[mapserver-users] ms_newLayerObj (fwd)

[Assefa Yewondwossen]

Hi There,

 I just tested the creation of layers dynamically using php/mapscript and It seems to
work fine.

 From the code bellow I think the only problem in your case is the way you define the
colors. You should do soemthing like this :
....
$newclass = ms_newClassObj($newlay);
$colorId = $map->addColor(0, 0, 255);
$newclass->set("outlinecolor", $colorId);
...

I am assumoing here that all the seeting of the other parameters (like data, ...) are
correct.

Hope it helps,

Later,
