Answer 1

Are you need validation something like this in a Codeigniter callback function?

$this->form_validation->set_rules('email', 'email', 'trim|required|max_length[254]|valid_email|xss_clean|callback_spare_email[' . $this->input->post('email') . ']');

if ($this->form_validation->run() == FALSE)
{
    // failed
    echo 'FAIL';
}
else
{ 
    // success
    echo 'GOOD';
}

function spare_email($str)
{

    // if first_item and second_item are equal
    if(stristr($str, '@mywork.com') !== FALSE)
    {
    // success
    return $str;
    }
    else
    {
    // set error message
    $this->form_validation->set_message('spare_email', 'No match');

    // return fail
    return FALSE;
    }
}
