From 18bdba4700e268f713df7ddda1b92d37bfef3cf9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] + replaced `for` with `foreach` to allow parsing of
 myvar[ID1],myvar[ID2] instead of myvar[] - this gives the option to work with
 IDs injected into the array + added option to make the original filename
 lowercase on the destination file. + added option to provide destination
 filemask while using the {i} which represents the iterator in the foreach
 (Which is the given ID)

I'm new to git hope I commited it right! ;-)

+	Copy MY_Upload.php to your application/libraries directory. If you are using a prefix other than MY_ for your classes and/or alternative file paths, adjust accordingly.
+
+	Usage Load the Upload class as usual, in your controller call the function do_multi_upload(). If you are uploading a single file, it'll default to the regular do_upload() method. In the form, set field names to array (e.g. name="userfile[]")
