小案例:微型博客,案例:微型博客

 

# 初级案例说明

源码下载

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;

}
