    if($resim = $request->file("resim"))

            $time = time();
            $resim_isim = $time.".jpg";
            $resim_isim_thumb = "galeri_thumb_".$time.".jpg";
            $resim_isim_large = "galeri_large_".$time.".jpg";
            Image::make($resim->getRealPath())->fit(600,400)->save(public_path("uploads/".$resim_isim_thumb));
            Image::make($resim->getRealPath())->resize(null, 720, function ($constraint) {
                $constraint->aspectRatio();
            })->save(public_path("uploads/".$resim_isim_large));

            $input = [];
            $input["isim"] = $resim_isim;
            $input["imageable_id"] = $proje_id;
            $input["imageable_type"] ="App\Proje";

            $input["sira"] = 0;
            Resim::create($input);



        Session::flash("b_durum",0);
        Session::flash("bilgilendirme","Resim başarıyla yüklendi");

上传多个文件时会出现问题。例如，我想上传 5 个图像文件。在数据库端添加了 5 条记录，但一些图像名称相同。当我控制上传文件夹 3 图像上传但数据库上的图像记录是 5。

上传文件夹中的图像名称是

galeri_large_1479329550.jpg
galeri_large_1479345567.jpg
galeri_large_1479374665.jpg

数据库记录

image name column 
---------------------------
galeri_large_1479329550.jpg
galeri_large_1479329550.jpg
galeri_large_1479345567.jpg
galeri_large_1479345567.jpg
galeri_large_1479374665.jpg

有时上传多个文件时没有问题，但通常会出现此问题。所以我不明白为什么会出现问题。

foreach ($request->file("resim") as $thumbsnail) {
                $thu = time().'.'.$thumbsnail->getClientOriginalExtension();
                Image::make($thumbsnail->getRealPath())->resize(600, 400, function ($constraint) {
                    $constraint->aspectRatio();
                })->save($destinationPath.'/'.$thu);

//Insert to the DB


            }
//Then return response

我在库中找到了这段代码：

key: "_getParamName",
    value: function _getParamName(n) {
      if (typeof this.options.paramName === "function") {
        return this.options.paramName(n);
      } else {
        return "" + this.options.paramName + (this.options.uploadMultiple ? "[" + n + "]" : "");
      }
    }

并写道：

key: "_getParamName",
    value: function _getParamName(n) {
      if (typeof this.options.paramName === "function") {
        return this.options.paramName(n);
      } else {
        return "" + this.options.paramName;
      }
    }

这对我有用！
