Tileindex of DGN's being opened as shapefile layer

[Delfos, Jacob]

Hi,
 
Just to provide some additional information: the map displays fine in
mapserver, but not in php_mapscript. It appears that php_mapscript
assigns a shapefile connectiontype to this layer, causing it to try to
open the DGN's as shapefile. In the mapserver CGI, this doesn't happen.
Can anyone with a better understanding of the difference between the two
tell me what I can do to get around it?
 
regards,
 
Jacob

as shapefile layer
	
	

	Hi All, 

	I'm having some trouble creating a tile-index of DGN's, using
php_mapscript (Chameleon). My tileindex is a shapefile. But I think the
layer should be treated as OGR, yet the connectiontype seems to indicate
it thinks it is a shapefile layer. According to my PHP log, it tries to
open it as a shapefile, which obviously fails:

	[20-Feb-2006 14:45:49] PHP Warning:  [MapServer Error]:
msDrawMap(): Failed to draw layer named 'DGNs'.

	I based my layer definition on
http://mapserver.gis.umn.edu/docs/howto/ogr_howto/#tileindex-with-ogr
<http://mapserver.gis.umn.edu/docs/howto/ogr_howto/#tileindex-with-ogr>
: 

	LAYER 
	  NAME "DGNs" 
	  TYPE LINE 
	  STYLEITEM "AUTO" 
	  CONNECTIONTYPE OGR 
	  TILEINDEX "dindex.shp,0" 
	  STATUS ON 
	  CLASS 
	     COLOR 150 150 150 
	  END 
	END 

	The DBF of the shapefile has 1 column, with these values: 

	location 
	C:\data\10nwa.dgn,0 
	C:\data\10nwb.dgn,0 

	I am using php_mapscript 4.6.1, with php 5.05. Can someone tell
me what I'm doing wrong? 

	Regards, 

	Jacob
