you need to do a check before starting to iterate for the data, like: model code:

public function getAll() {
    $results = array();
    $this->db->select('bcode, bname, btel, badd');
    $this->db->from('branches');

    $query = $this->db->get();

    if($query->num_rows() > 0) {
        $results = $query->result();
    }
    return $results;
}

view code:

if( !empty($results) ) {
    foreach($results as $row) {
        echo '';
        echo ''.$row->bcode.'';
        echo ''.$row->bname.'';
        echo ''.$row->btel.'';
        echo ''.$row->badd.'';
        echo '';
    }
}
