Yii如何使用model来上传多个文件

时间:2021-07-01 10:21:17 帮助过:4人阅读

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:

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?
