YII学习笔记

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

'backColor' => 0xffffff,

),

);
