Facebook ウォールのようなサイトに新しい投稿を挿入するページがあります。

サイトに新しい投稿を追加できますが、挿入するとサイトが更新されます。

必要なのは、新しい投稿を挿入すると、ページ全体を更新せずにページに追加されることです。

コントローラーとモデルには大量のデータがあります。今回は扱いたくない。しかし、DB にデータを挿入し、CodeIgniter でページを更新せずに指定されたデータをサイトに表示する方法のサンプルを共有したいと思います。これが役立つと思います。

ここにサンプルビューがあります -

<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>

これがコントローラーです-

/*
* 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;
    }
}

モデルファイル -

/*
* 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();
}

そして今、ここに最も魅力的な Javascript コードがあります - これをビューファイルの最後に追加しただけです

    <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>

そして、これが私の使用したMysqlテーブルです-

  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 ;

だからこれを試してください。仕事とあなたのお役に立てば幸いです。そして、何が起こっているのか教えてください。

これを試して

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

ここにドキュメントがあります

jquery postまたはgetから始めるのに役立つことを願っています
