チャンクドのアップロードは、私が取り組んでいるプロジェクトでうまくいくようにしてきました。すべての集中的な目的のために、自分自身を教えている完全なnoobと、ウェブサイトから手動アップロードテンプレートを使用しています。また、従来のサーバーサイドのサンプルファイルを使用して、コードの仕組みを理解し、私が構築する完全に機能的な例にしてください。私はほとんどのものを動かすことができました。ファインアップローダーでファイルをアップロードするとアップロード成功後にチャンクを結合/マージできない
チャンクを使わずにファイルをアップロードすると、正常にファイルをアップロードすることができました。ただし、チャンクを使用すると、ファイルをチャンクしてフォルダを私のチャンクディレクトリに置くことはできませんが、チャンクをまとめてFilesディレクトリに置く方法はわかりません。
私のFirefoxコンソールは私にこの応答を与え、ファイルをチャンク私のチャンク成功のエンドポイントが自分のコードに含まれているかどうかにかかわらず、チャンクの成功のエンドポイントが正しく設定されていないか、それとも何かに沿って何かがあると思うようになる。
[Fine Uploader 5.11.8] All chunks have been uploaded for 0 - finalizing....fine-uploader.js:162:21

[Fine Uploader 5.11.8] Finalize successful for 0
私は無駄でこれを研究して、約2日間を過ごしましたが、私はエラーを取得していないようですが、私はそれが私自身でこれを理解することに来るとき、私はかなりNoobのよ言ったように。どんな助けも大いに感謝しています。

単に「機能しません」と言っても、ヘルプを提供するには不十分です。 _specifically_何が間違っていますか？どのような症状が見られますか？どのようなログメッセージがさらに問題を照らしていますか？さらに、ここに含まれているコードは不完全です。アップロードを処理し、チャンクを結合しようとするコードはどこにありますか？ –
私の謝罪は、すべての集中的な目的のために私はこれでかなりノブです、私は私のHandler.phpを含めることを忘れていた、私はそれを含めるために私の質問を編集した、成功したチャンクアップロードで私のfirefoxコンソール応答、私の問題を少しはっきりさせようとしましたが、物事を理解しやすくする方法を教えてください。もし私が欠けているものがあれば、それを含めると有益でしょう。基本的には、正常にアップロードされた後にチャンクファイルを一緒にマージする方法がわからないので、チャンクを正しくセットアップしていないと思うようにします。 – GrandStar
ファイルが問題なく結合されているようです。 –
