Laravel 5.3 - 重定向后删除了闪存数据

Question

I am using Laravel 5.3

I have two models, Parent and Student with a many-to-many relationship between them and I want to add a Parent for a Student and vice versa.

My approach was:

1. Create a link from Student profile to add Parent , like so:

   <a href="{{ route('students.parents.add', ['id' => $student->id]) }}" title="Add parent">Add Parent</a>

2. Add the route students.parents.add with a controller method to flash the id to the session and redirect.

    // in web.php: Route::get('/students/{id}/parents/add', ['as' => 'students.parents.add', 'uses' => 'StudentController@addParent']); Route::resource('students', 'StudentController'); // and in StudentsController: public function addParent($id) { return redirect()->route('parents.create')->with('associated_id', $id); } 

   After that, clicking the button redirects to the ParentsController create() but the session data is not there when I try return session()->all() .

Am I missing something?

Make sure you are not adding web middleware in your routes.php file as it is already added in the file RouteServiceProvider.php file.

If you now apply it again in your routes.php, you will see that web appears twice on the route list php artisan route:list . This exactly makes the flash data discard.
