RP 4U (Maps & Route Planner)

RP 4U (Maps & Route Planner) embeds interactive OpenStreetMap maps (powered by the bundled Leaflet library) into your WordPress site — a privacy-friendly alternative to Google Maps embeds.

Maps without any API key

Create as many maps as you like in the backend (center, marker, zoom, height) and embed each one with a simple shortcode. Plain maps work without any API key or account: addresses you enter in the backend are geocoded once at save time, so the visitor’s browser only loads the OpenStreetMap tiles — nothing else.

Every map with a destination offers a “Navigate here” QR code: visitors scan it and their phone starts the navigation from their current location in Google or Apple Maps.

Optional route planner

Add your own free OpenRouteService API key (see below) and each map can show a full route planner: address autocomplete while typing, route calculation for walking, cycling and driving (recommended / shortest / fastest), a turn-by-turn directions list and a “send route to phone” QR code.

Features

• Unlimited maps, managed in the WordPress backend (custom post type)
• Shortcode embedding: [routenplaner4u id="123"] — multiple maps per page supported
• Fixed destination, pre-filled start, custom center (address or coordinates), zoom and height per map
• Optional route planner per map (checkbox)
• Address autocomplete, turn-by-turn directions with distances and durations
• Map picker: right-click (long-press on touch) uses any point on the map as start or destination — ideal for targets without a street address; picked points get readable names via reverse geocoding
• Colored, numbered pins mark start, stops and destination
• Color settings: adjust the button colors with the WordPress color picker — no CSS needed
• Backend address fields with autocomplete and one-click “use center address” buttons
• QR code / deep links to open the route or destination in Google Maps or Apple Maps (generated locally, no external QR service)
• All libraries (Leaflet, polyline decoder, QR generator) are bundled locally — no CDN calls
• Translation-ready

External Services

This plugin can connect to the following external services. No data is sent anywhere without a map being embedded and used.

OpenStreetMap tile server (always, when a map is shown) The map images (tiles) are loaded from tile.openstreetmap.org in the visitor’s browser. The tile server receives the visitor’s IP address and the map area being viewed. Terms — Privacy

Nominatim geocoding (openstreetmap.org) Addresses entered in the backend are geocoded once at save time (server-side); the backend address autocomplete queries Nominatim while typing. If the route planner is enabled, addresses typed by visitors are geocoded in their browser and points picked on the map are reverse-geocoded to a readable name. Nominatim receives the address text or coordinates and the requesting IP. Usage policy — Privacy

OpenRouteService (openrouteservice.org, only with route planner enabled) Route calculation and address autocomplete use the OpenRouteService API with the API key you configure. The service receives start/destination coordinates, typed address fragments and the requesting IP. Terms — Privacy

Google Maps / Apple Maps deep links (only on user click) The QR codes and “open in…” links point to google.com/maps and maps.apple.com. Nothing is sent to these services unless the visitor actively scans the code or clicks the link.
