在 Codeigniter 中按下提交按钮后出现 404 错误

Question

我创建了一个联系表单以将详细信息提交到名为 'ccp' 的数据库，table 名称为 'inquiries' 但是按下提交按钮后，并没有跳转到任何页面，也没有向数据库提交数据。请帮我解决这个错误。

控制器文件 - Contactform.php

<?php

class Contactform extends CI_Controller {

public function __construct(){

        parent::__construct();
        $this->load->helper(array('form','url'));
        $this->load->library(array('session','form_validation'));

        $this->load->database();

}
function index(){
        //set validation rules
        $this->form_validation->set_rules('name', 'Name', 'trim|required|callback_alpha_space_only');
        $this->form_validation->set_rules('email', 'Emaid ID', 'trim|required|valid_email');
        $this->form_validation->set_rules('subject', 'Subject', 'trim|required');
        $this->form_validation->set_rules('message', 'Message', 'trim|required');

        //run validation on post data
        if ($this->form_validation->run() == FALSE)
        {   //validation fails
            $this->load->view('Contact_form_view');
        }
        else
        {
            //insert the contact form data into database
            $data = array(
                'name' => $this->input->post('name'),
                'email' => $this->input->post('email'),
                'subject' => $this->input->post('subject'),
                'message' => $this->input->post('message')
            );

            if ($this->db->insert('inquiries', $data))
            {
                // success
                $this->session->set_flashdata('msg','<div class="alert alert-success text-center">We received your message! Will get back to you shortly!!!</div>');
                redirect('Contactform/index');
            }
            else
            {
                // error
                $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Some Error.  Please try again later!!!</div>');
                redirect('Contactform/index');
            }
        }
}
    //custom callback to accept only alphabets and space input
function alpha_space_only($str){
        if (!preg_match("/^[a-zA-Z ]+$/",$str))
        {
            $this->form_validation->set_message('alpha_space_only', 'The %s field must contain only alphabets and space');
            return FALSE;
        }
        else
        {
            return TRUE;
        }
}
}
?>

除此之外，database.php文件更新如下

    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'ccp',
    'dbdriver' => 'mysqli',

和routes.php如下：

$route['default_controller'] = 'Contactform';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

下面是我遇到的错误

Answer 1

遵循这些方法

为您的项目设置基础 URL。
- 在图像中，我可以看到类似 [::1] 的内容。它的克服是因为每当 base URL 为空时。
加载没有 index.php 的网站。
- 你可以在 form open 中添加 index.php 来避免这种情况。但不推荐。
```
echo form_open("index.php/Contactform/index", $attributes);?>
```
