[thelist] PHP file upload problem

[Jay Blanchard]

[snip]
This was all working perfectly yesterday. Sometime today, the $_FILES
autovariable seems to have reversed itself - if nothing is uploaded
using either file field, $_FILES contains both first and second arrays
(both empty of data). For any file that is uploaded, that array is
empty. (If I send a file using the second file field, then $_FILES
contains an empty "first" array, but no "second" array exists.) If I try
to upload two files, then $_FILES does not exist at all.

Any suggestions for what else I can check or what could be wrong would
be vastly appreciated.

It sounds to me as if the upload form is the problem. If the back-end
code (that you posted) was working fine and hasn't been messed with then
perhaps your other code has been messed with.
