Ed,
no, I am getting no more errors. The layer just does not appear. The layer
is turned on, and as you said, not only because of STATUS ON, but in my PHP
script I tell explicitly to turn it on again (actually after turning all
layers off):
$mapLayer = $map -> getlayerbyname("test");
$mapLayer -> set("status", 1);
Where does the "wms_title" refer to? Should it have the same title as the
WMS service layer? What is TYPE in this case? Originally it's a POINT
shapefile, but now it would be anyway a raster/image, no? When I try to
display the layer locally, everything turns up nicely.
LAYER
NAME 'test'
METADATA
'wms_title' 'test'
'wms_srs' 'epsg:4326'
'wms_connectiontimeout' '1000'
END
TYPE POINT

END
Ciao,

<dd>thanks for the quick answer. But the answer is: yes... As the WMS
service from where I want to retrieve a layer, does for sure work as it
has been implemented into another application, the problem can hardly be
on this side. I think, something is wrong on the map-file side. As the
BBox and other parameters are produced automatically by MapServer, the
URL used in the CONNECTION line below should be correct...<br><br>
<dd>Just to be sure: Can I have a map-file with multiple local layers,
which are accessed normally, and in addition a couple of WMS layers,
accessed as shown below? I was just wondering if MapServer would be
capable of merging then two, three or four different images, as each WMS
service sends its own image back. I know that I can overlay different
requests and thus images using simple HTML code, but I am not so sure
about the method I just wanted to implement. Stupid question?
