I 've been working on a laravel 5.7 blog project. I want to comment an article. I need to achieve this:

• Before logging in, I can type anything in comment textarea.




• I submit comment(of course it would be intercepted by auth
  middleware),




• then I'm redirected to login page,




• After logging in, **I hope my app could submit previous form
  data(or comment) automaticlly instead of typing the same comment again.



• I think that's a very common bussiness logic in many websites nowdays,
  but how am I supposed to achieve this?

My comments controller here:

public function __construct()

 $this->middleware('auth');


public function store(Post $post)
 $comment = Comment::create([
 'body' => session('comment')?:request('body'),
 'post_id' => $post->id,
 'user_id' => auth()->user()->id 
 //before logging in, you don't have an user_id yet.
 ]); 
 return back()->with('success', 'Add comment succeeded');

web.php Route here:

Route::post('/posts/post/comments', 'CommentsController@store')->name('addComment');

Basiclly auth middleware intercepted my form data submit, I want to go across the auth middleware with my form data. Not lost them after logging in.

I think the solution to your problem is here:
https://laravel.com/docs/5.7/session#storing-data

Here is the solution.A little tricky.Save comment to the session first before go to auth middleware.After logging in, GET that route to create comment.
Route:

Route::get('/posts/post/comments', 'CommentsController@store')->name('addComment');
Route::post('/posts/post/comments', 'CommentsController@commentSave');

Comments controller:

public function __construct()

 $this->middleware('auth', ['except' => ['commentSave']]);

public function commentSave(Request $request)
 $url = URL::previous();
 session(['comment' => $request->input('body')]);
 return redirect("$url/comments");
 

public function store(Post $post)
 if(session('comment'))
 $comment = Comment::create([
 'body' => session('comment'),
 'post_id' => $post->id,
 'user_id' => auth()->user()->id
 ]);
 session(['comment' => null]);
 return redirect("posts/$post->id")->with('success', 'Add comment succeeded');
 
 return redirect("posts/$post->id");
