Question

起初我想对我的“批判性”英语说抱歉。我希望它能够成为这个社区的一部分。：）

我尝试使用ajax / JQuery和PHP / silex编写聊天。

这是我的JS代码：

$(document).ready(function () {
    console.log('data');
    setInterval(function () {

        $.ajax({
            url: './../resources/controller/AjaxCom.php',
            type: 'POST',
            method: 'POST',
            data: formdata,
            success: function () {
                console.log(data);
            },
            error: function () {
                console.log('error');
            }
        });
        return false;
    }, 1000);

    $.('form').submit(
        function () {
        var daten = $('#message').val();

        $.ajax({
            url: './../resources/controller/AjaxCom.php',
            type: 'POST',
            method: 'POST',
            data: {message: daten},
            success: function (daten) {
                console.log(daten);
            },
            error: function () {
                console.log('error at writing');
            }
        });
    });
});

这是PHP文件。这应该传达Ajax，但我得到这个错误：

POST http://localhost/chat/resources/controller/AjaxCom.php 500 
(Internal Server Error)k.cors.a.crossDomain.send @ jquery.js:
4n.extend.ajax @ jquery.js:4(anonymous function) @ ServerCom.js:7

    private $ddConnect;


    /**

    public function getChatOutput()
    {
        return $this->chatOutput;
    }

    /**

     */
    public function getUserOutput()
    {
        return $this->userOutput;
    }

    /**

     */
    public function __construct($datenbankVerbindung)
    {
        $this->ddConnect = $datenbankVerbindung;

    }


    /**
     * @return array
     */
    public function showChatData()
    {
        $posts = $this->ddConnect->fetchAll("SELECT message,writer FROM messages");
        foreach ($posts as $post) {
            $this->chatOutput[$post['message']] = $post['writer'];
        }

        return ($this->getChatOutput());
    }

    /**
     * @return array
     */
    public function showOnUser()
    {
        $users = $this->ddConnect->fetchAll("SELECT name FROM user WHERE status='1'");
        foreach ($users as $user) {
            array_push($this->userOutput, $user['name']);

        }

        return $this->getUserOutput();

    }

    /**
     * @param $message
     * @param $writer
     */


    public function writeChatDateInDb($message,$writer){
        $this->ddConnect->insert(
                'messages',
                array(
                    'message' => $message,
                    'writer' => $writer
                )
            );

    }
}

你帮我找错了吗？非常感谢你的帮助
