Code generators are used to generate text codes, which are then sent to phone numbers for verification.

Custom code generator

A code generator implements CodeGeneratorInterface, containing only the generateCode method. The generateCode method must return an instance of \Drupal\sms\PhoneNumberVerification\CodeGenerator\VerificationCode.

The context of the code, including the entity/object it is for, and the phone number, is provided as $context.

namespace Drupal\my_module;

use Drupal\sms\PhoneNumberVerification\CodeGenerator\CodeGeneratorInterface;

final class MyCodeGenerator implements CodeGeneratorInterface {
  public function generateCode(VerificationCodeContext $context): VerificationCodeInterface {
    return new VerificationCode((string) \random_int(100000, 999999));
  }
}
