jQuery UI AutoComplete Passing input data

I am sure this has been asked a ton of times, but would appreciate some assistance.

I am trying to setup the jQuery UI, which I can get a static result list with from JSON. But I need to pass my INPUT value onto the PHP script to that it can actually filter the results.

My Code for the Input Field

<input id="search" />

My Code for running my Javascript

$("#search").autocomplete({
   source: 'testData.php',
   dataType: 'json',
   minLength: 2,
   select: function(event, ui) {
            $('#contactId').val(ui.item.id);
            $('#contactName').val(ui.item.value);
   }
});

And testData.php is returning valid JSON data. But I don't know how to pass the variable from the input field to my testData.php so that it actually knows what to search for.

Hope this makes sense.

You don't have to do anything for this. The control automatically passes the value for you. In your php script just use this:

$_GET["term"]

They pass a querystring variable by the name of term. It's in the docs but a little obscure to find.

EDIT: I knew this because I was having the same problem last week trying to find this. Here is the URL to the docs: http://docs.jquery.com/UI/Autocomplete

Also here is the paragraph from the page that explains what to do:

When a String is used, the Autocomplete plugin expects that string to point to a URL resource that will return JSON data. It can be on the same host or on a different one (must provide JSONP). The request parameter "term" gets added to that URL. The data itself can be in the same format as the local data described above.
