Use custom info box on google maps api - php

Question

I have been following a tutorial to set up a google map for my website here and I have completed this, however I now want a custom info box that pops up when you click the icon. (at the moment it pops up with googles default)
I was trying to use this code to do it, but every time I try none of the icons appear.
<script type="text/javascript">
//<![CDATA[
var customIcons = {
restaurant: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_blue.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'
},
bar: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_red.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'
}
};
var labelText = "City Hall";
var myOptions = {
content: labelText
,boxStyle: {
border: "1px solid black"
,textAlign: "center"
,fontSize: "8pt"
,width: "50px"
}
,disableAutoPan: true
,pixelOffset: new google.maps.Size(-25, 0)
,position: new google.maps.LatLng(49.47216, -123.76307)
,closeBoxURL: ""
,isHidden: false
,pane: "mapPane"
,enableEventPropagation: true
};
function load() {
var map = new google.maps.Map(document.getElementById("map"), {
center: new google.maps.LatLng(47.6145, -122.3418),
zoom: 13,
mapTypeId: 'roadmap'
});
This is the part that im changing at the moment
var infoWindow = new google.maps.InfoWindow;
to this
var infoWindow = new infoBox(myOptions);
.
// Change this depending on the name of your PHP file
downloadUrl("phpsqlajax_genxml.php", function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var name = markers[i].getAttribute("name");
var address = markers[i].getAttribute("address");
var type = markers[i].getAttribute("type");
var point = new google.maps.LatLng(
parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var html = "<b>" + name + "</b> <br/>" + address;
var icon = customIcons[type] || {};
var marker = new google.maps.Marker({
map: map,
position: point,
icon: icon.icon,
shadow: icon.shadow
});
bindInfoWindow(marker, map, infoWindow, html);
}
});
}
function bindInfoWindow(marker, map, infoWindow, html) {
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(html);
infoWindow.open(map, marker);
});
}
function downloadUrl(url, callback) {
var request = window.ActiveXObject ?
new ActiveXObject('Microsoft.XMLHTTP') :
new XMLHttpRequest;
request.onreadystatechange = function() {
if (request.readyState == 4) {
request.onreadystatechange = doNothing;
callback(request, request.status);
}
};
request.open('GET', url, true);
request.send(null);
}
function doNothing() {}
//]]>
</script>
Any help to say where i'm going wrong would be appreciated

Answer 1

Assuming that you have included the infobox-library and the php-file returns the expected XML there is nothing wrong except of this:
var infoWindow = new infoBox(myOptions);
it has to be:
var infoWindow = new InfoBox(myOptions);
