I’m working on a WordPress plugin to syndicate my posts to Twitter. I know, there are lots of plugins that does that already but none of the ones I’ve found does it the way I want, so I decided to roll my own. I’ve got the basics working and have been using it on my site for quite some time now. However, I’ve encountered a problem. Here’s how I want it to work:

When I publish a link post, instead of posting a link back to my site to Twitter, it should post the link to the site that I’m linking to. The plugin ”knows” whether it’s a link post or not based on

At first glance this works fine and it worked in development. However, ones I started using it on my site I realized that it only worked some of the times and other times it wouldn’t recognize a link post.

Tonight I’ve managed to narrow it down. It seems like the problem occurs when I post with the ”Press this” bookmarklet. If I do that, even a post that clearly has been givet the ”link” post format still returns false for if ( get_post_format( $ID ) == 'link' ). If I post the exact same content using the WordPress dashboard the post is recognized as a link post and everything else works as intended.

Is this a bug in WordPress? I should investigate this further but right now I need to go to bed, so I’m throwing the question out to you, smart people on the internet, instead.
