    Hello, GP Team!

    I’m currently using GP Hooks and WP Show Posts Pro to display related posts by Tags, however, there are a few Tags that only have 1 post, which makes the code I’m using return the following message:

    “Sorry, no more posts to show”

    I was wondering if it was possible to make it so that if there are no more posts in that Tag, to make it show posts in that Category instead.

    I’m using a Hook code found in another GP thread. Here it is:

    <div class="wpsp-related-posts1  grid-container">
    	<h2>Related Posts</h2>
    <?php    
    if ( is_single() ) {
            $tags =  get_the_tags();
            $tags_list = [];
            foreach ($tags as $tag)
                $tags_list[] = $tag->slug;
            $tag_string = implode( ', ', $tags_list);
        } else {
            $tag_string = get_tag( get_query_var( 'tag' ) );
        }
    
        $list = get_page_by_title( 'related', 'OBJECT', 'wp_show_posts' );
        wpsp_display( $list->ID, 'tax_term="' . $tag_string . '"' );
        ?>
    </div>

    Thanks in advance 🙂

    Hi there,

    In your list settings, is the taxonomy set to post_tag?

    We may be able to adjust the settings a bit in the PHP.

    Let me know 🙂

    Hey, Tombeans!

    Yes, the taxonomy in my list settings is set to post_tag. 🙂

    Ok, let’s try this:

    <div class="wpsp-related-posts1  grid-container">
    	<h2>Related Posts</h2>
    <?php
        $tax = 'post_tag';
    
        if ( is_single() ) {
            $tags =  get_the_tags();
            $tags_list = [];
            $tag_ids = [];
            foreach ($tags as $tag) {
                $tags_list[] = $tag->slug;
                $tag_ids[] = $tag->term_id;
            }
    
            $args = array(
                'numberposts' => 5,
                'tag__in' => $tag_ids,
                'post__not_in' => array( get_the_ID() )
            );
    
            $posts = get_posts( $args );
    
            if ( ! empty( $posts ) ) {
                $tax_term = implode( ', ', $tags_list);
            } else {
                $cats =  get_the_category();
                $text_term = $cats[0]->slug;
                $tax = 'category';
            }
        }
    
        $list = get_page_by_title( 'related', 'OBJECT', 'wp_show_posts' );
        wpsp_display( $list->ID, 'taxonomy=' . $tax . '&tax_term=' . $tax_term );
        ?>
    </div>

    Hey, Tom!

    Nope, it’s not working 🙂

    That’s a shame. Can you try the updated code?: https://generatepress.com/forums/topic/related-posts-by-tags-and-categories-wp-show-posts-pro-gp-hooks/#post-1281194

    If that doesn’t work we’ll likely need to add some debugging stuff in there to see what’s going on.

    Hey, Tom the bomb!

    I tried the updated one, but unfortunately, it didn’t work. I went ahead and deactivated Autoptimize to see if it was maybe some setting there, but nothing changed. 🙁 🙂

    Are the tags still working if they exist?

    #1284293
    Christian

    Yes, with the updated code, if the Tag has more than 1 blog post, it still works and shows the related posts.

    Not sure if that’s what you meant by “exist?” 🙂

    Ok, let’s debug:

    <div class="wpsp-related-posts1  grid-container">
    	<h2>Related Posts</h2>
    <?php
        $tax = 'post_tag';
    
        if ( is_single() ) {
            $tags =  get_the_tags();
            $tags_list = [];
            foreach ($tags as $tag) {
                $tags_list[] = $tag->slug;
            }
            
            var_dump($tags_list);
    
            if ( $tags_list ) {
                $tax_term = implode( ', ', $tags_list);
            } else {
                $cats =  get_the_category();
                $text_term = $cats[0]->slug;
                $tax = 'category';
            }
        } else {
            $tax_term = get_tag( get_query_var( 'tag' ) );
    
            if ( ! $tax_term ) {
                $cat = get_category( get_query_var( 'cat' ) );
    
                if ( $cat ) {
                    $text_term = $cats[0]->slug;
                    $tax = 'category';
                }
            }
        }
    
        $list = get_page_by_title( 'related', 'OBJECT', 'wp_show_posts' );
        wpsp_display( $list->ID, 'taxonomy=' . $tax . '&tax_term=' . $tax_term );
        ?>
    </div>

    What outputs on a post that should fall back to the category?

    #1284635

    Here’s what outputs on posts that should fall back to the category:

    array(1) { [0]=> string(21) “nutrition-supplements” }
    Sorry, no posts were found.

    What gets output here when no posts exist?

    #1286049
    Christian

    This is what gets output when no posts exist:

    array(1) { [0]=> object(WP_Post)#2457 (24) { [“ID”]=> int(5621) [“post_author”]=> string(1) “3” [“post_date”]=> string(19) “2019-09-22 15:21:40” [“post_date_gmt”]=> string(19) “2019-09-22 19:21:40” [“post_content”]=> string(10243)

    Plus, the whole current blog post. 🙂
