Hello,

I can't use queryByIndex result on Postgis layers (Mapserver 6.4.1, PHP 5.5.12, Postgis 2.0).
$iIndexLayer=1;
$aQueryIndex=new array(2211, 2215);
foreach($aQueryIndex as $iIndex){
$oLayer=$oMap->getLayer($iIndexLayer);
$oLayer->queryByIndex(-1,$iIndex,MS_TRUE);
}

    $oLayer=$oMap->getLayer($iIndexLayer);
    echo $oLayer->getNumResults();  // return 2, it's OK

     for ($i=0; $i<$oLayer->getNumResults(); $i++){
        $oShape=$oLayer->getShape($oLayer->getResult($i));
        echo $oShape->index; // return always 2215, the last one
    }

I've a second problem if I do :
$sMapFile="my_mapfile.map.qy";
$oMap->savequery($sMapFile);
$oMap->loadQuery($sMapFile);

    $oLayer=$oMap->getLayer($iIndexLayer);
    echo $oLayer->getNumResults();  // return 3 instead of 2

If I do a savequery(), the getNumResults() is always increases 1.

I see that issue :
#4076
Indeed, the getNumresults() function works but the result can't be use.

In version 5.4 of Mapserver everything works fine.

I looked the code (mapquery.c), this is complex, maybe there is a problem with the result index ?!

Thanks,

Fabien Marty

Thank you, @fabien-cat. With postgis, the result index is always 0, which is the row number. See #4932 for further explanation.

Thanks @mkofahl , so why there's a good number result but always the same index for Shapes result ?
There's a problem with the function msQueryByIndex() or addResult() ?
