[mapserver-users] php/mapscript and OWS

[ROBERT HOLLINGSWORTH]

I tried your sequence on my mapfile and it worked.  My original code was missing this  at the bottom:

ms_iogetStdoutBufferBytes();

I'd been experimenting with  header(...) and ms_ioresethandlers()  but not necessarily at the same time, and without the "Bytes" func.  I need to go back and read the descriptions of these  ms_io funcs.

many thanks,
Robert

  what does you php script looks like?  Quick test I did with a png 
output and works looks like this:

  request : 
http://localhost/msapps/wxs/test.php?SERVICE=WMS&VeRsIoN=1.1.1&Request=GetMap&LAYERS=WorldGen_Outline&FORMAT=png&WIDTH=400&HEIGHT=300&SRS=EPSG:4326&FORMAT=png&WIDTH=400&HEIGHT=300&STYLES=&BBOX=-180.0,-90.0,180.0,90.0&SLD=http://localhost/msapps/world_testdata/tests/sld_tests/sld_line_multi_filter.xml

test.php



dl("php_mapscript.dll");

$request = ms_newowsrequestobj();

$request->loadparams();

ms_ioinstallstdouttobuffer();

$oMap = ms_newMapobj("f:/msapps/world_testdata/map/world_testdata.map");

$oMap->owsdispatch($request);

$contenttype = ms_iostripstdoutbuffercontenttype();

//if ($contenttype == 'image/png')
    header('Content-type: image/png');

ms_iogetStdoutBufferBytes();

ms_ioresethandlers();

?>


Best Regards
