Overview of this book

WordPress is one of the most widely used, powerful, and open content management systems (CMSs). Whether you're a site owner trying to find the right extension, a developer who wants to contribute to the community, or a website developer working to fulfill a client's needs, learning how to extend WordPress' capabilities will help you to unleash its full potential. This book will help you become familiar with API functions to create secure plugins with easy-to-use administration interfaces. This third edition contains new recipes and up-to-date code samples, including new chapters on creating custom blocks for the block editor and integrating data from external sources. From one chapter to the next, you’ll learn how to create plugins of varying complexity, ranging from a few lines of code to complex extensions that provide intricate new capabilities. You'll start by using the basic mechanisms provided in WordPress to create plugins, followed by recipes covering how to design administration panels, enhance the post editor with custom fields, store custom data, and even create custom blocks. You'll safely incorporate dynamic elements into web pages using scripting languages, learn how to integrate data from external sources, and build new widgets that users will be able to add to WordPress sidebars and widget areas. By the end of this book, you will be able to create WordPress plugins to perform any task you can imagine.

The previous recipe showed how to look up the translation of a text item and return its value for further processing in the plugin code. There are many instances where it is more practical to display the translated content immediately, as we'll see in this recipe.

Getting ready

You should have already followed the Adapting default user settings for translation recipe to have a starting point for this recipe. Alternatively, you can get the resulting code (ch12/ch12-hello-world/ch12-hello-world-v1.php) for that recipe from the book's GitHub page and rename the file to ch12-hello-world.php.

How to do it...

Follow these steps to translate the contents of a simple administration page for immediate display:

  1. Navigate to the ch12-hello-world folder of the WordPress plugins directory of your development installation.
  2. Open the ch12-hello-world.php file in a text editor.
  3. Add the following line of code at the end...
