Folders for the post types you register in code

You registered a post type for the client: case studies, branches, products of a catalog. The client added the hundredth item and asked how to sort them.

Plathix PRO adds private folders to the standard list of your type. No taxonomy to register, no admin screen to build. Your code, URLs and queries stay as they are.

Part of PROTypes with show_uiCode unchanged

Built in code

You registered the type. The client filled it.

A type with show_ui gets the standard WordPress list and nothing more: titles, dates, status tabs, search.

When the list passes a hundred items, the client asks for groups. A private taxonomy means more code, a meta box, a filter dropdown and one more thing to maintain on every site you hand over.

Plathix PRO adds the folders to the list you already have.

functions.php

// your code, unchanged
register_post_type( 'case_study', array(
'label' => 'Case Studies',
'public' => true,
'show_ui' => true, // standard list in wp-admin
) );
// 'case_study' has 10 characters: the limit is 17

In people’s words

Private labels for your own posts

Developers who register their own types ask the same things. The type works on the site. The list in wp-admin has no private place for the team’s groups.

You want to tag posts with private, admin-only terms. The terms should have no URL of their own and should not be searchable on the front end.

The standard list is not much help. Even simple jobs, like grouping posts by your own rules, make people ask whether everyone writes a plugin for it.

The usual workaround is a custom taxonomy that only the backend uses, plus a dropdown filter on the list.

A type collects years of content. Posts from 2018 to 2020 are still in the list and now have to be cleaned out.

Folders give the standard list of your type a private tree, with no taxonomy to register and no filter to build. None of it shows on the site.

Folders your clients will actually use

By industry

Healthcare, retail, finance: sales opens one folder and finds the right case study.

Waiting for approval

Items the client has not signed off yet stay drafts, together in one folder.

After a migration

Imported a few hundred items from the old site? Keep each batch in a folder until someone checks it.

Old work

Older items stay published and move out of the daily list.

Before you delete

Old posts you plan to remove wait in one folder. Check them there first, and keep the ones that still bring visitors.

What you get

What your type needs, and what it gets

Three conditions

show_ui is true, the type keeps the standard edit.php list, and its name has 17 characters or fewer. Then it appears in Settings → General → Enabled Sections.

Its own tree

Each enabled type gets a separate folder tree with its own Folder column. Folder names never mix with Pages, Media or another type.

Your capabilities

Plathix reads rights from your type. Users who can publish its items manage the folders; users who can edit them put items in folders.

REST for scripts

The plathix-pro/v1 namespace has the same folder routes as Plathix Free, with a post_type parameter. Build a tree or file items from a deploy script.

Virtual folders

Your code never sees the folders

What you do	What changes	What stays as it is
Put an item in a folder	Its Plathix folder	Its URL, slug, parent, terms and status
Run your queries on the site	Nothing	They return the same posts as before
Rename or move a folder	The folder tree in wp-admin	Permalinks, rewrite rules and menus
Trash an item, then restore it	Its Trash state	Its folder: it comes back to the same place
Turn Plathix PRO off	The list looks like plain WordPress	Your folders wait in the database and come back

Folders are a private taxonomy: no URLs, no rewrite rules, not in the WordPress REST API.

Evidence

How we test custom post types

We run each check on a live site with Plathix PRO and a post type registered in a small test plugin.

Status Planned

Results go to Plathix Lab. Each row turns into a link once it has run.

Check	What we verify	Status
Enable a code type	A type with show_ui true appears in Enabled Sections; the panel appears on its list.	Planned
Under another menu	A type shown under another plugin’s menu gets the panel on its list.	Planned
Custom capabilities	A user with only this type’s capabilities manages folders and files items.	Planned
REST with post_type	Create a folder and put items in it through plathix-pro/v1.	Planned
Own columns	A type that sets its own columns: where the Folder column appears.	Planned
Trash and restore	A trashed item comes back to its folder.	Planned

Custom post type folders FAQ

Which of my types can get folders?

Types with show_ui set to true, the standard edit.php list and a name of 17 characters or fewer. They do not need to be public.

Why 17 characters?

Each type’s folders live in a private taxonomy named plathix_folder_ plus the type name. WordPress allows 32 characters for a taxonomy name, and the prefix takes 15.

Can a script create folders and file items?

Yes. Use the plathix-pro/v1 REST namespace with a post_type parameter. The same rights apply as in the folder panel.

Who can manage the folders?

Plathix reads your type’s capabilities. Users who can publish its items manage the tree; users who can edit them put items in folders.

Will folders change my queries or URLs?

No. Folders have no URLs and no rewrite rules, and queries on the site return the same posts.

Is this in Plathix Free?

No. Content folders are part of Plathix PRO. Free organizes the Media Library.
