Enhance classipress loop
Hi I am looking to enhance the classipress loop so that I can set a location to create local versions of my site. This would then mean that after the user has selected a location all searches/browsing and home page ads will be displayed but filtered by this location.
At the moment I think this can be done using the posts_where filter but I cannot see how I can break into the classipress loop so that it joins on the wp_postmeta table.
Has anyone done something similar to this that would be happy to lend a hand.
