点击发布后，更新未显示

Question

我刚刚从this下载了一个墙脚本，我将所有内容都安装到我的数据库中。当我运行我的程序时，当我在文本框中输入内容时它显示正常，并且点击发布它什么都不显示。

当我检查phpMyAdmin时，有一些消息我在文本框中输入，但是点击后它没有显示到墙上，但它显示消息进入数据库？

以下是update.php的代码：

<?php
    require_once "config.php";
    require_once "helper.php";

    $data = array();
    if(isset($_POST)) {
        $type = $_POST['shareType'];
        $data[':message'] = $_POST['message'];
        $data[':type'] = $_POST['shareType'];
        $data[':location'] = ($type == 'location') ? $_POST['location'] : '';
        $data[':lat'] = ($type == 'location') ? $_POST['lat'] : ''; 
        $data[':lng'] = ($type == 'location') ? $_POST['lng'] : ''; 
        $data[':user_id'] = 1; 
        $data[':video_url'] = ($type == 'videos') ? $_POST['videoUrl'] : '';
        $data[':created'] = time();
        $data[':image'] = '';
        //For image upload
        if($type == 'photos' && !empty($_FILES['image'])) {
            $file_exts = array("jpg", "bmp", "jpeg", "gif", "png");
            $upload_exts = end(explode(".", $_FILES["image"]["name"]));
            if ((($_FILES["image"]["type"] == "image/gif")
            || ($_FILES["image"]["type"] == "image/jpeg")
            || ($_FILES["image"]["type"] == "image/png")
            || ($_FILES["image"]["type"] == "image/pjpeg"))
            && ($_FILES["image"]["size"] < 2000000)
            && in_array($upload_exts, $file_exts))
            {
                $data[':image'] = time().'.jpg';
                move_uploaded_file($_FILES['image']['tmp_name'], 'uploads/'.$data[':image']);
            }
        }
        // End
        $stmt = $db->prepare("INSERT INTO post (user_id, created, type, message, location, lat, lng, image, video_url) VALUES (:user_id, :created, :type, :message, :location, :lat, :lng, :image, :video_url)");

            $stmt = $db->prepare('SELECT * FROM post where id=:id');
            $stmt->execute(array(':id' => $id));
            if($stmt->rowCount() > 0) {
