[eluser]fuji2009[/eluser]
Hi i have a problem with callback function :

Code:

function check_infos()
    {
        extract($_POST);
        if (!empty($info))
            {
                $this->db->select('*');
                $this->db->from('loris');
                $this->db->where('email', $info);
                $this->db->where('user1_id', $user_login_id);
                $this->db->where('user2_id', $user_id);
                $query = $this->db->get();
                if($query->num_rows() > 0)
                    {
                        $this->form_validation->set_message('check_infos', 'Already exist');
                        return false;
                    }
                    else
                    {
                        return true;
                    }
            }
    }

Request :

SELECT * FROM (`loris`) WHERE `email` = '[email protected]' AND `user1_id` = '2' AND `user2_id` = '5'


The request is good but, the callback dont work

Can you help me ?

in my controller i have this :

Code:

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

        if ($this->form_validation->run())
        {
.......................................
}

Code:

function check_infos($str)
    {
                $this->db->select('*');
                $this->db->from('loris');
                $this->db->where('email', $str);
                $this->db->where('user1_id', $user_login_id);
                $this->db->where('user2_id', $user_id);
                $query = $this->db->get();
                if($query->num_rows() > 0)
                    {
                        $this->form_validation->set_message('check_infos', '%s already exist');
                        return false;
                    }
                    else
                    {
                        return true;
                    }
    }

Code:

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

if ($this->form_validation->run() == FALSE)
{
    //reload the view
}
else
{
    //success page
}

I do it but don t work, just the form false run and load the view page but, the error message is not here.

For exemple , i try , put nothing in the form and validate and it s load a new page, normally he must say : this input is required ...

What s the problem ?


Thanks you

Have you put in your view echo validation_errors(); ?

Please, post your controller and view code.

        $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',

            $this->profile_model->pre_loran($pre_loran);
            $data['demande'] = 'Mee';
        }
        $data['die']='Already do this action';
        $this->load->view('layout/application', $data);

                    {
                        $this->form_validation->set_message('check_infos', 'Already do');
                        return false;
                    }
                    else
                    {
                        return true;

The call back needs to be in the controller with you other form code or it will not work!

Hum i not understand the callback is in the controller function check_infos

[eluser]Cristian Gilè[/eluser]
Remove some code from the if statement in the pre_loran function as follow:

Code:

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

if ($this->form_validation->run() == FALSE)
{
  $this->load->view('your_view_name'); //reload the view to show errors
}
else
{
  redirect('controller/method'); //redirect to the success page
}

and check if it works.
