Shortcode

A shortcode is a small piece of code enclosed in square brackets used in WordPress to embed complex functionality into posts, pages, or widgets without writing PHP or HTML. For example, a contact form plugin might provide a shortcode like [contact-form-7] that you paste into your page to display a form. Shortcodes were widely used before the Gutenberg block editor was introduced. While shortcodes still work in modern WordPress, blocks are now the preferred way to add dynamic content to pages as they integrate more cleanly with the editing interface.
