Adding GeoRSS Functionality

WPMU Team — Fri, 06 Feb 2009 05:29:09 +0000

If you would like to give your Wordpress RSS feed full GeoRSS compatibility, it’s really quite simple - all you need to do is copy and paste the following piece of code into your functions.php file:

function geo_header() {
echo 'xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#" xmlns:georss="http://www.georss.org/georss"';
}
add_action('rss2_ns', 'geo_header');

function geo_points() {
global $wp_query;
$map_lat_geo = get_post_meta($wp_query->post->ID, 'map_lat', true);
$map_long_geo = get_post_meta($wp_query->post->ID, 'map_long', true);
echo '' . $map_lat_geo . '';
echo '' . $map_long_geo . '';
echo '' . $map_lat_geo . ' ' . $map_long_geo . ''; }
add_action('rss2_item', 'geo_points');

However, please remember that in order to view the GEO-Tagged RSS feed, you will need to use the full URL, such as http://yourdomain.com/?feed=rss2

You may be asking how can you then add coordinates to posts…?

Also relatively simple - just create custom fields labeled:

map_lat
map_long

…As referenced above within the code.

If you need a really easy way to find the coordinates you need, we strongly recommend the use of the Mapeed.AdressChooser API

If you’re looking for an example of what can then be done with the Geo-Tagged RSS Feed, please take a look at the following:

The KL News Network Geo-Tagged Page, which does not use any plug-ins:

This hack has been provided for those looking to incorporate Geo-Blogging functionality directly into their theme, or that need a step in the right direction as far as developing your first Geo-Tagged plug-in may be concerned.

For those curious as to exactly what code is needed to generate a map like the one seen above, all you need to do is include the following code:

Display Post & Comment Count

WPMU Team — Sun, 11 Jan 2009 12:37:37 +0000

This nifty little hack will display a post and comment count and can be easily edited, but basically, all you need to do is paste the following code into your PHP file where you want the sentence displayed:

$numposts = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_status = 'publish'");
if (0 < $numposts) $numposts = number_format($numposts);
$numcomms = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments WHERE comment_approved = '1'");
if (0 < $numcomms) $numcomms = number_format($numcomms);
echo $numposts.' articles have been published on this site,';
echo " sharing a total of ".$numcomms." comments.";
?>

This will display XX articles have been published on this site, sharing a total of XX comments, and will only work correctly with Wordpress - if used with MU, it will only display the number of posts and comments specifically for the blog it is seen from…

If you want to define the variables in one place and then re-use the stats as numbers on their own (so they can be better styled) all you need to do is split the code as follows - by first defining the variables:

Then call the numbers using either of the following:
