Answer 1

Maybe you wrote request instead of required? Like here:
$data = $request->validate([
'field' => 'request|string|max:255',
]);
Trying to fire validateRequest method suggest you were trying to use 'request' validation rule which doesn't exist.
All valid rules you can find here, but I think you just made a typo.

Answer 2

You should use a Validator facade class
In you Controller
use Validator;
See link Laravel validation

Answer 3

You can validate the form as below:
public function formSubmit(Request $request){
$request->validate([
'name' => 'required',
'address' => 'required',
'phone' => 'required',
]);
$customer =Customer::insert([
'name' => $request->name,
'address' => $request->address,
'phone' => $request->phone
]);
dd($customer);
echo "Data send Successfully";
}

Answer 4

you may try this method
$request->validate([
'sex' => ['required',Rule::in('f','m')]
]);
this one is worked for me

Answer 5

$request-> validate([
'name'=>'required',
'email'=>'required|email'|'unique:admins',
'password '=>'required|min:5|max:12'
After how many minutes of debugging the error was there's an extra '' in required and a space after 'password '. Please see corrected code below
$request-> validate([
'name'=>'required',
'email'=>'required|email|unique:admins',
'password'=>'required|min:5|max:12'

Answer 6

In my case, I forget to import Validator file and just added this line at the top of controller file where I was using Validator in function
use Illuminate\Support\Facades\Validator;
and it worked like a charm.

Answer 7

In my case I just misspelled required a few times.
