The GMap module is a module that has 4 essential parts. The first part
an API that allows other modules or administrators to convert either an
array of specifications or a macro text into a html/javascript text that
will include the google map on their page.
The second part is a macro generator which will allow you to interactively
create a gmap macro suitable for using with this module.
The third part is the filter, which allows you to take the text created
from the macro and insert it into a node and the filter will convert this
into a google map shown on the node.
The fourth part is a user interface that allows users to enter their location
in a google map and then a map can be viewed that can show where users are
from around the world. Note that the user functionality must have a table
added to the database. However, the rest of the module will work fine if
this table is not activated and the user functionality is not turned on in
the settings page.
Installation
------------
1) copy the gmap directory into the modules directory
2) edit the theme files to ensure that the html file has the following at
the top of each page (the first one is recommended by Google, the
second is required for the lines overlays to work in IE:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml">
3) Get a GMap API Key at http://www.google.com/apis/maps/signup.html
4) enable the 'gmap module' in drupal
5) edit admin/settings/gmap to include the key you received from google and
change any other default setting.
6) configure an 'input format' so that the gmap filter is activated. If
this will be on a 'html filtered' format, ensure that the weighting is
such that the HTML filter comes before the gmap filter.
7) (optional) If the user functionality will be used and location.module is
not installed, the location table must be added to the database (as
defined in location.mysql) and it must be turned on in the gmap settings
page.
Instructions
------------
A gmap macro can be created on the gmapmacro page and the text can then be
copied and pasted into any node where the gmap filter is enabled.
Default settings will be the initial settings and will be used for any
parameter not inserted into the macro.
A gmap can also be inserted into any page or template by using either the
macro text and the function gmap_from_text($macro); or using the
function gmap_from_var($gmapvar); where $gmapvar is an associative array.
After you insert the macro into a node, you can edit it using raw values
that you get from elsewhere to create a set of points or lines on the map.
It should be noted that when editing the macro you are not limited to 3
points on the map. An unlimited number of points may be added separated
by the '+' symbol. This could be used, for example, to plot a series of
points that you get from a GPS.
It should be noted that currently the macro parsing (filter) has much more
functionality than can be created using the macro creator.
Demo
----
To see the macro creation tool go to:
http://vancouver.cyclehome.org/gmapmacro
To see an example a node with the macro inserted go to:
http://vancouver.cyclehome.org/
User
----
If the user functions are enables (on the settings page) then users are
able to edit their location using an interactive google map on the edit
user page. Alternatively they can enter in their Latitude and Longitude
and the map will set their location.
Any user that has permission for "show user map" will then be able to see
a map of all of the user locations at: q=gmapusers if a user has permission
to "user location" when they click on the marker they will see what user it
is.
- There is a conflict between the xmaps script and the javascript that does
the collapsing menus. If want to use the xmaps functionality, it is
recommended that you comment out all of the statements in the function
"collapseEnsureErrorsVisible()" in misc/collapse.js.
(xmaps not currently available so this is irreleveant now)
- The "dynamic" gmap method of inserting the initialization script does not
work with the filter functionality. (It does work with user functionality).
- When you preview a node, if the map is shown in the short version, it
will not be shown on the long version of the node, this is because only
one copy of a mapid can be shown on the same page.
- Significantly upgrade the macro creator
- The documentation (both in the code and this file) needs to be significantly
improved.
- create interface to geocoding for address or postal code to Long, Lat
conversion. Preferably on the client side of the javascript gmapmacro
page. (Probably wont do this, leave this functionality to location.module)
- Create an API that will allow the use of the macro creation tool in any
module.
- Create setting to suppress the option of changing some of the settings in
the macro creation page. This could be used so that all maps generated

Thanks to the following for their contributions:
Robert Douglass - for revamping some parts that really needed to be
revamped and cleaning up a lot of little things.
2005-12-xx:
- forked the 4.6/4.7 version, both versions will continue to be developed
for a while longer.
- added gmap user functionality
- width and height can be either px or %
- gmapmacro no longer needs to reload page (now works without clean url's)
- generalized gmap_from_var so that uses an array of points, or an array
of lines, ...
- 37518-Info windows associated with points (markers) can be shown
- can optionally include xgmap options such as circle/polygon/style types
2005-10-15 Quite a few fixes. (some reported in the project and some just
noted myself)
-Map controls are properly initialized in the gmapmacro page (can be
removed or changed)
-33949-Prevent errors from occurring if the Google Map key still blank
(not yet set)
-34036-Hybrid and Satellite maps now show in nodes
-33951-Long,Lat order and terminology corrected (note old Macros will
still work)
-33730-Alignment problem fixed. Now uses css.
-A few other little bugs
2005-10-10 Fix a number of little things and improve the macro interface
2005-10-09 Initial Release (probably too early)
