こんにちは、私は PHP が初めてで (私は asp.net 開発者です)、友人のために Web サイトを開発する必要があったため、PHP に切り替えました。現在、自分の Web サイトのフォルダーに音楽ファイルをアップロードしようとしていますが、このエラーが引き続き発生します。
注意: 「未定義のインデックス: 5 行目の C:\xampp\htdocs\sitename\admin\uploader.php の Uploadfile」
次の手順を試しました：
- max_upload_filesize と post_max_size を「1028M」に設定します。
- form タグに "enctype="multipart/form-data" を追加しました。
- 「print_r($_FILES);」を試してみました 配列は空を返し続けます。
- 新しい Web サイトでアップロード スクリプトを使用したところ、正常に動作しました。
- 非常に多くの異なるスクリプトをオンラインで試しましたが、どれも機能しませんでした。最終的にこれを試しましたが、まだ同じ問題に直面しています。
以下は私のコードです：
