php - 如何创建有效性.php 文件

Question

我一直在尝试将我创建的 home.php 和 login.php 文件链接到我的验证文件，但它不起作用。它显示警告:包括(位置:login.php):无法打开流:第 21 行 C:\xampp\htdocs\userregistration\validation.php 中没有此类文件或目录

<?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';       
}   
?>

好的，在您共享的代码中。我发现一个错字:

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

然后

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