强文本

当我dd（$ request-> all（））;在控制器的存储功能中，我得到了所有其他值，但没有图像。。当我dd（）时，它甚至不显示image = null。 array：8 [“ _token” =>“ C27oLkk8wDTcBnZDA38nPCte4SY18HqXqxcFDcrI”“ name” => null“ dateofbirth” => null“ gender” =>“ Male”“地址” => null“ email” => null“ phone” => null “ course” => null]

我正在使用ajax请求，尽管我输入了图像，但显示该图像是必需的。我在这里做错什么了？

       $validator = Validator::make($request->all(), [
    'name' => 'required|min:2',
    'dateofbirth' => 'required|date',
    'gender' => 'required',
    'address' => 'required',
    'email' => 'required|email',
    'phone' => 'required|numeric',
    'course' => 'required',
    'image' => 'required|image|mimes:jpeg,png,jpg',
]);

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

 $name = $request['name'];
$dateofbirth = $request['dateofbirth'];
$gender = $request['gender'];
$address = $request['address'];
$email = $request['email'];
$phone = $request['phone'];
$course = $request['course'];

if($request->hasFile('image')) {
    $img_name = time() . '.' .$request->file('image')->getClientOriginalExtension();
    $destinationPath = public_path('/assets/images/');
    $request->file('image')->move($destinationPath, $img_name);
    $image = $img_name;
}

Student::create([
    'name' => $name,
    'dateofbirth' => $dateofbirth,
    'gender' => $gender,
    'address' => $address,
    'email' => $email,
    'phone' => $phone,
    'course' => $course,
    'image' => $image,
]);

Answer 1

您可以尝试

$validator = Validator::make($request, [
    'name' => 'required|min:2',
    'dateofbirth' => 'required|date',
    'gender' => 'required',
    'address' => 'required',
    'email' => 'required|email',
    'phone' => 'required|numeric',
    'course' => 'required',

    'image' => 'required|file|mimetypes:image/jpeg,image/png',
]);


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

//store image 
$path = $request->image->store('images'); 
//it will store your images at `storage/app/public/images` folder with dynamically generated image name, be sure create images folder there


Student::create([
    'name' => $request->name,
    'dateofbirth' => $request->dateofbirth,
    'gender' => $request->gender,
    'address' => $request->address,
    'email' => $request->email,
    'phone' => $request->phone,
    'course' => $request->course,
    'image' => $path,
]);

从命令行执行此命令

php artisan storage:link

它将创建storage/app/public到public/storage文件夹的符号链接。

现在您可以在这样的视图中使用图像

{{asset('storage/images/test.jpeg')}}

如果您必须在控制器中读取该文件，则可以像这样使用它

Storage::disk('public')->get('images/test.jpeg');

始终将文件存储在存储文件夹中。所有公共文件都应存储在storage/app/public
