File Manipulation Question

TheMayhem

move_uploaded_file($_FILES['image']['tmp_name'], $uploads.'/'.$_FILES['image']['name'])
or die ("Couldn't upload ".$_FILES['image']['name']."\n");

Today I learned the wonders of file manipulation. So for my constant project I'm copying this file over to a directory. My question is a person will come up with the name of like weather.jpg for a picture of weather. But to make things easier on me to classify and such I'd like to make it so that where the above thing executes but instead of naming the file as what the user specifies. I just rename it to their userid, which would be $user[id].extension (gif, ect.). Pretty simple but I didn't say anything in the php guides jump out and tell me so I figured someone here would know.

If you know you're setting the user id to: $user[id], then look at the following post. It's for images mainly, but then again it seems that's what you're uploading.

Basically, you could also use rename() to rename the file as you see fit.

You don't have to use $_FILES['image']['name'] as an argument to move_uploaded_file(). You can use whatever you want. I have done this in the past using something like:

$sessionId . "_" . $FILES['image']['name']

so I have the session id as well as the original file name in the new file name.

I'm still somewhat confused on what to do. So maybe you guys could show me how to do this???

With the statement I posted originally how can I get it so if a person calls an image for example
smiley.gif to their userid which is current $user['id'] which would equal 43.gif or whatever their id # is?

Like I said, you can name the file whatever you want while using move_uploaded_file().

example:

move_uploaded_file($_FILES['image']['tmp_name'], $uploads . "/" . $user['id'] . "gif");

This assumes every file uploaded is a gif which is probably not going to be the case, but you get the point.
