Solid Post Likes

Solid Post Likes adds a customizable like button to your posts, pages, custom post types, WooCommerce products and comments. Zero configuration required — activate, pick your post types and go.

The same button likes and unlikes. Visitors can like too (stored anonymized), or restrict liking to logged-in users.

Where it shows:

• All post types, selectable per post type.
• Single posts, and optionally archives, search results and query loops.
• WooCommerce products — all product types (Subscriptions, Bookings, …).
• Post comments, also on custom post types.
• Anywhere you want via shortcode.

Block and shortcodes:

• Like Button block — drop it anywhere, including inside Query Loops. Counter toggle in the sidebar.
• [oacsspl] — the like button. Arguments: post_id, counter=off to hide the count for that instance.
• [oacsspltop count=5 post_type=post] — the most-liked posts, with counts. Add days=7 for trending (most likes in the last 7 days).
• [oacsspllist] — the posts the current user likes. Add user_id=123 to show a specific user's likes.
• [oacs_spl_profile] — same list, table style.

Control who likes:

• Visitors can like. Since 1.2.0 visitors are remembered via an anonymous browser cookie (no personal data, works behind shared/mobile networks); before that via anonymized IP — the stored address always ends in .0.
• Or logged-in users only: the button and count stay visible, clicking sends visitors to the login page (or a custom URL).
• One-way likes: optionally disable unliking to prevent accidental removals.

Design:

• 29 icons for the liked and unliked state, individually selectable.
• Custom text for like and unlike.
• Color, size and padding controls for icon, text and counter.

For admins:

• Sortable "Likes" column on the post list of every enabled post type.
• Liked posts shown in the backend user profile.
• Set or reset like counts manually.
• Disable likes per post ID.

For developers:

• REST API: GET /wp-json/spl/v1/likes/<id> and POST /wp-json/spl/v1/likes/<id>/toggle — for headless and mobile use (Application Passwords supported).
• Every like is stored as its own database row with a timestamp (since 1.2.0) — no more lost likes under concurrent clicks, and trending queries become possible.
• Place the button via your own theme hook (posts and WooCommerce separately).
• before_oacs_spl_button / after_oacs_spl_button filters for custom content around the button.
• Full page cache support: like state and counts load via Ajax, including a fresh nonce, so cached pages keep working.
