php yii框架学习笔记一：入门体验，初次要了解的那些事._PHP教程

 　创建几张表格~  简单说明一下，　　tbl_post blog 表 tbl_comment 评论表　，　tbl_user 用户表 tbl_tag 标签表　　直接运行下面的sql 即可.

CREATE DATABASE /*!32312 IF NOT EXISTS*/`yii` /*!40100 DEFAULT CHARACTER SET utf8 */;

USE `yii`;

DROP TABLE IF EXISTS `tbl_comment`;

CREATE TABLE `tbl_comment` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `content` text,
  `status` tinyint(1) DEFAULT '0',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `author` int(10) DEFAULT NULL,
  `email` char(255) DEFAULT NULL,
  `post_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS `tbl_lookup`;

CREATE TABLE `tbl_lookup` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` char(20) DEFAULT NULL,
  `code` char(20) DEFAULT NULL,
  `type` int(11) DEFAULT NULL,
  `position` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS `tbl_post`;

CREATE TABLE `tbl_post` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` char(20) DEFAULT NULL,
  `content` text,
  `tags` char(255) DEFAULT NULL,
  `status` tinyint(2) DEFAULT '0',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `update_time` datetime DEFAULT NULL,
  `author_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

/*Data for the table `tbl_post` */

insert  into `tbl_post`(`id`,`title`,`content`,`tags`,`status`,`create_time`,`update_time`,`author_id`) values (1,'111','222222','3333',1,'2012-08-08 00:00:00','2012-08-08 00:00:00',2);

/*Table structure for table `tbl_tag` */

DROP TABLE IF EXISTS `tbl_tag`;

CREATE TABLE `tbl_tag` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` char(20) DEFAULT NULL,
  `frequency` int(11) DEFAULT '1',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS `tbl_user`;

CREATE TABLE `tbl_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` char(20) DEFAULT NULL,
  `password` char(32) DEFAULT NULL,
  `email` char(100) DEFAULT NULL,
  `sex` int(11) DEFAULT '0',
  `profile` text,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

insert  into `tbl_user`(`id`,`username`,`password`,`email`,`sex`,`profile`) values (1,'admin','e10adc3949ba59abbe56e057f20f883e',NULL,0,NULL),(2,'demo','e10adc3949ba59abbe56e057f20f883e',NULL,0,NULL);

2 修改yii 的配置文件. protected/config/main.php  

//约第五十行。
//  'db'=>array(
//   'connectionString' => 'sqlite:'.dirname(__FILE__).'/../data/testdrive.db',
//  ),
  // uncomment the following to use a MySQL database

  'db'=>array(
   'connectionString' => 'mysql:host=192.168.1.33;dbname=yii',
   'emulatePrepare' => true,
   'username' => 'root',
   'password' => 'admin',
   'charset' => 'utf8',  'prefix' => 'tbl'
            'tablePrefix'=>'tbl_'
  ),
//约第21行，打开gii~
'modules'=>array(
  // uncomment the following to enable the Gii tool

  'gii'=>array(
   'class'=>'system.gii.GiiModule',
   'password'=>'123456',
   // If removed, Gii defaults to localhost only. Edit carefully to taste.
     'ipFilters'=>array('127.0.0.1','192.168.1.7'),
  ),

 ),

         $user = User::model()->findByAttributes(array('username' => $this->username));
        if ($user === null) {
                $this->errorCode = self::ERROR_USERNAME_INVALID;
        } else if ($user->password !== md5(trim($this->password))) {
                $this->errorCode = self::ERROR_PASSWORD_INVALID;
        } else {
                $this->setState('id', $user->id);
                $this->setState('username', $user->username);
                $this->errorCode = self::ERROR_NONE;
        }
        return !$this->errorCode;
