Validating not all fields in form - Laravel - laravel

Question

In laravel, I have created a form. At the moment, I am working on the validation of the input fields of this form. I ran into a problem when I tried to validate some input fields and others not. For example, mail should be validated but catering_name not (it isn't necessary to fill in this field, its an option)
I have tried all validation methods I could find. I keep getting the same error.
Method Illuminate\Validation\Validator::validatePhone does not exist.
I guess I am missing something.
I have tried:
Validator::make($request->...
$this->validate(request(), [ ...
$request->validate([ ...
Bellow, you will find all the data that should be inputted in the database.
If I remove the validation part, the data got inserted into the database. I think the problem lays with how I try to validate. Thanks for any help.
$this->validate(request(), [
'add_name' => 'required|min:3',
'add_mail' => 'required|email',
'name' => 'required|min:3',
'email' => 'required|email',
'telefone' => 'numeric|phone',
'gsm' => 'numeric|phone',
'event' => 'required|min:3',
'date_start' => 'required|date|after:tomorrow',
'date_end' => 'required|date|after_or_equal:event_date_start',
'location' => 'required|min:3',
'number' => 'required',
]);
$event = new Event;
$event->add_name = request('add_name');
$event->add_mail = request('add_mail');
$event->name = request('name');
$event->email = request('email');
$event->telefone = request('telefone');
$event->gsm = request('gsm');
$event->name = request('name');
$event->date_start = request('date_start');
$event->date_end = request('date_end');
$event->location = request('location');
$event->number = request('number');
$event->catering = request('catering');
$event->catering_name = request('catering_name');
$event->remarks = request('remarks');
$event->status = Event::STATUS_0;
$event->save();

Unfortunately phone is not one of the default validation. You can try something like:
[
'telefone' => 'required|regex:/(01)[0-9]{9}/',
]
You can see the available list of validations given by Laravel here.
There are a wide variety of more complex options depending on how important it is to you.
There are packages for easy plug and play like Laravel-Phone.
You can create your own custom validation using php artisan make:rule phone_number and then editing the new rule made:
namespace App\Rules;
use Illuminate\Contracts\Validation\Rule;
class PhoneNumber implements Rule
{
/**
* Determine if the validation rule passes.
*
* #param string $attribute
* #param mixed $value
* #return bool
*/
public function passes($attribute, $value)
{
// logic here, most likely some sort of regex.
}
/**
* Get the validation error message.
*
* #return string
*/
public function message()
{
return 'The :attribute must be a valid phone number.';
}
}
