我可以在Laravel 5请求验证中对字段组应用相同的规则吗？

Question

I am using laravel request form validation and I want to apply same rule for more than one field.Is it possible for in any simple way? or need to write code for individually. My validation rule given below.

  protected $rules = [
    'phone' => ['max:11'],
    'work_phone' => ['max:11'],
    'mobile' => ['max:11'],
];

Can I group these filed in to single rule?

You can do some things inside the rules() method:

public function rules(){
    $phoneRules = ['max:11'];
    return [
        'phone' => $phoneRules,
        'work_phone' => $phoneRules,
        'mobile' => $phoneRules
    ]
}

Or:

public function rules(){
    $fields = ['phone', 'work_phone', 'mobile'];
    return array_fill_keys($fields, ['max:11']);
}

In case you have other attributes to validate with other rules you'd need something like this:

public function rules(){
    $fields = ['phone', 'work_phone', 'mobile'];
    $phoneRules = array_fill_keys($fields, ['max:11']);
    $otherRules = [
        'foo' => 'required',
        'bar' => 'min:30'
    ]
    return array_merge($phoneRules, $otherRules);
}
