Codeigniter form_验证不起作用，代码中的所有内容都正常，请帮助我

自动加载：

$autoload['libraries'] = array('database','form_validation');

控制器：

若我从验证中删除了条件，那个么表单可以工作，数据可以移动，当我在验证中应用了条件，那个么表单不工作的数据也不会移动，并且不会显示任何错误

型号：

public function newuser_data($data)
    {
        $this->db->insert('users', $data);
        $query = $this->db->insert_id();
    }

视图：

创建用户！

将此更改为

if ($this->form_validation->run())

到

阅读-

更改您的行

if ($this->form_validation->run())

到

改变你的陈述

来自

if ($this->form_validation->run())

至

if ($this->form_validation->run() == TRUE)

或

如果条件发生变化

if ($this->form_validation->run())

尝试使用此控制器

class Adminlogin extends CI_controller
{
public function new_user()
        {
            $this->form_validation->set_rules('name','name','required');
            $this->form_validation->set_rules('email','email','required|valid_email');
            $this->form_validation->set_rules('password','password','required|min_length[8]|max_length[15]');

            if ($this->form_validation->run()===FALSE)
            {

                echo 'Not done';
            }
            else
            {
                $Name    = $this->input->POST('name');  
                $Email = $this->input->POST('email');
                $Password = $this->input->POST('password');

                $data = array('Name' => $Name, 'Email' => $Email, 'Password' => $Password);
                $this->load->model('login_model');              
                $this->login_model->newuser_data($data);


            $data['message'] = 'Data Inserted Successfully';
        }
    }

index.php是否从URL中删除？然后将

index.php

添加到表单URL中，或使用

.htaccess

$data=array（'Name'=>$Name'，Email'=>$Email'，Password'=>$Password）将其删除$这个->加载->模型（'login_model'）$此->登录\模型->新用户\数据（$data）；数组键的下框有帮助吗？数据正在传递到数据库，它没有任何问题，在应用验证后它不工作。替换-

echo“not done”-带有-
回显验证错误（）-这样您就知道了验证错误。我想您希望
set\u value（..）
的第一个参数都是小写的。嘿@ShabhiNaqvi我想您需要加载表单帮助程序<代码>$this->load->helper（'form'）当您尝试时，它是否会像您定义的那样回显消息“未完成”？如果没有，请像我前面提到的那样，将这个If（$this->form\u validation->run（）==TRUE），并检查您是否配置了“form\u validation”库。就是,$自动加载['libraries']=array（'form_validation'）；
if ($this->form_validation->run())

if ($this->form_validation->run() == TRUE)

if ($this->form_validation->run() != FALSE)

class Adminlogin extends CI_controller

            $this->form_validation->set_rules('name','name','required');
            $this->form_validation->set_rules('email','email','required|valid_email');
            $this->form_validation->set_rules('password','password','required|min_length[8]|max_length[15]');

            if ($this->form_validation->run()!=FALSE)
            {

                $Name    = $this->input->POST('name');  
                $Email = $this->input->POST('email');
