show related product base on last category �

Woodmart’s related products widget currently uses the first product category, which can result in irrelevant item suggestions. I would like to propose the following enhancements: 1. Use the deepest (latest) category assigned to the product; fallback to parent category. 2. Include price range matching (e.g. ±20% around current product price or configurable). 3. Add a toggle control to: - Show only in‑stock products - Or include out‑of‑stock/backorder items 4. Allow per‑product or global enable/disable via Customizer or product‑level metabox. 5. Provide developer filters/hooks such as: - `woodmart_related_query_args($args, $product_id)` - `woodmart_show_related_section($show, $product_id)` 6. Implement caching for query results (e.g. via `transient_set/get`) for performance. 7. Ensure compatibility with WPML, SEO plugins, and related‑product plugins like WebToffee :contentReference[oaicite:22]{index=22}. **Benefits:** - More contextually relevant suggestions → higher conversion rates - Flexible configuration and smarter UX - Lightweight queries with performance safety - Values developer customization and compatibility with popular plugins Technical Details Category detection: $cats = wp_get_post_terms($product_id, 'product_cat'); $deepest = select_deepest($cats); if (!$deepest) $deepest = fallback($cats); Price filtering: $price = get_post_meta($product_id, '_price', true); $min = $price * (1 - $price_delta); $max = $price * (1 + $price_delta); $args['meta_query'][] = ['key'=>'_price','value'=>[$min,$max],'compare'=>'BETWEEN','type'=>'NUMERIC']; Stock filtering: if ($instock_only) { $args['meta_query'][] = ['key'=>'_stock_status','value'=>'instock']; } Extensible hooks: $args = apply_filters('woodmart_related_query_args', $args, $product_id); $show = apply_filters('woodmart_show_related_section', true, $product_id); Caching example: $transient_key = 'wd_related_' . $product_id; $related = get_transient($transient_key); if (!$related) { $related = new WP_Query($args); set_transient($transient_key, $related, HOUR_IN_SECONDS); }
