我从其他帖子中尝试了很多解决方案，但似乎什么都不起作用
这部分是我遇到麻烦的地方，但我不知道如何让它工作
$this->load->library('form_validation');
$this->load->library('form');
控制器
<?php
namespace AppControllers;
class Home extends BaseController
{
public function __contruct()
{
parent::__construct();// you have missed this line.
}
public function index()
{
helper (['form']);
return view('inicio');
}
public function descarga()
{
return view('filesnames');
}
public function conta()
{
$this->load->library('form_validation');
$this->load->library('form');
return view('contact/index');
}
public function pregu()
{
return view('preguntas');
}
public function dud(){
return view('duda');
}
public function contact()
{
$autoload['libraries'] = array('session','Email','form','form_validation');
$autoload['helper']=array('form', 'url');
//Set form validation
$this->form_validation->set_rules('name', 'Name', 'trim|required|min_length[3]|max_length[20]');
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|min_length[0]|max_length[60]');
$this->form_validation->set_rules('message', 'Message', 'trim|required|min_length[5]|max_length[200]');
//Run form validation
if ($this->form_validation->run() === FALSE)
{
$this->load->view('contacto');
} else {
//Get the form data
$name = $this->input->post('name');
$from_email = $this->input->post('email');
$subject = $this->input->post('subject');
$message = $this->input->post('message');

} else {

$this->load->view('contacto');
}
}
}
}

Codeigniter 3.x没有名为"形式"；。因此，除非您创建了这样一个库，否则对它的调用将返回一个错误。
另一方面有一个辅助函数"；形式"；，你可以用打电话
$this->load->helper('form');
请遵循文件，这是一个很大的帮助：
表单验证

编辑，评论后：另一方面，这可能是由打字错误引起的：
public function __contruct()
{
parent::__construct();// you have missed this line.
}
应该肯定是public function __construct()
