Hello again,
I'm having problems getting any results with queryByPoint.
Basically I draw my map as usual then I try the following on the drawn
layer:
$my_point = ms_newpointObj();
$my_point->setXY($_REQUEST["mapa_x"],$_REQUEST["mapa_y"]);
$result=$uLayer->queryByPoint ($my_point,MS_SINGLE,-20);
I tried different buffers, zooming in etc. but I always get: "No matching
Record(s) found"
The layer is drawn OK, and is simple as far as the mapfile goes (nothing
apart from):
...
STATUS ON
TYPE POINT
LABELCACHE FALSE
CLASS
SYMBOL
END
END
...
The points are drawn in from a database, so if I could convert the
$_REQUEST clicks into lat/lon I could just query the database instead of
mapserver.
Has anyone got any light to shed on this? I'd be most grateful if someone
could show me what I'm doing wrong, or suggest how to get the lat/long
values. The archives didn't seem to have anyone in my situation - which
suggested to me I'm missing something basic out.
Thanks in advance,
