DeveloperShare draft posts with anyone via a secure, time-limited preview link — no login required.
Secure Draft Preview Links lets you generate a cryptographically secure, unguessable link for any draft post so that people without a WordPress account can read it before it goes live.
How it works
- Open any draft post or page in the editor.
- Check Enable public preview in the Publish panel (Classic Editor) or Status & Visibility panel (Block Editor).
- Copy the generated link and share it with anyone.
- The recipient can view the draft without logging in.
- Uncheck the box or set the expiry to Expired to revoke access immediately.
Editor features
- Works with both the Classic Editor and the Block Editor (Gutenberg).
- Checkbox to enable / disable preview — shown even on auto-draft posts (disabled with a “save first” hint).
- When a post is published the checkbox automatically disables and shows “Not available for published posts”.
- Preview URL displayed in a monospace code box — horizontally scrollable, click to select all.
- Copy button and Open preview button inline with the URL box.
- Generate new link button — invalidates the old link immediately, with a confirmation step before firing.
- Stop sharing confirmation bar — shown when unchecking the checkbox, requires explicit confirmation before removing the link.
- Expiry selector with four options:
- 48 hours — default, shows exact time remaining (e.g. “Expires on: Apr 29 · 14:32 (4h 12m remaining)”).
- Always available — link never expires.
- Custom time — set Days, Hours, and Minutes; live “Expires on:” display updates as you type; shows error if all fields are cleared without saving.
- Expired (disable now) — immediately invalidates the link without deleting the token.
- Expiry settings auto-save on change with a “Expiry setting saved.” confirmation message.
- Block Editor: snackbar notices for every action (enable, disable, copy, generate new link).
- Block Editor: Open public preview item added to the Preview dropdown (WordPress 6.7+).
Preview Links admin page
- Dedicated Preview Links menu item in the WordPress admin sidebar.
- Two tabs: Active and Expired, each showing a count badge.
- Paginated table — 20 items per page, with top and bottom pagination controls.
- Per-row columns: Post title, Post type, Exact expiry time, Preview URL, Share buttons, Actions.
- Copy URL and Open preview icon buttons inline with the URL.
- Share buttons: Facebook, X (Twitter), LinkedIn, Email — captions include the post title and expiry time (omitted for never-expires links).
- Regenerate button — generates a new token with a confirmation dialog; old link stops working immediately.
- Stop Sharing button — removes the token with a confirmation dialog.
- Edit Post link opens in a new tab.
- Confirmation dialogs use an inline modal (no browser
confirm()) with clear messaging about consequences. - Toast notifications slide up from the bottom-right on every action.
Security
- Tokens are 64-character cryptographically random hex strings generated with
random_bytes(). - Token validation uses
hash_equals()to prevent timing attacks. - Expired links return a 410 Gone HTTP response.
- Invalid tokens return a 403 Forbidden HTTP response.
- Preview link is automatically removed when a post is published, made private, or trashed.
- All AJAX endpoints are protected with nonces and capability checks.
- No data is exposed to unauthenticated users beyond the post content itself.
Post list table
- Public Preview badge shown next to post titles that have an active preview link.
- Public Preview filter view in the post list table to quickly find all posts with active links.
Technical
- Works with all viewable public post types (posts, pages, and custom post types).
- Pagination links on multi-page posts are rewritten to include the preview token.
- Token meta is registered with the REST API for block editor compatibility.
- No external dependencies — pure PHP, jQuery (Classic Editor), and WordPress’s own React/wp-components (Block Editor).
