Pronamic Google Maps

This plugin makes it easy to add Google Maps to your WordPress post, pages or other custom post types.


With this plugin a user can easily add location (latitude, longitude) meta data to a page, post or a custom post type. This plugin adds a meta box with an Google Map to the post editor. Users can easily drag and drop a marker on the map to save location meta data for a post.

There are quite a few Google Maps plugins available in the WordPress Plugin Directory. Why should you use the Pronamic Google Maps plugin:

  • Google Maps API version 3 Most of the available plugins still use the Google Maps version 2 API. To use the Google Maps v2 API you have to require an API key and include this in the plugin configuration. The Pronamic Google Maps plugin uses the Google Maps version 3 API. Wich no longer requires an API key, so you don't have to configure this plugin.

  • Shortcode Easily integrate a Google Maps in your post content:

    [googlemaps static=true]
    [googlemaps static=true label=M]
    [googlemaps width=200 height=200]
    [googlemaps new_design=true]

    Also easily integrate an Google Maps mashup in your post content:

    [googlemapsmashup query="post_type=company&nopaging=true" map_type_id="satellite"]
  • No extra tables Some plugin create additional tables in your WordPress database to store additional data. In many cases this is not necessary, it's only pollutes your database. WordPress offers enough functions to store additional data.

  • Custom Post Types A lot of the WordPress plugins are developed before WordPress 3 was launched. These plugins not always use the new features of WordPress 3. Many plugins only focus on posts and pages, but not on other custom post types. This plugin does!

  • Mashup Easily create an Google Maps mashup to show all your posts on Google Maps. You can use an very powerfull pronamic_google_maps_mashup() function or the shortcode. Both methods allow you to pass custom WordPress query parameters.

  • No notices or warning Pronamic is one of the few companies that develop all WordPress plugins in debug mode. This results in high quality plugins with no errors, warnings or notices.

Custom Post Types

The nice thing about this plugin that developers can configure on what post type the meta box should be visible. Developers can activate the meta box for every custom post type they registered with the register_post_type function.

For example: if a developer registers a custom post type for real estate it is very easy to activate and manage location data for that post type. It comes in handy for all kind of custom post types!

  • Projects
  • Real estate
  • Restaurants
  • Accommodations
  • Hotels
  • Ships
  • Ports


The plugin uses the latest GEO microformat standards.

<div class="geo">
    <abbr class="latitude" title="37.408183">N 37° 24.491</abbr> 
    <abbr class="longitude" title="-122.13855">W 122° 08.313</abbr>
