如何创建validity.php文件

Question

I have been trying to link the home.php and login.php file i created to my validation file but it is not working. It is showing Warning: include(location:login.php): failed to open stream: No such file or directory in C:\xampp\htdocs\userregistration\validation.php on line 21

<?php 
session_start();
$con = mysqli_connect('localhost','root','');
mysqli_select_db($con, 'userregistration');
$name = $_POST['user'];
$pass = $_POST['password'];
$s = " select * from usertable where name = '$name' && password='pass'";
$result = mysqli_query($con, $s);
$num = mysqli_num_rows($result);
if($num == 1){
    include 'location:home.php';
}else{
    include 'location:login.php';       
}   
?>

Ok, so in the code you shared. I found a typo:

                                                          // missed $ in $pass
    $s = " select * from usertable where name = '$name' && password='pass'";

Then

    if ($num == 1) {
        ("home.php"); //<-- here try: header("location:./home.php");
    } else {
        ("login.php"); //<-- here try: header("location:./login.php");
    }
