label with mapscript

[Pietro Giannini]

Hi Joerg,

try:

	$oMap = ms_newMapObj("your.map");
	// obtain the layer object:
	$oLay = $oMap->getLayerByName("citylabels");
	// obtain a shape object with the fields of a form (in this case they are
named 'X' and 'Y'):
	$oShape = ms_shapeObjFromWkt("POINT(".$_REQUEST['X']."
".$_REQUEST['Y'].")");
	// set the text property of the shape object:
	$oShape->set("text","ciao");
	// add the shape to the layer:
	$oLay->addFeature($oShape);
	// draw the map:
	$oImage = $oMap->draw();
	$mapImage_url = $oImage->saveWebImage();

I tried and it works well.
You can create how many features you want.
Hope it is useful...

ciao
