Hi !

I have some problems with the drawing of a single point (or two points). =
I have a layer without DATA information in the mapfile.

mapfile
####### home layer #########
LAYER
   NAME "home_point"
   TYPE POINT
   STATUS OFF
   CLASS
      NAME "Ausgangspunkt"
      SYMBOL "s_home"   #in der symbol-datei
   END
END
####### home layer #########

phpfile:

/*********** Layer and the Point to draw ***************/
$home_layer =3D $map->getLayerByName("home_point");
$home_layer->set("status", 1);
$home1 =3D ms_newPointObj();
$home1->setXY($_SESSION["s_fromx"], $_SESSION["s_fromy"]);

if($_SESSION["s_tox"] !=3D 0 && $_SESSION["s_toy"] !=3D 0) {
   $home2 =3D ms_newPointObj();
   $home2->setXY($_SESSION["s_tox"], $_SESSION["s_toy"]);
}

$image =3D $map->draw();   //my map-object
//Home1 und eventuell Home2 dazu zeichnen
$home1->draw($map, $home_layer, $image, 0, "blablabla");
if(is_object($home2) && get_class($home2) =3D=3D "point") {
   $home2->draw($map, $home_layer, $image, 0, "blablabla");
}

Problem:
only the symbol is drawn, not the text. However, I need the text for =
marking of the starting point.
Can this explain anybody to me?=20

Many thanks
Kati
