Hi,
If you want to embed a map with multiple markers/locations, first you need to create a map in Google Maps and store it under My places. After creating the map you can embed it in WP using my plugin. You just need to copy the map URL from Google Maps and use it instead of an address in WP. For example:
Map URL:
https://maps.google.com/maps/ms?msid=213303717138000295252.0004ce4da82b563389b91&msa=0
How to embed the map:
{google_map}https://maps.google.com/maps/ms?msid=213303717138000295252.0004ce4da82b563389b91&msa=0{/google_map}
It’s possible to embed maps created in Google Maps Engine too. Before embedding a map please make sure that the map is public and can be viewed by anyone.
{google_map}https://mapsengine.google.com/map/embed?mid=zfQVCQIZMXcw.k_hSHl4b24jM{/google_map}
NB! Only border width, border style, border color, add link, link label and language parameters can be used with maps created in Google Maps Engine. All the other parameters are ignored.
Regards,
Petteri
