Solution: RE: [UMN_MAPSERVER-USERS] Layer working in mapfile, not (fully) working within PHP

[Hoeven, Maarten van der]

I found the solution for my problem; this to inform the list (and other
with an alike problem).

The code is okay, I had to add the following to get the labels displayed
on the map

$layerObj1->set("labelcache",MS_OFF);

That's all :)

Hi list,

thanks for all your help; all suggestions are most useful!

My problem is, when I use the layer-definition from the mapfile, the
countries as well as the country names are displayed. However, when I
dynamically build my layer in PHP (commenting out the whole
'country_name' layer-definition in the mapfile, of course), the
countries are displayed okay, but the country names are *not* displayed
at all. I do want to display the country names from the layer I defined
in the PHP script.

Any guru can see what's wrong?

All the best,
Maarten


=== mapfile ===
LAYER
  NAME country_name

    "RESULT_FIELDS" "CNTRY_NAME"
 END
  TYPE POLYGON

=== php script (part of it) ===
    $layerObj1 = ms_newLayerObj($gpoMap);

    $classObj1 = ms_newClassObj($layerObj1);
    $classObj1->set("name","cntry_name");
    $styleObj1 = ms_newStyleObj($classObj1);
    $styleObj1->color->setRGB(255,255,191);
    $styleObj1->outlinecolor->setRGB(0,0,0);

    $classObj1->label->set("size",MS_GIANT);
    $classObj1->label->set("position",MS_CC);
    $classObj1->label->set("minfeaturesize",40);
