Hi in my script I want to add pagination and I edit model to

Code:

function getAll($limit = 0, $offset = 0) {
        //$q = $this->db->query('SELECT certs.ser_cislo, certs.pocatek, certs.konec, certs.id_user, users.prijmeni as jmeno FROM certs,users
        //            WHERE certs.id_user = users.id');
        $this->db->select('certs.*');
        $this->db->select('users.prijmeni as jmeno');
        $this->db->from('certs');
        $this->db->join('users', 'certs.id_user=users.id');
        $q = $this->db->get($limit, $offset);
        if ($q->num_rows() > 0) {
            foreach ($q->result() as $row) {
                $data[] = $row;
            }
            return $data;
        }

but after edit i have the error:

A Database Error Occurred

$q = $this->db->select('certs.ser_cislo, certs.pocatek, certs.konec, certs.id_user, users.prijmeni as jmeno')
->join('users', 'certs.id_user=users.id')
->limit($limit, $offset)
->get('certs');

You're missing the first parameter from get() which should be the table name. AFAIK if you want to use the limit and offset parameters, you'll need to either include the table name with the get() call or use the limit() function.

Code:

$this->db->select('c.*, u.prijmeni jmeno');
$this->db->join('users u', 'c.id_user = u.id');

$query    = $this->db->get('certs c', $limit, $offset);

// OR (longer version)

$this->db->select('c.*, u.prijmeni jmeno');
$this->db->from('certs c');
$this->db->join('users u', 'c.id_user = u.id');
$this->db->limit($limit, $offset);

$query    = $this->db->get();

Code:

$query = $this->db->select('certs.*, users.prijmeni as jmeno')
      ->join('users', 'certs.id_user=users.id')
      ->get('certs',$limit,$offset);
