Filesize错误信息

不知是否有人能帮我一下。

我正在尝试将'filesize'错误信息合并到脚本中，如下所示，用于将BLOB文件上传到mySQL服务器。

if (!mysql_connect($db_host, $db_user, $db_pwd))
    die("Can't connect to database");
if (!mysql_select_db($database))

// $_GET, $_POST, etc... variables 
// completly safe in SQL queries 
function sql_safe($s)

        $s = stripslashes($s); 
    return mysql_real_escape_string($s); 
}

if ($_SERVER['REQUEST_METHOD'] == 'POST')

    if (!isset($_POST["action"]))

        $title = trim(sql_safe($_POST['title']));

        else if ($_POST["action"] == "delete") 
        { 
            $imageid = intval($_POST['del']); 
            mysql_query("DELETE FROM {$table} WHERE imageid=$imageid"); 
            $msg = 'Image deleted'; 
        } 
    } 
} 
?> 

通过我在这个网站上收到的一些指导，我已经能够想出检查文件大小的方法，从这一行开始:

if($_FILES["fileupload"]["size"]/1024000 >= 10) 

但是我不能使错误信息工作。

如果文件大小超过1MB，则需要激活特定的消息。当我尝试上传大于此值的文件时，文件被正确拒绝，但我收到不正确的错误消息，' error: unknown file format'。

我已经尝试了所有的方法来尝试让这个工作，但我只是得到同样不正确的错误信息。

如果有人能看一下这个，告诉我哪里错了，我将非常感激。
