💎 PREMIUM: Support/topic/most popular posts in current category

I currently use WordPress Popular Posts across my site.

On posts, I would like to be able to filter the popular posts to the current category(s).

Is this something that I can do via the shortcode or would I need to write some custom PHP to achieve this? If I need to write custom code does that then mean I need to change from using the [wpp] shortcode to create a new shortcode or does the custom PHP overwrite the default settings of [wpp]?

The page I need help with: [log in to see the link]

You’d need some custom PHP code for that, yes, as the shortcode doesn’t have a feature that allows it to automatically detect the category of the current post.

We can use the shortcode_atts_{shortcode} filter hook to dynamically set the cat parameter for the [wpp] shortcode, like so for example:

/**
 * Filters popular posts list by current post's category ID.
 *
 * @param  array  $out  The output array of shortcode attributes.
 * @return array  $out  The (modified) output array of shortcode attributes.
 */
function wp_1356_filter_popular_posts_by_current_post_category( $out ) {
    if ( is_single() ) {
        $current_post_ID = get_queried_object_id();

        // Get the first category
        $categories = get_the_category( $current_post_ID );

        if ( ! empty( $categories ) ) {
            $category_ID = $categories[0]->term_id;
            $out['cat'] = $category_ID;
        }
    }

    return $out;
}
add_filter( 'shortcode_atts_wpp', 'wp_1356_filter_popular_posts_by_current_post_category', 1, 1 );
