happen this...) i want the two files in my database...what is the solution for this...

I use to do this:

I change the name of the uploaded file when saving. The new name is generated using the upload database record ID, so it's unique.

Example:

File Name: manolo.xls

Insert query:
insert into uploaded (id,usr,name,dateuploaded) values (NULL, 213, 'manolo.xls', now())

Then I recall the last insert ID:
$newname=mysql_insert_id().".file";

This will generate a new name like this: 158.file

That's the file name you save.

And when you want to deliver the file as a download, just retrieve the actual name from the DB.

;-)

Thank you for your reply...

Take a look at my multiple php upload tutorial as well. I might help you out on the concepts of doing this.
