Custom Fields & Metaboxes Plugins: My Research

CMB2 is a toolkit for developers to easily add custom fields, metaboxes, and forms to WordPress. With CMB2, you can manage extra data for posts, pages, users, comments, and even create custom options pages. It’s flexible and powerful, making it easier to customize WordPress for any project.

CMB2 is a complete rewrite of the original Custom Metaboxes and Fields plugin. To get started, check the example code included with the plugin and follow the basic usage instructions.

Secure Custom Fields (SCF) makes it easy to add and manage custom fields in WordPress, turning your site into a flexible content management tool. You can quickly create fields for posts, pages, users, and more, and display them in your templates. SCF also lets you register new post types and taxonomies from its interface, giving you more control without extra plugins or code. The plugin is user-friendly and fits right into the WordPress design. Note: Installing SCF will disable similar plugins, such as Advanced Custom Fields, to prevent conflicts.
