$_files

I have a form that has multiple text fields and one file field that reads:

<INPUT TYPE=file NAME=userfile>

Upon submitting, I want the script to check and see if any file was added and if so, do this, if not do that. I've tried the following:

if ($userfile) {
   do this
} else {
   do that
}

...but the script acts as if a file was uploaded, whether one was or not. If I change the if statement to a input text variable, it works fine so I have a feeling I'm not working this file input right. There must be a different trick to telling PHP that there is no file? Help please!

Try This:

<?php

if(!empty($_FILES['userfile']))
{
   echo "Upload";
}
else
{
   echo "No Upload";
}
?>

I think I just answered my own question. I'll post my conclusions here though, as a learning experience. Instead of:

if ($userfile) {
   do this
} else {
   do that
}

...I did this and it worked:

if (file_exists($userfile)) {
   do this
} else {
   do that
}

Apparently an input file field always passes whether there's a file or not, so checking the file field name always passed as yes, even if there was no file. Using file_exists checks for an actual file, not just whether the file input field was submitted. Good to know.
