Comment with Auth in laravel - php

Question

I want the user to only post a comment when logged in. Otherwise a massege appears 'You must be logged in to post a comment'. If I logged in it works if not it doesnt just redirect back!
I solved it. The problem was that the PostCommentsController was in the admin middleware where you have to logged in to see If you are an admin. And if you not logged in redirect to index.
the Controller:
public function store(Request $request)
{
if (Auth::check()) {
$user = Auth::user();
$data = [
'post_id' => $request->post_id,
'author' => $user->name,
'email' => $user->email,
'body' => $request->body
];
Comment::create($data);
$request->session()->flash('comment_success','Your comment have been submited and is waiting moderation');
return redirect()->back();
} else {
$request->session()->flash('login','You must be logged in to post a comment');
return redirect('/login')->back();
}
}

public function store(Request $request)
{
if (!Auth::check()) {
$request->session()->flash('login', 'You must be logged in to post a comment');
return redirect()->back();
}
$user = Auth::user();
$data = [
'post_id' => $request->post_id,
'author' => $user->name,
'email' => $user->email,
'body' => $request->body
];
if (Comment::create($data)) {
$request->session()->flash('comment_success', 'Your comment have been submitted and is waiting moderation');
return redirect()->back();
}
$request->session()->flash('comment_error', 'Your comment does not submited. Try again!!');
return redirect()->back();
}

In your else statement, just use this code return redirect('/login'); using back() function will redirect user back.

Laravel has the built in Auth system, if you use that you can use constructors like the example from my project.
public function __construct()
{
$this->middleware('auth');
}
This just says that the user cannot access any of the methods in this class without being logged in. If they are not logged in it will redirect them back to the login page. You can also have, in your views, #auth and #guest. I use this to show info on private information e.g. private servers can only be seen by the logged in user.
