Answer 1

The query in your model is returning either string or object data, instead of an array. The 'foreach' loop function accepts an array as its first argument.

Answer 2

I think this code modular:

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

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

    return $this->db->query($query)->result_array();
}

Answer 3

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 $row) {
        echo '<tr>';
        echo '<td>'.$row->bcode.'</td>';
        echo '<td>'.$row->bname.'</td>';
        echo '<td>'.$row->btel.'</td>';
        echo '<td>'.$row->badd.'</td>';
        echo '</tr>';
    }
}
