Laravel - Validation - Rule Required If
The field under validation must be present and not empty if the anotherfield field is equal to any value.
If you would like to construct a more complex condition for the required_if
rule, you may use the Rule::requiredIf
method. This method accepts a boolean or a closure. When passed a closure, the closure should return true
or false
to indicate if the field under validation is required:
use Illuminate\Support\Facades\Validator;
use Illuminate\Validation\Rule;
Validator::make($request->all(), [
'role_id' => Rule::requiredIf($request->user()->is_admin),
]);
Validator::make($request->all(), [
'role_id' => Rule::requiredIf(function () use ($request) {
return $request->user()->is_admin;
}),
]);
