jQuery Pass an attribute from JQuery to PHP (on event)?

[branko7171]

Hello, first I want to point that I'm using jQWidgets.
I want to pass an attribute from jquery to a PHP file. Now, I've tried using $.post.
Like this:

$('#problemiTree').bind('select', function (event) {
                    var item3 = $('#problemiTree').jqxTree('getSelectedItem');
                    if (item3 && item3.parentId!=0)
                        dataAdapter4.dataBind();
                    $.post( 
                    "problemiOblastData.php",
                    { selectedItem: item3.label }
                    

                );

In the PHP file I test with:

if (isset($_GET['selectedItem:']))
    echo 'no';
else
    echo 'yes';

And it always gives "no".

Please help,
thank you.

well no one else answered so I took a look. Looks to me like $('#problemiTree').jqxTree('getSelectedItem'); returns an array, and I'm pretty sure .label only works on form elements, so maybeyou jsut need to remove the .label?

I've tried that and I have modified the code in php like so (it was not correct):

if (isset($_POST['selectedItem']))
    echo 'yes';
else
    echo 'no';

My problem remains ('no' again), but thanks anyway.

EDIT: Maybe I'm not testing correctly. I use a direct link to the php file to check echo.
I've tried using $.ajax, but the result is the same. Is there maybe another way for me to pass data to php?

SOLVED
I've figured out what was the problem. I passed item.label (or item), where I should have passed item.id. mySQL query in the php file requires that id, and it won't work with label etc...
