Thanks Mr.Eric. I applied as u said. still i am not getting.
i defined in this way my MAP file layer
LAYER//Layer Def. start
NAME "Boundary"
STATUS ON
CONNECTIONTYPE OGR
CONNECTION "data/Boundary.tab"
TYPE POLYGON
CLASSITEM "NAME"
LABELITEM "NAME"
TEMPLATE "Malaya.html" //I defined here the template
METADATA
"DESCRIPTION" "Daerah"
"RESULT_FIELDS" "Name"
"WMS_TITLE" "Selected Information"
"WMS_ABSTRACT" "more information."
"WMS_SRS" "EPSG:26915"
END
CLASS
COLOR 255 255 200
OUTLINECOLOR 0 0 0
LABEL
MINFEATURESIZE 40
MINDISTANCE 150
POSITION CC
SIZE TINY
COLOR 0 0 200
END
END
End//Layer Def. end
for the above layer i written this code for geting the result
if ( isset($map_x) && isset($map_y) && strcmp($zoomdir, "QUERY_POINT") ==
0 )
{
echo "your at the query entery point just enter<br>";
for ($ilayer=0; $ilayer<=$map->numlayers; $ilayer++)
{
$selLayer = $map->GetLayer($ilayer);
// Pointing the map point to where the user clicked
$mappointq = ms_newpointObj();
$mappointq->setXY($map_x,$map_y);
echo $map_x. "<br>" . $map_y;
//$selLayer->{template} = "bogus.html";
$mappointq->setXY($map->width / 2,$map->height / 2);
$queryResult = $selLayer->queryByPoint($mappointq, MS_MULTIPLE, -1);
// here i am geting this error message " PHP Warning: MapServer Error in
msQueryByPoint(): No matching record(s) found"
echo $queryResult;
}
}
