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
