forgot one line...replace above model, with this

Code:

function recherche($critere)
{
this->db->select('COTE, TITRE, EDITEURS, RESUME, DESCRIPTEURS, MOTSCLES, DIVERS');
$this->db->from ('catalogue_dvd');
this->db->like ('TITRE',$critere);
$this->db->or_like ('EDITEURS',$critere);
$this->db->or_like ('RESUME',$critere);
$this->db->or_like ('DESCRIPTEURS',$critere);
this->db->or_like ('MOTSCLES',$critere);
$this->db->or_like ('DIVERS',$critere);
//the forgotten line
$query = $this->db->get();
$result = $query->result_array();
//if there are a match result, bring first row. Else, Null
return (count($result) > 0 ? $result[0] : NULL);
}
