This plugin allows the administrator to keep track of a history of geographical locations. It was developed for a travel blog and the geographical locations were drawn onto a Google Maps widget so that visitors could keep track of the blogger’s traveling.
A live example can be seen on <a href="http://yoranbrondsema.net" title="Yoran Brondsema's travel blog" rel="nofollow ugc">the author’s travel blog</a> (in Dutch).
Its main features are:
<ul>
<li>Add, edit and remove locations easily from the Admin panel</li>
<li>Enter geographical coordinates manually or parse from a Google Maps URL</li>
<li>Assign a date to each location for a true history of locations</li>
<li>Assign a label to each location for easy identification</li>
<li>Exposes a simple API to the front-end</li>
<li>Dynamically request locations with AJAX</li>
</ul>
The plugin is administrated from the admin (addition and removal of geolocations) and it exposes an API to the front-end. Once the plugin is installed, a theme can call the following functions:
<ul>
<li><code>lochis_get_location_history()</code>: returns an array containing the whole history of geolocations, sorted by ascending date.</li>
<li><code>lochis_get_latest_location()</code>: returns only the most recent geolocation.</li>
</ul>
Each of these functions also has an AJAX-equivalent that returns a JSON-object instead of a PHP object. This way you can use the geolocations in Javascript, for instance to be shown in a Google Maps widget. The AJAX functions are:
<ul>
<li><code>lochis_ajax_get_location_history()</code></li>
<li><code>lochis_ajax_get_latest_location()</code></li>
</ul>
