Hello, I did some tests with the WXS warpper in PHP Mapscript as well. I used MapServer version 6.0.0 Base is a working map file (datasource is a postgresql database) which produces maps and capability documents using plain WMS requests like
http://localhost/cgi-bin/mapserv_600?map=postgis.map&REQUEST=GetMAP&SERVICE=WMS&version=1.1.1&SRS=EPSG:4326&WIDTH=600&HEIGHT=600&LAYERS=geobilder&STYLES=&FORMAT=image/png&TRANSPARENT=true&BBOX=5.86628568,47.27360151,15.0486318,55.05826185 If I am trying to send a GetMap request with the WXS Mapscript wrapper I run into trouble as well. I am able to request the Capability document but never managed to get a Map request working Therefore one question. If I print out the members of the OWSRequestObj (http://mapserver.org/mapscript/php/index.html#owsrequestobj) what would be the expected values? My sample script shows: printf('numparams: %d - type: %s', $owsRequest-> numparams, $owsRequest->type ); numparams: 10 - type: 4294967295 ^^^^^ The number of parameters are correct, but according to the documentation (int type (read-only): MS_GET_REQUEST or MS_POST_REQUEST) I would expect something like 0 or 1 for the 'type' member var_dump( MS_GET_REQUEST ); int(0) var_dump( MS_POST_REQUEST); int(1) Could it be that something is going wrong here? Thanks.
