发布信息需要加个字段，password用来填写密码的，删除信息根据填写的密码删除。
<?php
if($navinfor['password'])
{
echo "<a href='/e/delnews/fwxx.php?classid=[!--self.classid--]&id=[!--id--]' target='_blank'>删除信息</a>（需密码）";
}
?>fwxx.php这个文件的内容如下
<?php
require("../class/connect.php");
include("../class/db_sql.php");
include("../class/config.php");
$link=db_connect();
$empire=new mysqlquery();
$id=(int)$_GET['id'];
$classid=(int)$_GET['classid'];
//检查参数
if(!$classid || !$id)
{
echo"<script>alert('Error!');history.go(-1);</script>";
exit();
}
if ($_POST['enews']=='DelNews')
{
$key=$_POST['key'];
$password=$_POST['password'];
//验证码
$checkplkey = getcvar ('checkplkey');
if (($key != $checkplkey OR empty ($checkplkey)))
{
printerror ('FailKey', 'history.go(-1)', 1);
}
$query="select password,id,title from {$dbtbpre}ecms_fwxx where id='$id' and classid='$classid'";
$r=$empire->fetch1($query);
if(!$r[id] or !$r[password])
{
echo"<script>alert('此信息密码为空或不存在,不能删除！');history.go(-1);</script>";
exit();
}
//验证信息密码
if ($password==$r[password])
{
$r=$empire->query("update {$dbtbpre}ecms_fwxx set checked='0' where classid='$classid' and id='$id'");
echo"<script>alert('您的删除请求已提交，该信息将在12小时内删除！');window.location='/';</script>";
}
else
{
echo"<script>alert('信息密码错误，请核对密码后再试！');window.location='fwxx.php?classid=$classid&id=$id';</script>";
}
}
else
{
?>
<script language="javascript" type="text/javascript">
function checkForm()
{
var frm;
frm = document.getElementById("form1");
if(frm.password.value == ""){
alert("密码不能为空!");
frm.password.focus();
return false;
}
if(frm.key.value.length < 4){
alert("请填写验证码");
frm.key.focus();
