工具：
Dreamweaver
php、mysql服务器
步骤/方法
首先是确定自己的留言板需求.例如:名字,邮件及留言内容.
一. 建立一个数据库guestbook。
CREATE TABLE IF NOT EXISTS `content` (
`id` int(11) NOT NULL auto_increment,
`name` varchar(20) NOT NULL,
`email` varchar(50) NOT NULL,
`content` varchar(200) NOT NULL,
PRIMARY KEY (`id`))
ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=3;
二. 新建config.php
< ? php
$q = mysql_connect("服务器","数据库用户","数据库密码");
if(!$q)
{
die("Could not connect: " . mysql_error());
}
mysql_query("set names utf8"); //以utf8读取数据
mysql_select_db("guestbook",$q); //数据库
?>
三. 新建index.php
< ?php
include("config.php"); //引入数据库连接文件
$sql = "select * from content"; //搜索数据表content
$resule = mysql_query($sql,$q);
?>
< html>
< meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
< body>
< table width="678" align="center">
< tr>
< td colspan="2">< h1>留言本< /h1>< /td>
< /tr>
< tr>
< td width="586">< a href="index.php">首页< /a> | < a href="liuyan.php">留言< /a>< /td>
< /tr>
< /table>
< p>
< ?
while($row=mysql_fetch_array($resule))
{
?>
< /p>
< table width="678" border="1" align="center" cellpadding="1" cellspacing="1">
< tr>
< td width="178">Name:< ? echo $row[1] ?>< /td>
< td width="223">Email:< ? echo $row[2] ?>< /td>
< /tr>
< tr>
< td colspan="4">< ? echo $row[3] ?>< /td>
< /tr>
< tr>
< /table>
< ?
}
?>
< /body>
< /html>
四. 新建liuyan.php
< html>
< body>
< meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
< table width="678" align="center">
< tr>
< td colspan="2">< h1>留言本< /h1>< /td>
< /tr>
< tr>
< td width="586">< a href="index.php">首页< /a> | < a href="liuyan.php">留言< /a>< /td>
< /tr>
< /table>
< table align="center" width="678">
< tr>
< td>
< form name="form1" method="post" action="post.php">
< p>
Name：
< input name="name" type="text" id="name">
< /p>
< p>Email：< input type="test" name="email" id="email">< /p>
< p>
留言：
< /p>
< p>
< textarea name="content" id="content" cols="45" rows="5">< /textarea>
< /p>
< p>
< input type="submit" name="button" id="button" value="提交">
< input type="reset" name="button2" id="button2" value="重置">
< /p>
< /form>
< /td>
< /tr>
< /table>
< /body>
< /html>
五. 新建post.php
< ?php
header("content-Type: text/html; charset=utf-8");
include("config.php");
$name= $_POST["name"];
$email= $_POST["email"];
$patch = $_POST["content"];
$content = str_replace("
","< br />",$patch);
$sql = "insert into content (name,email,content) values ("$name","$email","$content")";
mysql_query($sql);
echo "< script>alert("提交成功！返回首页。");location.href="index.php";< /script>";
?>
这样已经成功的写出一个留言板了。
第二部分
此次将在上面版本上加多管理，回复等功能。
首先在sql中字节。
ALTER TABLE `content` ADD `reply` VARCHAR( 200 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL AFTER `content`
一. 新建login.php
< html xmlns="http://www.w3.org/1999/xhtml">
< meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
< title>无标题文档< /title>
< /head>
< body>< table width="678" align="center">
< tr>
< td colspan="2">< h1>留言本< /h1>< /td>
< /tr>
< tr>
< td width="586">< a href="index.php">首页< /a> | < a href="liuyan.php">留言< /a>< /td>
< /tr>
< /table>
< table align="center" width="678">
< tr>
< td align="center">
< form name="form1" method="post" action="login2.php">
< label for="textfield">< /label>
< p> < /p>
< p>帐号：
< input type="text" name="name" id="name">
< /p>
< p>密码：
< input type="password" name="pw" id="pw">
< /p>
< p>
< input type="submit" name="button" id="button" value="提交">
< input type="reset" name="button2" id="button2" value="重置">
< /p>
< /form>< /td>
< /tr>
< /table>
< /body>
< /html>
二.login2.php
< ?
session_start();
header("content-Type: text/html; charset=utf-8");
$name = $_POST["name"];
$pw = $_POST["pw"];
if($name == "admin" && $pw == "admin"){
$_SESSION["adminname"] = $name;
echo "< script>alert("登录完成，返回首页!");location.href="index.php";< /script>";
}else{
echo "< script>alert("错误!");location.href="login.php";< /script>";
}
?>
三. 在原有的index.php上添加
< ?php
session_start();
include("config.php");
$sql = "select * from content";
$resule = mysql_query($sql,$q);
?>
< html>
< meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
< body>
< table width="678" align="center">
< tr>
< td colspan="2">< h1>留言本< /h1>< /td>
< /tr>
< tr>
< td width="586">< a href="index.php">首页< /a> | < a href="liuyan.php">留言< /a>< /td>
< td width="80">
// 新增管理员登录
< ?php
if (isset($_SESSION["adminname"]) && $_SESSION["adminname"] == "admin"){
echo "< a href="logout.php">登出< /a>";
}else{
echo "< a href="login.php">管理员登录< /a>";
}
?>
< /td>
< /tr>
< /table>
< p>
< ?
while($row=mysql_fetch_array($resule))
{
?>
< /p>
< table width="678" border="1" align="center" cellpadding="1" cellspacing="1">
< tr>
< td width="178">Name:< ? echo $row[1] ?>< /td>
< td width="223">Email:< ? echo $row[2] ?>< /td>
< td width="100">
< ?php
if(isset($_SESSION["adminname"]) && $_SESSION["adminname"] == "admin"){
echo "< a href="huifu.php?id=" . $row[0] . "">回复< /a>";
echo " | " . "< a href="delete.php?id=" . $row[0] . "">删除< /a>";
} else {
echo "";
}
?>
< /td>
< /tr>
< tr>
< td colspan="4">< ? echo $row[3] ?>< /td>
< /tr>
< tr>
< td colspan="4">< ?
if($row[4] == ""){
?>
< ? echo "暂无回复。";?>
< ? }else {echo "管理员回复：". $row[4]; } ?>< /td>
< /tr>
< /table>
< ?
}
?>
< /body>
< /html>
四. 新建huifu.php
< ?php
include("config.php");
$sql = "select * from content where id=".$_GET["id"];
$resule = mysql_query($sql,$q);
SetCookie("id",$_GET["id"]);
session_start();
header("content-Type: text/html; charset=utf-8");
if(empty($_SESSION["adminname"])){
exit("< script language="javascript">alert("您尚未登录后台，或登录已超时，请重新登录！");window.location.href="login.php";< /script>");
}
?>
< !DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
< html xmlns="http://www.w3.org/1999/xhtml">
< head>
< meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
< title>无标题文档< /title>
< /head>
< body>
< table width="678" align="center">
< tr>
< td colspan="2">< h1>留言本< /h1>< /td>
< /tr>
< tr>
< td width="586">< a href="index.php">首页< /a> | < a href="liuyan.php">留言< /a>< /td>
< /tr>
< /table>
< table align="center" width="678">
< tr>
< td>
< form name="reply" method="post" action="reply.php" >
< p>回复：
< ?
while($row=mysql_fetch_array($resule))
{
echo $row[3];
}
?>
< /p>
< p>
< textarea name="reply" id="reply" cols="45" rows="5">< /textarea>
< /p>
< p>
< input type="submit" name="button" id="button" value="回复" />
< input type="reset" name="button2" id="button2" value="重置" />
< /p>
< /form>
< /td>
< /tr>
< /table>
< /body>
< /html>
五. reply.php 回复留言提交页面.
< ?
include("config.php");
$id = $_COOKIE["id"];
$sql = "select * from content";
header("content-Type: text/html; charset=utf-8");
$patch = $_POST["reply"];
$reply = str_replace("
","< br />",$patch);
$resule = mysql_query("UPDATE `2`.`content` SET `reply` = "$reply" WHERE `content`.`id` ="."$id");
echo "< script>alert("回复成功!");location.href="index.php";< /script>";
?>
这样就可以建立出一个简单的管理.管理帐号都是admin 因为只是判别输入的是不是admin 是的话就把值输入进session中.
