新手做一个php留言板的问题，请求大牛

在网上根据视频用php编写了一段代码，只是链接数据库和编写页面的代码，我用的是nginx，但是遇到了如下问题：

用submit定义了提交按钮，但是点完后并没有弹出添加留言成功，而是打开了另一个网页显示405 not allowed！

在网上找了很多这方面得改进办法都没有用。

求大牛帮我看看我的代码和配置文件是否有问题，以下是我的代码和我的配置文件

代码：<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>添加留言</title>
<script type="text/javascript">
function checksmt()
{
var t=document.getElementById('title').value;
var c=document.getElementById('content').value;
if(t.length<1 || c.length<1)
{
  alert("留言标题内容是必填项")；
  return false;
}
return true;
}
</script>
</head>
<body style="margin:40px auto">
<div style="margin:90px atuo;margin-left:90px">
<form action="add.php" method="post" onsubmit="return checksmt()">
<b>标题:</b>  &n
<input id="content" style="margin-left:90px" type="submit" name="smt" value="添加留言"/>
     
<input type="reset" name="reset" value="重置"/>
</form>
</div>
<?php
if($_POST['smt'])
{
$title=mysql_escape_string(trim($_POST['title']));
$content=mysql_escape_string(trim($_POST['content']));

$con=mysql_connect('localhost','root','')or die ('error in connection to mysql server');
mysql_select_db('test',$con);
mysql_query("SET NAMES 'utf-8'",$con);
$sql="INSERT INTO liuyan(title,content）VALUES('".$title."','".$content."')";
if(mysql_query($sql,$con))
{
  echo '<script type="text/javascript">alert("添加留言成功")</script>';
}
else{
  echo '<script type="text/javascript">alert("添加留言失败")</script>';
}
}bsp; <input id="title" type="text" name="title" size="37"/>
