Descrizione
Custom Metadata Manager gives developers a single, consistent API for adding custom fields to any object type in WordPress: post, page, any custom post type, user and comment. Rather than offering a point-and-click interface, it follows the WordPress approach of registering content in code, so your fields live alongside the rest of your theme or plugin.
Fields are grouped into metaboxes, stored through the standard WordPress metadata APIs, and remain available even if the plugin is later deactivated. You can render fields with the built-in field types or supply your own display and sanitisation callbacks, and you can include or exclude fields and groups for specific objects, either by ID or through a callback.
This approach is particularly useful when working across multiple environments (local, staging and production), because your field definitions travel with your code and need no database synchronisation.
Usage
Custom Metadata Manager is a developer-focused plugin: you register your fields and groups in code, typically from a theme’s functions.php or your own plugin. The full API reference — object types, registering fields and groups, include and exclude rules, multifields and worked examples — is documented in DEVELOPERS.md.

FAQ
-
Why a code-based approach instead of a UI?
-
Because the UI approach has been done many times before, and a code-based approach aligns more closely with the existing WordPress model for registering content, such as post types and taxonomies.
This is a developer feature aimed at site builders. The main benefit becomes clear when you work across multiple environments (development, staging and production): you can replicate interfaces and features without worrying about database synchronisation.
-
Why isn’t the function just `add_metadata_field`? Why the `x_` prefix?
-
We are namespacing our public functions, and you should too. The
x_prefix keeps the plugin’s functions from clashing with anything else in WordPress core, themes or other plugins. -
How do I use this plugin?
-
See DEVELOPERS.md for full instructions, and the
custom_metadata_examples.phpfile for worked examples.
