Questions answered by this recipe

How can I display the size of attached files?

Description

Custom markup to get the file size of attached files

To install this recipe:

download Attach:AttachSize.php Δ
copy it to your cookbook directory
add in your config.php or farmconfig.php this line:

include_once("$FarmD/cookbook/AttachSize.php");

Notes

File sizes are all returned as the nearest whole number of KB, or the number of bytes below 1KB. It doesn't show MB, but then attachments are generally not that large anyway. Possible future enhancements could improve this.
Formatting is hard-coded.

Note that as it is now, the recipe will allow the presence & size of any file accessible via the PHP script to be determined. To fix, take a look at what HandleDownload() in scripts/upload.php does when downloading an attached file. Also, for a relatively robust file size > string converter, take a look at Attachtable's AttachFilesizeString(), eg. from line 269 of this Δ. —Eemeli Aro May 27, 2009, at 02:46 AM

The presence & size disclosure vulnerability is now fixed.

I didn't bother with the more involved formatting because (1) uploads over 10MB are highly unlikely (do I really need to format petabytes correctly?) and (2) someone would very quickly come along asking for additional formatting like KiB, "octets", etc. Maxim ? 2009-05-27
