[mapserver-users] Draw PHP labels

[Michael McInnis]

Dear mapservers!

My map fails to draw when I attempt to add labels from my labelitem "icao".

Any attempt at using the label objects causes failure. I think I need to create a label object
somehow before I use set() but can't find any examples on line. 

// The following occurs near the bottom of my php code snippet and is commented to allow a successful draw.
$oAirportsClass->label->set("size", 10);

Can someone point me to a working example of drawing labels for a layer?

Thanks






	
	
	
	


// Layer 3 airports--------------------------------------------------------

// Point Symbol
$nSymbolId = ms_newSymbolObj($oMap, "circle");
$oSymbol = $oMap->getsymbolobjectbyid($nSymbolId);
$oSymbol->set("type", MS_SYMBOL_ELLIPSE);
$oSymbol->set("filled", MS_TRUE);
$aPoints[0] = 1;
$aPoints[1] = 1;
$oSymbol->setpoints($aPoints);

// Layer
$oLayerAirports = ms_newLayerObj($oMap);
$oLayerAirports->setConnectionType(MS_POSTGIS);
$oLayerAirports->set("name", "airports");
$oLayerAirports->set("type", MS_LAYER_POINT);
$oLayerAirports->set("status", MS_DEFAULT);
$oLayerAirports->set("labelitem", "icao");
//$oLayerAirports->set("classitem", "MyAirports");
$oLayerAirports->set("connection", "host=xxx port=xxxx dbname=xxxx user=xxxx password=xxxx");
$oLayerAirports->set("data", "geom From (select a.icao, geom From airports a left join airportdata e on a.icao = e.icao where e.icao Is Not Null) as subquery using unique icao using srid=4326"); 

// Class with Labels
$oAirportsClass = ms_newClassObj($oLayerAirports);
$oAirportsClass->set("name","MyAirports");

// Style
$airportsStyle = ms_newStyleObj($oAirportsClass);
$airportsStyle->color->setRGB(255, 22, 22);
$airportsStyle->set("symbolname", "circle");
$airportsStyle->set("size", "3");

//$oAirportsClass->label->set("size", 10);
//$oAirportsClass->label->color->setRGB(0,0,0);
