I'm using type="file" in the form, but when i submit the form, the page that follows I get this..

/var/www/domain/public_html/WEB-INF/railo/temp/tmp-20

using..

<cfset thisimage = listfirst(#form.imagefile#,".")>

<cfoutput>#thisimage#</cfoutput>

how would I parse out the name of the file and its extension?

Again, just a guess ... but I'd imagine Railo is like the Adobe version.  All files are uploaded to a temp server directory first and given a temporary file name.  That's what you're seeing when you look at #form.imagefile#.  

You then have to use cffile "upload" to get access to the real file name (and move it to desired directory). Use CFFILE variables like #CFFILE.serverFile#, #CFFILE.serverDirectory# to access the file name and extension ...

ie <cffile action="upload" filefield="form.imagefile" .....>
<cfdump var="#CFFILE#">

To clarify the last comment.  First upload.

      <cffile action="upload" filefield="form.imagefile" .....>
 
Then use the cffile variables:

    #CFFILE.serverFileExt#
    Extension of the uploaded file on the server (without a period)

   #CFFILE.serverFileName#
   Name of the uploaded file on the server (without an extension)

You can use

#cffile.serverfile#

you will get complete file name along with its extension.

They want the name and extension separated.  Fortunately, cffile has variables for that too ;-) See my previous post.

Hi, if you want the original file name (name of the file, as you select before uploading), you can use

#cffile.clientfile# ==> complete file name with extension
#cffile.clientfileName# ==> File name (as it was in your system before uploading) without extension
#cffile.clientfileExt# ==> file extension

Personally, I've never found use for client variables.  99% of the time what you're looking for is information about files on your *server*.  That can only be obtained from the *server* variables I mentioned earlier:

    #CFFILE.serverFileExt#
   #CFFILE.serverFileName#

Based on the original question,  you almost certainly should NOT be using the client variables.
