Form in Laravel don't send data - laravel

Question

I try to make a form with multiples date inputs, I copy the model from the register / login blade template but it don't work, here is what I do in my template:
<form method="POST" action="{{ route('createDispo') }}">
#csrf
<div class="form-group row">
<label for="date_debut" class="col-md-4 col-form-label text-md-right">Date de début</label>
<div class="col-md-6">
<input type="date" name="date_debut" class="form-control" required>
</div>
</div>
<div class="form-group row">
<label for="date_debut_heure" class="col-md-4 col-form-label text-md-right">Heure de début</label>
<div class="col-md-6">
<input type="date" name="date_debut_heure" class="form-control" required>
</div>
</div>
<div class="form-group row">
<label for="date_fin" class="col-md-4 col-form-label text-md-right">Date de fin</label>
<div class="col-md-6">
<input type="date" name="date_fin" class="form-control" required>
</div>
</div>
<div class="form-group row">
<label for="date_fin_heurev" class="col-md-4 col-form-label text-md-right">Heure de fin</label>
<div class="col-md-6">
<input type="date" name="date_fin_heure" class="form-control" required>
</div>
</div>
<div class="form-group row mb-0">
<div class="col-md-6 offset-md-4">
<button type="submit" class="btn btn-primary">
Ajouter
</button>
</div>
</div>
</form>
But the form doesn't return a $data array like the register or login one, but only the first value (date_debut and not in an array, how to properly do a form with Laravel ?
EDIT:
Here is my controller
public function createDispo(array $data){
$disponibilite = new Disponibilite();
$disponibilite->date_debut = $data["date_debut"];
$disponibilite->date_fin = $data["date_fin"];
//$user->disponibilites()->save($disponibilite);
}
The problem is that I don't receive this 'data' array but only one value (the first datepicker)

Answer 1

You can access submitted data using the $request. The docs describe it well. In your case:
use Illuminate\Http\Request;
public function createDispo(Request $request){
$disponibilite = new Disponibilite();
$disponibilite->date_debut = $request->date_debut;
$disponibilite->date_fin = $request->date_fin;
// ...
}

Answer 2

When you send HTTP requests as this form, the method that should get this information should receive the Illuminate/Http/Request class.
The controller login does that differently because the controller send the $request->all() (this is an array) to the method login after the validation.
So what you have to do, is to change:
public function createDispo(array $data){
To
public function createDispo(Request $data){
Or to be more consistent to variables:
public function createDispo(Request $request){
Then you can access the data with:
public function createDispo(Request $request){
$disponibilite = new Disponibilite();
$disponibilite->date_debut = $request->date_debut;
$disponibilite->date_fin = $request->date_fin;
//$user->disponibilites()->save($disponibilite);
}
Remember to import the class of Illuminate\Http\Request when using Request
