Laravel 5.6出生日期验证

Question

I created validation rules in my Member Model with date of birth NOT being required. However, when someone does fill in their date of birth, I want it to be 1. in the correct format and 2. the date cannot be a date in the future.

However, when I fill out my form and leave date of birth empty, I still get the following error:

Here my basic Member.php model:

use Esensi\Model\Model;

class Member extends Model
{
    protected $rules = [
        'name' => 'required|alpha|min:2|max:255',
        'surname' => 'required|alpha|min:2|max:255',
        'id_number' => 'required|unique:members,id_number|digits:13',
        'mobile_number' => 'required|digits:10',
        'email' => 'required|email',
        'date_of_birth' => 'date_format:Y-M-D|before:today',
    ];
}

Here's my MemberController.php store function:

public function store(Request $request) 
{
    $member = new Member;
    $member->name = $request->name;
    $member->surname = $request->surname;
    $member->id_number = $request->id_number;
    $member->mobile_number = $request->mobile_number;
    $member->email = $request->email;
    $member->date_of_birth = $request->date_of_birth;

    if(!$member->save()){
        $errors = $member->getErrors();

         return redirect()
            ->action('MemberController@create')
            ->with('errors', $errors)
            ->withInput();
}
//successful creation
    return redirect()
        ->action('MemberController@index')
        ->with('message', '<div class="alert alert-success">Member Created Successfully!</div>');

}

How do I fix it so that date of birth only shows an error when the field is actually filled in but the formatting is incorrect?

Answer 1

'date_of_birth' => 'nullable|date_format:Y-m-d|before:today',
