Problem with uploading

[jose9]

Hi everyone,
Will appreciate your advice for this issue.
I posted a thread in the Database section of the forum a few days ago.

I encountered this problem when trying to use a upload function, which is part of a source code that i got from the Internet. I'm using it as part of a portal.

The error message that i get is:

Warning: filesize() [function.filesize]: stat failed for C:\WINDOWS\TEMP\phpA2.tmp in d:\inetpub\wwwroot\spoapps\ppp\uploadtrytest.php on line 76

Warning: fread() [function.fread]: Length parameter must be greater than 0 in d:\inetpub\wwwroot\spoapps\ppp\uploadtrytest.php on line 76
Error, query failed

I did try out this function previously and it worked perfectly fine.
I believe that filesize is definitely greater than 0.
The only thing that confuses me is this C:\WINDOWS\TEMP\phpA2.tmp.

Is this a temporary storage location for the contents of the uploaded file before it is transferred to the uploaded folder on the server?

Advice is greatly appreciated!

First of all I advise you to do it yourself, and only grab snippets to learn.

The piece of code you're using apparently doesn't even check if the upload succeeded and if a file really came through. That's a mighty crappy piece of code you've got there, my friend.

The filesize is zero because the filesize() function couldn't get the filesize. Probably because the file isn't there.

If you want to know how this works, try this:

echo "<pre>".print_r( $_FILES, true )."</pre>";

That way you get a clear image of what exactly is happening in your script when you upload something. You can also check for errors using the constants provided.

Don't forget to use these functions:
is_uploaded_file()
move_uploaded_file()
They make sure nobody's fooling your script into saving malicious stuff.
