same effect as CGI mode=itemquerymap but with PHP/mapscript

[Rodrigo Martín LÓPEZ GREGORIO]

Finaly I figured out how to get it working; in my php mapscript file I added
the next code:

if ($_GET['mode'] == 'itemquerymap') {
 $qstring = explode("=",$_GET['qstring']);
 $map->getLayerByName($_GET['qlayer'])->queryByAttributes($qstring[0],str_replace("\\","",$_GET['qstring']),MS_SINGLE);
  // I remove the \ characters of the qstring
}

And at the end of my file:

if ($_GET['mode'] == 'itemquerymap') {
   $image=$map->drawQuery();
} else {
   $image=$map->draw();
}

So if the mode is itemquerymap I draw the query; otherwise I make a normal
draw.

Rodrigo.
