In codeigniter there is no need to sennd "data" in ajax post method.. here is the example .

   searchThis = 'This text will be search';
    $.ajax({
      type: "POST",
      url: "<?php echo site_url();?>/software/search/"+searchThis,
      dataType: "html",
      success:function(data){
        alert(data);
      },

    });

Note : in url , software is the controller name , search is the function name and searchThis is the variable that i m sending.

Here is the controller.

    public function search(){
    $search = $this->uri->segment(3);
      echo '<p>'.$search.'</p>';
    }

I hope you can get idea for your work .

The question has already been answered but I thought I would also let you know that rather than using the native PHP   POST I reccomend you use the CodeIgniter input class so your controller code would be  function post action            if  this- gt input- gt post  textbox                         message    You can t send empty text             else                message    this- gt input- gt post  textbox              echo  message
