Question

我仍在学习创建API以使用Laravel 5.7上传多张图片。当我尝试通过邮递员上传一张图像时，该图像可以存储在数据库中，但是当我尝试上传两个或更多图像时，它不能存储在数据库中。我在邮递员中没有收到这个错误，但在邮递员中预览了重定向到我的登录页面。

这是我的控制者：

         $this->validate($request, [
        'filename.*' => 'image|mimes:jpeg,png,jpg|max:2048'
        ]);

        if($request->hasfile('filename'))
         {
            $images=array();
            foreach($request->file('filename') as $image)
            {
                $photo_name = time().'_'.$request->input('fa_transaction_id').'.png';
                $destinationPath = public_path('/uploads/workphotos');
                $image->move($destinationPath, $photo_name);
                $img_url = asset('/uploads/workphotos/'.$photo_name);

                $data = new FA_Transaction_photo();
                $data->fa_transaction_id = $request->input('fa_transaction_id');
                $data->user_id = $request->input('userid');
                $data->photo_name = $photo_name;
                $data->photo_url = $img_url;
                $data->save();
                array_push($images,$img_url);
            }

有人可以帮助我吗？或任何人都可以教我该怎么做？谢谢

您犯了小错误，请再次检查代码

在循环中返回response（）-> json

所以只有第一张图像被上传和存储，然后请求返回响应

按如下所示更改您的代码：

use Illuminate\Support\Facades\Storage;

$validator = Validator::make($request->all(),
   ['userid'=>'required',
    'fa_transaction_id'=>'required',
    'filename' => 'array',
    'filename.*' => 'image|mimes:jpeg,png,jpg|max:2048'
   ]);

   if($validator->fails())
   {
    return response()->json(['message'=>$validator->errors()->all(),'success'=>0]);
   }

    $trans = FA_transaction::where('fa_transaction_id', $request->fa_transaction_id)->first();

if($trans){
     $this->validate($request, [
    'filename.*' => 'image|mimes:jpeg,png,jpg|max:2048'
    ]);

    if($request->hasfile('filename'))
     {
        $images=array();
        foreach($request->file('filename') as $image)
        {
            $photo_name = time().'_'.$request->input('fa_transaction_id').'.png';
            $destinationPath = public_path('/uploads/workphotos');
            $image->storeAs($destinationPath,$filename);
            $img_url = asset('/uploads/workphotos/'.$photo_name);

            $data = new FA_Transaction_photo();
            $data->fa_transaction_id = $request->input('fa_transaction_id');
            $data->user_id = $request->input('userid');
            $data->photo_name = $photo_name;
            $data->photo_url = $img_url;
            $data->save();
            array_push($images,$img_url);
        }

        return response()->json(['message'=>'Upload Successfully ','success'=>1,'images'=>$images]);

     }else{
      return response()->json(['message'=>'No Files ','success'=>0]);

   }
 }

将此标头添加到邮递员中

Content-Type：multipart / form-data
