I have a database driven google map v3 which uses markerclusterer, everything is working fine, but I would like to show additional data, instead of just being able to show one direct result from the database (like the id or name etc). I had it working before using markerclusterer to the level of having a hyperlink, and would like to achieve a similar result.
The code I currently have is

I'm sure this is something so basic, but I've been looking at it for an hour, and I can't see it. I'd appreciate a fresh pair of eyes. This is a pretty basic Google Maps API v3 project, copied almost verbatim from the cookbook, which loads data from a MySQL database into an XML file, and then loads data from the XML file into the map.
Here's 3 sample markers from the XML file:
<markers>
<marker name="Total Beverage" type="2" address="9359 Sheridan Blvd Wesminster, CO 80031" lat="-105.053293" lon="39.8658159"/>
<marker name="Union Jack Liquor" type="2" address="1160 S Boulder Road Louisville, CO 80027" lat="-105.1301647" lon="39.9868051"/>
<marker name="Argonaut Wine and Liquor" type="2" address="760 E Colfax Denver, CO 80203" lat="-104.9785574" lon="39.7398985"/>
</markers>
And here's the code that generates the map.

The map centers at the right spot, and zooms to the right level, but the markers don't show up. Thanks for any pointers.
You have the latitude and longitude backwards in your xml:
lat="-105.053293" lon="39.8658159"
Your map is centered at :
var latlng = new google.maps.LatLng(39.909939, -105.078369);
So im using PHP/MySQL to load the information into a XML which works then I have this code below that is supposed to make the map and load the xml and plug it into the markers when clicked. This is almost 100% copy pasted from googles tutorial
https://developers.google.com/maps/articles/phpsqlajax_v3#createmap
Any help would be lovely I have been struggling with this for days

I am pretty experienced when it come to php mysql, but javascript has got me scratching my head. I am trying to add google maps to my website to show where picture in my database were taken. I got the static google map to work, but it will only display 37 markers due to the url character limitations. I followed the tutorial at google maps api docs, and i have a map that will display all the coordinates for the images in my database. My problem is that i cannot for the life of me figure out how to get the map to auto center and auto zoom to fit all of my markers. my test website for my map is at maptest. I found this tutorial on how to auto center/zoom my map by no matter where i put his code i get errors. this is the code i have for my map that does not auto zoom/center:

Tried this?
var fitToMarkers = function(markers) {
var bounds = new google.maps.LatLngBounds();
var length = markers.length;
for (var i = 0; i < length; i++) {
bounds.extend(new google.maps.LatLng(markers[i].lat, markers[i].lng));
map.fitBounds(bounds);
}
};
I'm using the code below to link an HTML list to markers on a map. When I click on the markers, the InfoWindow opens without any problem. However when I click on the list item, although the map pans correctly and centres on the appropriate marker, I cannot get the InfoWindow to open at the same time.

You've binded the click event on the marker to open an infowindow. What you want to do is trigger that click, i.e. as if the user had done it themselves.
Something like this:
google.maps.event.trigger(marker, 'click');
The hard part will be for you to identify which marker the click event is firing on. Suggest you have an array of all your markers. At the same time as you call scrollToMarker, also do this trigger, and pass through the index parameter too, to identify which marker in your array you're wanting to 'click'
Update: ok, here's a working example of what I mean. I've removed your Ajax request part and put in some dummy marker data, but it should be simple enough for you to figure out how to integrate into your code.

I'd now like to be able to extend the functionality of the page a little further by adding a sidebar, whereby if the user clicks on the location in the sidebar it highlights the selection with a yellow background and then pans the map to the center it on the associated marker where it opens up the info window. If the user should click on the marker, I would like the info window to open and the associated location on the sidebar to be highlighted, again, with a yellow background.
I have been researching this for sometime and I found the exact type of sidebar that I would like here http://econym.org.uk/gmap/example_map2c.html but the problem is, is that this is in v2 of the Google maps API.
I just wondered whether it would be at all possible that someone could please show me what I need to do to get this to work.

My recommendation it's looking first documentation there you can find examples and a tutorial, then go to google playgorund which have live examples. It's completely possible make the sidebar, the only thing that you need to consider it's if the sidebar will be inside or outside of the map, in the link of the playground i are the example to make you're own controls. To store the data you need to understand how are make asynchronous calls by ajax to save the locations
