How does Yii use model to upload multiple files?

I used to use CFormModel to upload images (single sheet ). For example, RegisterForm is used to register a user to upload a photo and use a thumbnail: {code ...} then in Controller: {code ...} during the upload process, the following code is mainly used: {code ...} but now we have a problem.

  'Invalid email format '), array ('Password', 'required'), array ('gender', 'in ', 'range' => array (), array ('homeland', 'required', 'message' => 'hometown required, and not easy to change '), array ('homeland', 'validatehome'), array ('imei', 'required', 'message' => 'imei required '), array ('birthday ', 'requestred', 'message' => 'birthday required '), array ('Avatar', 'file ', 'message' => 'An Avatar must be set');}/*** Declares attribute labels. */public function attributeLabels (){ Return array ('email '=> 'user name/email/mobile phone number/Roaming number', 'Password' => 'Password', 'gender' => 'gender ', '');}/*** Authenticates the password. * This is the 'authenticate' validator as declared in rules (). */public function authenticate ($ attribute, $ params) {if (! $ This-> hasErrors () {$ this-> _ identity = new UserIdentity ($ this-> username, $ this-> password); if (! $ This-> _ identity-> authenticate () $ this-> addError ('Password', 'recorrect username or password. ') ;}}/*** verify that your hometown is legal. Extended to prefecture-level cities ***/public function validateHome () {$ this-> homeland; $ this-> addError ('homeland', 'hometown is illegal ');} /*** Logs in the user using the given username and password in the model. * @ return boolean whether login is successful */public function login () {if ($ this-> _ identity = null) {$ this-> _ identity = new UserIdentity ($ this-> username, $ this-> password); $ this-> _ identity-> setPersistentStates (array ()); $ this-> _ identity-> authenticate ();} if ($ this-> _ identity-> errorCode = UserIdentity: ERROR_NONE) {$ duration = 3600*24*10; // 10 days Yii: app ()-> user-> login ($ this-> _ identity, $ duration ); return true;} else return false ;}}

Then in the Controller:

Public function actionRegister () {$ registerForm = new RegisterForm (); if (isset ($ _ POST ['registerform']) {$ registerForm-> attributes =$ _ POST ['registerform']; $ RegisterForm-> avatar = CUploadedFile: getInstance ($ registerForm, 'Avatar '); if ($ registerForm-> avatar) {$ preRand = time (). mt_rand (0, 99999); $ imageName = 'img _ day '. $ preRand. $ registerForm-> avatar-> extensionName; $ registerForm-> avatar-> saveA S ('uploads /'. $ imageName); $ registerForm-> avatar = $ imageName;} $ path = dirname (Yii: app ()-> BasePath ). '/uploads/'; $ thumb = Yii: app ()-> thumb; // What is the difference between it and $ thumb = new Cthumb? $ Thumb-> image = $ path. 'img _ small '. $ preRand. $ registerForm-> avatar-> extensionName; $ thumb-> width = 130; $ thumb-> height = 95; $ thumb-> mode = 4; $ thumb-> directory = $ path; $ thumb-> defaultName = $ preRand; $ thumb-> createThumb (); $ thumb-> save (); $ registerForm-> thumb = $ thumb-> image; $ registerForm-> registerDate = time (); // The save method automatically verifies if ($ registerForm-> save () & $ registerForm-> login () {Yii: app ()-> Db-> getLastInsertID (); // obtain the inserted Id. But }}

This is the main part of the upload process:

$registerForm->avatar = CUploadedFile::getInstance($registerForm, 'avatar');

But now we have a problem. $ RegisterForm inherits CFormModel. The save method is CActiveRecord. Why is the save method called?

In addition, if I want to upload multiple files, is it true?

$file1=CUploadedFile::getInstance($registerForm, 'file1');$file2=CUploadedFile::getInstance($registerForm, 'file2');

That's it?
