'reloadMap' is a JavaScript function,
the call
unset($_SESSION['url_points']);
is PHP code... mixing both will not work... ;-)
try using
PM.setSessionVar('url_points', 'null');
I'd recommend that you do not change this in the Javascript files
directly but that you add it in a *.js file under your config directory,
like
$.extend(PM.Map,
{
/**
* Reload application
*/
reloadMap: function(remove) {
var mapurl = PM_XAJAX_LOCATION +
'x_load.php?'+SID+'&zoom_type=zoompoint';
if (remove) {
mapurl += '&resultlayer=remove';
PM.extentSelectedFeatures = null;
PM.setSessionVar('url_points', 'null');
}
this.updateMap(mapurl);
}
});
In order for this to work correctly you will also need to replace the
file 'incphp/xajax/x_setsessionvar.php' with the one from SVN trunk:
