NOTE: feedbackBP has now been updated and has become MCEngine

feedbackBP lets your users leave a comment on each paragraph of post.

It’s great for:

• Leaving corrections and clarifications on any blog
• On a news site or blog you can let your users suggest other areas of interest and investigation.
• Document annotation – each post could be a chapter of a book or document.

Features:

You can control who can leave and who can see comments

• Respects the comment settings of individual posts and comment moderation
• Uses Thickbox for a neat pop-up window for comments
• Hides the paragraph comments from the main comment window so you can have macro and micro comments on a post

This plugin was written to help me feedback comments on blog posts to my journalism students who use wordpress as a base for their online publications.

It was based on an idea I saw at http://newsmixer.com which allows users to comment or ask questions on a particular paragraph. The creators of newsmixer are looking to turn the thing in to an API with a wordpress pluging which would be cool but seems a little way off.

The closest plugin I could find is one called marginalia (http://marginalia.cc/) which looks very nice but doesn’t seem to play well with WordPress 2.8. So I’ve written Feedback by Paragraph to fill the gap.

Why would you want to comment on a paragraph?

One of the basic writing styles that we get Journo students to use is to think about one fact per paragraph. That may sound limiting or over simplistic but it’s a good structural approach. So if you allow people to comment by paragraph they can question, clarify or dispute that bit of content. In a broader (and online) sense this is useful as it makes the feedback more specific and encourages threading off the fact in to broader areas of discussion. A bit like a mental/micro hyperlink.

In its basic form the plugin is really there to allow me to leave feedback on students work. Pointing out good and bad, par by par, is useful feedback. But I hae developed it to be a little more flexible.

How does it work?

FBP does a couple of things:

• It hijacks the content of the post, looking for the </p> tag and inserting a little bit of code that attaches a pop-up box to that paragraph so you can leave comments. It inserts a little bubble with a link to open the box. It only does this on the article page (what WP calls a single post as defined by the template single.php). It uses the closing p tag because it’s the easiest one to find as the <p> is often full of crap like classes etc and my regex is not really up to that. Using </p> also has the advantage of picking up any image captions without breaking the styling class.
• It saves any paragraph comments with a custom ‘comment type’ so that they can be associated with a paragraph *It filters out any paragraph comments from the normal comment display
