How to get Affected Rows in CodeIgniter?

1. Get Affected rows or Number of Rows

$query = $this->db->get_where( 'user_albums',
                  array( 'user_id'=>$uid, 'album_name'=>'Untitled') );
$this->db->affected_rows(); 
$query->num_rows();

 

2. Get Result

$res = $this->db->query("select user_id, comments, date from `comments`  where xid = ".$photo_id);

$comment_data = $res->result();
if($res->num_rows() > 0)
{
    foreach($rows as $singlerow)
    {
      //code to fetch data from $singlerow  
    }
}

 

or using result_array

    $comment_data = $res->result_array();

 

3. Get Row Array from get_where

        $query = $this->db->get_where('user_photos',  array('album_id'=>$album_id ) );
        $row = $query->row_array();

 

4. Get Data from Table

        $this->db->select('photo_ids');
        $this->db->from('user_suitcase_items');
        $this->db->where($suitcasedata); 
        $query = $this->db->get();

 

5.  Get Data Using Where Condition.

            $this->db->select('photo_ids');
            $this->db->from('user_suitcase_items');
            $this->db->where($suitcasedata);
