Stock with sending data with jQuery to PHP file

Question

I'm trying to send data via POST to PHP file.. $.get() - works fine, hovewer I couldn't tell the same about $.post() or $.ajax() with method post.. Here my code I wrote:

$('[name="update"]').click(function(){
    tr = $(this).parents('tr');
    u = [];
    u["username"] = tr.find('[name="u[username]"]').val();
    u["display_name"] = tr.find('[name="u[display_name]"]').val();
    u["type"] = tr.find('[name="u[type]"]').val();

    $.ajax({
        type: "POST",
        url: "../ajax-queries/update-user.php",
        data: {update:u},
        cache: false,
        success:  function(data){
           alert(data);
        }
     });

});

And PHP file looks like:

<?php 
     print_r($_POST);
?>

Response I get:

Array(
)

Using latest jQuery lib... no ideas why not working.. any solutions you can offer? Is that could be posible because of port:2014? in case i tried and in :80 (same results)..

Are you sure that url: "../ajax-queries/update-user.php", is correct? I remind you that you must take into consideration the path where the PAGE where you add this <script> jquery file is and NOT where your jquery folder is when contructing the url parametre. — Stefanos Vakirtzis

Yeah, I had good dir, in case I wouldn't get an empty Array() response :) however your offer might will help to others someday. — JDSolutions

Because you aren't setting anything.
Try changing u to {}, like: u = {};

Worked after I tried data:{update:u["..."]}, anyways.. is there a way to send an array?

Andrey Over a year ago

are you sure ? try clear browser cache ... maybe the changes at the code aren't take effect (because it's cached.)

Array with key index is not an array, it's an object, try alert(typeof u). sending an array with key index will fail in IE8.
