Thank you very much!
I found this very useful!
but now I have this problem:
in the same way I would set "filter" instead of "DATA" but give me the
error:
Fatal error: Property 'FILTER' does not exist in this object. in
C:\ms4w\Apache\htdocs\sicmed\incphp\globals.php on line 67
my code is:
$wdata = 'aree ="' .$_COOKIE['nome_visitatore'].'"';
//$wdata= 'the_geom from bacini where aree = "'
.$_COOKIE['nome_visitatore'].'"';
if ($wdata != '') {
$mylayer=$map->getLayerByName('bacini');
$mylayer->set("filter",$wdata);
}
my mapfile is:
CONNECTIONTYPE POSTGIS
CONNECTION "host=localhost dbname=cms user=postgres password=*****
port=5432"
DATA "the_geom FROM bacini"
FILTER "aree = ''"
it's possible?????
Thanks!
