Show posts by tag based on title, in custom post type

1 Views

On my website I have a directory (custom post type) filled with companies, each have their own listings page. Now at the bottom of the page I want to display all posts which are tagged with the title of that company as shown in the their directory listing page.

For testing, I manually put ‘rennicks’ as the tag. Then added ‘rennicks’ as a tag in about 5 posts, and they all displayed in the listings page fine. But obviously I need it to dynamically retrieve the title and search for tag based on the data in that variable. 

$original_query = $wp_query;
$wp_query = null;
$args=array('tag' => 'rennicks');
$wp_query = new WP_Query( $args );
if ( have_posts() ) :
?>
    <?php
        while (have_posts()) : the_post(); ?>
            <div class="small-12 medium-6 columns content-excerpt">
                <div class="thumbnail medium-6 columns nopm">
                    <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
                </div>
                <div class="content">
                    <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
                    <p><?php //the_excerpt(); ?></p>
                    <div class="related-stats-info">
                        <ul>
                            <!-- <li><?php //the_author(); ?></li> -->
                            <li><i class="fa fa-clock-o"></i> <?php the_date('Y-m-d') ?></li>
                            <li><i class="fa fa-comments"></i> <?php comments_number( '0 comments', '1 comment', '% comments' ); ?></li>
                        </ul>
                    </div>
                </div>
            </div>
        <?php endwhile; ?>
        <div class="clearboth"></div>
<?php
endif;
$wp_query = null;
$wp_query = $original_query;
wp_reset_postdata();

  1. You’ll need to get the post slug, so first I would read that comment and verify that you’re getting the slug. Try maybe doing a var_dump($slug); exit; right after the slug variable to verify you have its correct value. Once you do, try giving this a shot:

    // Get the slug (This is assuming you 
// have the current post in a $post 
// variable. Otherwise, load the post 
// with the post ID like so:
// $post = get_post( $post_id );
$slug = $post->post_name;

// Build args array for query, replacing hyphens with nothing on the slug.
$args = array('tag' => str_replace('-', '', $slug));

// Set wp_query with tag args
$wp_query = new WP_Query( $args );

// If we get result posts from our query...
if ( have_posts() ) :?>
    <?php while (have_posts()) : the_post(); ?>
        <div class="small-12 medium-6 columns content-excerpt">
            <div class="thumbnail medium-6 columns nopm">
                <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
            </div>
            <div class="content">
                <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
