求用PHP写一个简单基本的留言板代码，有点急
数据库的创建
CREATE DATABASE GBOOK;
CREATE TABLE `gbook` (
`id` INT( 255 ) UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`name` VARCHAR( 10 ) NOT NULL ,
`sex` TINYINT( 1 ) UNSIGNED NOT NULL ,
`email` VARCHAR( 255 ) NOT NULL ,
`info` TEXT NOT NULL ,
`ip` VARCHAR( 15 ) NOT NULL ,
`time_at` DATETIME NOT NULL
)
主要页面有:
input.html为初始页
insert.php为把输入内容送入数据库
show.php显示留言板内容
change.php修改留言板内容的界面
del.php删除留言板内容
change_ok.php修改留言板内容并送入数据库
input.html

关于PHP删除和修改留言板留言功能的代码，急
登录时
用$_SESSION保存下
例如$_SESSION['user']="$user";
管理员登录时再写个$_SESSION['username'];
在留言后边加上
?php
if(isset($_SESSION['username'])
||
$_SESSION['user']==$username){
'a
href="update.php?id='.$row['id'].'"修改/a';?
这样只有登录的管理员才能看到这个修改
并且能修改
然后在update.php写更新操作
删除一样的
php制作留言板代码
form action="留言方法，也可以是留言.php文件，也可以是当前页面" method="get"
pFirst name: input type="text" name="fname" //p
pLast name: input type="text" name="lname" //p
input type="submit" value="Submit" /
/form
php:
$fname=$_GET[fname];
$lname=$_GET[lname];
$sql = "insert into 表名(字段1,字段2) values('$fname','$lname')";
if(!$sql ){
return "插入失败";
}else{
return "成功添加数据";
}
