Mapscript adding class with PHP

[Eijnden, Bart van den (AGI)]

Arie,

can you save your MAP using 

$map->save('<filename>');

?

And post the output LAYER definition?

Also, have you set CLASSITEM on your LAYER?

Best regards,
Bart

Bart !

My code is now:

$this_layer = $map->getLayerByName('countries');

$new_class = ms_newClassObj($this_layer);

$new_class->setExpression('Russia');
$new_class->set('name','Russia');
$new_class->label->outlinecolor->setRGB(255,255,255);
$new_class->label->set(minfeaturesize,40);
$new_style = ms_newStyleObj($new_class);
$new_style->color->setRGB(100,100,100);
$new_style->outlinecolor->setRGB(255,255,255);

$img=$map->draw();

$img->saveImage("/var/www/html/mapdemo/images/test.jpg");

Doesnt work however..

I really appreciate your help !

Arie
