uploading file????...

I use ftp for upload images but I have a problem when do that in the remote server. when I leave the file field empty a path is registered in the DB when in this case the field reference to the image must be NULL.


Example:
regist images/links/35_ in the DB and upload a file named 35_ ????


Code of the destination file:

$destination_file = "public_html/images/links/".$arrx["link_ID"]."_".$_FILES['file']['name'];


The problem is in this line, I'm sure but I don't know what to do resolve the problem!!! Can You help me??

If you are using ftp to upload the files, then it has nothing to do with PHP.

You are wrong!!! In PHP code there're ftp functions to upload files!!!

Ah, I see what you mean now. If you could post the rest of your code I can help.

I think I already have a solution but very thanks for your attention!!
