Bug #77372 [Opn]: Relative file path is removed from uploaded file

Edit report at https://bugs.php.net/bug.php?id=77372&edit=1 ID: 77372 Updated by: cmb@php.net Reported by: nospam at unclassified dot de Summary: Relative file path is removed from uploaded file Status: Open Type: Bug Package: *Directory/Filesystem functions Operating System: Windows 10 PHP Version: 7.0.33 Block user comment: N Private report: N New Comment: Hmm, the webkitdirectory attribute[1] is part of the “File and Directory Entries API” which is a very recent *draft*, so I wouldn't assess non-compliance with this feature a bug in PHP per se. Anyhow, the relevant code[2] that causes this behavior is due to a quirk of IE, namely that even recent versions of IE 11 allow to “Include local directory path when uploading files to a server”. However, while the code originally just catered to backslashes (like the comment still indicates), it has been replaced with a more general _basename()[3] which also caters to (forward) slashes. So, at the very least, the comment is wrong.

In Firefox, the POST request correctly contains the relative paths of all uploaded files. In PHP, the paths are removed and only the file names are available. $_FILES['files']['name'][...]: Actual value: 'file.png' Expected value: 'sub/dir/file.png' This makes the entire directory uploading feature unusable because the structure gets lost and file names may even become duplicate and useless. Note, I have searches for "upload webkitdirectory" but only got tons of unrelated results, so I might have missed a real duplicate. Please improve your search if you want to avoid duplicates.
