What is Custom Post Type Generator?

Use the Custom Post Type Generator to create register_post_type() code with labels, REST visibility, menu settings, rewrite slugs, archive behavior, and supported editor features.

A custom post type is a content model decision. The slug, REST setting, archive choice, and taxonomy relationships should match how editors and templates will use the content.

How to Use Custom Post Type Generator Safely

  1. Name the content type around the real editorial object, such as Portfolio, Event, Property, or Documentation.
  2. Choose a stable slug before launch because changing it later affects URLs and redirects.
  3. Enable show_in_rest if the block editor, API, or headless workflow needs the type.
  4. Place generated code in a small plugin or theme file that is loaded consistently.
  5. Flush permalinks once after registration and test archive, single, admin, and REST behavior.

High-Value Use Cases

  • Creating structured content separate from posts and pages.
  • Adding editor support for thumbnails, excerpts, custom fields, or revisions.
  • Preparing a CPT for block editor or REST API use.
  • Documenting rewrite and archive behavior for SEO review.

Common Mistakes to Avoid

  • Do not change public slugs after indexing without redirects.
  • Do not hide a type from REST if block editor templates depend on it.
  • Do not put business-critical CPT code only in a child theme if content must survive theme changes.
  • Do not register broad generic names that conflict with plugins.

Validation Checklist

  • Save the generated output with the date, target environment, and reviewer.
  • Test the exact page, command, request, or configuration path affected by the change.
  • Check browser console, server logs, PHP logs, database previews, or validators immediately after applying the change.
  • Keep a rollback note so the change can be reversed without guesswork.

Custom Post Type Generator FAQs

Should CPT code go in a plugin or theme?

Use a small plugin when the content type is business data that should survive theme changes. Theme placement is acceptable only for theme-specific presentation content.

Why does my CPT URL show 404?

Flush permalinks after registering the type, confirm the rewrite slug, and check that the registration code loads on every request.

When should show_in_rest be true?

Set it true for block editor support, REST API access, headless builds, and modern editor workflows.

Should I create a CPT or a taxonomy?

Use a CPT for distinct content items with their own fields and templates. Use a taxonomy to classify posts or CPT entries.
