Custom taxonomies for post forms

Well, for anybody looking to implement cutom taxonomies, you can do it by using the gform_post_submission hook and custom fields. Something like this:

function tj_add_xtra_data( $form )
{
	if( $form['source_url'] == get_permalink( 824 ) )
	{
		require_once( WP_CONTENT_DIR . '/plugins/geo-mashup/geo-mashup-db.php' );

		$id = $form['post_id'];
		$lat = $form['8'];
		$lng = $form['14'];

		$post_location['lat'] = trim( $lat );
		$post_location['lng'] = trim( $lng );

		// save the location
		GeoMashupDB::set_post_location( $id, $post_location );

		// set the custom taxonomies
		wp_set_object_terms( $id, $form['10'], 'countries' );
		wp_set_object_terms( $id, $form['11'], 'continents' );
		wp_set_object_terms( $id, $form['12'], 'cities' );

		// delete all unneeded post meta
		delete_post_meta( $id, 'tj_longitude' );
		delete_post_meta( $id, 'tj_latitude' );
		delete_post_meta( $id, 'tj_continent' );
		delete_post_meta( $id, 'tj_country' );
		delete_post_meta( $id, 'tj_city' );
	}
}
add_action( 'gform_post_submission', 'tj_add_xtra_data' );

What I did here was also integrate GF with the GeoMashup plugin. At the beginning I check for the correct form and in the end I delete all the post meta we don't need any more. All you'd have to do is change the field numbers/permalink id around to fit your needs.

I've actually been thinking about it and I'll probably leave my solution in once you add support for custom taxonomies. I only want my users to add one tag. I guess native support would allow multiple tags...

Now that would be perfect :)

I am also extremely interest about that!!!
