Laravel :Skipping Validation When Fields Have Certain Values

 You may occasionally wish to not validate a given field if another field has a given value. You may accomplish this using the exclude_if validation rule. In this example, the appointment_date and doctor_name fields will not be validated if the has_appointment field has a value of false:

use Illuminate\Support\Facades\Validator;

 

$validator = Validator::make($data, [

'has_appointment' => 'required|boolean',

'appointment_date' => 'exclude_if:has_appointment,false|required|date',

'doctor_name' => 'exclude_if:has_appointment,false|required|string',

]);

 If we want to apply unique validation when $request->type="register" wen $request->type="forgot_password"  unique validation will be not work. In below eample

  $validator = Validator::make($request->all(), [

                'type' => 'required|in:register,forgot_password',

                'email' => 'exclude_if:type,"forgot_password"|required|unique:users,email'

            ]);
