会话登录设置为1,但在重定向时无法识别

what is wrong here:

$('#btnlogin').click(function() {
    var uname = $('#inpuname').val().trim();
    var pass = $('#inpass').val().trim();
    $.post('ad-login-pro.php', {uname, pass}, function(data) {
        console.log(data); // result is 1
        if (data == 1) {location.href = 'ad-start.php';}
    });
});

ad-login-pro.php

$xuname = $_POST['uname'];
$xpass = $_POST['pass'];
$sql = "select status, uname, pass from users where uname = :auname and pass = :apass limit 1";
$st = $db->prepare($sql);
$st->execute([":auname" => $_POST['uname'], ":apass" => $_POST['pass']]);
$row = $st->fetch();
if ($row['uname'] == $xuname && $row['pass'] == $xpass) {
    $_SESSION['login'] = 1;
    $_SESSION['logstatus'] = $row['status'];
    echo $_SESSION['login'];
}

ad-start.php

if (!$_SESSION['login'] == 1) {header('location: ad-login.php');}

This line works, i.e. I'm returning to ad-login.php.

But it shouldn't work because $_SESSION['login'] == 1;

Any idea?

    You should try using session_start():

    Example:

    ad-login-pro.php

    // At the very top of the page
    session_start();
    
    
    $xuname = $_POST['uname'];
    $xpass = $_POST['pass'];
    $sql = "select status, uname, pass from users where uname = :auname and pass = :apass limit 1";
    $st = $db->prepare($sql);
    $st->execute([":auname" => $_POST['uname'], ":apass" => $_POST['pass']]);
    $row = $st->fetch();
    if ($row['uname'] == $xuname && $row['pass'] == $xpass) {
        $_SESSION['login'] = 1;
        $_SESSION['logstatus'] = $row['status'];
        echo $_SESSION['login'];
    }
    

    ad-start.php

    // At the very top of the page
    session_start();
    
    if (!$_SESSION['login'] == 1) {header('location: ad-login.php');}
    

    documentation: http://php.net/manual/en/function.session-start.php
