i have the following code for uploading the file on my folder and it is working on localhost, but when i uploaded the code online, it's not working though i have put the correct path. Is there any way i could see the reason or error why?
What about directory permissions for your destination? Have you cross-checked that?
try chmod -R 777 /var/www/your_project_name
This might help :)
Also, check what's your function move_uploaded_file is returning?
"Returns TRUE on success.
If filename is not a valid upload file, then no action will occur, and move_uploaded_file() will return FALSE.
If filename is a valid upload file, but cannot be moved for some reason, no action will occur, and move_uploaded_file() will return FALSE. Additionally, a warning will be issued."
