Rubik Internal Redirect Updater

Plugin Name: Rubik Internal Redirect Updater

Version: 1.2
Author: Matteo Morreale
Description: This plugin updates internal links on a WordPress site that point to 301 redirects, replacing them with their final target to avoid unnecessary redirect hops and improve performance.

--- WARNING --- The Rubik Link Analyzer plugin must be installed, and a scan must have been performed.

Features

• Internal Link Scanning: Scans site posts to identify internal links pointing to 301 redirects.
• Automatic Updates: Automatically updates links to point directly to the final URL, improving SEO and reducing load times.
• Simple Interface: Provides an admin interface to start scans and view modification logs.
• Status Tracking: Processed links are tracked in a support table to avoid repetitions and infinite loops.

Requirements

• Rubik Link Analyzer plugin with a completed scan.
• WordPress 5.0+
• PHP 7.0+
• cURL enabled for HTTP requests.

Installation

1. Upload the plugin: Upload the plugin folder to the /wp-content/plugins/ directory.
2. Activate the plugin: Go to the WordPress Plugins section and activate "Rubik Internal Redirect Updater."
3. Admin Options: A new menu item called "Redirect Updater" will appear in the WordPress admin panel.

Usage

1. Access the plugin: Navigate to Redirect Updater in the WordPress admin menu.
2. Start the scan: Click the "Start Scan and Update Links" button to begin scanning posts.
3. View modification logs: During the scan, the plugin will display a log of processed links, including:
   • The post title where the link was found (with a link to the post itself).
   • The original URL of the link.
   • The status of the check (e.g., OK, Ignored, Error).
   • The HTTP response code for each link (e.g., 301, 404, etc.).

How It Works

• Link Scanning: The plugin scans links within posts to determine if they point to 301 redirects.
• Redirect Processing: Internal links are updated to their final destination if the redirection is confirmed.
• Comprehensive Log: A log is generated for each operation, including errors and HTTP response codes.
• Processed Link Tracking: To avoid loops and repetitions, processed links are tracked in a separate table (rubik_processed_links).

Tables Used

• rubik_link_data: Existing table used for link scanning.
• rubik_processed_links: Support table created by the plugin to store processed links and prevent repetitions.

Security Notes

• The plugin uses nonces to protect AJAX calls and prevent CSRF attacks.
• Link verification is performed using cURL, ensuring the plugin follows redirects without exposing vulnerabilities.

Limitations

• Currently, the plugin does not modify external links, marking them as ignored in the log.
• If a link undergoes a chain of redirects, the plugin follows all redirects up to a maximum of 10 to avoid potential infinite loops.

Uninstallation

When the plugin is deactivated, the support table (rubik_processed_links) is removed to free up database space.
