Get FILE NAME and EXTENSION??

Hi everyone! I'm trying to put file names into variables which later I put into my DB (MySQL) as text (only the filename and the extension). I tried to use the upload format form before: <form ENCTYPE=\"multipart/form-data\" ...> .... <input type = FILE name =\"file_name\"....> ..... When I retrived the value of the variables, I did not get the FILE NAME and the file extension. What I got is all the path of the file and the file name changed into .TMP or some sort. How do I retrived file names and it's extension in this situation? note: The original file extensions that I want to get are mostly .jpg or .gif. thanks for reviewing my email. regards, Dani
