I’m actually going to close comments on this post as it is specific to 0.9.7, and we’re up to 1.2 now. (See the release announcement for 1.2).

I think using a category page as a callback URL may cause problems for you with the “invite friends” link if you’re showing it – but maybe not. It’s a use case I’ve never tested, is all.

It certainly won’t work, as currently written, with multiple instances. You could potentially create a copy of wpbook, namespace all the functions, and run two alongside each other. (WordPress would have to see them as separate plugins – different name for wpbook.php, different folder, and no conflicting function names).

It should be possible, in other words, but I don’t see it ever being a feature in a “supported” or “official” release of the plugin.

I realized that one can give the callback URL for, lets say, a category, and thus get only the posts for that very category on the facebook page.

Is it possible to run two instances of WPbook, and get two categories listed as separate blogs on facebook? I’d like to run a general (with all the topics) as well as a specific one for targeted users.

You can get the SimpleXML library backported to PHP4 here: simplexml44

And put the whole “simplexml44-0_4_4″ directory inside:
/wp-content/plugins/wpbook/themes/php4client/

Fatal error: main() [function.require]: Failed opening required ‘simplexml44-0_4_4/class/IsterXmlSimpleXMLImpl.php’ (include_path=’./:/usr/share/php/’) in /home/mhd-01/www.ilviruscheparla.org/htdocs/wp-content/plugins/wpbook/php4client/facebookapi_php4_restlib.php on line 34
I uploaded the whole directory on wp-content/plugins and activated the plugin from admin panel.
the canvas URL is http://apps.facebook.com/ilviruscheparla
thanks a lot

I first changed my theme to a couple of different themes with no change.

I then set my permalinks to the default ? links. When I did this, I got a fatal error for SimpleXML. This led me to realize that I was using PHP 4.x. I changed to PHP 5 and all is well.

I put my permalinks back on.

Thanks for the help!

Basically the plugin looks for a querystring parameter (fb_sig_in_iframe) which Facebook automatically adds to the callback url you provided when you set up the application.

Might be some kind of plugin conflict – can you try eliminating other plugins?

Do you have something custom set as a front page?

I’m working on setting up my wpbook app. Things seem to be going ok (WP 2.7) except that my facebook app is retaining my blog theme and not the facebook style theme?

Is there something I need to set to make that happen?

My facebook app is at http://apps.facebook.com/fireeducator/

Thanks for the great work.

Looks like that causes a problem on servers without curl installed – perhaps that’s why I haven’t seen it yet.

I’ve added in the suggested fix on my local copy, and will deploy it with the next release of WPBook, but there may still be issues for some folks who have other Facebook-related plugins which also include the library, and may have non-updated versions.

Thanks for the heads up.

Search the developer forums on facebook for

API Broken – empty string reponse, non-curl only

It was entered today.

The php5 client I’m distributing comes directly from Facebook’s developer wiki, and I’m not seeing any behavior in the app that would suggest to me that it has a bug.

(I’m not saying it doesn’t have a bug, just that I haven’t seen any behavior that doesn’t work in the parts of the API I’m using. Have you?)

Is that not working in your installation? Are users able to leave comments from the Facebook side?

If it is returning null, it may be an issue of the facebook client failing to initialize, which may cause other problems as well – what’s the URL of your facebook app?

$rs = $facebook->api_client->fql_query(“SELECT name, pic FROM user WHERE uid = “.$user);

in comments.php

$user is set with a #

dunno why

pretty cool so far though!
