Extension for Symphony 2. Provides an upload field which allows multiple copies of a file to be uploaded to the same location.

Field: Unique File Upload

This extension, just like the Hashed Upload Field extension by Rowan Lewis, provides an upload field which allows multiple copies of a file to be uploaded to the same location. It will retain the filename and append a unique ID to it.

The extension uses PHP’s preg_replace function and will crop the filename (i.e. w/o file extension) to a fixed length.

Origin

This extension is a variation of the 'Hashed Upload Field' extension by Rowan Lewis.

Installation

1. Upload the 'uniqueuploadfield' folder in this archive to your Symphony 'extensions' folder.

2. Enable it by selecting the "Field: Unique File Upload", choose Enable from the with-selected menu, then click Apply.

3. You can now add the "Unique File Upload" field to your sections.

The Clean Filename

From version 1.6, this extension provides an additional "clean filename" in the XML output (for display purposes).

Downloading Files with the Clean Filename

If you want to download files named with a clean filename, put the following .htaccess in your upload folder. If the relevant Apache modules are available, your browser will be asked to download the file under its original name.

Options -Indexes

<IfModule mod_setenvif.c>
    <IfModule mod_rewrite.c>
        <IfModule mod_headers.c>
            SetEnvIf Request_URI "([^\/]*)(\.[^\.]+)$" FILENAME=$1$2
            SetEnvIf Request_URI "([^\/]*)(\-[a-f0-9]{13})(\.[^\.]+)$" FILENAME=$1$3
            Header set "Content-disposition" "attachment; filename=%{FILENAME}e"
            UnsetEnv FILENAME
        </IfModule>
    </IfModule>
</IfModule>

That way the unique filename can be entirely hidden from users:

• Alice uploads report.pdf
• Symphony renames it to report-4415297e3af8c.pdf
• Bob still ends up with report.pdf on his machine after downloading the file

uniqueuploadfield's Issues

Foreign characters in file names disappear in datasource => cannot display images with foreign names

For example

/uploads/屏幕快照-2013-06-20-5.31.4-51c380fc0ecc3.png
/uploads/이수혁2-51cc9fa5c986f.png

will actually show up in the datasource as

/uploads/-2013-06-20-5.31.4-51c380fc0ecc3.png
/uploads/2-51cc9fa5c986f.png

However, in admin, the section with the files links to and displays the image just fine! (using image index preview). SBL fields in other sections however, show the incorrect 2-51cc9fa5c986f.png

Not sure if this is a uniqueupload problem or a Symphony problem in general

Marking compatibility with Sym 2.x/2.6

(Because I haven't been making enough noise already today.)

This is working fine for me in 2.6. I think extensions should now be marked with a max of 2.x.x.

Error message when 'upload_max_filesize' or 'max_file_uploads' php directives are smaller the size of file being uploaded.

Current error message: The destination directory is not writable. Please check permissions.

The core functionality appears to be already included in Symphony 2.4 upload field

Hi, just a heads up: I believe this functionality is now part of Symphony 2.4. It would be good to have this mentioned in the README / repo description to warn people that the extension is not needed in versions >= 2.4

Updater required for compatibility with Symphony 2.3.3

The extension must incorporate an update mechanism similar to Symphony's updater for the (core) Upload field, due to changes in Symphony's path handling in the database.

Updater function for Symphony 2.3.3 does not get triggered

The updater function's version check is buggy. Fix is on the way, will release 1.8.1.
