Hi all!
I just finish read this articles
http://www.weblee.co.uk/2009/06/10/simple-jquery-ajax-with-codeigniter-part-4/

and I still can pass variables from form to my controller using ajax :/

here is my controller:

Code:
public function check() {

  // secure

  if (!$this->input->is_ajax_request()) redirect(base_url());

  // vars

  $callback = ''; // here i want a value of input in my form on view page

  // valid

  // output

  echo $callback;

 }

here view:

Code:
&lt;form action="&lt;?php echo base_url(); ?&gt;upload" method="post" enctype="multipart/form-data" id="upload-form"&gt;

      <div class="show_upload" id="upload-local">

        &lt;input type="file" name="file_local" value="" /&gt;

      </div>

      <div class="hide_upload" id="upload-remote">

          &lt;input type="text" name="file_remote" value="" /&gt;

      </div>

      <a id="upload-button"><span>Upload</span></a>

    &lt;/form&gt;

and here my ajax code:

Code:
var upload_url = '&lt;?php echo base_url(); ?&gt;upload/check';

var upload_form = "#upload-form";

  $.ajax({

   url: upload_url,

   type: 'post',

   data: $(upload_form),

   dataType: 'html',

   success: function(callback) {

    if (callback !== '') {

     html = '<div><a class="box error corners"><span class="close">&nbsp;</span>' + callback + '</a></div>';

     $(info_box).append(html);

     $(info_box).slideDown(slide_delay);

    }

    else {

     $(upload_form).submit();

     return false;

    }

   }

  });
