Bart !
That clearifies a lot. I didn't know i could save the mapfile.
The problem was that my new class was the last one in the layer. It
was after:
CLASS
NAME "Other Countries"
EXPRESSION ('[NAME]' ne 'Canada')
METADATA
END
STYLE
ANGLE 360
COLOR 200 200 200
OUTLINECOLOR 100 100 100
SYMBOL 0
END
STYLE
ANGLE 360
COLOR 100 100 100
OUTLINECOLOR 255 255 255
SYMBOL 0
END
END
So i added in php:
$this_layer->moveclassup(2);
Then i changed the expression of the Other Countries Class
$myclass = $this_layer->getClass(2);
$myclass->setExpression("(('[NAME]' ne 'Canada') AND ('[NAME]' ne
'Chad'))");
That was it. Thanks a lot !

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,
you can best use a style object. Example:
$oClass = ms_newClassObj($oLayer);
$oStyle = ms_newStyleObj($oClass);
$aColor[0] = 0;
$aColor[1] = 0;
$aColor[2] = 0;
if ($HTTP_FORM_VARS["COLOR"]!= "")
$aColor = explode(",", $HTTP_FORM_VARS["COLOR"]);
$oStyle->color->setRGB($aColor[0], $aColor[1], $aColor[2]);
Best regards,
Bart

Hi Murat !
No this doesnt solve the problem:
PHP Fatal error: Call to a member function on a non-object in /var/
www/html/mapdemo/bulgaria/test.php on line 13
color is not an attribute of the class object.. Maybe i should try to
define a new layer with php for each country that i would like to
paint..
Thanks for your suggestion !

$new_class->setExpression('Australia');
$new_class->set('name','Australia');
$new_class->color->setRGB(255,0,0);////////////////here you

Hi,
I want to show countries in my world map based on a form with
checkboxes.
If I check Argentina and Australia i would like to show both
countries in red, whereas the other are in another color. If i
change the selection in Australia and India i would like Australia
and India to be red.
I have a .map file with a layer called countries. In that layer i
have a class:
CLASS # Start of CLASS object
NAME 'Argentina'
EXPRESSION 'Argentina'
OUTLINECOLOR 100 100 100
COLOR 255 255 150
LABEL
SIZE LARGE
OUTLINECOLOR 255 255 255
MINFEATURESIZE 40
END
END # End of CLASS object
So i thought if Australia is checked, i add a class object to my
layer using php with the same colors:
$new_class = ms_newClassObj($this_layer);
$new_class->setExpression('Australia');
$new_class->set('name','Australia');
$new_class->label->outlinecolor->setRGB(255,255,255);
$new_class->label->set(minfeaturesize,40);
Australia will not be red however. I do not understand how i can
change the color of my new class. I succeeded only to change the
color of the label.. What do i do wrong ?
If i change the color of an existing class i can see that change
however..
$my_class = $this_layer->getClass(0);
$my_class->setExpression('Australia');
$my_class->set('name','Australia');
Any help will be appreciated !!
Arie
