Greetings Library Scientist

The California Library Association is pretty much like every other regional library association I’ve seen, not least because their most visible presence is their annual conference.

Improving Will Norris’ Open Graph Plugin

Will Norris put together a nice WordPress plugin to place Open Graph metadata on the page. Today I patched it to address a few bugs I and others have found.

The patch switches functions that depended on globalizing $post to use $wp_query->queried_object and similar.

opengraph_default_url() is changed to try get_permalink() only when is_singlular() is true. Otherwise it uses the blog’s base URL. This isn’t perfect, but it’s better than having the front page and all tag/category/archive pages report their og:url as being the permalink for the first post on the page.

As suggested here, I changed the opengraph_default_description() to use the post’s excerpt if is_singular() and the post includes an excerpt.

I changed opengraph_default_image() to test if the theme supports post thumbnails before calling has_post_thumbnail() to avoid the Fatal error: Call to undefined function has_post_thumbnail() errors.

I submitted it as a bug report in the plugins Trac, but I don’t check there for tickets on my own plugins, so you might apply the patch yourself.
