php - Multiple (unwanted) executions when passing parameter to controller -

i'm using codeigniter,

i have controller called 'property' action called 'details'

the function defining 'details' action takes 2 parameters:

so have url : example.com/property/details/23/appartment-for-rent

the first parameter id of record on db, 2nd parameter seo purposes

the details action increments views of record on db

problem :
when use http://example.com/property/details/23 works fine
when use seo link http://example.com/property/details/23/appartment-for-rent the script executes several times causes views count inaccurate. here controller/action function:

public function details($propertyid){         $this->load->model('model_property');         $pagedata['property'] = $this->model_property->getbyid($propertyid);          if($pagedata['property']!=null){             $this->model_property->incrementviewbyid($pagedata['property']->id);             $this->load->view('_common/header');             $this->load->view('_common/navigation');             $this->load->view('property/details',$pagedata);             $this->load->view('_common/footer');          }else{             redirect(base_url().'error');         }     } 

here function increments views on model:

public function incrementviewbyid($id){         $this->db->where('id', $id);         $this->db->set('views', 'views+1', false);          $this->db->update('property');     }
