heh. I knew you were going to ask me that!
Bascially I want to be able to let people upload an XML GPS data file (.gpx) and then display map of the track data in the post using the Google Maps API.
So all I need to achieve this is the file upload and then to be able to have the filename available in the thread so that I can output something like:
<iframe src="googlemaps.php?file=uploadedfile.gpx"></iframe>
This would save me manually adding the iframe, which is what I am doing atm (
