Question

我想将图像上传到 laravel 中的公用文件夹和数据库中，但是我遇到了一些问题，Image is uploading into public folder but image is not saving into database.有人可以帮我说一下哪里出了问题吗？这是我的代码。

控制器

public function clientaction(Request $request)
   {


        $validation = validator::make($request->all(),[
          'select_file' =>'required|image|mimes:jpeg,png,jpg,gif|max:2048'
        ]);
        if($validation->passes())
        {
         $image = $request->file('select_file');
         $new_name = rand() . '.' . $image->getClientOriginalExtension();
         $image->move(public_path('images'), $new_name);
         return response()->json([
          'message'   => 'Image Upload Successfully',
          'class_name'  => 'alert-success'
         ]);


        }
        else
         {
          return response()->json([
          'message'   => $validation->errors()->all(),
         'class_name'  => 'alert-danger'
      ]);
     }

     DB::table('logo-clients')->insert([

      'select_file'=> $new_name
  ]);
   }

路线

Route::get('DashBoard','AdminController@DashBoard');


Route::get('Clients','AdminController@clients');
Route::post('/ajax_upload/action','AdminController@clientaction')->name('ajaxupload.action');

Answer 1

因为您已经在返回值，这意味着之后的操作没有用

所以您只需要移动

DB::table('logo-clients')->insert([

  'select_file'=> $new_name
]);

在这部分下面

$image->move(public_path('images'), $new_name);
//move it into here

Answer 2

因为您已通过验证return。请查看您通过验证并失败后返回两次的代码。我建议您在通过验证后返回response()->json()之前先将代码保存到数据库中，然后移动代码。

Answer 3

将文件移入文件夹后，您的函数将返回。因此不会执行数据库插入代码。您的功能应该像

public function clientaction(Request $request) {

    $validation = validator::make($request->all(),[
      'select_file' =>'required|image|mimes:jpeg,png,jpg,gif|max:2048'
    ]);
    if($validation->passes())
    {
     $image = $request->file('select_file');
     $new_name = rand() . '.' . $image->getClientOriginalExtension();
     $image->move(public_path('images'), $new_name);
    }
    else
     {
      return response()->json([
         'message'   => $validation->errors()->all(),
         'class_name'  => 'alert-danger'
      ]);
    }

 DB::table('logo-clients')->insert([

  'select_file'=> $new_name ]); 

return response()->json([
      'message'   => 'Image Upload Successfully',
      'class_name'  => 'alert-success'
     ]);
 }
