在 blueimp/jquery-file-upload 上向 mysql 插入添加更多自定义变量

我目前正在通过 mysql 在 blueimp/jquery-file-upload 脚本内插入标题和描述。我用了this但是，我需要添加另一个变量。该变量是当前登录用户的session ID$_SESSION["userid"]，我想将其插入到我添加的名为uid。通常，在插入中添加另一列很简单，但是这个脚本非常敏感，每当我弄乱它时，即使是最轻微的一点，我都会得到“SyntaxError: Unexpected token <“。 任何帮助将不胜感激。

$upload_handler = new CustomUploadHandler($options);

假设您想要更改 INSERT 查询（您发布的代码中只有一个 INSERT 查询），这就是您需要更改的内容：

if (empty($file->error)) {
    $sql = 'INSERT INTO `'.$this->options['db_table']
            .'` (`name`, `size`, `type`, `title`, `description`, `uid`)'
            .' VALUES (?, ?, ?, ?, ?, ?)';
    $query = $this->db->prepare($sql);
    $query->bind_param(
            'sisss',
            $file->name,
            $file->size,
            $file->type,
            $file->title,
            $file->description,
            $_SESSION['userid']
        );
    $query->execute();
    $file->id = $this->db->insert_id;
}
