[mapserver-users] php-mapscript problem and symbolname trying to open a file?

[Ben Madin]

Thanks Thomas,

you are correct - I was actually not specifying any symbol set at all :

For reasons I can't begin to work out, most of the map file is being written, but the symbol and font lines are failing :

  $blumap=new MapObj('',$mapserver_path);
	$blumap->set('debug','MS_ON');
	$blumap->setprojection('proj=latlong,ellps=WGS84,datum=WGS84',MS_TRUE);
	$blumap->set('units',MS_DD);
	$blumap->imagecolor->setRGB($sea_bgc[0],$sea_bgc[1],$sea_bgc[2]);
	$blumap->setExtent(110, -45, 160, -10);
	$blumap->setSymbolSet('/usr/local/www/apache22/data/nahis/mapserver/symbols/standard.symbols');
	$blumap->setFontSet($mapserver_path.'fonts/standard.fonts');
	$blumap->outputformat->set('name', 'png');
	$blumap->outputformat->set('driver', 'agg/png');

…

is giving me :

MAP
  EXTENT 110 -45 160 -10
  IMAGECOLOR 230 252 255
  IMAGETYPE "png"
  NAME "MS"
  SIZE 600 600
  STATUS ON
  UNITS DD

  OUTPUTFORMAT
    NAME "png"
    MIMETYPE "image/png"
    DRIVER "agg/png"



…


Why might the setsymbol and setfont lines be failing to produce mapfile output - but the rest are working fine? Noting that the path in the command is used in other static map files and is working when it is in the file.

If I copy and paste this path into the map file generated by PHP, I get my desired result… 

cheers

Ben
