PHP not reciving data with AJAX's POST

Question

I have to say I saw a dozens of topics similar to my problem, but most of them were typos or spelling.

My PHP file does not seem to receive any data from AJAX POST function (I'm getting Undefined Index). Here is my code:

var login = $("#log_l").val();
var pwd = $("#pwd_l").val();
alert(login);
alert(pwd);
$.ajax({
    type: "POST",
    url: 'app/menu/login.php',
    data: {
        login1: login,
        pwd1: pwd,
    },
    cache: false,
    success: function (data) {
        if (data == 'fail') {
            alert('test2');
            $('#failure_log').show();
        }
        else {
            document.location = " {$conf->action_root}postlogin";
        }
    }
});
return false;

And the login.php:

$login = $_POST['login1'];
$haslo = $_POST['pwd1'];
...

I tried with both:

login1:login,
pwd1:pwd,

And:

'login1':login,
'pwd1':pwd,

But in both ways I receive "Undefined index" error in .php file on 'login1' and 'pwd1' variables. I checked that ajax 'reaches' file and it even receives the echos from .php file, but the variables are not sent/received.

Do you have any ideas what might be wrong?

You need to use file_get_contents to capture ajax calls or you need to define. Check this

Or

you need to set the ajax call as form_encoded_url contentType: "application/x-www-form-urlencoded",
