嗨,我对codeigniter很新。我有一个代码,几天前工作正常,但当我再次打开它时,它给了我你要求找不到的页面的错误。基本上代码是关于在数据库中添加用户。请帮助我,我需要你的建议。这是我的模型,控制器和视图代码。
模型文件
Userinsert_model.php
<?php
class Userinsert_model extends CI_Model{
function __construct() {
parent::__construct();
}
function form_insert($data){
$this->db->insert('students', $data);
}
public function datafetch(){
$fetch= $this->db->get('students');
return $fetch->result();
}
}
?>
控制器文件
Userinsert_controller.php
<?php
class Userinsert_controller extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('Userinsert_model');
}
function index() {
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
$this->form_validation->set_rules('dname', 'Username', 'required|min_length[5]|max_length[15]');
$this->form_validation->set_rules('demail', 'Email', 'required|valid_email');
$this->form_validation->set_rules('dmobile', 'Mobile No.', 'required|regex_match[/^[0-9]{10}$/]');
$this->form_validation->set_rules('daddress', 'Address', 'required|min_length[10]|max_length[50]');
if ($this->form_validation->run() == FALSE) {
$this->load->view('Userinsert_view');
} else {
$data = array(
'Student_Name' => $this->input->post('dname'),
'Student_Email' => $this->input->post('demail'),
'Student_Mobile' => $this->input->post('dmobile'),
'Student_Address' => $this->input->post('daddress')
);
$this->Userinsert_model->form_insert($data);
$data['message'] = 'Data Inserted Successfully';
$this->load->view('Userinsert_view', $data);
}
}
public function fetch() {
$this->load->model('Userinsert_model');
$data["all_data"]= $this->Userinsert_model->datafetch();
$this->load->helper('form');
$this->load->view('Usershow_view', $data);
}
}
?>

答案 0 :(得分:3)
在config.php
替换
$config['index_page'] = 'index.php';
到
$config['index_page'] = '';
答案 1 :(得分:1)
将class Userinsert_controller extends CI_Controller {
重命名为class Userinsert extends CI_Controller {
,然后通过example.com/index.php/userinsert
答案 2 :(得分:1)
您的application/config/routes.php
必须如此
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

| URI ROUTING
| -------------------------------------------------------------------------
| This file lets you re-map URI requests to specific controller functions.
|
| Typically there is a one-to-one relationship between a URL string
| and its corresponding controller class/method. The segments in a
| URL normally follow this pattern:
|
| example.com/class/method/id/
|
| In some instances, however, you may want to remap this relationship
| so that a different class/function is called than the one
| corresponding to the URL.
|
| Please see the user guide for complete details:
|
| https://codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There are three reserved routes:
|
| $route['default_controller'] = 'welcome';
|
| This route indicates which controller class should be loaded if the
| URI contains no data. In the above example, the "welcome" class
| would be loaded.
|
| $route['404_override'] = 'errors/page_missing';
|
| This route will tell the Router which controller/method to use if those
| provided in the URL cannot be matched to a valid route.
|
| $route['translate_uri_dashes'] = FALSE;
|
| This is not exactly a route, but allows you to automatically route
| controller and method names that contain dashes. '-' isn't a valid
| class or method name character, so it requires translation.
| When you set this option to TRUE, it will replace ALL dashes in the
| controller and method URI segments.
|
| Examples: my-controller/index -> my_controller/index
| my-controller/my-method -> my_controller/my_method
*/
$route['default_controller'] = 'welcome';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
/* CUSTOM ROUTES */
$route['userinsert'] = 'Userinsert';
基本上你需要有以下路线。
$route['userinsert'] = 'Userinsert';
