Codeigniter Ion Auth register()没有返回错误 - Codeigniter Ion Auth register() not returning errors

我使用Ion Auth进行身份验证，并且难以返回验证错误。login();函数按预期返回它们，当运行register();时，我被正确地重定向，但是没有返回错误。

表单验证:

$this->load->library('form_validation', array(), 'register_form');
$this->register_form->set_rules('first_name', $this->lang->line('create_user_validation_fname_label'), 'required|xss_clean');
$this->register_form->set_rules('last_name', $this->lang->line('create_user_validation_lname_label'), 'required|xss_clean');
$this->register_form->set_rules('email', $this->lang->line('create_user_validation_email_label'), 'required|valid_email');
$this->register_form->set_rules('phone', $this->lang->line('create_user_validation_phone_label'), 'required|xss_clean');
$this->register_form->set_rules('company', $this->lang->line('create_user_validation_company_label'), 'required|xss_clean');
$this->register_form->set_rules('password', $this->lang->line('create_user_validation_password_label'), 'required|min_length[' . $this->config->item('min_password_length', 'ion_auth') . ']|max_length[' . $this->config->item('max_password_length', 'ion_auth') . ']|matches[password_confirm]');
$this->register_form->set_rules('password_confirm', $this->lang->line('create_user_validation_password_confirm_label'), 'required');

if($this->register_form->run() == true){
    $username = strtolower($this->input->post('first_name')) . ' ' . strtolower($this->input->post('last_name'));
    $email    = $this->input->post('email');
    $password = $this->input->post('password');
    $additional_data = array(
        'first_name' => $this->input->post('first_name'),
        'last_name'  => $this->input->post('last_name'),
        'company'    => $this->input->post('company'),
        'phone'      => $this->input->post('phone'),
    );
    if($this->ion_auth->register($username, $password, $email, $additional_data)){
        $this->ion_auth->set_message_delimiters('','');
        $this->session->set_flashdata('register_message', $this->ion_auth->messages());
        redirect('home/index', 'refresh');
    }else{
        $this->ion_auth->set_error_delimiters('','');
        $this->session->set_flashdata('register_error', $this->ion_auth->errors());
        redirect('home/index', 'refresh');
    }
}

这就是我如何将flash数据传递给我的视图:

$this->data['register_message'] = $this->session->flashdata('register_message');
$this->data['register_error'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('register_error');

在我看来，当与$register_error相呼应时，我没有得到任何东西，当运行register();后用print_r($this->session->all_userdata());打印会话对象时，user_data数组为空。我正在运行register();与空字段，所以应该有错误。有什么建议吗?

CodeIgniter "flashdata"，将只适用于下一个服务器请求，然后自动清除。

这就是为什么你不能在会话数据中找到它。你可以通过附加的keep_flashdata请求来保存flashdata变量。

$this->session->keep_flashdata('item');

这一行有一个右括号错误。

$this->data['register_error'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('register_error');

改为

$this->data['register_error'] = (validation_errors() ? validation_errors() : $this->session->flashdata('register_error'));
