validate file upload

[bdichiara]

I'm looking for a simple way to check to see if a file input field has a value. I have an upload field, however, if they choose to put something in that field, it will replace the existing item in the database. This is what I want, however, if they leave it blank, it erases the existing item in the database. How can I check to see if the file input field has a file in it?

I've tried:

if(empty($_FILES['attachment']['name']) || $_FILES['attachment']['name'] == ""){

Thanks!

Check the $_FILES error variable, if the value is 4 then no file was uploaded.

<?php
if ($_FILES['attachment']['error'] == 4) {
    //no file uploaded
}
?>

File error code meanings can be found on the Error Messages Explained page in the PHP manual.

Excellent Thanks.

I also figured out I had a misspelled variable (attachement instead of attachment)...
