Custom Metadata Manager is a plugin that allows developers to add custom fields to posts, pages, custom post types, and users through a straightforward code-based approach. It is designed for site builders and developers who need to extend content management without writing extensive repetitive code. The plugin handles the backend complexity, enabling you to focus on data structure and user interfaces.

Code-based API: Register fields and groups using functions like x_add_metadata_field, similar to how custom post types are set up, ensuring a familiar workflow for developers.

Multiple field types: Supports text, textarea, checkbox, select, upload, wysiwyg, datepicker, and taxonomy fields, providing flexibility for different data input needs.

Group organization: Create metaboxes to group related fields together, improving user interface clarity and organization in the admin area.

Exclude/include controls: Limit fields or groups to specific objects or IDs, allowing for precise customization based on content or user requirements.

Data safety: Stores metadata using standard WordPress APIs, so data remains accessible even if the plugin is deactivated, ensuring no loss of information.
