Yii框架实现图片上传的方法详解

// autoloading model and component classes
  'import'=>array(
    'application.models.*',
    'application.components.*',
    'application.extensions.*',  #加上此行，意思为自动载入
  ),

public function actionIndex() {
    $model=new Upload;
    if(isset($_POST['Upload'])) {
      $model->image=CUploadedFile::getInstance($model,'image');
      $ext = $model->image->getExtensionName();
      $fileName = uniqid() . '.' . $ext;
      $model->image->saveAs('assets/' . $fileName);
      // 生成缩略图
      Image::thumb('assets/' . $fileName, 'assets/' . uniqid() . '.' . $ext);
    }
    $this->renderPartial('index', array('model'=>$model));
}
