Another day, another Community Server add-on!
A member in the Community Server forums needs a way to add a statement to every blog post that is syndicated in order to prevent scrapers from "using" their content with no mention of the rightful owner. This seems like a real good idea for anyone, including me, who syndicates their content. Jose Lema came through with the basic idea of how to handle this situation so I figured I would run with it.
The code, as Jose provided, is real simple however I wanted to make it easy to change the "RSS Signature." I figured we could store the signature text in an ExtendedAttribute rather than a config file so here is what I have:
public void Init(CSApplication csa, XmlNode node)
{
csa.PreRenderPost += new CSPostEventHandler(csa_PreRenderPost);
}
void csa_PreRenderPost(IContent content, CSPostEventArgs e)
{
WeblogPost post = content as WeblogPost;
if (post == null)
return;
if (e.ApplicationType == ApplicationType.Weblog && e.Target == PostTarget.Syndication)
{
string sig = post.Section.GetExtendedAttribute("BlogRssSignature");
if (String.IsNullOrEmpty(sig))
return;
post.FormattedBody = String.Concat(post.FormattedBody, sig);
}
}
Now for the Control Panel Administration of the signature. I do not like modifying the core code for Community Server; it makes it a pain to handle updates. So what I did was create a new page to handle the setting of the extended attribute, with the codebehind residing in my CarKnee Bundle. The result is a simple page to create/edit the signature text used for your blog. I should also mention that I dislike having to edit language xml files for basic text. Again, this is just a pain for installing quick modules, but if you are using any language other than English you will have to manually edit the aspx file.
Create your signature:
And here it is:
To install this, download the CarKnee Bundle and follow the instructions in the readme.txt file.
