原文外掛簡介
Creotec Content Expiration Manager adds simple content lifecycle management to WordPress:
Add an expiration date/time to posts, pages, and public custom post types.
Choose what happens when content expires:
Change status to Draft
Make Private/Password Protect (unpublish)
Redirect to another URL (301 or 302)
Replace content with a custom “expired” message
Display an “Expired” banner at the top of the post
Move content to the bin/trash
Optional pre-expiration reminder email to the site admin address.
Reliable processing:
Runs on WP-Cron every 10 minutes
Includes a lightweight fallback check on normal WordPress requests (throttled)
Admin overview page:
Expiring Soon (next 30 days)
Already Expired
Bulk actions (extend date, disable expiration)
Reusable templates for redirect, banner, and replacement-content actions.
Per-post-type enabling/disabling under Settings > Post Expiration.
List-table indicator icons show which posts have expiration enabled.
No external services, no analytics, no licensing system.
Usage
Edit any supported post type.
In the “Expiration” box:
Check “Enable expiration”.
Set an “Expiration date & time” (site timezone).
Optionally choose a reminder email (1/3/7 days before).
Choose what happens when it expires.
Update/publish the post.
To manage expirations site-wide:
* Go to WP Admin > Expirations
* Use tabs:
* Expiring Soon (next 30 days)
* Already Expired
* Use bulk actions:
* Extend by 7 days
* Extend by 30 days
* Disable expiration
To choose which post types support expiration:
* Go to Settings > Expirations.
To create reusable expiration templates:
* Go to Settings > Expirations.
* Create templates for redirects, banners, or replacement content.
* When editing a post, choose a template in the relevant expiration action. Template edits are reflected anywhere that template is selected.
Restore original content (Replace action)
When the action is “Replace content with a message”, the plugin saves the original content when the expiration is processed.
After that, a “Restore original content” button appears in the Expiration meta box, allowing you to restore the saved content and disable expiration for that item.
Expiration processing & reliability
This plugin does not rely solely on WP-Cron.
Primary: WP-Cron runs every 10 minutes to process reminders and expirations.
Fallback: A lightweight check runs on WordPress requests (throttled via transient) to ensure expirations still trigger even if cron is delayed.
Notes about caching:
* Some full-page caches may serve pages without executing PHP. In those cases, expirations will still process when WordPress runs (admin requests, REST requests, cron, etc.).
* On expiration, the plugin triggers an action hook so caching plugins/site code can purge caches:
do_action( ‘creocem_post_expired’, $post_id, $action );
Hooks
creocem_post_expired – Fires after a post is processed as expired.
Parameters: (int) $post_id, (string) $action
