[SOLVED] Renaming an uploaded file

ballouta · July 31, 2008

Hello

I have this uplaod form, it is 100% working but i need now to rename the uploaded file so it is NOT more than 9 characters.

I searched google but samples i found didnt work correctly with me.

I used this:

$position=9;

$post = substr($name,$position,9);

$name = $post;

if I echo the $post, it gives H.ask

and the bad thing is that I am still getting the file to my email in its long name!

here's my code, the file i am uploading is: XXXXXXXXXH.ask

PLEASE help
