php中加入javascript想要没输入title的时候跳出对话框以后在回到ckeditor里面重新编辑

php中加入javascript想要没有输入title的时候跳出对话框以后在回到ckeditor里面重新编辑。

我这样可以弹出这个消息提示框
我用了一个if语句。然后想要实现一个功能：按了确定以后在回到首页。可是当我添加了注释掉的这句话以后就是直接跳转到之前的页面了，不会弹出对话框了。怎么办

求解！！！
这是a.php:

<?php<br />
include('conn.php');<br />
$head=$_POST['head'];<br />
$content=$_POST['content'];<br />
<br />
<br />
?><br />
<html><br />
<head><br />
	<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/><br />
<title><br />
a<br />
</title><br />
	<meta name="keywords" content="关键字列表" /><br />
	<meta name="description" content="网页描述" /><br />
	<link rel="stylesheet" type="text/css" href="" /><br />
	<style type="text/css"><br />
	*{<br />
			font-size:20px;	/*设置当前网页的“基本字体大小为12px*/<br />
		}<br />
	.content{<br />
		color=#0066ff text-align=right border-bottom=dashed 1px grey<br />
	}<br />
</style><br />
</head><br />
<body><br />
	<br />
<br />
	<?php<br />
	if($head!=NULL)<br />
   	{<br />
   		$sql="insert into ckfinder values('$head','$content')";<br />
		mysql_query($sql) or die(mysql_error());<br />
		$sql="select *from ckfinder";<br />
   		echo "<u>title:</u>&nbsp&nbsp&nbsp&nbsp</u>$head<br/>";<br />
   	    echo "<u>date:</u>&nbsp&nbsp&nbsp&nbsp".date("Y").".".date('m').".".date('d');<br />
   	    echo"<br/>";<br />
        echo "<u>content</u>:</br>&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp<br />
        	<table border='0' width='400' align='left' cellspacing='0' ><tr><td class='.content' >$content</td></tr><table>";<br />
        echo"</hr>" ;<br />
    } <br />
    else <br />
    {<br />
		echo"<script type='text/javascript'>alert('请输入标题!')</script>";<br />
	    header("Location:ck.php");<br />
	}<br />
    ?><br />
    <br />
</body><br />
</html><br />




这是ck.php

<br>
[code=php]<br>
<br>
<br>
	<meta><br>
	<title>
<br>
        ckeditor与ckfinder的配置和调用<br>
	</title><br>
<script></script> <div class="clear">
                 
              
              
        
            </div>
