的PHP代碼如下不起作用。它根本不檢查任何東西。它不顯示最大文件大小錯誤。它所做的是，它接受我嘗試上傳的任何文件並將文件名插入數據庫。它不檢查我爲文件上傳設置的任何限制。任何想法？ TXS文件上傳不起作用

這是不工作的程序員，文件上傳的作品就好了;） – PhearOfRayne
在另一方面：您應該首先替換所有的'mysql_ *'函數。自'PHP 5.5.0'起，它們已被棄用。使用類似[PDO]（http://php.net/manual/en/book.pdo.php）或[庫MySQLi（http://php.net/manual/en/book.mysqli.php） – PhearOfRayne
@ StevenFarley我只是放棄了MySQL的部分從代碼檢查是否正常工作，沒有它，但什麼都沒有改變......你檢查文件上傳的作品？ – Magna
