Itinerary Map Custom Field plugin for Joomla 3.7+ Documentation

Requirement: Joomla 3.7+ | Download


This plugin is a new type of plugin extension for Joomla introduced in the 3.7 version: Custom Fields.


This plugin installs via the usual Joomla installer. Go to your Joomla backend at, login and go to:


Click the browse button to select the archive on your computer.

Click Upload


Once the plugin is uploaded, it installs automatically. You now have to check its global settings. Go to:

TOP MENU > EXTENSIONS > PLUGINS, filter the list by plugin type: FIELDS
And find the GMAP plugin.

As most settings are specific to fields objects, the plugin's global settings are very limited. Only 2 of these:

Google Maps API Key: This is the required key provided by Google so they know how much you use their service so they can check your quota. To get your API Key, go to the Google console API at

Create a project and visit the LIBRARY page. Include these Libraries:
  • Mandatory: Google Maps JavaScript API: Required to render the map used to set a location, clicking on the map overlay and / or dragging markers
  • Mandatory: Google Places API Web Service: Required to be able to move the locator map to specific addresses
  • Optional: Elevation Maps API 
Once the libraries are added to your console project, you can go to the CREDENTIALS page and get your key. It is recommended you set http referrer restrictions to your key so your API key can only be used to your own domain(s).

Input the credentials API key to the relative field in our plugin setting.


Now the plugin is set and ready, we can create our first field. Custom Fields are supported by at least 3 components in the Joomla core: com_content (articles), com_users & com_contacts. Choose one of these for your first ITIN Field. Go either to:

TOP MENU > CONTENT > FIELDS (for fields to show in Joomla Articles)
TOP MENU > COMPONENTS > CONTACT > FIELDS (for fields to show in a contact page)
TOP MENU > USERS > FIELDS (for fields to show in Joomla User profiles)
