Snippets Included

1. LearnDash Nested URL Mapper

A highly technical script to fix 404 errors for nested lessons, topics, and quizzes. It is Polylang-aware and handles access validation.

• File: wp-learndash-nested-url-mapper.php
• Features: Strict CPT validation, redirect guard to prevent ping-pong loops, and stable gate URLs for unauthorized users.

Installation Guide

Method 1: functions.php (Child Theme)

Copy the code (excluding the opening <?php tag) and paste it at the bottom of your child theme's functions.php.

Method 2: Code Snippets Plugin (Recommended)

Add a new snippet, paste the code, and set it to run where appropriate. Note: Check if your plugin automatically adds <?php; if so, omit it from your paste.

Method 3: MU-Plugin (Best for Performance)

Create a new .php file in wp-content/mu-plugins/ and paste the code. Note: You must include the opening <?php tag at the very top for the code to execute.

Recommendation: For routing scripts like this, using an MU-Plugin is the most robust method as it ensures the code is always active regardless of theme changes.
