yii学习笔记(转载)

1. % YiiRoot/framework/yiic webapp WebRoot/testdrive
2.默认Yii框架的URL规则是http://hostname/index.php?r=controllerName/actionName&id=1
3.$this->render('index',array('a'=>"123"));
4. 

  $hostname=Yii::app()->request->userHost;
   $status=$_REQUEST['status'];
5.
    'request'=>array(
           'class'=>'CHttpRequest',
       ),
   $host=Yii::app()->request->hostInfo;
   $this->render('index',array('a'=>"123",'b'=>$host));
6.
   $name=$_POST["name"];
   $pass=$_POST["pass"];
   $this->render('result',array('a'=>$name,'b'=>$pass));
7.改变显示模板 $this->layout = 'admin';

8.php yiic shell config/main.php

9.model Aadmins
  crud Department


10. $model=Aadmins::model()->find();
   print_r($model);

11.<formaction="/yemmys/yemmys/index.php?r=site/login"method="post">

12.<input name="LoginForm[username]"id="LoginForm_username" type="text" value=""/>

13.$this->redirect('index.php?r=admin/manage');

14.Yii::app()->user->name

15.public function actionLogout()
   {
      Yii::app()->user->logout();
      $this->redirect(Yii::app()->homeUrl);
   }

16.<?php echoYii::app()->request->baseUrl;?>/css/screen.css

17.dirname(Yii::app()->BasePath)

18.Yii::getPathOfAlias('webroot')

19.
           array('modified','default',
             'value'=>new CDbexpression_r('NOW()'),
             'setOnEmpty'=>false,'on'=>'update'),
           array('created,modified','default',
             'value'=>new CDbexpression_r('NOW()'),
             'setOnEmpty'=>false,'on'=>'insert')
             
20. ckeditor:


21.'viewButtonUrl'=>'Yii::app()->createUrl("/yemmysnews/view",array("id" => $data->newsid))',

22.在model里加：
    publicfunction beforeSave()
    {
       $pass = md5($this->password);
       $this->password = $pass;
       return true;
    }

23.Yii::app()返回的是我们在入口程序中建立的应用对象。
根据这个配置。我们可以在程序的任何地方通过使用 Yii::app()->db来获取连接到数据库的对象。


      
      Yii::log('eeeee1231123','info');
      $connection=Yii::app()->db;
      $connection->active=true;
      $command=$connection->createCommand("select`managername`,`password` from cdb_yemmysmanagers");
      $command->execute();  // a non-query SQL statement execution
      // or execute an SQL query and fetch the resultset
      $reader=$command->query();
      // each $row is an array representing a row ofdata
      foreach($reader as $row)
      {
         Yii::log($row['password'],'info');
      }
      
      $connection->active=false;



24.Yii::log('1231123','info');

25.
array_push --  将一个或多个单元压入数组的末尾（入栈） ,
将 array 当成一个栈，并将传入的变量压入 array 的末尾。array 的长度将根据入栈变量的数目增加。


array_combine -- 创建一个数组，用一个数组的值作为其键名，另一个数组的值作为其值

26.yii view 弹出新窗口

<script type="text/javascript">
$(function(){  
   $("a.view").attr("target","_blank");
});  

</script>

27.  Chtml

28.<?php echoCHtml::beginForm('','post',array('enctype'=>'multipart/form-data'));?>

29.验证码
（1）public function actions() {
    returnarray(
       'captcha'=> array(
           //加载外部的action class
      'class' => 'CCaptchaAction',
           //设置验证码图片背景色属性
