Custom Fields in WordPress is a built-in feature that allows users to add additional metadata to posts, pages, and other content types on a WordPress site. It is also known as post meta or custom meta fields. Custom Fields can be used to add extra information to a post or page, such as author information, tags, custom descriptions, and more. This information can then be used in a variety of ways, such as to filter, sort, and display content on the front end of a WordPress site.
Custom Fields can be added to a post or page by using the “Custom Fields” option in the WordPress editor. Users can create their own custom fields with a unique name, and then assign a value to it. For example, a custom field could be created for a post author’s name, with the value being the name of the author.
Custom Fields can be displayed on a WordPress site using various methods, such as by using a plugin or by adding code to the site’s template files. They can be used to display information on the front-end of a site, such as in a post or page’s header, footer, or sidebar, or in a custom loop. Custom Fields can also be used to create custom post types, which are used to create and display content in a specific format, such as for products, events, or portfolios.
Overall, Custom Fields is a powerful feature in WordPress that allows users to extend the functionality of their site and add more customized content and metadata to their posts and pages.
