EH

Okay NOW I think I have it working.

        //Add tagged content 
        function posts_by_dir_tag(){
        if (geodir_is_geodir_page()) {    
        
        $post_tag = get_the_title($post->post_title );
        $second_query = new WP_Query( array( 'tag_slug__in' => array( $post_tag) ) );
        }
        // The Loop
        while( $second_query->have_posts() ) : $second_query->the_post();?>
        
        <a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>
        
        <?php
            endwhile;
         wp_reset_postdata();
        }
        
        add_action ('geodir_article_close','posts_by_dir_tag');

I think I actually got it working with:

 function posts_by_dir_tag(){
        if (geodir_is_geodir_page()) {    
        
        $post_title = the_title();
        $second_query = new WP_Query( array( 'tag_slug__in' => array( $post_title ) ) );

        // The Loop
        while( $second_query->have_posts() ) : $second_query->the_post();?>
        
         <a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>
        
        <?php
            endwhile;

        wp_reset_postdata();
        }}
        
        add_action ('geodir_article_close','posts_by_dir_tag');

I was doing it through the CSS on the body class .geodir-page but your way will work too. Thanks!

The only problem with that is then it will show up on sections outside the directory. The directory is only one piece of this site. Can I limit it somehow?

That didn’t seem to work either. Here is the site: http://new.electronichouse.com/location/

Or better yet can someone point me the the direction of the available hooks to use?
