我的表格有3个单选按钮用于我的注册表单 - 用户可以选择3个用户角色中的一个。如果您选择第一个单选按钮，您会看到以下下拉菜单：区域，学校，教师，班级和班级，对于单选按钮2 - 您会看到第一个下拉菜单，但没有老师。如果您选择第3个单选按钮，则会看到所有教师的复选框。 我根据用户选择显示和隐藏下拉列表。 如何进行表单验证 - 如果选择第一个单选按钮，则仅显示用于该单选按钮的表单验证规则。等三个单选按钮。我的控制器是：
public function register()
{
$this->form_validation->set_rules('first_name', 'First name', 'trim|required');
$this->form_validation->set_rules('last_name', 'Last name', 'trim|required');
$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[6]|max_length[12]|is_unique[users.username]');
$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[6]');
$this->form_validation->set_rules('password2', 'Confirm password', 'trim|required|matches[password]');
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|is_unique[users.email]');
$this->form_validation->set_rules('location', 'Location', 'trim|required');

$this->form_validation->set_rules('teacher[]', 'Teacher', 'required');
//$this->form_validation->set_rules('all_teachers_show', 'All teachers', 'required');
if ($this->form_validation->run()==FALSE)
{
$this->signup();
}
else
{
if( $this->user_model->register())
{
$data['dynamic_view'] = 'success_reg';
$this->load->view('templates/main',$data);

检查发布的数据 -
if ($this->input->post('radio_button') == 1){
$this->form_validation->set_rules('min_length', 'Minimum Length', 'trim|required|max_length[3]|integer');
//add more validation
}
if ($this->input->post('radio_button') == 2){
