Hi,
First, I don't really need if this should go to this group or to some
others. It's more about methodology and involves both php and javascript.

Say I went thru a series of forms, each time validating and, in some
cases, manipulating the data (which includes files to be uploaded at a
later point) and saving those in the $_session array, which thus contains
$_POST data as well as $_FILES data.
Now, the last stage involves triggering a form input with some javascript
code

document.the_form.action = path_to_upload_script;
document.the_form.submit();

How can I link the_form to what's in $_session?
I mean, I could put the data in hidden inputs and then trigger the submit
but what about files? I can't place them in hidden fields, can I?

I'm not sure what you mean. How can you have $_FILES data in the
session? Surely the file will be uploaded when the associated form is
first POSTed?

$_SESSION data is already in the server - why would you want to re-upload
it?

ok, i was a tad unclear. What I'm looking for essentially is a way to
pass file input from form to form. Say you browse for a file in multipart/
form-data,then you get an array with its name, tmp name, size and so on,
right? So how do you pass along this information? You can pass along any
input types but the file input type.
The form in which I enter the files is validated by a php script then I
need to keep this information for another form that, upon submission,
will be handled by a perl script. The file's information may be on the
server but not its content because the actual file uploading is not done
yet.

The simple alternative would be to submit the form directly to the cgi
(ie without going thru the php manipulation and reentry) but I'll try to
make this work nonetheless.

session data yes, but not the actual files. I need to make the submit
"aware" of the $_FILES array

You store it in $_SESSION ....

Yeah, 'cause you get that by running the "file" command on an unix system.

Wrong. Whenever you submit a file, it gets on the server - do you think that
the temporary name of the file is created from thin air?

May I suggest using CURL to make PHP post all the data saved in the
$_SESSION, plus the files (provided you moved them out of their temporary
placement) to the perl script ?

Can't be done with HTML/PHP/JS. There is no possible way to set the
value of a file-type input, which is what you need to do. Might be
doable with Flash/Flex.

Yes, the actual files on on the server. They were uploaded when the
user submitted the form with the FILE info.

It's temporarily stored in the temp name. If you don't move it to a
permanent location before this page ends (with move_uploaded_file), the
file is discarded.
