jQuery UI Autocomplete with CI ??

@seanloving: yes, change search.php to your search path,[/quote]

when I use source: availableTags everything works fine. But when I use source: "http://localhost/sample.com/search" it does not work.

Code:

<s-cript type="text/javascript" src="&lt;?php echo base_url()."assets/js/jquery-1.4.2.min.js" ?&gt;">[removed]
    <s-cript type="text/javascript" src="&lt;?php echo base_url()."assets/js/jquery.ui.core.js" ?&gt;">[removed]
    <s-cript type="text/javascript" src="&lt;?php echo base_url()."assets/js/jquery.ui.widget.js" ?&gt;">[removed]
    <s-cript type="text/javascript" src="&lt;?php echo base_url()."assets/js/jquery.ui.position.js" ?&gt;">[removed]
    <s-cript type="text/javascript" src="&lt;?php echo base_url()."assets/js/jquery.ui.datepicker.js" ?&gt;">[removed]
    <s-cript type="text/javascript" src="&lt;?php echo base_url()."assets/js/jquery.ui.autocomplete.js" ?&gt;">[removed]
    var availableTags = ["PT-042-GP", "PT-042-TP", "PT-042-JP", "PT-042-RP", "PT-042-WP", "PT-042L-GP", "PT-042L-TP"];
    $(".product_picker").autocomplete({
        //source: availableTags,
        source: "http://localhost/sample.com/search",
        minLength: 1,
        select: function(event, ui) {
            log(ui.item ? ("Selected: " + ui.item.value + " aka " + ui.item.id) : "Nothing selected, input was " + this.value);
        }
    });

The file search.php is located in my application/controllers/ and I am thinking this is in fact correct.

Not sure if I need the jQuery AJAX helper and hook for CI in order to make this work with "remote data".

My ultimate goal is to autocomplete from MySQL database.
