大概过程是这样:
1、先要建一个数据表。
2、sql语句把留言板表单里的各项值写入数据表。
3、将数据调入后台显示,执行 *** 作。
把分页的显示部分,也就是上一页,下一页等等定义为一个函数,比如showpage然后直接
$smarty ->assign("showpage", $showpage)//直接显示分页显示部分
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,$q)
?>
<html>
<meta http-equiv="Content-Type" content="text/htmlcharset=utf-8" />
<body>
<table width="678" align="center">
<tr>
<td colspan="2"><h1>留言本</h1></td>
</tr>
<tr>
<td width="586"><a href="index.php">首页</a>| <a href="liuyan.php">留言</a></td>
</tr>
</table>
<p>
<?
while($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/htmlcharset=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/htmlcharset=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/htmlcharset=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/htmlcharset=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,$q)
?>
< html>
<meta http-equiv="Content-Type" content="text/htmlcharset=utf-8" />
<body>
<table width="678" align="center">
<tr>
<td colspan="2"><h1>留言本</h1></td>
</tr>
<tr>
<td width="586"><a href="index.php">首页</a>| <a href="liuyan.php">留言</a></td>
<td width="80">
// 新增管理员登录
< ?php
if (isset($_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/htmlcharset=utf-8")
if(empty($_SESSION["adminname"])){
exit("<script language='javascript'>alert('您尚未登录后台,或登录已超时,请重新登录!')window.location.href='login.php'</script>")
}
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/htmlcharset=utf-8" />
<title>无标题文档</title>
</head>
<body>
<table width="678" align="center">
<tr>
<td colspan="2"><h1>留言本</h1></td>
</tr>
<tr>
<td width="586"><a href="index.php">首页</a>| <a href="liuyan.php">留言</a></td>
</tr>
</table>
<table align="center" width="678">
<tr>
<td>
<form name="reply" method="post" action="reply.php" >
<p>回复:
<?
while($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/htmlcharset=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.
