页面未重定向laravel 7

Question

我正在 laravel 上创建简单的 crud 应用程序。一旦添加的数据页面应该重定向到索引页面。但不重定向。到目前为止我做了什么，我附在下面。

添加重定向的记录页面后，我这样写 控制器

   public function index()
{
    $students = Student::all();
    return view('index', compact('students'));      
}  
public function create()
{
    return view('create');
} 
public function store(Request $request)
{
    Student::create([
        'name' => $request->name,
        'phone' => $request->phone,
        'address' => $request->address,
        'created_at' => now(),
    ]);
    $student->save();
    return redirect()->route('students.index')->with('success', 'Student has been added');
}

路线

Route::post('/', 'StudentController@index')->name('student.index');

我得到的错误是未定义变量：学生

index.blade.php 完整代码在这里

@extends('layout')
 
@section('content')
    <div class="row">
        <div class="col-lg-12 margin-tb">
            <div class="pull-left">
                <h2>Laravel 7 CRUD Example from scratch - ItSolutionStuff.com</h2>
            </div>
            <div class="pull-right">
            <a class="btn btn-success" href="{{ route('student.create')}}"> Create New Student</a>
            </div>
        </div>
    </div>
   
    @if ($message = Session::get('success'))
        <div class="alert alert-success">
            <p>{{ $message }}</p>
        </div>
    @endif
  
    <table class="table table-bordered">
        <tr>
            <th>No</th>
            <th>Name</th>
            <th>Phone</th>
            <th>Address</th>

        </tr>
  
        @foreach ($students as $student)
        <tr>
            <td>{{ $student->id  }}</td>
            <td>{{ $student->name }}</td>
            <td>{{ $student->phone }}</td>
            <td>{{ $student->address }}</td>
        </tr>
        @endforeach
    </table>

      
@endsection

Answer 1

你在这里有错误$student->save();当你使用create()时不需要保存

public function store(Request $request)
{
    Student::create([
        'name' => $request->name,
        'phone' => $request->phone,
        'address' => $request->address,
        'created_at' => now(),
    ]);
   
    return redirect()->route('students.index')->with('success', 'Student has been added');
}

您不能重定向到POST 路由。您需要将路由动词更改为GET
