表单验证和记录插入在代码点火器中不起作用

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');
$this->form_validation->set_rules("mobile","Mobile",'requird|alpha');
if ($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">
<div class="row">

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

Answer 1

在控制器中获取表单元素时更改控制器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");
}

Answer 2

正确拼写

$this->form_validation->set_rules("firstname","First Name",'required|alpha');

Answer 3

您的set_rules语句不正确。使用required而不是requird否则set_rules将失败。

当您不确定form_validation失败的原因时，请尝试获取以下错误：

If($this->form_validation->run() == false)
{
echo validation_error();
}
