jQuery UI Autocomplete with CI ??

[quote author="pickupman" date="1272786369"]Since jQuery UI sends the search term as a get parameter you will either enable query strings, or use a js callback function.

@pickupman- this moves me in the right direction, thank you very much.

What is a good method for debugging in this situation? Basically, I don't know if search.php is being called by jQuery or not. How can I tell?

Can I echo data to the display from search.php?. Something tells me no - that this call from jQuery to /search.php is not in the flow of normal data.

Is it correct that search.php does not have any classes or functions? search.php seems to operate like a CI view, except in this case echo sends data to the jQuery request, not to the screen. (correct me if I'm wrong)

Here is my search.php file

Code:

<?php
    $keyword = $this->input->post('term');
    $data['response'] = 'false'; //Set default response
    $this->load->model('inventory/products_model');
    $query = $this->products_model->lookup($keyword); //Search DB
    if($query->num_rows() > 0)
    {
        $data['response'] = 'true'; //Set response
        $data['message'] = array(); //Create array
        foreach($query->$result as $row)
        {
            $data['message'][] = array('label'=> $row->description, 'value'=> $row->product); //Add a row to array
        }
    }
    echo json_encode($data);
?>
