无法使用codeigniter将数据写入数据库

Question

我有一个控制器、模型和视图文件。我正在尝试使用视图文件上的表单将数据写入数据库。我正在尝试使用 Codeigniter 验证库和由定义的一些方法来验证发布数据。此验证在 Controller 中完成。然后我试图将数据数组传递给模型。在模型中，我试图读取数据数组并构建查询以在数据库中插入数据。

问题是没有数据写入数据库。 我在浏览器中看不到任何可见的错误。我已经坚持了一段时间了。任何帮助表示赞赏。提前致谢。

控制器

function add_customer() {

    $this->load->model('Customer_Model');
    $data['title'] = "Add New Customer";


    $this->load->view('templates/header' , $data);
    $this->load->view('dashboard/add_customer' , $data);
    $this->load->view('templates/footer' , $data);

    if($this->input->post())
    {

        $this->form_validation->set_rules('name', 'Name', 'trim|required');
        $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|customer_email_exists');
        $this->form_validation->set_rules('mobile', 'Mobile', 'trim|required|customer_mobile_exists');
        $this->form_validation->set_rules('address', 'Address', 'trim|required');

        if ($this->form_validation->run()){
              $customer_data = array(
                        'name' => $this->validation->name,
                        'email' => $this->validation->email,
                        'mobile' => $this->validation->mobile,
                        'address' => $this->validation->address
                        );
                $this->Customer_Model->add_customer($customer_data);
            }else{

            }
    }
}
public function customer_email_exists($email) {
    $this->load->model('Customer_Model');   
    if(!$this->Customer_Model->email_exists($email)){
            return true;
        }else{
            $this->form_validation->set_message('email_exists', 'Email already registered, try another one.');
            return false;
        }
    }
public function customer_mobile_exists($mobile) {
    $this->load->model('Customer_Model');   
    if(!$this->Customer_Model->mobile_exists($mobile)){
            return true;
        }else{
            $this->form_validation->set_message('email_exists', 'Email already registered, try another one.');
            return false;
        }
    }

}

型号

class Customer_Model extends CI_Model{
function add_customer($customer_data)
{

    $data = array(
        'id'=>'',
        'name'=>$customer_data["name"],
        'email'=>$customer_data["email"],
        'mobile'=>$customer_data["mobile"],
        'address'=>$customer_data["address"]
    );
    $this->db->insert('customer',$data);
    $this->db->query($query);
}
public function email_exists($email) {
        $this->db->where("email = '$email' AND email != ''");
        $query = $this->db->get('customer');
        if ($query->num_rows() > 0){
            return true;
        }else{
            return false;
        }
    }
    public function mobile_exists($mobile) {
        $this->db->where('mobile',$mobile);
        $query = $this->db->get('customer');
        if ($query->num_rows() > 0){
            return true;
        }else{
            return false;
        }
    }}

嗯！我认为在此代码部分中，您应该从输入中获取发布数据，而不是从验证中获取

if ($this->form_validation->run()){
  $customer_data = array(
      'name' => $this->input->post('name'),
      'email' => $this->input->post('email'),
      'mobile' => $this->input->post('mobile'),
      'address' => $this->input->post('address'),
  );
  $this->Customer_Model->add_customer($customer_data);
}else{

}
