Since CI community is so giving, i shall give back.

Controller/method that gets called

Code:

function search_club_name($city, $state, $name)
    {        
        header('Content-Type: application/json');
        $this->load->model('club_model');    
        $club_names = $this->club_model->getByClubUrl( $city, $state, $name );
        echo count($club_names);
    }

And the AJAX code

Code:

var url = '/ajax/search_club_name/'+  city_string + "/" + state_string + "/" + name_string;
        new Ajax.Request(url, {
              method: 'get',
              onComplete: function(response) {
                  //alert('Complete: ' +  Object.inspect(response.responseText));
                  if(response.responseText == 0) {
                      submitClubForm();
                  } else {
                      var msg = 'Club name"' + name_string + '" has been taken for city of '+ city_string +', '+ state_string + '. Please choose a different name/city combination.'  
                      alert(msg);
                  }
              }
          });
