Sorry for a late response. Of course it is possible. You just need to save the path to your image in the xml file. After all it is just a string, so It shouldn’t be a bigger problem to do it in php. I hope this helps.

Thanks for the great tutorial… really informative! I just created an image uploader in the infowindow using the hidden iframe approach. I can get a thumbnail to appear in the infowindow and have the original image stored in a seperate folder, however I can’t get the thumbnail stored in the XML file and subsequently saved after submission of the form.

My question for anyone, is if this is possible and what steps would I take to get this to function properly? Thanks in advance for any insights which could be provided.

Kind regards

Hi Markus,

if you want to support database just place your code in php file. Instead of file_get_contents() you just need to retrieve results from your database and return a string with xml header. I hope this helps.

Thanks for the help man! It was my fault… I didn’t have the php code at top of my index.php.

Doh!

Now I’m going to work on getting different types of markers for different objects.

@Jeff

try to set error_reporting(E_ALL) and check, what kind of errors are you getting.

You should also try to check, if your php is compiled with –enable-simplexml (should be by default).

You can also check, which value is returned by a function extension_loaded(’xml’).

If you don’t have SimpleXML support, you should just build your xml file by creating it line by line, e.g.

$xml = ‘‹markers lat=”…”›’;
$xml .= ‘‹markers lat=”…”›’;

and so on. I hope this helps. Let me know.

Hey there, very nice code. I’ve ran into one issue I can’t get the markers to save even when I use your markers.xml and index.php with my api code. I thought it might be permissions but changed my markers.xml to 777 and still no workie.

Any suggestions?

@ash

on what kind of user interaction do you want to delete these markers? If you just want to provide a delete button of a users marker, you need to identify him or her anyhow. If you just want to delete some of them, you either edit xml file or write GUI for editing it.

Very nice code. I have implemented it on a test site I’m working on but have ran into a dead end. I have been trying to write a function to easily delete markers.

Any thoughts?

Thanks again.

@sjp

without knowing, how you want to handle saving and retrieving the data, it is hard to find an answer. Probably it should be pretty easy with AJAX instead of reloading the page every time. Basically you can create an instance of map1 and map2 with:

var map1 = new GMap2(mapContainer1)
var map2 = new GMap2(mapContainer2)

and follow the naming convention to retrieve the information from map1 and display it on map2. If you provide me more information, maybe I can help you further.
