[RESOLVED] check isset with array

[sks1024]

I have a form with 5 file uploads

All filenames are userfile[] in the form.

i.e

<input name="userfile[]" type="file" />

how can I check on the next page if each one of these has been set like with isset

I dont know how to reference the array of files

example

if(isset(userfile[0])) {

do something
}

if(isset(userfile[1])) {

do something
}

Can i reference them this way?

Thanks

Might be easier to do with a foreach. As a simplistic example:

foreach($_FILES['userfile'] as $file)
{
   move_uploaded_file($file['tmp_name'], 'uploads/'.basename($file['tmp_name']));
}

I dont want to actually upload the file yet.

At this point all I need to do is check to see if there was a file actually uploaded for each file element of the form.

I want to do something different with each file if it has been uploaded

Thanks

Eh...ignore what I posted above, anyway. I always screw up the way $FILES is indexed. :rolleyes:
If you want to do something different for each file field, it would be something like:

if(!empty($_FILES['tmp_name'][0]))
{
   // process first field
}
if(!empty($_FILES['tmp_name'][1]))
{
   // process 2nd field
}
// etc....

Actually that would be $FILES['userfile']['tmpname'], then $FILES['whatever_name_the_next_file_input_was_given']['tmpname'] and so on.

Actually, it wouldn't be; it would actually be something like $FILES['userfile']['tmp_name'][0], $FILES['userfile']['tmp_name'][1], etc. (NogDog simply forgot the ['userfile'] in his example).

Heh...I told you I always screw it up. :p I usually have to actually read the manual to get it right. :eek:

Oh, you're right. I missed the brackets in the name attribute and missed the whole point tof the question :s
