Employee form validaton? (Date, and mobile number)

@shivamyadav

1st : I want something like that employee age must be 18 or greater than 18 years

You can do it easily by:

'dob' => [
    'required',
    'date',
    'before_or_equal:' . now()->subYears(18)->format('Y-m-d')
],

2nd : I want to add a mobile number validation for every country and with country code.

You need to depend on the package. For example:

• Propaganistas/Laravel-Phone: Phone number functionality for Laravel

Then you can easily like this:

'mobile' => [
    'required',
    'phone:AUTO',  // AUTO will detect the country from the input or you can specify specific countries like 'phone:US,IN'
],
