I want to display related products based on Custom taxonomy. Is there a way to force related products to be displayed based on Custom taxonomy?
add_filter( 'woocommerce_output_related_products_args', 'prfx_change_related_products_count' );
function prfx_change_related_products_count( $args ) {
// Current post as global
global $post;
$terms = get_the_terms( $post->ID, 'your_custom_taxonomy' );
// Empty array
$ids = array();
foreach ( $terms as $term ) {
array_push($ids, $term->term_id);
}
$args['tax_query'] = array(
array(
'taxonomy' => 'your_custom_taxonomy',
'terms' => $ids,
'field' => 'term_id',
'include_children' => true,
'operator' => 'IN'
)
);
return $args;
}

I got a shortcode to print out the brand name connected to the current page:
add_shortcode( 'MARKE', 'marke_shortcode' );
function marke_shortcode() {
$terms = array(
'post_type' => 'fahrzeuge',
'taxonomy' => 'marken',
'hide_empty' => false,
'fields' => 'ids'
);
if( is_tax('marken') ) {
$terms['tax_query'] = array(
array(
'taxonomy' => 'marken',
'field' => 'term_id',
'terms' => (array) get_queried_object_id(),
)
);
}
$posts = get_posts( $terms );
if( ! empty( $posts ) )
return get_field( 'marken', $posts[0] );
return '0';
}
Unfortunately the code isn't working.
What I try to achieve is that the brand name, e.g. Tesla is printed out with the shortcode [MARKE] on both type of pages:
https://moinmobility.de/marken/tesla/
https://moinmobility.de/marken/tesla/model-3/
I tried a lot of code chunks and always if the brand name was printed correctly on the parent page, the child one was wrong.
I'm trying to display products in Woocommerce Related Products according to custom taxonomies, created with CPT UI. I tried this :
add_filter( 'woocommerce_output_related_products_args', 'prfx_change_related_products_count' );
function prfx_change_related_products_count( $args ) {
// Current post as global
global $post;
$terms = get_the_terms( $post->ID, 'artists' );
// Empty array
$ids = array();
foreach ( $terms as $term ) {
array_push($ids, $term->term_id);
}
$args['tax_query'] = array(
array(
'taxonomy' => 'artists',
'terms' => $ids,
'field' => 'term_id',
'include_children' => true,
'operator' => 'IN'
)
);
return $args;
}
The code comes from this previous post Display Woocommerce Related Products By Custom Taxonomy but it doesn't seem to work.
Ideally i would like 6 products to be displayed according to 4 custom taxonomies:
artists > labels > genre > formats.
For example if there are only 2 products from the same artists then the rest would be randomly chosen from labels and so on.
Please don't judge this question harshly.
I have tried showing in Related Products only products from the same category in which the user is viewing the product right now, and by product tags (if applicable). But nothing has changed for me.
It turns out that WooCommerce already displays recommended products from the same category and by the same tags by default.
Below you will find the answer to this question. But let this code remain here simply as a sample code.
function related_products_by_current_category( $related_posts, $product, $args ) {
global $post;
$cat = $product->get_category_ids();
$tags = wp_get_post_terms( $post->ID, "product_tag" );
foreach ( $tags as $tag ) {
$tags_array[] .= $tag->term_id;
}
$related_posts = new WP_Query(
array(
'orderby' => 'rand',
'posts_per_page' => 4,
'post__not_in' => array($post->ID),
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'product_cat',
'field' => 'id',
'terms' => $cat
)
array(
'taxonomy' => 'product_tag',
'field' => 'id',
'terms' => $tags_array
)
)
)
);
return $related_posts;
}
add_filter( 'woocommerce_related_products', 'related_products_by_current_category', 999, 3 );
WooCommerce already fetches related products based on the same terms( categories and tags )
If you want to get more control over the related products by categories and tags, you can use these two filters
apply_filters( 'woocommerce_get_related_product_cat_terms', wc_get_product_term_ids( $product_id, 'product_cat' ), $product_id );
apply_filters( 'woocommerce_get_related_product_tag_terms', wc_get_product_term_ids( $product_id, 'product_tag' ), $product_id );
These filters return the current product categories | tags IDs which will be used to get related products. you can use these filters to return specific terms IDs based on the given product ID .
In my wooCommerce platform, I do not want to show products that do not have a category selected. I mean which products categories is empty that's products are not display in my site.
Is it any way to do that?
There are different ways to retrieve products, and if you want to exclude products which have no category assigned to from everywhere in your site, then you will need to address all of them.
WP_Query
You can hook into the pre_get_posts action and modify the tax_query arg in order to exclude products in the uncategorized product category (only when the query post type is product). I'm in fact assuming uncategorized being the slug of the default product category (you will need to amend it to your specific configuration). E.g.:
function remove_uncategorized_products( $query ) {
if ( is_admin() ) {
return;
}
if ( 'product' !== $query->get( 'post_type' ) ) {
return;
}
$tax_query = (array) $query->get( 'tax_query' );
$tax_query[] = array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => array( 'uncategorized' ),
'operator' => 'NOT IN',
);
$query->set( 'tax_query', $tax_query );
}
add_action( 'pre_get_posts', 'remove_uncategorized_products' );
WC_Query
Similar to WP_Query, you can hook into the woocommerce_product_query action to modify the query. E.g.:
function custom_pre_get_posts_query( $q ) {
$tax_query = (array) $q->get( 'tax_query' );
$tax_query[] = array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => array( 'uncategorized' ),
'operator' => 'NOT IN'
);
$q->set( 'tax_query', $tax_query );
}
add_action( 'woocommerce_product_query', 'custom_pre_get_posts_query' );
WC_Product_Query (used by wc_get_products)
In this case, we can't change the query args to exclude certain product categories. We can instead loop through each product returned by the query and check its category. E.g.:
function filter_uncategorized_products_out( $results, $args ) {
$products = array();
foreach ( $results as $p ) {
$is_uncategorized = false;
$terms = get_the_terms( $p->get_id(), 'product_cat' );
foreach ( $terms as $term ) {
if ( 'uncategorized' === $term->slug ) {
$is_uncategorized = true;
}
}
if ( ! $is_uncategorized ) {
$products[] = $p;
}
}
return $products;
}
add_filter( 'woocommerce_product_object_query', 'filter_uncategorized_products_out', 10, 2 );
Please note that there are other ways to retrieve products (for example using $wpdb directly). You might need to check all the pages of your site to see if you have covered them all.
I want to display particular authors' products on the shop page.
but I don't know how can I do it I tried to do using the below code.
/**
* Exclude products from a particular category on the shop page
*/
function custom_pre_get_posts_query($q)
{
$user_id = 44;
$args = array(
'post_type' => 'product',
'posts_per_page' => -1,
'fields' => 'ids',
'author' => $user_id
);
$loop = new WP_Query($args);
echo '<pre>';
print_r($loop->posts);
echo '</pre>';
$tax_query = (array) $q->get('tax_query');
$tax_query[] = array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => array('camisetas'), // Don't display products in the clothing category on the shop page.
'operator' => 'NOT IN'
);
$q->set('tax_query', $tax_query);
}
add_action('woocommerce_product_query', 'custom_pre_get_posts_query');
now I get all products of a particular user id in my case it 44.
but I don't know how to implement it in woo-commerce tax query.
You can pass author to query.
function custom_pre_get_posts_query( $q ){
if( is_admin() ) return;
$user_id = 44;
$q->set( 'author', $user_id );
}
add_action( 'woocommerce_product_query', 'custom_pre_get_posts_query', 10, 1 );
