內部服務器錯誤與SQL代碼

我想插入值到MySQL數據庫，我得到一個「內部服務器錯誤」，不知道爲什麼。我正在使用上傳表單獲取用戶數據，然後使用上傳處理器文件將數據寫入服務器。該表格基於在線工作教程，因此一切正常，但每當我添加SQL代碼時，它就停止工作。我的代碼如下，我感謝你的時間看着它。內部服務器錯誤與SQL代碼

內部服務器錯誤？你有沒有先檢查你的.htaccess文件？ –

是的，.htaccess文件沒問題。有什麼具體的，我應該檢查它嗎？ –

我已經回答了你的問題。一探究竟。確保你正確地使用你的.htaccess。或者如果你不確定.htaccess。刪除它並嘗試。 –

你有這樣的代碼在你的第95行：

header("Refresh: $seconds; URL="$location"");

應

header("Refresh: $seconds; URL=\"$location\"");
