[Resolved] Related Posts by Tags and Categories [WP Show Posts Pro + GP Hooks]

[Tom]

Adjusted the code above to exclude the current post: https://generatepress.com/forums/topic/related-posts-by-tags-and-categories-wp-show-posts-pro-gp-hooks/#post-1285989

Which post has this ID?: 5621

Does it have the tag you’re trying to find related posts using?

[Christian]

Yes, post with ID: 5621 has the tag I’m trying to find related posts (but since there are no related posts, it should fallback to posts from the same Category instead).

The updated code you sent seems to be pulling blog posts now, but from all Categories. It also outputs this before the posts it pulls:

array(0) { }

[Tom]

Cool, that’s progress.

More testing: https://generatepress.com/forums/topic/related-posts-by-tags-and-categories-wp-show-posts-pro-gp-hooks/#post-1285989

What does that output?

[Christian]

It outputs this:

string(8) “category” NULL

Still followed by blog posts from all Categories. 🙂

[Tom]

Does the post have a category? If it’s outputting “NULL”, it means it’s not finding a category for the current post.

[Christian]

Yeap, it has a Category. Just double-checked to make sure.

[Tom]

K, let’s keep going. We will get this… lol

What does this tell you? https://generatepress.com/forums/topic/related-posts-by-tags-and-categories-wp-show-posts-pro-gp-hooks/#post-1285989

[Christian]

This one output quite a bit more:

array(1) { [0]=> object(WP_Term)#2437 (16) { [“term_id”]=> int(596) [“name”]=> string(11) “Weight Loss” [“slug”]=> string(11) “weight-loss” [“term_group”]=> int(0) [“term_taxonomy_id”]=> int(596) [“taxonomy”]=> string(8) “category” [“description”]=> string(106) “Research-based weight loss articles to help you create a clear path toward your health and wellness goals.” [“parent”]=> int(0) [“count”]=> int(87) [“filter”]=> string(3) “raw” [“cat_ID”]=> int(596) [“category_count”]=> int(87) [“category_description”]=> string(106) “Research-based weight loss articles to help you create a clear path toward your health and wellness goals.” [“cat_name”]=> string(11) “Weight Loss” [“category_nicename”]=> string(11) “weight-loss” [“category_parent”]=> int(0) } }

[Tom]

Ok, so that means it should be querying posts that:

1. Have the taxonomy: category
2. Have the category weight-loss

[Christian]

Correct! 🙂

[Tom]

Hmm, I’m not sure what’s up then. The query itself should be fine. I suppose we can debug the query itself.

First, add the list:

<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>

Then add this filter:

add_filter( 'wp_show_posts_shortcode_args', function( $args ) {
    var_dump($args);
    return $args;
} );

Can you share the result of that above the list?

[Christian]

Hey, Tom!

Here’s what the last code you sent outputs:

It shows posts from all Categories followed by

add_filter( ‘wp_show_posts_shortcode_args’, function( $args ) { var_dump($args); return $args; } );

But don’t worry about it, I’m okay with just leaving it as is! I feel like I’m abusing your support.

Thank you so much, Tom! 🙂 you’re the bestest.

[Tom]

Did you add that filter using one of these methods?: https://docs.generatepress.com/article/adding-php/

No worries! Here if you need me.

[Christian]

Whoops, my bad.

After adding it to the PHP, it outputs blog posts from all Categories, nothing else.

[Tom]

No debug info displays at all?
