Yii：有什么方法可以以压缩形式保存图像？

Question

我有很大的图片，我想在将它们保存到数据库之前压缩它们。这是我的控制器，有没有办法不用任何扩展就可以做到这一点？

public function actionCreate()
{
    $model = new Business;
    if (isset($_POST['Business'])) {
        $rnd = rand(0, 9999);

        $model->attributes = $_POST['Business'];

        $uploadedFile = CUploadedFile::getInstance($model, 'image');
        $fileName = "{$rnd}-{$uploadedFile}";

        $model->image = $fileName;
        if ($model->save()) {
            $uploadedFile->saveAs(Yii::app()->basePath . '/../img/' . $fileName);
            $this->redirect(array('view', 'id' => $model->id));
        }
    }

    $this->render('create', array(
        'model' => $model,
    ));
}

1) 您需要下载 this 扩展并像在文档中那样在配置中连接它。 2) 上传原始文件后，您只需调用方法resize()。它是作品。我查过了。在您的情况下，它将是这样的：

public function actionCreate()
{
    $model = new Business;
    if (isset($_POST['Business'])) {
        $rnd = rand(0, 9999);

        $model->attributes = $_POST['Business'];

        $uploadedFile = CUploadedFile::getInstance($model, 'image');
        $fileName = "{$rnd}-{$uploadedFile}";

        $model->image = $fileName;
        if ($model->validate()) {
           $path = Yii::app()->basePath . '/../img/' . $fileName;

           $uploadedFile->saveAs($path);

           $image = new EasyImage($path);
           $thumbPath = Yii::app()->basePath . '/../thumb/' . $fileName;

           $image->resize(100, 100);
           $image->save($thumbPath);

           $model->save();
           $this->redirect(array('view', 'id' => $model->id));
       }
   }

   $this->render('create', array(
       'model' => $model,
   ));
}
