How to send a value to server with post method?

I'm working with JS from the last few days, and I'm implementing chat feature. I am using AJAX post method to send and receive texts,but the problem is that the code I've written isn't working well.

JS code

function getPeople(room_code) {
    console.log(room_code);
    $.ajax({
        url: "process_php/Getroompeople.php" , 
        data: {
            roomcode: room_code
            } ,
        cache: false ,
        processData: false ,
        type: "POST" ,
        success: function(response) {
            //implementPeople(response);
            console.log(response);

        }
    });

        setTimeout(function(){ getPeople(room_code); }, 1000);
    }

PHP code

<?php
$room_code = $_POST["roomcode"];
echo $room_code;
echo "hello";
?>

The response says undefined index.

So, any help with that would be very helpful to me!

Thanks in Advance!

You are passing an object to data.

    data: {
        roomcode: room_code
        } ,

Under normal circumstances, jQuery will process this object and convert it into the application/x-www-form-urlencoded data format.

PHP will automatically parse application/x-www-form-urlencoded data and use it to populate $_POST.

However, you also said:

   processData: false ,

… which tells jQuery not to process it. So it will get treated as a plain string (i.e. "[object Object]") and sent to PHP.

Your data doesn't exist in that string, so $_POST["roomcode"] isn't defined.

Remove processData: false , (or set it to true)

Try setting "processData" to true.
