hello every one,
can anyone send me a sample code for file up load.
please send me the code for cgi and html part.
Regards
Max
Do you have a perferred language?
Attached is a test python one I had lying around. upload.py is a dirt
simple one, upload2.py uses a callback so you get information as the
uplaod is going on.

Thanks for your response,
but i dont want to use python or any other script.
I can use clearsilver C API with cgi application .i just want to know
whether it is possible or not.If any one have a sample application
please upload

Yes, its possible. The code is obviously similar to the python from
before. The key point is, your HTML code must have a FORM element which
has the extra parameter for using multipart/form-data:
<form name=upload method=POST enctype="multipart/form-data">
<input type=file name=myfile>
</form>
Then, as normal, you need to call cgi_init and cgi_parse. That will
process the upload, placing the data in a file on disk in the /var/tmp
directory. You can change the directory the upload data goes into by
setting the HDF variable Config.Upload.TmpDir to something else.
Normally, the file is "unlinked" after being opened. This means the
file is only available to your process, and will be deleted as soon as
the process is ended. You can set Config.Upload.Unlink to 0 to stop
this behavior. If the files aren't automatically unlinked at creation
time, they will be cleaned up when cgi_destroy runs, but that won't
happen if your process dies prematurely, of course.
Normally, you can access the data in the file by using the
cgi_filehandle() function. This will return a FILE*, which you can use
to read the file on disk. Arguments are your CGI and also the form
element/query name, ie in the above example, that would be "myfile".
You can also get more information about the file, if its available. If
the browser provided a Content-Type with the upload, it'll be in the
Query.myfile.Type variable. The filename on the client as provided by
the browser will be in the Query.myfile variable. If you are not in
unlink mode, the filename on disk will be in Query.myfile.FileName. The
latter could be used to say link the file to another place on disk, for
instance.
You can get information during the upload (in cgi_parse) by setting up a
callback via cgi_register_parse_cb. There's a lot more information
about all of this in the comments in cgi/cgi.h

hello everyone.. hope all u r doing great.. i am new to this
clearsilver.. Now, I am in need of a file upload and a file download..
I cant find any more help from any other sites.. I have to use
clearsilver c api's for this upload process.. Can any one help me to
get a start with some sample codes....
Thanks in advance.
jeevan
Hmm, second request for file upload help in as many days.
You can see my previous response here:
http://tech.groups.yahoo.com/group/ClearSilver/message/1201
File download is just like via any CGI, you probably want to do all of
the output yourself (ie, first print out the headers, probably
Content-Type and Content-Length, then an extra newline, then the file
contents). You can use stdio (ie, fwrite/printf) or use the wrappers
(especially if you're using FCGI, you'll need to use the wrappers),
which are defined in cgi/cgiwrap.h, cgiwrap_writef() and
cgiwrap_write().

http://www.fiction.net/blong/
Mr.Brandon, Thank you for your immediate response. The file download worked perfectly...!!!!!!!!! I have gone through your replies for file upload. In fact, I didnt get that Python code. I could not make it to write using C API's. Can you tell me something about cgi_register_parse_cb(). Why should we have to register a callback? I am a bit confused with the parameters.. like void *rock. Where can I get more details about these API's. Even the comments in the source code is same as that in the clearsilver webpage.

hello sir,
i have created a html file with following tags,

<tr class="ch_fl1">
<td class="input">
<input type="file" id="file1" name ="file">
<input name="filebtn" type="submit" value='submit'>
</td>
</tr>
</form>
and in my upload.cgi file i have written as,
int main (int argc, char **argv, char **envp)
{
NEOERR *err;
CGI *cgi;
char *cs_file;
char hdf_file[255];
char *p;
FILE *fp,*k;
cgi_debug_init (argc,argv);
cgiwrap_init_std (argc, argv, envp);
err = cgi_init(&cgi, NULL);
if (err != STATUS_OK)
{
cgi_neo_error(cgi, err);
nerr_log_error(err);
return -1;
}
err=hdf_set_value(cgi->hdf,"Config.Upload.TmpDir","var/tmp");
err = hdf_set_value(cgi->hdf, "Config.Upload.Unlink", "0");
err = parse_rfc2388 (cgi);
if (err != STATUS_OK)
{
cgi_neo_error(cgi, err);
nerr_log_error(err);
return -1;
}
err = hdf_write_file(cgi->hdf, "myhdffile.hdf");
err = cgi_display (cgi, "update.cs");
if (err != STATUS_OK)
{

return -1;
}
return 0;
}

Has anyone successfully compiled CS under Visual Studio 2008 (VC++ 9.0)?
I know it's compiled for Windows using MingW (gcc++), but I'm
considering developing a Qt-based C++ wrapper around CS in VC++ and I
don't want to deal with lib conversions or issues between MingW and VC
to integrate with my other libraries smoothly.
Any insight would be greatly appreciated.
