Thanks Marlin, Luuk and C. for your replies.
I'm trying to work with them but I am a beginner and this is a tricky
problem.
C. - a couple of things, I'd like to keep it simple with a single
directory for the moment because other things (code) rely on this fact
at the moment.
Also I'm only allowing users to upload images. I just need a certain
php file to be created everytime the form is submit. And I need it to
have a sequentially increasing number for it's name taht is somehow
kept on a table or sourced from a table so that I can reference this
number to the submitters name in future.
I'll look through the code again, just not sure if copy is best if I
already have the file I want creating on the server, and just to copy
it and rename it on form submit.
.... I've just been thinking and maybe I have to make this form a 2
step process, maybe ask them half their details, then click next (this
will create a row on another tbl containg 'persons name', 'unique
incremental file number' (issued on input to db) and there telephone
or something...
....the second part of the form will look down the table for the
'unique incremental filenumber' where persons name = bob, and
telephone = 2123456789 (and it will already have these details (bob
and tel) from the first half of the form) - then it will have a unique
id for that form submission and the number retrieved can then be used
to rename the copied file on the server and rename the attached
image...
Hassle that it's a 2 step form but might work - what do you think?
If there's a way for this to work then I just need to figure out how
to copy a file already on the server to a new location and rename
(I'll check your suggestion Luuk)
Thanks
