I need to hide products on my shop which are included in grouped products. I wrote function which does it:
add_filter('woof_products_query', 'woof_hide_grouped_products_from_category', 100);
function woof_hide_grouped_products_from_category($query_vars)
{
$taxonomy = $query_vars['tax_query'][0]['taxonomy'];
$term_slug = $query_vars['tax_query'][0]['terms'][0];
$term = get_term_by('slug', $term_slug, $taxonomy);
$term_id = $term ? $term->term_id : 0;
if (isset($taxonomy) && $taxonomy && isset($term_id) && $term_id) {
$child_product_ids = get_grouped_children_ids($term_id, $taxonomy);
if (!empty($child_product_ids)) {
$query_vars['post__not_in'] = $child_product_ids;
}
}
return $query_vars;
}All is good, products are not visible in products list. But terms of taxonomies which include only those products still are present in filter.
How can I hide from the filter taxonomy terms that only contain hidden products that are part of group products?
Hello
You can edit requests for counting - woof_dynamic_count_attr ( https://share.pluginus.net/image/i20230814141026.png )
Thank you! It works. But the plugin starts to work very slowly, because for each term there is a recalculation with post__not_in. And if I do not change the query, but exclude unnecessary elements already after receiving the result? Is there any hook for this case? And will it make the filter faster?
Hello
Unfortunately not, because in any case, a dynamic recalculation will be needed.
Maybe there are woocommerce hooks, but unfortunately my filter plugin doesn't have such a hook
Understand. Thank you very much for the answers!
Cancel post__not_in โ he thinks for a very long time. I came up with another option, maybe someone will find it useful.
So, instead of searching for products that are part of a group product for each term separately, we store a special post_meta field for those products. We write the following synchronization when saving any product:
// Synchronize 'grouped_child' post_metas in products on product save
add_action('save_post', 'synchronize_grouped_child_post_meta', 10, 3);
function synchronize_grouped_child_post_meta($post_id, $post, $update)
{
$args = array(
'post_type' => 'product',
'posts_per_page' => -1,
);
$products = get_posts($args);
$grouped_products_ids = [];
$simple_products_ids = [];
foreach ($products as $product) {
$parent_grouped_id = get_parent_grouped_id($product->ID);
if ($parent_grouped_id) {
$grouped_products_ids[] = $product->ID;
} else {
$simple_products_ids[] = $product->ID;
}
}
foreach ($grouped_products_ids as $product_id) {
if (!get_post_meta($product_id, 'grouped_child', true)) {
update_post_meta($product_id, 'grouped_child', 'yes');
}
}
foreach ($simple_products_ids as $product_id) {
if (get_post_meta($product_id, 'grouped_child', true)) {
delete_post_meta($product_id, 'grouped_child');
}
}
}The get_parent_grouped_id function looks like this:
function get_parent_grouped_id($children_id)
{
global $wpdb;
$results = $wpdb->get_col("SELECT post_id FROM {$wpdb->prefix}postmeta
WHERE meta_key = '_children' AND meta_value LIKE '%$children_id%'");
// Will only return one product Id or false if there is zero or many
return sizeof($results) == 1 ? reset($results) : false;
}Now, instead of a complex condition to search for post__not_in, we add a simple meta-query to all three required hooks:
// Hide simple products from category page if they are in grouped product
add_filter('woocommerce_product_query', 'hide_grouped_products_from_category', 99999);
function hide_grouped_products_from_category($query)
{
if (
!is_admin() && $query->is_main_query() && $query->is_archive()
) {
$meta_query = [
[
'key' => 'grouped_child',
'compare' => 'not exists',
],
];
$query->set('meta_query', $meta_query);
}
}
add_filter('woof_products_query', 'woof_hide_grouped_products_from_category', 100);
add_filter('woof_dynamic_count_attr', 'woof_hide_grouped_products_from_category', 10);
function woof_hide_grouped_products_from_category($query_vars)
{
$query_vars['meta_query'] = [
[
'key' => 'grouped_child',
'compare' => 'not exists',
],
];
return $query_vars;
}It works! Thanks for the tips that led to the correct decision!
