フォルダーを正しく表示できますが、フォルダーをクリックして個々の画像にドリルダウンすると、次のエラーが表示されます。
Warning: DOMDocument::load() [domdocument.load]: I/O warning : failed to load external entity "/homepages/2/d333603417/htdocs/development/UploadedFiles/files.xml" in /homepages/2/d333603417/htdocs/development/imagefolders.php on line 25 Warning: Invalid argument supplied for foreach() in /homepages/2/d333603417/htdocs/development/imagefolders.php on line 65
25行目はこの行$descriptions->load($absGalleryPath . '/' . 'files.xml'); and line 65 is this:

私の最初のスクリプトはセッション変数を使用していなかったので、何の問題もありませんでした。ただし、これらを含める必要があるため、これらとforeach
コマンドの間に競合があると確信しています。他の誰かが同様の問題を抱えているかどうかを確認するためにかなりの調査を行いましたが、何も見つかりません。
誰かがこれを見て、どこが間違っているのか教えてくれるかどうか疑問に思いました.
多くの感謝と敬意
