Validation rules required_if with other condition (Laravel 5.4)

Question

I got a problem with validation rules with nested conditions.

class StoreRequest extends Request
{
        public function authorize(){
        return true;
             


        

Answer 1

Just came across the same problem and found the following answer that seems to work for me:

issue-using-required-if-validation-rule-in-form-builder

     return [
                'type_id'     => 'required|integer',
                'external_id' => 'required_if:type_id,==,3|nullable|integer',
            ];

Result for me:

field not populated, type id not 3 - pass

field not populated, type id 3 - fail - required field

field populated, type id 3, non-integer - fail in integer rule

field populated, type id 3, integer - pass - all good!

note - think nullable rule came in Laravel 5.3
