AFCA Pro Hit Tracker

A lightweight WordPress plugin that tracks unique daily hits per post or page via the REST API, with built-in spam and bot protection.

• Author: André Amorim — andreamorim.site
• Version: 1.1
• Requires WordPress: 6.0+
• Requires PHP: 8.1+

Features

• REST API–based tracking — hits are recorded asynchronously via a secure POST /wp-json/pht/v1/track endpoint; no page-reload required.
• Unique daily hits — each IP address can only register one hit per post per calendar day, preventing repeat inflation.
• Bot & spam protection — common crawlers, scrapers and headless clients are detected by User-Agent and silently ignored.
• Rate limiting — each IP is limited to 60 requests per hour per endpoint/post combination; excess requests return 429.
• Origin validation — the tracking endpoint rejects requests whose Origin or Referer header does not match the site's own domain.
• Honeypot field — a hidden hp parameter in the request body silently discards bot-submitted forms.
• Session-level deduplication — the frontend JS stores a sessionStorage flag after a successful track, so navigating back to the same post in the same tab never fires a second request.
• Nonce-secured endpoint — the tracker fetches a fresh wp_rest nonce from GET /wp-json/pht/v1/nonce before every tracking call; invalid nonces are rejected with 403.
• Cloudflare-aware IP detection — real visitor IPs are read from HTTP_CF_CONNECTING_IP when present, so rate limits work correctly behind Cloudflare.
• Dashboard widget — an "Top Posts by Hits" widget appears on the WordPress admin dashboard, listing the five most-viewed pieces of content.
• Admin list columns — a sortable "Hits" column is added to the post/page list tables for all tracked post types.
• Configurable post types — track any combination of public post types from the settings page; defaults to post and page.
• Data reset — the settings page includes a "Reset All Hits" action that wipes all post_hits meta rows and rate-limit transients.
• Self-hosted auto-updates — the plugin checks for new versions daily against the author's own update hub and integrates with the standard WordPress update flow.

Installation

1. Upload the afca-pro-hit-tracker folder to /wp-content/plugins/.
2. Activate the plugin through Plugins → Installed Plugins.
3. Go to Settings → Pro Hit Tracker to configure which post types to track.

Note: The vendor/ directory (Composer autoloader) must be present. If you are installing from source, run composer install first.

How It Works

Browser loads singular post/page
  └─ tracker.js is enqueued (only on singular views for tracked post types)
       └─ Fetches GET /wp-json/pht/v1/nonce  →  receives { nonce }
            └─ POSTs to /wp-json/pht/v1/track with X-WP-Nonce header
                 ├─ SpamGuard checks: bot UA, rate limit, origin/referer
                 ├─ HitRecorder checks: already counted today? (transient)
                 └─ Records hit:
                      ├─ post_hits            (post meta — all-time total)
                      └─ post_hits_daily_YYYY-MM-DD  (post meta — daily bucket)

Hit data is stored entirely in standard WordPress post meta — no custom database tables are created.

REST API Endpoints

GET /wp-json/pht/v1/nonce

Returns a short-lived wp_rest nonce for use in the tracking request.

Response:

{ "nonce": "abc123def4" }

LiteSpeed Cache no-cache headers are set automatically on this endpoint.

POST /wp-json/pht/v1/track

Records a hit for a given post.

Headers:

Body:

Responses:

Post Meta Keys

You can query these directly with standard WordPress functions:

$total_hits = (int) get_post_meta( $post_id, 'post_hits', true );
$hits_today = (int) get_post_meta( $post_id, 'post_hits_daily_' . date( 'Y-m-d' ), true );

Settings

Navigate to Settings → Pro Hit Tracker in the WordPress admin.

Reset All Hits

The Danger Zone section provides a "Reset All Hits" button. Clicking it permanently deletes:

• All post_hits and post_hits_daily_* post meta rows.
• All hit_* deduplication transients.
• All pht_rate_* rate-limit transients.

This action cannot be undone.

Admin Features

Dashboard Widget

A Top Posts by Hits widget appears on the WordPress dashboard home screen, listing the top 5 most-viewed published posts across all tracked post types, with direct edit links. Administrators also see a quick link to the settings page.

Sortable Hits Column

A Hits column is added to the post list table for every tracked post type. The column is sortable — click the header to order posts by total hit count ascending or descending.

Auto-Updates

The plugin registers a daily WP-Cron event (afca_pro_hit_tracker_updates) that polls the author's update hub for new releases. When a newer version is available, it surfaces in the standard Plugins → Updates screen and can be updated with one click.
