API

router.post("/add_customer", (req, res) => {
  const sql = `INSERT INTO customer (name, mobile, email, address, state, city, policytype, insurer, renewdate) VALUES (?)`;
  bcrypt.hash(req.body.password, 10, (err, hash) => {
    if (err) return res.json({ Status: false, Error: "Query Error" });
    const values = [
      req.body.name,
      req.body.mobile,
      req.body.email,
      req.body.address,
      req.body.state,

      req.body.policytype,
      req.body.insurer,
      req.file.filename,

AXIOS API -

const [customer, setCustomer] = useState({
  name: "",
  mobile: "",
  email: "",
  address: "",
  state: "",
  city: "",
  policytype: "",
  insurer: "",
  renewdate: "",
});

const navigate = useNavigate();

const handleSubmit = (e) => {
  e.preventDefault();
  const formData = new FormData();
  formData.append("name", customer.name);
  formData.append("mobile", customer.mobile);
  formData.append("email", customer.email);
  formData.append("address", customer.address);
  formData.append("state", customer.state);
  formData.append("city", customer.city);
  formData.append("policytype", customer.policytype);
  formData.append("insurer", customer.insurer);
  formData.append("renewdate", customer.renewdate);

  axios
    .post("http://localhost:3000/employee/add_customer", formData)
    .then((result) => {
      if (result.data.Status) {
        navigate("/employeedashboard/customer");
      } else {
