Laravel validator for input arrays

Question

First and foremost:

I did read both entries @ laravel and stackoverflow

I am trying to validate an array containing input[text]. They are defined currently as:

<input type='text' name='user[0][name]'/><div>@error('user[0][name]'){{ $message }}@enderror</div>
<input type='text' name='user[1][name]'/><div>@error('user[1][name]'){{ $message }}@enderror</div>

I tried the 3 variants below as well:

<input type='text' name='user[][name]'/>
<input type='text' name='name[]'/>
<input type='text' name='name[0]'/>

My ExampleController does this, in the store() method:

    $validator = Validator::make($request->all(), [
        'user.*.name' => 'required|string',
    ])->validate();

I've also tried using:

    $validatedData = $request->validate([
        "user.*.name"    => "required|string",
    ]);//*/

The other option that I've tried to use to match was (for the other case):

    'name.*' => 'required|string',

None of these manage to print an error message in the div that follows the input.

The only way for me to get to see the error, is if I do the validation in of the two below (for each case):

"user[0][name]"    => "required|string",
"name[0]"          => "required|string",

So... what is it that I'm doing wrong?

user[0][name] is the correct syntax for naming your form input elements.

To access the error message(s), however, use dot notation: user.0.name.

Here's a working playground.
