You can easily use it with newest Ditto. Here's a slightly modified code:
<?php
/* Snippet name: [[GoogleMapMarker]]
* Version: 1.0c for ditto v2+
* Author: doze <dozebox@gmail.com>
*
* Snippet to generate goolemaps map and place markers
* to the maps from documents.
*
* Installation:
* -------------
* 1. Create a snippet "phx:slashandstrip" with this content:
* return addcslashes(preg_replace("~([\n\r\t\s]+)~"," ",$output), "'");
*
* 2. Call the snippet in some document: [[GoogleMapMarker? &apikey=`ABQIA..`]]
*
* How to place markers:
* ---------------------
* 1. Create a folder in MODx manager what will keep the marker documents, can be unpublished.
* 2. Create a new document inside that folder what will be the marker
* - Title: Will be used as the marker "sidelink" text (example: My home)
* - Description: The coordinates for the marker (example: 63.098332,23.056698)
* - Document content: HTML to show in the marker popup.
* NOTE: You have to escape all ' characters by putting backslash before them, e.g. \'
* 3. Add the &startID parameter to the snippet call pointing to the folder what has the marker documents
* example: [[GoogleMapMarker? &apikey=`ABQIA..` &startID=`52`]]
*
* Example GoogleMapMarker template chunk (&tpl)
* ---------------------------------------------
* The template must have 2 divs. A div for the map and div for the side links. That's it.
*
* <div id="map" style="float:left; width: 350px; height: 350px;">Loading map...</div>
* <div id="maplinks" style="margin-left: 10px; padding-right: 10px; float: left; display: block; height: 350px; overflow: auto;"></div>
*

You also need to create a snippet "phx:slashandstrip" with this content:
<?php
return addcslashes(preg_replace("~([\n\r\t\s]+)~"," ",$output), "'");
?>
And have PHx installed ofcourse.
You don't have to create the "GoogleMapCode" chunk anymore and no need to escape quotes + it can handle multi-line bubble texts.. I will do a bigger update later when I have time.
