here are the code
Login form
<?php include "header.php";
include "function.php";

require('db.php');
session_start();
// If form submitted, insert values into the database.
if (isset($_POST['button'])) {
$name = ($_REQUEST['name']);
$password = ($_REQUEST['password']);
mysqli_real_escape_string($con, $name);
mysqli_real_escape_string($con, $password);

//Checking is user existing in the database or not
$query = "SELECT * FROM `user` WHERE name='$name' and password='$password'";
$result = mysqli_query($con,$query) or die(mysql_error());
$rows = mysqli_num_rows($result);

if($rows==1){
$details = $result->fetch_array();
$_SESSION['name'] = $details['name'];
$_SESSION['user_id'] = $user_id = $details['user_id'];

$code = randomActivate();
$realcode = active_exist($code);
$insert = "INSERT INTO otp VALUES(NULL,'$realcode', '$user_id' )";
$result = mysqli_query($con,$insert) or die(mysql_error());
sms ('Otp',$details['phone'],'Your otp code is'. " ".
