Question

尝试创建新目录时出现此错误。我不明白的是，当我使用$folderGallery = mkdir($dir.$modelGallery->gallery_id, 0777, true);时，它不起作用，但是当我更改为$modelGallery->gallery_name时，它已成功创建。

$session = Yii::$app->session;

$modelGallery= new Gallery();

//die(count($modelEulogy));

if ($modelGallery->load(Yii::$app->request->post())) 
{
    if($modelGallery->validate())
    {
        $dir = 'img/'.$session['UserID'].'/album/';

        //die($modelGallery->gallery_id);

        if(!file_exists($dir))
            $folderGallery = mkdir($dir.$modelGallery->gallery_id, 0777, true);
        else
            $folderGallery = mkdir($dir.$modelGallery->gallery_id, 0777, true);


        //$model->gallery_id = $id;
        $modelGallery->user_id = $session['UserID'];
        $modelGallery->date = date("Y-m-d H:i:s");
        $modelGallery->save();
    }
    return $this->redirect(['index', 'gallery_id'=>$id]);
}

Answer 1

您必须检查现有目录

$path = $dir.$modelGallery->gallery_id;
if (!is_dir($path)) {
    mkdir($dir.$modelGallery->gallery_id, 0777, true);
}

Answer 2

您可以使用FileHelper::createDirectory()-它会为您做任何必要的检查。您还应该使用绝对路径，以避免路径解析不明确：

$dir = '@webroot/img/'.$session['UserID'].'/album/';
FileHelper::createDirectory(Yii::getAlias($dir . $modelGallery->gallery_id, 0777, true));

mkdir（）：文件存在（Yii2）
