

明确了吗？

您已经使用两种形式，即提交按钮是属于第二种形式。
当您按下提交按钮，它只能提交一个空的形式。
移动提交按钮进入第一种形式要解决这个问题。

你的

<form action="<?php $_SERVER['PHP_SELF']?>" method="POST"> 
.. 
... 
<form action="<?php $_SERVER['PHP_SELF']?>" method="POST">

两行删除第二个，和

<form action="<?php $_SERVER['PHP_SELF']?>" method="POST"> 
       ^missing an echo

如果要提交回相同的URL，则不需要设置表单操作。

你是什么意思两种形式？我应该在哪里放置我的删除代码块？ – 2011-12-15 15:11:45

什么都没有发生先生。仍然没有任何反应:( – 2011-12-15 15:21:24

删除按钮必须与复选框位于您要提交到的相同表单中。

<form method="POST" action="videoJudge.php" > 
           ^______ url of the form you want to submit to. Possibly <?php echo $_SERVER['PHP_SELF']?> 

<input type="checkbox" name="checkbox[]" id="checkbox[]" value="'.$idNo.'" /> 
<input type="submit" value="Delete" name="btnDelete" /> 
</form>
