返回 laravel 函数在服务器上不起作用

Question

我的 laravel 项目有问题，当验证器 false 返回函数在 localhost 上运行良好，但在服务器上它返回到 root url 时，有人可以帮我弄清楚吗？我的控制器是这样的：public function update(Request $request, $id){    if ($request->isMethod('get'))        return view('employees.form_edit', ['user' => User::find($id)]);    else {        $rules = [            'name' => 'required',            'full_name' => 'required',            'id_number' => 'required',            'date_of_birth' => 'required',            'avatar' => 'mimes:jpeg,jpg,png,gif|max:2048'        ];        $validator = Validator::make($request->all(), $rules);        if ($validator->fails()) {            return redirect()->back()                ->withErrors($validator)              ;        }        $user = User::find($id);        $user->name = $request->name;        $user->position = $request->position;        $user->full_name = $request->full_name;        $user->id_number = $request->id_number;        $user->date_of_birth = $request->date_of_birth;        $user->status = $request->status;        $img_current = 'upload/avatar/' .$request->input('img_current');        if (!empty($request->file('avatar'))) {            $file_name = $request->file('avatar')->getClientOriginalName();            $user->image = $file_name;            $request->file('avatar')->move('upload/avatar/',$file_name);            if (File::exists($img_current)) {                File::delete($img_current);            }        }else{            echo "no file";        }        $user->save();        return redirect('listEmployees');    }}我的路线：Route::group(['prefix' => 'listEmployees'], function () {  Route::match(['get', 'post'], 'update/{id}', 'EmployeesController@update');});

Answer 1

试试我有的这段代码

控制器

public function update(Request $request, $id)

{

    if ($request->isMethod('get'))

      return view('employees.form_edit', ['user' => User::find($id)]);

    else {

      $_data = $request->validate([

        'name' => ['required'].

        'full_name' => ['required'],

        'id_number' => ['required'],

        'date_of_birth' => ['required'],

        'avatar' => ['mimes:jpeg,jpg,png,gif', 'max:2048'],

        'position' => ['nullable'],

        'status' => ['nullable']

      ])

      $img_current = 'upload/avatar/' .$request->input('img_current');

      if (!empty($request->file('avatar'))) {

          $file_name = $request->file('avatar')->getClientOriginalName();

          $data['image'] = $file_name;

          $request->file('avatar')->move('upload/avatar/',$file_name);

          if (File::exists($img_current)) {

              File::delete($img_current);

          }

      }else{

          echo "no file";

      }

      $user = User::find($id);

      $user->update($_data);

      return redirect('listEmployees');

    }

}

看法

@if ($errors->any())

  <div class="alert alert-warning">

    @foreach ($errors->all() as $error)

      {{$error}} <br>

    @endforeach

  </div>

@endif

我通过将重定向功能更改为来解决这个问题

 return redirect()->action( 
                'EmployeesController@update', ['id' => $id]
            )

谢谢大家

在进一步解决这个问题之前，您需要稍微清理一下代码。首先，您不需要检查request->method您是否已经制作了路线“Route::update”（laravel 会处理它）。第二：使用 laravel form-request 并使你的控制器更干净和可读（php artisan make:request ModelNameRequest）第三：如果你想重定向到back()，你不需要手动重定向用户，laravel 再次处理它，back()如果验证器失败，它将重定向和 $errors 数组。这是可能工作的代码的任何方式：

public function update(Request $request, $id)

    {

    $rules = [

        'name' => 'required',

        'full_name' => 'required',

        'id_number' => 'required',

        'date_of_birth' => 'required',

        'avatar' => 'mimes:jpeg,jpg,png,gif|max:2048'

    ];

    // if the validation failes, laravel redirects back with a collection of $errors

    $this->validate($request->all(), $rules);

    // you probably want to use User::create($request->only('input1', 'input2', ...);

    $user = User::find($id);

    $user->name = $request->name;

    $user->position = $request->position;

    $user->full_name = $request->full_name;

    $user->id_number = $request->id_number;

    $user->date_of_birth = $request->date_of_birth;

    $user->status = $request->status;

    $img_current = 'upload/avatar/' .$request->input('img_current');

    // use a good package for storing your files like Mediable to make it easy.

    if (!empty($request->file('avatar'))) {

        $file_name = $request->file('avatar')->getClientOriginalName();

        $user->image = $file_name;

        $request->file('avatar')->move('upload/avatar/',$file_name);

        if (File::exists($img_current)) {

            File::delete($img_current);

        }

    }else{

        //TODO: you should not echo some thing here, you should use session()->flash()

        session()->flash('message', 'You did not select any file.');

    }

    $user->save();

    return redirect('listEmployees');

}
