我以前是使用cformmodel来上传图片（单张）。比如registerform来注册用户上传照片并使用缩略图：
'email的格式不合法'), array('password', 'required'), array('gender','in','range'=>array(0,1)), array('homeland','required','message'=>'家乡必填，而且不容易更改'), array ('homeland','validateHome'), array('imei','required','message'=>'imei必填'), array('birthday','required','message'=>'birthday必填'), array('avatar','file','message'=>'必须设置一个头像') ); } /** * Declares attribute labels. */ public function attributeLabels() { return array( 'email'=>'用户名/邮箱/手机号/漫游号', 'password'=>'密码', 'gender'=>'性别', '' ); } /** * 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','Incorrect username or password.'); } } /** * 验证家乡是否合法。扩展到地级市 * * */ public function validateHome(){ $this->homeland; $this->addError('homeland','家乡不合法啊'); } /** * Logs in the user using the given username and password in the model. * @return boolean whether login is successful */ public function login() { if($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; } }
然后在Controller里面：

技术上面应用了三层结构，AJAX框架，URL重写等基础的开发。并用了动软的代码生成器及数据访问类，加进了一些自己用到的小功能，算是整理了一些自己的操作类。系统设计上面说不出用什么模式，大体设计是后台分两级分类，设置好一级之后，再设置二级并选择栏目类型，如内容，列表，上传文件，新窗口等。这样就可以生成无限多个二级分类，也就是网站栏目。对于扩展性来说，如果有新的需求可以直接加一个栏目类型并新加功能操作
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);
$imageName='img_big'.$preRand.$registerForm->avatar->extensionName;
$registerForm->avatar->saveAs('uploads/' . $imageName);
$registerForm->avatar = $imageName;
}
$path = dirname(Yii::app()->BasePath) . '/uploads/';
$thumb = Yii::app()->thumb; //与 $thumb=new Cthumb()有什么区别？
$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;
$registerForm->registerDate = time();
//save方法会自动验证
if ($registerForm->save() && $registerForm->login()) {
Yii::app()->db->getLastInsertID(); //取得插入的Id。但是
}
}
上传的时候主要是这里：
$registerForm->avatar = CUploadedFile::getInstance($registerForm, 'avatar');
但是现在遇到了一个问题。就是$registerForm继承了CFormModel，这个save方法是CActiveRecord的，为什么save方法就调用了呢？
此外，如果我要多文件上传，是不是
$file1=CUploadedFile::getInstance($registerForm, 'file1'); $file2=CUploadedFile::getInstance($registerForm, 'file2');
就可以了？

你好啊。这个多文件上传的这问题你解决了吗？
