A custom update checker for WordPress plugins. Useful if you don't want to host your project in the official WP repository, but would still like it to support automatic updates. Despite the name, it also works with themes.

Background (i.e. unattended) plugin updates require an additional $update->plugin field to be set to plugin file name relative to the /wp-content/plugins directory. Fixed by adding a $filename property to the PluginInfo and PluginUpdate classes and updating toWpFormat() to return it as "plugin". Apparently WordPress update API introduced the field a couple of minor versions back, but I didn't notice because it's used *only* by the background updater and ignored otherwise. I named the internal variable "filename" instead of "plugin" because "plugin" is very vague. It doesn't really tell you if the variable contains a plugin slug, plugin name, the full plugin filename, a partial filename, basename or something else. "filename" is a bit less ambiguous, though not perfect. Bumped version to 1.6. |

Plugin Update Checker
This is a custom update checker library for WordPress plugins. It lets you add automatic update notifications and one-click upgrades to your commercial and private plugins. All you need to do is put your plugin details in a JSON file, place the file on your server, and pass the URL to the library. The library periodically checks the URL to see if there's a new version available and displays an update notification to the user if necessary.
From the users' perspective, it works just like with plugins hosted on WordPress.org. The update checker uses the default plugin upgrade UI that will already be familiar to most WordPress users.
