Code:

public function getField($fieldName) {
     $this -> db ->select($fieldName);
     $this -> db -> where("group","config");
     $this -> db -> where("key","config_meta_title");
     $query=$this->db->get('setting');
     return $query->row()->$fieldName; //return the column value of $fieldName
}

$value = $this->document->getField('value');
