    /**

     */
    public function actionGetThumb($path, $w, $h) {
        $file_name = md5($path . $w . $h);
        if (file_exists('./temp/' . $file_name . '.jpg')) {
            header('location:/temp/' . $file_name . '.jpg');
            Yii::app()->end();
        }
        Yii::import("ext.EPhpThumb.EPhpThumb");
        $thumb = new EPhpThumb();
        $thumb->init();
        $thumb->create('.' . $path)
                ->adaptiveResize($w, $h)
                ->save('./temp/' . $file_name . '.jpg')
                ->show();
    }

    /*
     * 图片显示
     */

    public function actionList() {
        $attache = Attache::model();
        $list = $attache->findAll();
        $this->render('list', array('list' => $list));
        die;
    }

    /**
     * 文件上传
     */
    public function actionIndex() {
        $path = getcwd() . 'uploads';
        $dir = DIRECTORY_SEPARATOR . date('Y') . DIRECTORY_SEPARATOR . date('m');
        $dir = str_replace("\", "/", $dir);
        $uploads_dir = str_replace("\", "/", $path . $dir);
        if (!is_dir($uploads_dir) || !is_writeable($uploads_dir)) {
            mkdir($uploads_dir, 0777, TRUE);
            touch($uploads_dir . '/index.html');
        }
        $uploaded = false;
        $model = new Upload();
        if (isset($_POST['Upload'])) {
            $model->attributes = $_POST['Upload'];
            $file = CUploadedFile::getInstance($model, 'file');
            $newName = substr(md5($file->extensionName . round((microtime(true) * 1000))), 0, 17) . '.' . $file->extensionName; // www.111cn.net
            $file_name = $uploads_dir . '/' . $newName;
            if ($model->validate()) {
                $attache = new Attache();
                $uploaded = $file->saveAs($file_name, TRUE);
                $attache->name = $file->getName();
                $attache->path = $dir . '/' . $newName;
                $attache->create_time = time();
                $attache->save();
            }
        }

        $this->render('index', array(
            'model' => $model,
            'uploaded' => $uploaded,
            'dir' => $uploads_dir,
        ));
    }
}

Upload.php:

<?php class Upload extends CFormModel { public $file; public function rules() { return array( array('file', 'file', 'types' => 'jpg, gif, png,zip'), ); } }

<?php /** * list.php * Created on: 2014-1-26 13:12:01 by Outsider */ ?> <?php foreach ($list as $v): ?> <img src="<?php echo Yii::app()->createUrl('test/getThumb', array('path' => '/uploads' . $v['path'], 'w' => '150', 'h' => '150')) ?>"> <?php endforeach; ?>

图片上传表单：

代码如下	复制代码
<?php if($uploaded):?> <p>File was uploaded. Check <?php echo $dir?>.</p> <?php endif ?> <?php echo CHtml::beginForm('','post',array ('enctype'=>'multipart/form-data'))?> <?php echo CHtml::error($model, 'file')?> <?php echo CHtml::activeFileField($model, 'file')?> <?php echo CHtml::submitButton('Upload')?> <?php echo CHtml::endForm()?>
