SAE实践——创建简单留言板
1. 创建数据库
将mysaeapptest的数据库初始化之后，建立新的数据库，在PHPMyAdmin输入下列SQL。
CREATE TABLE IF NOT EXISTS `ny_diary` ( `id` int(10) NOT NULL AUTO_INCREMENT, `title` varchar(1000) NOT NULL, `content` varchar(5000) NOT NULL, `date` datetime NOT NULL, `user` varchar(100) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=40 ;
2. 在index.php中输入下列代码。
1 <?php 2 // 连主库 3 $link=mysql_connect(SAE_MYSQL_HOST_M.':'.SAE_MYSQL_PORT,SAE_MYSQL_USER,SAE_MYSQL_PASS); 4 5 // 连从库 6 // $link=mysql_connect(SAE_MYSQL_HOST_S.':'.SAE_MYSQL_PORT,SAE_MYSQL_USER,SAE_MYSQL_PASS); 7 8 //echo $key = md5("900821Ny"); 9 ?> 10 <!DOCTYPE html> 11 <html> 12 <head> 13 <title>Simple Message</title> 14 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 15 <meta http-equiv="X-UA-Compatible" content="IE=edge"> 16 <meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=1.0,user-scalable=0" /> 17 <meta name="apple-mobile-web-app-capable" content="yes"> 18 <meta name="apple-mobile-web-app-status-bar-style" content="black"> 19 <meta name="format-detection" content="telephone=no"> 20 21 <style> 22 a, a:visited, a:hover, a:link, a:active { text-decoration: none;
