Laravel: validate an integer field that needs to be greater than another

Question

I have two fields that are optional only if both aren\'t present:

$rules = [
  \'initial_page\' => \'required_with:end_page|integer|min:1|digits_between:          


        

Answer 1

If you're maintaining a project on Laravel 5.2 then the following should backport the current gt rule for you:

class AppServiceProvider extends ServiceProvider
{
  public function boot()
  {
    Validator::extend('gt', function($attribute, $value, $parameters, $validator) {
      $min_field = $parameters[0];
      $data = $validator->getData();
      $min_value = $data[$min_field];
      return $value > $min_value;
    });   

    Validator::replacer('gt', function($message, $attribute, $rule, $parameters) {
      return sprintf('%s must be greater than %s', $attribute, $parameters[0]);
    });
  }
}

You can then use it as per the current documentation:

$rules = [
  'end_page' => 'gt:initial_page'
];
