                </tr>
                <tr><td>&lt;?php echo form_error('info','<div class="error">','</div>');?&gt;</td></tr>
                <tr>
                    <td>&lt;?php echo form_submit('valid_loran','Valider');?&gt;</td>
                </tr>
    &lt;?php echo form_close();?&gt;
            </table>
</div>

Code:

function pre_loran($user_id){
        $data['page'] = 'person_error';
        $data['title'] = 'Erreur';
        
        $data['username'] = $this->session->userdata('username');
        
        $data['user_id'] = '';
        $data['user2_id'] = '';
        
        $this->load->model('profile_model');

        $this->form_validation->set_rules('info','Info','callback_check_infos|trim|required|valid_email|xss_clean');

        if ($this->form_validation->run())
        {
            $data['page'] = 'person_success';
            $data['title'] = 'pre loran';
            extract($_POST);
            
            $username = $this->profile_model->get_username_by_id($user_login_id);
            $username_profil=$this->profile_model->get_username_by_id($user_id);
            $email_profil=$this->profile_model->get_email($user_id);
            $this->email->from('[email protected]', 'Presn');
            $this->email->to($email_profil);
            $this->email->subject('pre_loran');
            $this->email->message(''.$username.' <img src="'.$photos.'" />
                                    <a href="#">Click</a>
                                ');
            $this->email->send();
            
            $pre_loran = array(
                'user1_id' => $user_login_id,
                'user2_id' => $user_id,
                'user3_id' => '',
                'email' => $info,
                'type' => 'present',
                'valide' => 0,
                'created_at' => date('Y-m-d h:i:s',now())
            );
            $this->profile_model->pre_loran($pre_loran);
            $data['demande'] = 'Mee';
        }
        $data['die']='Already do this action';
        $this->load->view('layout/application', $data);    
    }

function check_infos($str)
    {

                $this->db->where('user2_id', $user_id);
                $query = $this->db->get();
                if($query->num_rows() > 0)
                    {
                        $this->form_validation->set_message('check_infos', 'Already do');
                        return false;
