I am using this function You may use it like something like bellow
$voucher->code = $this->generateRandomString(6);// it should be dynamic and unique public function generateRandomString($length = 20) { $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'; $charactersLength = strlen($characters); $randomString = ''; for ($i = 0; $i < $length; $i++) { $randomString .= $characters[rand(0, $charactersLength - 1)]; } return $randomString; }
