how to trim file path from filename

[andyau]

I am uploading a file to the server and at the same time I want to
place the file name in to a database.

But for the the file to be effective I need to trim the path from the
filename and leave just the filename.

Can anyone suggest how I do this?

It's all part of a google maps mash up.

The page can be found here.

Thanks in advance.

in what language are you doing the job on the server side ?
if you do that with php the file name is in $_FILES['file']
['name'] ... I think

I don't think PHP filesystem functions has a method to return
filepath separators (for example java does...)

But the Java method returns the file path separator in the environment
where the JVM is executing, so probably a server where we are
concerned, but the file path originates from the browser client and so
its separator may be tied client's OS.

You are correct. Sorry about that.

I would still recommend using server side code rather than javascript
on the client for making this split. The package reference by Erwin
Moller above would be how I would probably proceed with something like
this.

Me too. And it is a somewhat uncommon task for (client-side)
javascript. Normally a server program would parse this kind of data.

Indeed, but that can be done using serverside javascript
as requested and on topic:

<% // javascript

var url = 'http://aa.xx/bb/cc/dd.html';

var temp = url.split('/');
var file = temp.pop();
temp.push('');
var path = temp.join('/');

%>

For an URI, yes. But the specifications of a system path are
considerably different (and OS-dependent):

The traditional directory separator is regular slash ('/'), but Winoid
systems generally use backslash ('\'). But a file or directory name in
UNIX may contain backslash as well.

That appears not to apply to all Unices:

$ touch '1/2'
touch: cannot touch `1/2': No such file or directory
$ touch '1\/2'
touch: cannot touch `1\\/2': No such file or directory
$ mkdir '1/2'
mkdir: cannot create directory `1/2': No such file or directory

Your test only indicates that UNIX filenames cannot contain forward
slash. This is logical, because that character is reserved as
directory separator. I don't see any problems with backslash here:

%ls -l
%touch '1\2'
%ls -l
total 0
-rw-r--r-- 1 bart users 0 Apr 3 10:21 1\2
%uname -smr
FreeBSD 4.8-STABLE i386
%

Backslash handling might depend on the shell:

%echo $SHELL
/bin/csh
%
