Get it All

I’ve just completed a new plugin, called the Titles to Tags plugin, which I’m sorta proud of. Basically, it checks the title of your post against a list of ignorable words, and then adds tags to your post automatically out of those words that did not appear on the ignore list. The idea is to automatically create a list of relevant keyword tags for your posts. The nice thing is: since I’ve learned to adopt the WordPress API, I’ve found that writing plugins often becomes a much less complex process.

For example, in this plugin, I have to add tags to a post. Obviously, I don’t want to create duplicate tags or create them incorrectly. The new tagging schema is quite complex in the database, and I don’t recommend anyone bother trying to create new tags directly. Instead, I used the wp_add_post_tags() function. This function first checks the current list of tags for the ones I want to add, then if none exist, it creates the tag automatically. This kills both birds with a single stone.

Plus, of course, if the underlying structure of WP should change – and we know it will, eventually – the API will either remain the same or be kept as vestigial, so the plugin doesn’t break because a blog owner did the responsible thing and upgraded to the current version. Another major advantage is that WordPress functions often go through rigorous standards testing and benchmarking, so by using API functions, you’re getting your best shot at creating a highly-compatible and optimized plugin.
