<div>Hi all,<br></div><div><br></div><div></div><div>I'm still trying to make a dynamic POI, or marker, or points layer, whatever you want to call it, that changes the points in the map in response to user's searches. I can't use mapserver or a pre-programmed server-side option, so I'm forced to write my own gml or wkt. I'm still not quite sure how to get this GML to OL and then replace it by the next search.</div>
<div><br></div>
<div></div>
<div>I think there are two options. One of which would be to send data to a markers layer and have JS write the markers out. The other would be to have php re-write the gml file on the server and theoretically, this should create a new set of points each time the search is submitted. Not sure what the best/easiest option would be with respect to coding (either on the browser or server-side) or from a performance perspective. Does anyone have any recommendations? I'm basically copying a php/mysql kml tutorial and adapting it to GML (for largely ideological reasons). I've just re-read the GML documentation, and it states that the GML is meant to only be loaded once, so should I be focusing on a dynamic marker layer or what?</div>
<div><br></div><div>In effect, all I really want is a simple ajax function to load the POI/markers that correspond to search criteria, such that every search produces a unique (within a limited span of variation of course). The maps centering won't really change, just the make up of the sites displayed in the map. I can write the gml server side, and I can send the request, but I'm not sure what to do with the call-back or how to feed that info to OL. </div>
<div><br></div><div>Thank you in advance for any advice/help.</div><div>(incidentally, I'd be willing to consider contracting someone to do this)</div><div><br></div><div>best,</div><div>Nick</div>
