Jeremy Upton, DME Supply Group

(updated: 2/18/2015 - fixed for recent Google changes) Shows embedded (map only portion) Google Map within a web viewer object. No API required!

Sample Input:
fnGoogleMap ( 1600 Pennsylvania ; Washington ; DC ; 20500; 12 )
Sample Output:,Washington,DC,20500&z=12&output=svembedmfe&iwloc=0

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


***Recent change*** The last part of the function changed to "&output=svembedmfe&iwloc=0". This fixes the error "The Google Maps Embed API must be used in an iframe." (Thanks, Zorba)

Use this function to define a custom web address within a web viewer object. It will display an embedded map from Google Maps instead of the entire page as with the standard Google Maps output included with Filemaker. There is no need for any Google API.

The last variable "Zoom" sets the default zoom level of the embedded map. It supports values from 1-19. 1 has the least detail with 19 having the most.

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

This fixes the iframe issue in Filemaker 13 for me. Notice the double quotes are changed slightly.

"&output=svembedmfe" & "iwloc=0"

Thanks Tim - I've come back to this and found your answer. This brings up a map, which is great - but it has all the frames with the photos and adverts. I'm too much of an amateur to know how to get rid of these. Can you help?

Still not working. Has there been another change?

I keep getting the google maps overlay (directions etc) on top of the map, and a "sign in" box.

Not exactly what I was looking for. Any ideas?

It is the message from Google "The Google Maps Embed API must be used in an iframe."
