Hi Tim,
Here is a very simplistic way of checking for a file on your server. It
assumes your mp3 files are in a 'programs' folder that resides in the
'document root' folder. This script as it is here would be in a .lc file
on your server. You pass it a filename in the url and it tells you if
the file is in the programs folder or not.
So the url would look something like this:
http://my.programserver.com/check.lc?1234.mp3
The text of the 'check.lc' file:
<?lc
set the errorMode to "inline"
put $_SERVER["QUERY_STRING"] into tFilename
put $_SERVER["DOCUMENT_ROOT"] & "/programs/" & tFilename into tPath
if there is a file tPath then
put "Found file" && q(tFilename)
else
put "Did not find file" && q(tFilename)
end if
?>
<?lc
function q pString
return quote & pString & quote
end q
?>
This is most likely not exactly what you need, but maybe it'll give you
a starting point.

Hi,
On-rev.com hosting, using LC server to present a list of our AM/FM
radio programs for people to listening to on-demand.
Out of a month's 20 programs, 3 or 4 might not get uploaded due to
copyright issues, etc. Also, mp3's are not on the on-rev.com server,
but another hosting service we use as well.
Filenaming is standardized, so I know the list of programs. I want to
hit the server, if the mp3 files exists, present it as an <audio src=,
if the mp3 file does not exists, present a "Sorry, program not
available" message.
If I wanted to check on the existence of a small text file, it would
be fast enough for me to just get it, put it into a variable and see
if the variable has anything in it. But mp3's are too big, so too slow.
Locally, I would simply write "if there is a file 'filename'..." --
what's the equivalent command for checking on existence of a file on a
server?
Thanks in advance.
