我正在尝试使用CodeIgniter的recaptcha。我遵循了一些在线说明，最后我只完成了一步，只是将recaptcha传递给视图，但我无法验证用户输入。
这是我的控制器：
function download_application()
{
//load the libraries
$this->load->library('form_validation');
$this->load->library('recaptcha');
$this->lang->load('recaptcha');
//common data
$data['title'] = $_POST['application_name'];
$data['header'] = $_POST['application_name'];
$data['sub_header'] = 'تحميل استمارة قبول المشروع';
$data['title'] = $_POST['application_name'];
$data['recaptcha'] = $this->recaptcha->get_html();
//form validation
$this->form_validation->set_error_delimiters('<span class="notification">', '</span>');
$this->form_validation->set_message('required', 'هذا الحقل مطلوب ولا يمكن تجاهله');
$this->form_validation->set_rules('name', 'لابد من ادخال اسمك بالكامل', 'required');
$this->form_validation->set_rules('email', 'لابد من ادخال بريدك الالكترونى', 'required|email');
$this->form_validation->set_rules('country', 'لابد من ادخال بلدك', 'required');
$this->form_validation->set_rules('phone', 'لابد من ادخال رقم تليفونك', 'required');
//form submitted
if($this->input->post('recaptchasubmit')){
if($this->form_validation->run() == FALSE)
{
$this->load->view('header', $data);
$this->load->view('download', $data);
$this->load->view('footer', $data);
}
else
{
$this->load->view('header', $data);
$this->load->view('download', $data);
$this->load->view('footer', $data);
}
}
else{
$this->load->view('header', $data);
$this->load->view('download', $data);
$this->load->view('footer', $data);
}
}
这是我的观点
