file upload: correct "copy" syntax?

[Anon]

I'm having some trouble with uploading files. I have a form that I'm using to upload two files at once, an image and a thumbnail of that image. The code I used in the upload form is as follows:

---

<form method="post" ENCTYPE="multipart/form-data" action="addtosql.php3">

<INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="300000">

full-size image<br><input type=file name=userfile size=30>
<br><br>

thumbnail image<br><input type=file name=userthumb size=30>

... some other fields ...
</form>

---

The code in addtosql.php3 which processes these images is as follows:

---

copy($userfile,"$gallery/" . "$userfile_name");
copy($userthumb,"$gallery/thumbnails/" . "$userthumb_name");

---

The first full-size image is uploading with no problems. However, for some reason it's copying the full size image to the thumbnail image. So th_filename is not being created as the thumbnail image, but rather as the full size image.

I'm suspecting it has something to do with the fact that I have two files uploading from one form.

If anyone has ideas/suggestions, I'd be very grateful! Thanks!

Just a thought but aybe if you try deleting the first temp file before copying the 2nd it might have some effect like:
The code in addtosql.php3 which processes these images is as follows:

---

copy($userfile,"$gallery/" . "$userfile_name");
unlink($userfile);
copy($userthumb,"$gallery/thumbnails/" . "$userthumb_name");
