hii..im trying to upload a file and im getting a "Warning: Unable to create 'home/public_html/proj/upload/addUser.php': No such file or directory in /home/gwu7/public_html/uploadThankYou.php3 on line 21"

if(file_exists($userfile)){print "userfile $userfile exists";}else{print "userfile $userfile does not exist";}

if(file_exists($userfile))

check to make sure you have the proper permissions to do such operations within the desired directory..

if you want to take a look at a working version and grab pieces out of there, i have a full .phps multiple file upload script source file located here: http://kdavis.dyndns.org/ccae/multiple_file_upload.phps

it is a fully working script.. just cut and paste it and you are set to go.. change a few settings up at the top of the script.. and walla ;o)
