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.<form action="/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 echo Yii::app()->request->baseUrl; ?>/css/screen.css
17.dirname(Yii::app()->BasePath)
18.Yii::getPathOfAlias('webroot')
19.
array('modified','default',
'value'=>new CDbExpression('NOW()'),
'setOnEmpty'=>false,'on'=>'update'),
array('created,modified','default',
'value'=>new CDbExpression('NOW()'),
'setOnEmpty'=>false,'on'=>'insert')
20. ckeditor:
21. 'viewButtonUrl'=>'Yii::app()->createUrl("/yemmysnews/view", array("id" => $data->newsid))',
22.在model里加：
public function 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 result set
$reader=$command->query();
// each $row is an array representing a row of data
foreach($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 echo CHtml::beginForm('','post',array('enctype'=>'multipart/form-data')); ?>
29.验证码
（1）public function actions() {
return array(
'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,
),
);
}
（2）
<?php widget("CCaptcha"); ?>
（3）
class User extends CActiveRecord {
public $verifyCode; //为User Model 设置一个新的属性
..........
