Custom Post Type Plugin Generator

Start with a clear plugin prompt

Adapt this example to your site, then paste it into your workspace. Include your WordPress, PHP, and relevant plugin versions so the request describes the environment you need to support.

Create a WordPress plugin for a custom post type called Case Studies. Register a hierarchical Industry taxonomy and fields for client name, project URL, completion date, and a featured result. Add a meta box in the editor with nonce verification and sanitization, expose the post type through the REST API, add archive and single rewrite rules, and provide a shortcode that lists the latest case studies filtered by industry.

Model content before writing the prompt

A custom post type works best when it represents a distinct kind of content with its own lifecycle. Start by naming the records people will create, then list the fields editors need and how each field should be validated. Decide whether categories, tags, or a dedicated taxonomy fit the content better. You can also specify the labels, menu location, capabilities, REST visibility, and archive behavior. This gives the plugin a concrete content model instead of leaving important editor and publishing decisions implicit.

Use WordPress registration and editor APIs

A focused custom post type plugin can register post types and taxonomies, add editor meta boxes, use the Settings API for configuration, and expose content through WordPress REST endpoints where appropriate. Describe whether the block editor should support titles, excerpts, thumbnails, revisions, or custom fields. If a public archive or single template behavior matters, state the URL structure and expected output. Keeping the content registration in a plugin means the content remains available when the active theme changes, which supports long-term site maintenance.

Check migration and editorial behavior

Before enabling a custom post type on an established site, test how it fits with existing permalinks, roles, editorial workflows, and plugins. Confirm the new admin menu is understandable, editors can create and update records, and invalid field submissions are handled predictably. Test REST responses if another application consumes the content. After activating the plugin on staging, visit the archive, a single item, and any shortcode output, then refresh rewrite rules through normal WordPress activation handling and verify that existing content remains unaffected.
