This plugin is for developers and is meant to be used to enable Google Maps integration. While it does come with a default location, developers will want to feed the plugin a nested array of location data. This data can be manually curated or retrieved through external means.
You need to use the filter <code>ab_google_maps_markers</code> and return the new nested array.
Example:
<pre><code>function new_array( $markers ) { $markers = (object) array( 
 array( 
 'lat' => '30.266132', 
 'lon' => '-97.745825', 'title' => 'Gingerman Austin', 'address' => '301 Lavaca St, Austin TX 78701' ), array( 'lat' => '30.2658', 'lon' => '-97.735691', 'title' => 'Easy Tiger Bake Shop and Beer Garden', 'address' => '709 East 6th St, Austin TX 78701' ), ); return $markers; } add_filter( 'ab_google_maps_markers', 'new_array' ); </code></pre>

This plugin is meant to be used in conjunction with external code that provides necessary coordinates to the plugin.

I originally posted on here that this plugin added malware to my site because Google's warning in Webmaster Tools indicated that the files from this plugin were infected but it didn't show the warning on any other files. However, after further investigation, this plugin had nothing to do with the malware. So I am updating this review and changing it to 5 stars, because it is in fact a great plugin. To the plugin author, I apologize for the inconvenience of my initial review!



UPDATE: This is a great plugin

Apply styles to your Google Maps with the official Snazzy Maps WordPress plugin.
