一、结构如下
conn.php 为连接数据库文件
index.php 为首页,也是博客列表页 select * from weibo where $id order by id desc limit 10;
edit.php 为编辑页 UPDATE weibo SET `title`='$title',`contents`='$contents' where `id`='$hid'
del.php 为删除操作页
add.php 为添加页
view.php 为详情页
二、数据库
字段说明 id ,hit点击量,title标题,dates日期,contents内容
CREATE TABLE `weibo` (
`id` int(5) NOT NULL AUTO_INCREMENT,
`hit` int(11) NOT NULL,
`title` varchar(50) NOT NULL,
`dates` date NOT NULL,
`contents` text NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
三、注意点:
1.编辑时候,在表单中使用了隐藏域进行传递id
2.在搜索的时候巧妙使用了where $w ,
if(!empty($_GET['keys'])){
// $w = `title` like $_GET['keys'];
$w = " `title` like '%" . $_GET ['keys'] . "%' "; //使用模糊搜索
}else{
$w = 1; //此句代码转换到sql语句中没有实际意义。
//sql语句为select * from `weibo` where 1 order by id desc limit 10;
}
