Laravel passing user id to view/controller - php

Question

I am fairly new to laravel and I have implemented a system in my project so that user can send "dm's" to eachother. But now in the create view there are checkboxes where you can check the users you want to send a dm to. I get the users like this in my create function in my controller:
$users = User::where('id', '!=', Auth::id())->get();
My goal is that users can click on other users names in other views and select an option with "send dm" or something. But I have no Idea how I can pass that id to my create function in my controller. Should I make the checkboxes hidden and select the id that is passed? Or what should my gameplan be here?
This is my create function in my controller
public function create($userid)
{
$users = User::where('id', '=', $userid);
return view('messenger.create', compact('users'));
}
These are my routes:
Route::group(['prefix' => 'messages'], function () {
Route::get('/', ['as' => 'messages', 'uses' => 'MessagesController#index']);
Route::get('create/{userid}', ['as' => 'messages.create', 'uses' => 'MessagesController#create']);
Route::post('/', ['as' => 'messages.store', 'uses' => 'MessagesController#store']);
Route::get('{id}', ['as' => 'messages.show', 'uses' => 'MessagesController#show']);
Route::put('{id}', ['as' => 'messages.update', 'uses' => 'MessagesController#update']);
});
The problem is I don't know how to fill up that $userid in my create function.
But I am not sure this is the correct way to do it, I think I might be on a completely wrong path here
Could realy use all the help
Thanks in advance!

Answer 1

If you want to use links and send a single user a dm here is an approach. You need a view for the dm and view with the user.
Here is the user:
<a href"{{ route('createMessage', ['user_id' => $user->id]) }}">Send message to: {{ $user->name }}</a>
You send user_id as route parameter that holds the id of the user that you want to send a message to ($user->id).
Here is the route:
Route::get('/message/create/{user_id}', [
'uses' => 'UsersController#create',
'as' => 'createMessage'
]);
You get the route parameter user_id in your create methond in your controller like so:
public function create($user_id)
{
$user = User::find($user_id);
return view('messenger.create', ['user' -> $user]);
}

Try this :
Your routes :
Route::get('create/{userid}', ['as' => 'messages.create', 'uses' => 'MessagesController#createForm']); // to load the form
Route::post('create/{userid}', ['as' => 'messages.create', 'uses' => 'MessagesController#create']); // to create the DM
To load the form with the user information :
public function createForm($userid)
{
$user = User::find($userid);
return view('messenger.create', array("user" => $user));
}
You can passe the ID on the URL in the action attribute for example :
<form action="create/{{ $user->id }}" method="POST">
The method to create the DM:
public function create($userid)
{
$user = User::find($userid);
//create the DM
}
There is another solution, you can pass on with a hidden input
