Plugins for WordPress can be very elaborate and require significant programming expertise to develop. But learning to develop a WordPress plugin doesn't have to be difficult; you can start small and grow your skills over time. Let's start with a very simple WordPress plugin that you might build for yourself or a client.

Start by naming your plugin. TIP: When you name your files and directories we recommend you always use lowercase and dashes, never proper case nor underscores. So please don't name your plugin files ThanksForReading. So far so good. A plugin header is a simple PHP comment at the top of the file that minimally only needs the text Plugin Name: followed by the name of your plugin that you want end users to see:.

And that's all the function needs to do. To address these conflicts be sure to prefix your function names. You'll want something hopefully unique and not likely to conflict with function names other plugins or themes might use.

We'll use tfr which is an initialism for "Thanks for Reading":. There are other tutorials on the web about writing WordPress plugins which cover ground that this post does not:. We're not necessarily endorsing all the techniques in those tutorials since we've not read each of them in-depth, we're just telling you they exist. Caveat emptor. As you can see writing a WordPress plugin can be really simple.

This example was deliberately trivial and ignored many aspects of WordPress plugin development but you've got to start somewhere. We have future plans to write in detail about all the aspects of WordPress plugin development that this post ignored.

If you'd like to learn more about writing WordPress plugins you you might want to read this post too:. This is a great tutorial to show the beginnigns of WordPress plugin development, and a good intro to hooks and filters. Thanks, looking forward to more great tutorials like this one.

Thanks for the positive comments. Glad I could help! Please do check out the other posts because this post was just the starting point for how to code a plugin.

Plan to post a lot more all about plugin development over the coming year as well. Quick question — looking at the code for The Complete Plugin, do you need to have a closing? Thanks for the tutorial! Plugin development is something I've been trying to learn, but this is the first tutorial I read that didn't assume I know things like the distinction between "actions" and "filters". It helped. Great question. Nice to read your blog. Thanks for stopping by. Good luck, and be sure to read the follow up posts here as your skills improve because this post is just the tip of the iceberg.

Thanks for the great tutorial! Very simple and easy to follow so I can finally code my first WordPress plugin. I always thought it would be more complicated than this, thanks for putting the time into this easy-to-follow article. Thanks for the comment. Yes, it really can be that easy. But after you get comfortable with that be sure to read the follow up posts in coding techniques that can evolve your plugins from simple to robust, and each post we write is designed to cover just one technique so they come in bite-size pieces.

Thank you for the post; great article, very useful. I need something more for plugin development…. Thanks for the kind comment, and for noticing the style we have chosen for this site. Hello Sir, Nice and simple tutor, even very useful for professional php developers too.. You bring up an broad yet interesting question: how to get values from or put value to the database. When I do this tutorial, I get extra characters on the screen output end of the PHP code rendered on-screen.
