Action文件:

 代码如下  
/**
 * TestController.php
 * Created on: 2014-1-26 12:59:36 by Outsider
 */
class TestController extends CController {
 
    /**
     * 缩略图片生成
     * @ path 图片路径
     * @ width 图片宽度
     * @ height 图片高度
     */
    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,
        ));
    }
}
