callback from model

[eluser]smith[/eluser]
so, your example from above would be:

inside forms model:

Code:

$rules['password']   = "required|check_password"; //callback

inside callback library:

Code:

function check_password($password)
{
    if (password false)
    {
        $this->validation->set_message('check_password', $this->CI->config->item('reg_form_password_check'));
        return false;    
    }
    else
    {
        return true;
    }
}

inside callback library you can see entire $this, except you have to call it like:

Code:

$this->CI->data['something']
or
$this->CI->validation->something
or
$this->CI->input->post('something') ...
