google maps onClick marker

ok I have a map that displays neighboring locations with a small marker and the current location with a large marker. (see the code below.)

The neighboring locations are created with a php loop.

I want an onclick event of the small markers to send my users to a new page.

I tried this :
 GEvent.addListener(marker, "click", function() {
          window.location.href="wiki_locations.php?loc_id=";
        });

but it adds the onclilck event to the large marker only.

the other problem I dont know how to solve yet is the location

wiki_locations.php?loc_id=

I need to add a variable loc_id= to the location with a variable unique to the marker which will also come from my php loop.  

how do I go about this?

var tinyIcon = new GIcon();
tinyIcon.image = "http://labs.google.com/ridefinder/images/mm_20_red.png";
tinyIcon.shadow = "http://labs.google.com/ridefinder/images/mm_20_shadow.png";
tinyIcon.iconSize = new GSize(12, 20);
tinyIcon.shadowSize = new GSize(22, 20);
tinyIcon.iconAnchor = new GPoint(6, 20);
tinyIcon.infoWindowAnchor = new GPoint(5, 1);
 
// Set up our GMarkerOptions object literal
markerOptions = { icon:tinyIcon };
	  
      function createMarker(point) {
        var marker = new GMarker(point);
		
        GEvent.addListener(marker, "click", function() {
          window.location.href="wiki_locations.php?loc_id=";
        });
        return marker;
      }
 
      // Display the map, with some controls and set the initial location 
      var map = new GMap2(document.getElementById("map"));
      map.addControl(new GLargeMapControl());
      //map.addControl(new GMapTypeControl());
      map.setCenter(new GLatLng(<? echo $glat; ?>,<? echo $glong; ?>),9);
    
 
      
//loop through neighbouring locations
<?
while ($get_info = mysql_fetch_row($result2)){	
 
?>
   var point = new GLatLng(<? echo $get_info[3]; ?>,<? echo $get_info[4]; ?>);
      var marker = createMarker(point)
       map.addOverlay(new GMarker(point, markerOptions));
  <? } ?>
	   // show large marker for current location.
var point = new GLatLng(<? echo $glat; ?>,<? echo $glong; ?>);
      var marker = createMarker(point)
      map.addOverlay(marker);
    }
    
    // display a warning if the browser was not compatible
    else {
      alert("Sorry, the Google Maps API is not compatible with this browser");
    }
