Add Google Directions Map to your forum

Demo: Link

Get the google API key here: http://code.google.com/apis/maps/signup.html

Create a new file called maps.php in your forum root.

Once created add the following inside the file:
<?php require("/home/**************/public_html/SSI.php");
$context['page_title_html_safe'] = 'Google Directions';
template_header(); 

echo
'
<script src=" http://maps.google.com/?file=api&amp;v=2.x&amp;key=GOOGLE KEY GOES HERE"
type="text/javascript"></script>
<script type="text/javascript">'

GEvent.addListener(gdir, "error", handleErrors);

setDirections("San Diego", "3666 Madison Ave. San Diego, CA 92116", "en_US");

Replace the omitted part here with the path of your forum in line 1:
require("/home/**************/public_html/SSI.php");

Replace "GOOGLE KEY GOES HERE" in the code with your google API key number.

Should be available to see at yourforum.com/maps.php
