Is it possible to plot multiple locations on the map?

As of version 1.0.4 it is now possible to render multiple results to the same map.

FAQ #845: “Can I render multiple points to the same map?”.

Solved

Sorry for the delayed response, I've only just started playing with the new version.

Would it be possible to add intelligent zoom similar to the work-around described here: http://www.codedblog.com/2007/09/28/how-to-auto-zoom-and-auto-center-google-maps/

I've made some simple changes to be able to insert javascript that will automatically zoom to contain all points.

 - Only works with map type google
 - Only use with multiple points
 - Rush job so not perfect

See patch here: (for 1.0.4 only)

Example use (after multiple points have been rendered):

$result[0]->renderMap('my_map', array(
                    'mapTypeId' => 'ROADMAP',
                    'zoom' => 8
                ));

$result[1]->renderMap('my_map');

$result[0]->renderAutoZoom('my_map');

I like your implementation. It looks like you have spent some time going over my code and seeing how it works. Your solution is also clean and straightforward. I think I will integrate this into the next release. Thank you.

I'm not sure when the next release will be, though. I have some other projects that I need to focus on, so this one is slightly on the back burner at the moment.

Cheers Brian, I'm glad you liked it. I'll be sure to contribute back any additions i make. I really like what you've created, it's perfect for my needs and easy to add more features and other map drivers.

That's exactly how I tired to design it. I am glad that it is useful to someone else and fulfills the purpose of it's creation.
