Answer 1

Yes. I know of at least two ways.

// option one: 'in' takes a comma-separated list of acceptable values
$rules = [
    'field' => 'in:hello',
];

// option two: write a matching regular expression
$rules = [
    'field' => 'regex:^hello$',
];

Actually, I don't remember if you need the ^$ delimiters in the regex, but it's easy to find out by trying it. :)

Method updated for Laravel 5.5. https://laravel.com/docs/5.5/validation#rule-in

// 'in' takes an array of values

$rules = [
    'field' => [ Rule::in('hello')]
];

Use Rule; namespace in your controller to access Rule class (Illuminate\Validation\Rule)
