php - 表单验证和记录插入在Codeigniter中不起作用

表单验证和记录插入在codeigniter中不工作
模型

class Mymodel extends CI_Model
{

  function insert($data)
  {
    $this->db->insert("users", $data);
  }
}

控制器

defined('BASEPATH') OR exit('No direct script access allowed');
class Mycontroller extends CI_controller
{

    function index()
    {
        $this->load->view('myfolder/my_page');

    }

    function login()
    {
        $this->load->view('myfolder/login');
    }

    function signup()
    {
        $this->load->view('myfolder/signup');
    }

    function signupmethod()
    {

        $this->load->library('form_validation');

        $this->form_validation->set_rules("firstname","First Name",'requird|alpha');
        $this->form_validation->set_rules("lastname","Last Name",'requird|alpha');
        $this->form_validation->set_rules("email","Email",'requird|alpha');
        $this->form_validation->set_rules("password","Password",'requird|alpha');

        if ($this->form_validation->run())
        {
            $this->load->model("mymodel");

            $data = array(
                "firstname" => $this->input->post("firstname"),
                "lastname" => $this->input->post("lastname"),
                "email" => $this->input->post("email"),
                "password" => $this->input->post("password"),
                "mobile" => $this->input->post("mobile"),
                "curtime" => "NOW()"
            );

            if($this->input->post("Signup"))
            {
                $this->mymodel->insert($data);
                redirect(base_url() . "mycontroller/Inserted");
            }
        }
    }

    public function Inserted()
    {
        $this->index();
    }

}

   ?>

视图（html代码）

<?php include('header.php'); ?>

 <form method="post" action="<?php echo   base_url()?>mycontroller/signupmethod" enctype="multipart/form-data">
  <div class="container">

        <input type="submit" name="submit" value="Signup" class="btn btn-info">

</div>

我已经仔细阅读了每一行，代码运行，但没有错误显示，验证和记录插入不起作用。没有显示错误。
请帮忙。

最佳答案

更改控制器在控制器中获取表单元素时，此代码块始终使用元素名称

if($this->input->post("submit"))
{
      $this->mymodel->insert($data);
      redirect(base_url() . "mycontroller/Inserted");
}
