Answer 1

Are you getting any error/warning while uploading the attachment?

Please try to debug the code after this statement: if(!empty($_FILES["attachment"]["name"])){ , like weather you are getting the attachment data in $_FILES.

Check permission of the upload directory weather it's 777(read,write,executable) or not, if not then you should give permission to the directory.

One more thing to check is: max_execution_time and upload_max_filesize in you php.ini file, increase it's value

Answer 2

The unlink function is used to delete files on the server, you can do well to remove or comment out that section.
