I'm trying to create a function in mapscript to assign the value of the
extents of the reference map.
On execution the map hangs, indicating that there are no reference map
extents set.
However, at the bottom of this function when the values of the
reference map extents are echo'd they are fine.
Can anyone see what I am doing wrong here?????
Is there a call to another function in PMAPPER that is voiding my extents???
function setRefMapExtents()
{
$PM_MAP_FILE = $_SESSION['PM_MAP_FILE'];
$map = ms_newMapObj($PM_MAP_FILE );
$refmap = $map->reference;
if (isset($_SESSION['mapMaxExt'])) // this holds the extents of
my main map frame - I will use the same for the reference map extents
{
$refmapextent = $refmap->extent;
$me = $_SESSION['mapMaxExt'];
// $refmapextent = ms_newrectObj(); // don't need to create
new rec obj, as already have a handle on existing
$refmapextent->setextent($me["minx"],$me["miny"],$me["maxx"],$me["maxy"]);
}
$_SESSION['refmapextent'] = $refmapextent;
$initRefExtent2 = $refmap->extent; // check to see if the extent values
have changed
foreach(get_object_vars($initRefExtent2) as $prop=>$val) //spew out the
ref extent values so I can see them
{
echo '<p>'.$prop.'='.$val.'</p>';
};
} // END Function
