Hi Simon:
Well, you helped me figure out a bit more. Your script works, but not in
the arrangement I'm using (maybe I need to rethink).
I think my problem is I'm trying to trigger the download by reloading the
same page. I have the lcserver code near the top of the page (note I
simplified your code):
<?lc
if number of lines in the keys of $_POST > 0 then
put header "Content-type: application/zip"
put header "Content-Disposition: attachment; filename=sound.zip"
put header "Content-Transfer-Encoding: binary"
put url "binfile:files/sound.zip" into theFile
put theFile
end if
?>
Then there'a simple form on the page:
<form method="post" action="index.lc">
<input type="hidden" name="get" value="true"/>
<button type="submit">GET FILE</button>
</form>
If I place only (the modified version of) your code on a simple page and
load it in a browser, it downloads the ZIP as expected. When I run all of
the above on a page and press the submit button, the raw code of the ZIP
gets written to browser window (Chrome OS X).
So maybe I need to figure out another way of loading a page that contains
the download code. I've tried using redirects and get the same problem --
raw code in the browser. I don't get what the difference is between
loading a URL via the browser's address field, and "put"-ting a URL via
lcserver.
