Hello, I'm working on a application in wich i have some vector data (a kml file with paths) wich i have to display over a map. I have the data in a database and i can create the kml on-the-fly with a php script, based on some url GET params. I want the create a kml file wich contains only the lines wich are in the current viewport and at a level of detail depending on the zoom level. So, when the user pans the map i shoud update the kml file and display the new data. Same thing when the user zooms the map. My PHP script and kml file are tested and working ok. The problem is how do i code the javascript for this layer. For a similar POI layer i used the instructions from here http://wiki.openstreetmap.org/wiki/OpenLayers_Dynamic_POI and it is ok. But in this case i have no getUrl arg to the constructor. How can be done this ... because i'm sure there is a solution ...
Thank you, Alexandru IOVANOVICI
