AJAX multiple values inside PHP Echo

Question

I'm struggeling with making an AJAX url inside of an php echo. Other troubleshooters around the internet didn't get me through it. Here is my code:

<script type="text/javascript">
    $(document).ready(function () {
        $.ajaxSetup ({
            cache: false
        });

        var ajax_load = "";

        $( "#'.$row_items['id_aanbod'].'" ).change(function() {
            $("#res").html(ajax_load).load("update.php", "e=" +             $("#'.$row_items['id_aanbod'].'").val() & "id=" + $("#hrr").attr("id"));
        });
    });
</script>


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>

The strange thing is that if I use only one variable the script works like it should, but as soon as I insert the second part there is nothing happening. Can anyone help me with this?

Where is $row_items['id_aanbod'] coming from? A database result? You should <?php echo $row_items['id_aanbod'];?> inside the jquery selector. — jvv

Why not just read the documentation for load, and you'll see that it doesn't accept a second argument consisting of a querystring. If you want to send data, add it to the url. — adeneo

wheres the error, how is it not working? errors in dev console? are php errors turned on? — atmd

the "&" has to be inside the string?! Something like: "$("#res").html(ajax_load).load("update.php", "e=" + $("#'.$row_items['id_aanbod'].'").val() + "&id=" + $("#hrr").attr("id"));"... maybe? — ThatMSG

@adeneo I'm pretty sure you can use a query string there. As it is a short-hand method for $.ajax() with some added functionalities, the data parameter can be both a query string (correctly encoded obviously...) or an object. — jeroen

& "id="

should be

+ "&id="

But for clean code, you could write like below:

$("#<?php echo $row_items['id_aanbod']?>").change(function() {
    $("#res").html(ajax_load).load("update.php", {
      e: this.value,
      id: $("#hrr").attr("id")
    }); 
});

Please try like this:

<script type="text/javascript">
$(document).ready(function () {
    $.ajaxSetup ({
        cache: false
    });

    var ajax_load = "";

    $( "#<?=$row_items['id_aanbod']?>" ).change(function() {
        $("#res").html(ajax_load).load("update.php", "e="+$("#<?=$row_items['id_aanbod']?>").val() + "&id=" + $("#hrr").attr("id"));
    });
});

Don't forget to check vals. If short open tags is OFF -> then try :

<?php echo $row_items['id_aanbod']?>
