[mapserver-users] PHP Mapscript Newbie: trouble with layers and logging.

[Ben Logan]

Hello, all.

I finally recompiled PHP so that I could use Mapscript with it, and I
have followed the "PHP/Mapscript By Example HOWTO."  But now I've run
into some trouble getting additional layers to display.  I also can't
seem to get it to write a log.

First the layer issue:

I have the following code:

...
$map = ms_newMapObj($map_path.$map_file);
...
$image = $map->draw();
$places_layer = $map->getLayer(1);
$places_layer->status = MS_ON;
$places_layer->draw($image) or print("<h3>Unable to draw layer.</h3>");
$image_url = $image->saveWebImage(MS_PNG, 1, 1, 0);
...

This is always unable to draw the layer.  I tried using
"getLayerByName" as well, but with no success.

As for the logging, you can see that I have a LOG defined in my WEB
object in the map file.  Also, test.log is writable by the web server.

Here's the map file:
