将图像文件数组插入MySql数据库

我正在创建一个包含多达20个图像文件的库存表单。当上传图像到服务器时，我需要更改名称，并将它们插入数据库，以便在网站转盘上工作。上传时名称更改正常。我似乎遇到的问题是，这些图像在数据库中的名称相同，但在上传时是唯一的。我可能过于关注显而易见的东西了。有什么帮助吗？有什么想法吗？？

这就是我现在的位置；

<?php
if(Input::exists()) {
    if(Token::check(Input::get('token'))) {
        try {
            if(!empty($_FILES['image']['name'][0])) {
                $files = $_FILES['image'];
                $uploaded = array();
                $failed = array();
                $allowed = array('gif', 'png', 'jpg', 'jpeg');
                foreach($files['name'] as $position => $file_name) {
                    $file_tmp = $files['tmp_name'][$position];
                    $file_size = $files['size'][$position];
                    $file_error = $files['error'][$position];
                    $file_ext = explode('.', $file_name);
                    $file_ext = strtolower(end($file_ext));
                    if(in_array($file_ext, $allowed)) {
                        if($file_error === 0) {
                            if($file_size <= 2097152) {// 2MB
                                $file_name_new = uniqid('', true) . '.' . $file_ext;
                                $file_destination = 'assets/uploads/' . $file_name_new;

                                if(move_uploaded_file($file_tmp, $file_destination)) {
                                    $uploaded[$position] = $file_destination;
                                } else {
                                    $failed[$position] = "[{$file_name}] failed to upload";
                                }
                            } else {
                                $failed[$position] = "[{$file_name}] is too large";
                            }
                        } else {
                            $failed[$position] = "[{$file_name}] errored with code [{$file_error}]";
                        }
                    } else {
                        $failed[$position] = "[{$file_name}] file extension '{$file_ext}' is not allowed";
                    }
                }
            }
            $insert = DB::getInstance()->insert('stock', array(
                    'image'         =>  $file_name_new,
                    'image_1'       =>  $file_name_new,
                    'image_2'       =>  $file_name_new,
                    'image_3'       =>  $file_name_new,
                    'image_4'       =>  $file_name_new,
                    'image_5'       =>  $file_name_new,
                    'image_6'       =>  $file_name_new,
                    'image_7'       =>  $file_name_new,
                    'image_8'       =>  $file_name_new,
                    'image_9'       =>  $file_name_new,
                    'image_10'      =>  $file_name_new,
                    'image_11'      =>  $file_name_new,
                    'image_12'      =>  $file_name_new,
                    'image_13'      =>  $file_name_new,
                    'image_14'      =>  $file_name_new,
                    'image_15'      =>  $file_name_new,
                    'image_16'      =>  $file_name_new,
                    'image_17'      =>  $file_name_new,
                    'image_18'      =>  $file_name_new,
                    'image_19'      =>  $file_name_new
            ));
        } catch(Exception $e) {
            die($e->getMessage());
        }
    }
}
?>

以及Form模型；

<div class="row">
    <div class="form-group">
        <div class="col-md-6">

    </div>
</div>
<br>
<button class="btn btn-primary disabled" type="submit">FORM SUBMIT</button>
<input type="hidden" name="token" value="<?php echo Token::generate(); ?>">

有人能帮我吗，在这里挠头：-（
