Re: [UMN_MAPSERVER-USERS] problem plotting points on map using PHP/MapServer

[Ben Madin]

G'day Ben, I'm still working through this myself, but some thoughts below. there is a very helpful powerpoint called php_mapscript_mum2.ppt from DMSolutions, google it and get it.  Also, bookmark http://www.maptools.org/php_mapscript/index.phtml?page=phpmapscript-class-guide.html if you haven't already. So far, I can draw the basic map with a country outline. However, I am unable to draw points on the map. I have set up the basic map, and added a class and a layer for the points. I then run the following code: $image=$map->draw(); $point = ms_newPointObj(); $point->setXY(-21.97, 64.15); $return = $point->draw($map, $pointsLayer, $image, 0, 'A beautiful point'); $return is 0.  Is there any way I can get further information as to what might be going wrong here, with more detail than just the success/failure methods? I might have this wrong, but you seem to have to turn your pointObj into a lineObj to add it to a shapeObj to add to the map. This is how I do it : (the str_replace is to deal with , decimals) $outbreakshape = ms_newShapeObj(MS_SHAPE_POINT); #B now add the points... foreach($dispmappoint->itemlist as $ob_id=>$locn) { #B make a point $outpoint = ms_newPointObj(); $outpoint -> setXY($locn[1],$locn[0]); #B Add it to a line object $obline = ms_newLineObj(); $obline->add($outpoint); #B Add it to our shape $outbreakshape->add($obline); } $dislayer->addFeature($outbreakshape); #B then add the feature to the map. Now try drawing it. Apparently the PHP function ms_newMapObj() must have a map file passed to it, although I noticed that the Python version does not. Is there a reason for this? At the moment, I have a dummy map file containing nothing which I have to use. No, it doesn't need one (or it didn't @ 4.8) you can just use $map=ms_newMapObj('',$mapserver_path); If I use something like $layer->name = 'Layername', the layer name is not set (in fact it is set to null). Using $layer->set('name', 'Layername') it seems fine. Not really a problem, just wondered why. Others could answer this I'm sure... but although it seems a bit annoying at first, it is great for reusing code. I guess they have one function in the class that sets any variable. Good luck, and if I have it wrong, I'd be delighted to be corrected, or to see some smarter code. cheers Ben --  Ben Madin REMOTE INFORMATION t : +61 8 9192 5455 f : +61 8 9192 5535 m : 0448 887 220 Broome   WA   6725 [EMAIL PROTECTED] Out here, it pays to know...
