[Mapserver-users] resultcache using QueryByPoint (NULL? or empty?)

[Michael Härtel]

Hello all!

I'm sorry but i dont run out of problems ;):

i use following code:

$query=$querylayer->QueryByPoint($my_point_geo,MS_MULTIPLE,0);
$resultcache = $querylayer->resultcache;
($resultcache = $query->resultcache also produces NULL)

$numresult=$querylayer->getnumresult;
($numresult=$query->getnumresult also produces NULL)

$result = $querylayer->getresult(0);

after this this shows up with var_dump:

$query =1
$resultcache=NULL
$numresult=NULL
example for $result=object(stdClass)(3) { ["shapeindex"]=> int(11854) 
["tileindex"]=> int(-1) ["classindex"]=> int(0) } !!! success !!!

So i have a result (which makes my very happy and is a big step forward 
;) ) but i don´t know my resultcache always is empty.
I want to count the returned objects of course to program a loop for the 
output but i dont know what to count actually if my cache is empty. Do i 
have to make some changes to my configuration or are there some errors 
in my code?

Once again my target-layer (shouldn't there be an entry for 
["resultcache"] like it is shown for labelcache?

querylayer: object(layer)(35) { ["_handle_"]=> resource(51) of type 
(layerObj) ["_map_handle_"]=> resource(1) of type (mapObj) 
["numclasses"]=> int(1) ["index"]=> int(7) ["status"]=> int(1) 
["classitem"]=> string(0) "" ["name"]=> string(11) "WRS-2_frame" 
["group"]=> string(0) "" ["data"]=> string(9) "wrs2/wrs2" ["type"]=> 
int(2) ["tolerance"]=> float(5) ["toleranceunits"]=> int(4) 
["symbolscale"]=> float(-1) ["minscale"]=> float(-1) ["maxscale"]=> 
float(-1) ["labelminscale"]=> float(-1) ["labelmaxscale"]=> float(-1) 
["maxfeatures"]=> int(-1) ["transform"]=> int(1) ["labelcache"]=> int(1) 
["postlabelcache"]=> int(0) ["labelitem"]=> string(0) "" 
["labelsizeitem"]=> string(0) "" ["labelangleitem"]=> string(0) "" 
["tileitem"]=> string(8) "location" ["tileindex"]=> string(0) "" 
["header"]=> string(32) "H:\_webroot_\mapserv_header.html" ["footer"]=> 
string(32) "H:\_webroot_\mapserv_footer.html" ["connection"]=> string(0) 
"" ["connectiontype"]=> int(1) ["filteritem"]=> string(0) "" 
["template"]=> string(40) "H:\_webroot_\mapserv_query_template.html" 
["transparency"]=> int(0) ["styleitem"]=> string(0) "" ["offsite"]=> 
object(color)(4) { ["_handle_"]=> resource(52) of type (Unknown) 
["red"]=> int(-1) ["green"]=> int(-1) ["blue"]=> int(-1) } }

Thanks again for your help.

regards,

Michael
