发布表单时，Laravel Route资源不会更新

Question

I am using Laravel 5.6 and MySQL. I am going to update the student table using the following controller function:

public function update(Request $request, $id)
    {
        $students = Student::find($id);
        $students->name = $request->input('name');
        $students->town = $request->input('town');
        $students->save();
 } 

and the update form action looks like this:

<form action="{{route('student.update',$students->id)}}" method="POST">
    {{csrf_field()}}

and my route is define like this:

Route::resource('student','StudentController');

My problem is, when I click the update button in the form it generates the following error message

1/1) MethodNotAllowedHttpException

What's wrong?

Answer 1

You are using wrong HTTP method, update method on Route::resource route requires that request is sent with PUT/PATCH HTTP method.

Since HTTP forms doesn't support PUT/PATCH as method you should spoof HTTP method by using Blade directive @method('PUT') inside form.

<form action="{{route('student.update',$students->id)}}" method="POST">
    {{csrf_field()}}

    {!! @method('PUT') !!}
</form>
