我有一个页面可以在 facebook wall 之类的网站中插入新帖子。

我可以在我的网站中添加新帖子，但是当我插入它时，网站会刷新。

我需要的是，当我插入一个新帖子时，它被添加到页面而不刷新整个页面。

我的控制器：-

<?php



if (!defined('BASEPATH'))

    exit('No direct script access allowed');



class MyAccount extends MY_Controller {



    var $data;
    var $errors;




    function __construct() {



        parent::__construct();

        $this->template->title('Home');



        if(!isset($_SESSION['user_id']) || empty($_SESSION['user_id'])){
            redirect('./home');
        }
        else {$this->template->set_layout('myaccount');}




    }





    public function index() {

        if(!isset($_SESSION['user_id']) || empty($_SESSION['user_id'])){
            redirect('./home');
        }

您的控制器和模型中有大量数据。这次我不想处理。但我想与您分享一个如何在数据库中插入数据然后在您的站点中显示给定数据而不在 CodeIgniter 中刷新页面的示例。我认为这会有所帮助。

这是示例视图 -

<form action="" method="post" accept-charset="utf-8">

        <table align="center">

            <tr>
                <td>Message :</td>
                <td>
                    <textarea name="message" id="message" placeholder="Write here the message"></textarea>
                </td>
            </tr>

            <tr>
                <td>&nbsp;</td>
                <td id="result"> </td>
            </tr>

            <tr>
                <td>&nbsp;</td>
                <td>
                    <button type="button" id="submit">Submit</button>
                </td>
            </tr>

        </table>

    </form>

这是控制器 -

/*
* this is just to load you view page call test.php from your view folder (Which is my given view file)
*/ 

public function test() {
    $this->load->view('test');
}

 /*
 * this is for insert data via Ajax and get the data
 */

public function insertByajax() {

    $data['message'] = $this->input->post('message');

    $insert = $this->YOURMODEL_NAME->insertDataToDB($data);

    if ($insert) {
        //get the last entry data
        $content = $this->YOURMODEL_NAME->getLastEnrtyData();
        echo $content->message;
    }
}

模型文件 -

/*
* Insert data to the content table
*/
public function insertDataToDB($data) {
    return $this->db->insert('content', $data);
}


/*
* Get the Inserted data from content table
*/
public function getLastEnrtyData() {
    $this->db->from('content');
    $last_id = $this->db->insert_id();
    $this->db->where('id', $last_id);

    return $this->db->get()->row();
}

现在这是最迷人的 Javascript 代码 - 刚刚在视图文件的末尾添加了这个

    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

    <script type="text/javascript">
        $(function() {

            $('#submit').click(function() {

                //get input data as a array
                var post_data = {
                    'message': $("#message").val(),
                    '<?php echo $this->security->get_csrf_token_name(); ?>': '<?php echo $this->security->get_csrf_hash(); ?>'
                };

                $.ajax({
                    type: "POST",
                    url: "<?php echo base_url(); ?>YOUR_CONTROLLER/insertByajax",
                    data: post_data,
                    success: function(message) {
                        // return success message to the id='result' position
                        $("#result").html(message);
                    }
                });

            });

        });
    </script>

这是我用过的 Mysql 表 -

  CREATE TABLE IF NOT EXISTS `content` (`id` int(11) NOT NULL AUTO_INCREMENT, `message` text NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

所以试试这个。希望对您有所帮助和帮助。让我知道发生了什么事。

尝试这个

$.ajax({
   type: "POST",
   url: url,
   data: data,
   success: function(res){
      // do stuff
   },
});

这是文档

我希望从 jquery post 或 get 开始会有所帮助
