How to Add Google Maps with Multiple Locations to Your Joomla 4 Website (Complete Guide)

Adding an interactive map with multiple locations to your Joomla 4 site can enhance user experience for businesses with multiple branches, event organizers, or travel websites. While Joomla offers extensions for this purpose, the setup process involves several technical steps. This guide covers both extension-based and manual coding approaches.

Method 1: Using Joomla Extensions (The Most Common Approach)

Step 1: Choosing and Installing a Maps Extension

Joomla has several map extensions, but many are outdated or not compatible with Joomla 4. Here are the current options:

  • 1. Log in to your Joomla 4 Administrator panel
  • 2. Navigate to System → Install → Extensions
  • 3. Search for map extensions. Popular options include:
    •    – Google Maps v3 (by NoNumber) – Simple but limited
    •    – Maply – More advanced features
    •    – GMapFP – For multiple locations

Step 2: Configuring Google Maps API Key (Critical Step)

This is where most users get stuck. Since June 2018, all Google Maps implementations require an API key with billing enabled.

  • 1. Create a Google Cloud Project:
    •    – Go to [Google Cloud Console](https://console.cloud.google.com/)
    •    – Create a new project
    •    – Enable billing (yes, credit card required, but you get $200 monthly credit)
  • 2. Enable Required APIs:
    •    – Maps JavaScript API
    •    – Geocoding API (for address conversion)
  • 3. Create and Restrict API Key:
    • javascript
// Example of restricted API key settings
// Restrict to your domain only for security
HTTP referrers: yourdomain.com/*
APIs: Maps JavaScript API, Geocoding APICode language: JavaScript (javascript)

Step 3: Configuring Your Chosen Extension

Let’s use Google Maps v3 (by NoNumber) as an example

  • 1. Install and enable the plugin
  • 2. Go to Plugins → Search for “Google Maps”
  • 3. Enter your API key in the plugin parameters:
  • 4. Syntax for adding multiple locations in an article:
    • html
{googlemaps width=100% height=400 zoom=12}
Address 1: Your first location details|Marker Title 1
Address 2: Your second location details|Marker Title 2
Address 3: Your third location details|Marker Title 3
{/googlemaps}

Step 4: Limitations of Joomla Map Extensions

Despite their convenience, Joomla map extensions often suffer from:

  • 1. Outdated Code: Many haven’t been updated for Joomla 4
  • 2. Limited Customization: Fixed marker styles, limited controls
  • 3. Performance Issues: Can slow down page loading
  • 4. Mobile Responsiveness Problems: Don’t always adapt well to different screens
  • 5. Complex Updates: Changing locations often requires editing article code

Method 2: Manual Implementation with Custom Module

For more control, you can create a custom module with your own HTML/JavaScript.

Step 1: Create a Custom HTML Module

  • 1. Go to Content → Site Modules → New
  • 2. Select Custom as the module type
  • 3. Set your module position and assignment

Step 2: Add the HTML/JavaScript Code

In the module editor, switch to the HTML view and add:

html

<div id="map-container-joomla" style="width: 100%; height: 500px;"></div>

<script>
// Wait for the document and Google Maps to load
function initMap() {
    // Define locations array
    const locations = [
        {lat: 40.7128, lng: -74.0060, title: "New York Office"},
        {lat: 34.0522, lng: -118.2437, title: "LA Branch"},
        {lat: 41.8781, lng: -87.6298, title: "Chicago Warehouse"}
    ];
    
    // Create map centered on first location
    const map = new google.maps.Map(document.getElementById('map-container-joomla'), {
        zoom: 4,
        center: locations[0]
    });
    
    // Add markers for each location
    locations.forEach(location => {
        new google.maps.Marker({
            position: location,
            map: map,
            title: location.title
        });
    });
}
</script>

<!-- Load Google Maps with YOUR_API_KEY -->
<script async defer 
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY_HERE&callback=initMap">
</script>
Code language: HTML, XML (xml)

Step 3: Addressing Common Issues

  • Problem: Map doesn’t load or shows API error
    • Solution: Check your API key restrictions and ensure billing is enabled
  • Problem: Map breaks Joomla template
    • Solution: Add CSS to module:
      • css
#map-container-joomla img { max-width: none !important; }
.gm-style { font-family: inherit !important; }Code language: CSS (css)
  • Problem: Map doesn’t appear on mobile
    • Solution: Add responsive CSS:
    • css
@media (max-width: 768px) {
    #map-container-joomla { height: 300px !important; }
}
Code language: CSS (css)
