Hello Armin,
thanks for information.
I have used the function but I have a problem when the features don't exist
and the application is locked because it doesn't manage to calculate the
extension.
I have find a solution changing the function
function getMapInitURL($map, $zoomLayer, $zoomQuery)
I have added
if ( $numResults == 0){
// set initial max/min values with the value of the map
$initExtent2 = ms_newrectObj();
$initExtent2 = $this->map->extent;
$mExtMinx =$initExtent2->minx;
$mExtMiny =$initExtent2->miny;
$mExtMaxx =$initExtent2->maxx;
$mExtMaxy =$initExtent2->maxy;
} else {
// initial max/min values
$mExtMinx = 999999999;
$mExtMiny = 999999999;
$mExtMaxx = -999999999;
$mExtMaxy = -999999999;
}
In my opinion, this addition could be useful also in other cases and
I suggest to add it in the next release.
Thanks in advance
Leonardo

Oggetto: Re: [pmapper-users] R: zoom to features from external application
all you need is to modify the function 'getMapInitURL()' in
init/initmap.php to perform the query you need.
For zooming to 2 countries you might be able to specify the full
Mapserver query string in the URL with the default setting, but you
need to know how to compose the query string, could be something like
'[NAME]'='Italy' OR '[NAME]'='Spain'
one might need to encode some characters, never tried though.
maybe you can do the same with 2 fields included, just read the MS
docs about expressions/filters and try it, and check the PHP (and or
JS) error log if it does not work.
