google maps kml

Question

i am generating a kml out of the posts created by users... but it may so happen that for a new user the kml will be empty... in this case the map does not show. any fixes for this?

Answer 1

You can check the KML with an XML-Parser (e.g. with PHP simplexml_load_file), if there are any Placemarks/Polygons - and only load the map if there's at least one.

Alternatively you could check the database instead of the KML (if one can check there).
