Adding a comment to a community through the API

[run_ambrose_run]

I opened this as a support request, but it looks like they don't know the answer. Hopefully, someone here does!

I'm trying to create a client that can add a comment to a community post using the XMLRPC addcomment method.

There is discussion about the method here: http://community.livejournal.com/lj_dev/824175.html

When I use it on LiveJournal, it works perfectly with free accounts, both in personal journals and communities. On Dreamwidth, it only works with a paid account and only when posting to one's own journal. If I try to send a comment to a community, I get this error:

No such entry. at /home/dw/current/cgi-bin/ljprotocol.pl line 223

Does anyone know how to resolve this or if Dreamwidth even allows the method to be used on communities?

**edited to add a PHP example**


$request = array();

$username = 'run_ambrose_run';
$pwd = '*******';
$subject = 'Subject of comment';

$this->xmlrpc->server('http://www.dreamwidth.org/interface/xmlrpc', 80);
$this->xmlrpc->method('LJ.XMLRPC.addcomment');

$request = array(array(array(

'username'=> array($username,'string'),
'password'=> array($pwd,'string'),
'ditemid' => array('80257','string'),
'parenttalkid' => array('0','string'),
'journal' => array('dw_dev','string'),
'body' => array('Hello World','string'),
'subject' => array($subject,'string'),

),'struct'));

$this->xmlrpc->request($request);

We have done horrible, horrible things to the XML-RPC protocol. Horrible things. We tried to keep it backwards-compatable, and in most cases we could (not all, but most).

The addcomment method, though, isn't one that was supported in any existing client, so I don't think anyone's tested it since the last time we did protocol work. So we probably broke it and didn't notice. :)

Can you post your code? Someone who knows things better than I do should be able to tell if the problem's on our end (and fix it) or your end.

Thanks, Denise. I've edited my post with some example PHP to post a comment to this entry. If I change "80257" to "303" and "dw_dev" to "run_ambrose_run", it works like a champ.

Awesome. I hope someone will be able to help -- if necessary, will you be willing to help troubleshoot/investigate? The reason we haven't done a lot of work on making sure the protocol does stuff right is because we haven't had anybody really interested in client development -- we've done some work, but not a whole lot.

[run_ambrose_run]

Sure, just let me know what you need.

From looking at the code on our end, we don't support ( or look at ) the journal parameter at all -- the feature was added after we forked from the LJ code a few years back.

I've filed a bug to add this feature at http://bugs.dwscoalition.org/show_bug.cgi?id=3412

You may watch that bug for any fixes, and dw_news or dw_maintenance once a fix is committed for our next code push when the code will be live on the site.

Sorry for the inconvenience,
Dre

Thanks for looking into this. I'll give it another try when the fix goes live.
