Meta Box – A Framework for Dynamic Websites

What the author says it does

You want to add events, team members, testimonials, or listings to your WordPress site. But the standard editor only handles posts and pages. You need something more, but you don’t want to overcomplicate things or slow down your site.

Meta Box gives you everything you need to build dynamic WordPress sites – with over 40+ field types for adding custom fields to posts, pages, custom post types, taxonomies, settings pages, users, and comments. It’s lightweight (no bloat), flexible (works with any theme or plugin), and fast (uses native WordPress storage). No lock-in, no extra baggage.

Any type of custom fields, anywhere

Add custom fields to any part of WordPress:

• Posts & Pages – Add extra fields to regular content
• Custom post types – Use with our free CPT UI plugin to create custom post types and taxonomies
• Taxonomies – Categories, tags, and custom taxonomies via MB Term Meta
• Settings pages – Theme/plugin options via MB Settings Page
• Users – Profile fields via MB User Meta
• Comments – Comment fields via MB Comment Meta

40+ field types (and you can add your own)

Meta Box ships with 40+ built-in field types: text, textarea, WYSIWYG, image, file upload, post select, checkbox, radio, date/time picker, taxonomy, user, oEmbed, and more. You can also create custom field types. Most fields support cloning and repeatable groups.

• Fix stored XSS in background field via unexpected array keys
• Sanitize block editor field content on save

• Public posts and terms stay readable. Password-protected posts need read_post until the visitor enters the password
• User meta needs edit_user
• Use rwmb_meta_shortcode_permission to override the check when needed
