Use meta_query to get title of associated post

2 Views

I have two post types that I’ve associated in one direction by assigning Post A as a custom meta field of Post B. I need to search based on the titles of Post A and return the associated Post B results. This feels a little tricky.

Normally I can display titles from Post A like so:

        $post = get_post($post_id);
        $author_post_id = get_post_meta($post->ID, 'custom_author', true);
        $post_object = get_post( $author_post_id );
        echo get_the_title($post_object);

And I believe I’m using meta_query correctly to search Post B: 

        $args = array(
            'post_type' => 'journal_entry',
            'meta_query' => array(
                array(
                    'key' => 'custom_author',
                    'compare' => 'LIKE'
                )
            )
         );
        $query = new WP_Query( $args );
        if ( $query->have_posts() ): while ( $query->have_posts() ) : $query->the_post();
            // Loop
        endwhile; endif;
        // Reset post data
        wp_reset_postdata();

But I think I need to shoehorn get_the_title into my meta_query value. I think. I’m a little turned around. Am I on the correct path?

  1. Try setting $title_search = get_the_title($post_object); and then using it in your query as 'value' => $title_search:

    $args = array(
    'post_type' => 'journal_entry',
    'meta_query' => array(
        array(
            'key' => 'custom_author',
            'compare' => 'LIKE',
            'value' => $title_search
        )
    )
 );
