php留言本:PHP+TEXT留言本(一)

来源: 发布时间:星期一, 2009年1月12日 浏览:4次 评论:0
  大家知道,数据库对于网络来说重要性.由于cgi复杂,现在asp和php+mysql已经成为主流.几乎所有个人网页都要用到留言本,可是申请留言本很不稳定.这为网上交流带来了诸多不便.所以,希望拥有自己留言本朋友越来越多.

  但是,免费个人主页支持asp和php很少.笔者现在向您推荐动站指南,(http://www.knowsky.com)支持php.这样您便有了能够拥有自己留言本基础.现在,我就通过个文本留言本例子来讲述php简单使用.

  首先,我们先确定,留言几个过程:写留言,发送,查看.(搜索)等等.而且对于斑竹来说,管理留言本又是不可或缺.这样我们就不妨定位于6个php文件,1个文本文件.6个php文件分别为:guest.php manage.php reply.php sys.php del.php edit.php,1个文本文件为:guest.txt

  先来看看guest.php内容,你当然可以直接将下面内容放到您php网页里,请尊重作者劳动,谢谢.

//guest.php:<?
  
require("sys.php");
($B1)
{
   ($message"" or $name"")
 {
 $errorm="<font color=red>出错了!!!</font>姓名和留言内容必填";

$time = date(Y年m月d日H小时i分);
$ip=$REMOTE_ADDR;
$name=encode($name);
$homepage=encode($homepage);
$from=encode($from);
$email=encode($email);
$message=StripSlashes($message);
$message=htmlspecialchars($message);
$message=check_strlen_long($message);
$message=nl2br($message);
$guestcontent = "<tr><td><font color=#AB00E1>留言内容:</font><br><!--content>$message<!--endcontent> ";
$guestcontent=$guestcontent."<br><font color=#6633FF>留言人大名:</font><!--name>$name<!--endname> ";
($email !="")
{$guestcontent=$guestcontent."<br><font color=#9900CC>电子信箱</font><a href="mailto:$email"><!--email>$email<!--endemail></a>"."$space";}
