JQUERY 脚本

function open_form()
{
    $('#result_wifi').attr({style : 'display:none'});
    $('#form_wifi').removeAttr('style');
}

function registration()
{
$('#result_post_wifi').html('<div class="alert alert-info">Sending Data  ...</div>');
    $.ajax({
                dataType     : "json",
        type     : "POST",
        url      : "wifi/wifi_sign_up",
        data     : "username=" + $('#username').val() + 
                   "&password=" + $('#password').val() + 
                   "&password2=" + $('#password2').val() + 
                   "&name=" + $('#name').val() + 
               "&email=" + $('#email').val() + 
        success  : function(res)
                            {
                                $('#result_post_wifi').html(res.message);
                                if(res.status == '200')
                                {
                                        $('#username').val('');
                                        $('#password').val('');

                                        $('#email').val('');                                 
                                        $('#form_registrasi_field').attr({style : 'display:none'});
                                }
            },
        error   : function(){ $('#result_post_wifi').html('<div class="alert alert-warning">Fail to send registration form.</div>'); }, 
                timeout: 50000          
    });     
    return false;
}

控制器

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Wifi extends MX_Controller {

    public function __construct()
    {
        parent::__construct();
//      $this->load->model('wifi_model');
    }                                  



        public function sign_up()

    {
                $username          = $this->input->post('username');
                $password          = $this->input->post('password');
                $password2          = $this->input->post('password2');      
                $name               = $this->input->post('name');
                $email             = $this->input->post('email');

               $this->wifi_model->add_user();
               header("Content-type: application/json");
               echo "{\"data\":" .json_encode($data). "}";

模型

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Wifi_model extends MX_Model {

    public function __construct()
    {
        parent::__construct();
    }

 public function add_user($data)
    {
        $data=array(
            'username'=>$this->input->post('username'),
            'password'=>md5($this->input->post('password')),
            'password2'=>md5($this->input->post('password2')),
            'name'=>$this->input->post('name'),
            'email'=>$this->input->post('email'),

            );

        $this->db->insert('wifi_regs', $data);  

上面的代码还是不想插入到mysql数据库中。

我一直在尝试其他方法，但它仍然不起作用

查看

var data = $('#form-registrasi-field').serialize();

$.ajax({
                dataType     : "json",
        type     : "POST",
        url      : "wifi/sign_up",
        data     : data,
        success  : function(res)
                            {
                                $('#result_post_wifi').html(res.message);
                                if(res.status == '200')
                                {
                                        $('#form-registrasi-field')
                                           .find('input').val('');
                                        $('#form-registrasi-field').hide();                                    }
            },
        error   : function(){ $('#result_post_wifi').html('<div class="alert alert-warning">Fail to send registration form.</div>'); }, 
                timeout: 50000          
    });     

控制器

public function sign_up(){
       $data['status'] = 200;
       $data['message'] = 'OK';
       if (!$this->wifi_model->add_user()){
           $this->output->set_status_header('500');
           $data['status'] = 500;
           $data['message'] = 'KO :( ';
       }
       //$data['post'] = $this->input->post();
       echo json_encode($data);
}

型号

$this->db->insert('wifi_regs', $data);  
if ($this->db->affected_rows() == 1)
   return true;

return false;
