File create / download question

[jasonyoung]

I have a text file which stores MAC addresses. I would like to have a form prompt for the last six characters of the MAC maybe in a text area field (the first six will never change so I'll code them statically) and upon submitting, generate a text file with the MAC's listed in the order entered, with colons at the normal spacing. The output file should look like this:

00:10:36:0E:21:A2
00:10:36:20:14:33
00:10:36:05:1F:44
00:10:36:04:71:5B

and it could have several hundred entries.

I think I can do the coding to get the file created but pretty much don't know where to begin putting the values into the file and then make the file automatically pop up with a "save as" dialog box so I can choose to save it locally instead of to the server.

Sounds easy enough, right? I would greatly appreciate ANY direction you all could provide.

Thanks!

Send the proper header and there's not writing to a file needed. Just output the contents of the variable you create with all the MAC address entries, send the header as text or whatever (google it) and define the filename you want to use.
