[Tclhttpd-users] File upload problems...

[Anders N. <an...@di...>]

Hi.

I'm trying to implement a file uploadpage with cgi. I've taken
a look at the demo that comes with the tclhttpd, especially the
testupload.tml file. For me, since I don't really get the .tml
workings, the main part of recieving the uploaded file is this:

foreach {n v} [ncgi::nvlist] {
  append html [html::row $n [html::tableFromList [lindex $v 0]]]
  append html [html::row $n [ncgi::value $n]]
  append html <tr>[html::cell "colspan=2" "<pre>[html::quoteFormValue
[lindex $v 1]]</pre>"]</tr>
}

which nicely breaks down to:

foreach {n v} [ncgi::nvlist] {
  append html "name: $n "
  append html "value: $v "
}

for the sake of clarity. Now, that works just fine, but when I
try to put that into my own ncgitest.cgi file, it doesn't work
as in the .tml file above. When I run my own cgi-script, I don't
get any values in the $n variable, and in the $v variable I get
the whole thing.

Ie. the .tml file gives these values:
$n: hide_me
$v: {content-disposition form-data name hide_me} {hello, world}

while my cgi-file gives these values:
$n: <empty>
$v: {} {Content-Disposition: form-data; name="hide_me" hello, world }

Also, when I try to upload a little bigger imagefile the .tml version
handles it nicely, but my cgi-file just hangs...

What am I doing wrong, or what is the .tml version doing that I don't?
