WordPress Shortcode API

The WordPress Shortcode API allows you to create custom macros (shortcodes) that can be used in posts and pages. Here's a brief explanation of each step:

1. Register the Shortcode: Use the add_shortcode function to register a shortcode and specify the callback function that will be called when the shortcode is used.

2. Define the Callback Function: Create a function that will be executed when the registered shortcode is used in a post or page. This function should return the content that will replace the shortcode in the post or page.

3. Use the Shortcode: In your WordPress posts or pages, you can use the registered shortcode by typing the shortcode name in square brackets, like this: [my_shortcode].

4. Processing the Shortcode: When WordPress encounters the shortcode in a post or page, it will call the callback function you defined and replace the shortcode with the content returned by the function.

By following these steps, you can create and use custom shortcodes to add dynamic content or functionality to your WordPress site.
