应用执行流程:
浏览器向服务器发送 Http Request | 控制器(protected/controllers) | |---> Action | 创建模型 (Model) | 检查$_POST输入 | 渲染视图 | render()第二个参数作为控制器与视图接口参数 | |----> View (protected/views) | 使用$this访问控制器的变量(包括layout, widget) -----------------------------------------------------------------
视图渲染流程:
render($view, $data, $return) | beforeRender() | 渲染View文件,调用renderPartial(),要求处理输出结果 | |----> 根据$view得到viewFile文件名 | renderFile(),要求返回渲染结果,做下一步处理 | |-----------> 获取widget的数目 | 从Yii::app()获得render CWebApplication::getViewRenderer 查询component[‘viewRenderer‘],默认没有配置 | Then, 调用renderInternal() | |---------> require View文件,渲染,根据需要返回渲染结果 | |<---------------| | |<-------------------| | 处理输出结果processOutput() | 按照caller参数,返回输出,而不是echo输出 |<--------------| | 渲染layout文件 | ----------------------------------------------------------------------
加载控制器及其方法:
根据route信息,获得当前控制器 | 初始化当前控制器,CController::init(),默认为空 | 执行当前控制器,CController::run() | |----> 创建action,为空则默认为index | 得到CInlineAction的实例 | 用父对象执行beforeControllerAction:默认是CWebApplication,直接返回TRUE | 执行action |----> 备份原来的action | 执行beforeAction() | runWithParams()----> 实际上是执行CInlineAction->runWithParams() | 在实例中,执行SiteController->actionIndex() | 渲染页面:render(‘index‘) | |<--------------------------| | 执行afterAction() | 恢复原来action | |<----------| | 用父对象执行afterControllerAction:默认是CWebApplication,为空 |<------------| 完成 ----------------------------------------------------------------
应用执行流程:
index.php | require_once($yii) | |------------->yii.php | require(YiiBase.php) | |---------------->YiiBase.php | Define YII_XXX global variable | Define Class YiiBase | Autload Class YiiBase (自动加载类机制) | require interface.php | |<------------------| | define null Class Yii | |<--------------| | createWebApplication($config)---------->| | YiiBase::createApplication(‘CWebApplication‘,$config) | Create Instance of CWebApplication | |--------->CWebApplication | CApplication($config)构造函数 | |------>| setBasePath | set path alias | preinit() 空方法 | initSystemHandlers() | configure($config) 将配置文件信息保存到Application | attachBehaviors() | preloadComponents() --> 装载在configure($config)中配置需要preload的components | init() | |<------| | |<------------| | |<----------------------------------| | app->run() | |---->CWebApplication::processRequest() | |----> CWebApplication::runController($route) | |---->createController($route) | 如果$route是空,添加默认controller,对于CWebApplication的controller是"site" | Controller类是SiteController,require该类文件 | 如果该类是CController的子类,修改id[0]为大写,创建该类的实例 | |---->CSiteController | extends from Controller 这是客户化控制器的基本类,存在于components下 定义了页面的通用布局 | 使用CController构造函数创建对象CSiteController,具体初始化数据见yii-1.png | |<--------| 备份$this->_controller $this->_controller = $controller | 调用控制器类的init()方法,默认为空 | 调用控制器类的run()方法,默认为CController的run() | |---->createAction() | if($actionID===‘‘) $actionID设置为$this->default ("index") | |Yes |----> return CInlineAction($this, $actionID) |No | 从Map创建 | | 执行当前类CInlineAction的父类CAction的构造函数 | 设置_controller和$id | | |<---------------| | | 这里得到一个CAction的实例 | $this->getModule()作为parent,为空则使用Yii::ap | $parent->beforeControllerAction() ?? | $this->runActionWithFilters($action,$this->filters()); | $parent->afterControllerAction($this,$action); |<--------| | 恢复原来的$oldController |<-----------| | |<--------------| | End of processRequest() | |<-----------------| | End of app->run() ------------------------------------------------------------
获取控制器和方法的ID
转载:http://code.dimilow.com/how-to-get-current-controller-name-and-action-name-in-yii/
By Dimi Low on July 7th, 2010 (6 responses)
To get current controller name/id inside your controller, or view
$controllerId = Yii::app()->controller->id;
//or
$controllerId = $this->getId();
To get current action name/id being executed, if you are inside beforeAction() or afterAction(), use the received CAction argument
//inside beforeAction or afterAction
public function beforeAction($action)
{
$actionId = $action->id;
...
or just elsewhere inside your controller
$actionId = $this->getAction()->getId();
----------------------------------------------------
使用YiiMailMessage发送邮件:
安装yii-mail到protected/extension下
配置protected/config/main.php,如下
‘import‘ => array(
......
‘application.extensions.yii-mail.*‘,
),
......
‘components‘ => array(
‘mail‘ => array(
‘class‘ => ‘application.extensions.yii-mail.YiiMail‘,
‘transportType‘ => ‘smtp‘, /// case sensitive!
‘transportOptions‘ => array(
‘host‘ => ‘mail.syncomni.com‘,
‘username‘ => ‘huajian@syncomni.com‘,
// or email@googleappsdomain.com
‘password‘ => ‘Sitbwp4m2w‘,
// ‘port‘ => ‘465‘,
// ‘encryption‘ => ‘ssl‘,
),
// ‘viewPath‘ => ‘application.views.mail‘,
‘logging‘ => true,
‘dryRun‘ => false
),
),
发送邮件
// 发送电子邮件
$message = new YiiMailMessage;
$message->setSubject($model->notice_subject);
$message->setBody($model->notice);
$message->setTo(‘kevin@syncomni.com‘);
$message->from = Yii::app()->params[‘adminEmail‘];
Yii::app()->mail->send($message);
