在Woocommerce单品页面上排除特定的产品类别

Question

I'm trying to exclude some categories from being displayed on the WooCommerce product page.

Example: if in a single product page I have "Categories: Cat1, Cat"2", I want that only Cat1 will be displayed.

I tried editing the meta.php in the single-product template. I created a new function:

$categories = $product->get_category_ids();
$categoriesToRemove = array(53,76,77,78); // my ids to exclude
foreach ( $categoriesToRemove as $categoryKey => $category) {
    if (($key = array_search($category, $categories)) !== false) {
        unset($categories[$key]);
    }
}
$categoriesNeeded = $categories;

Then I have the echo from WooCommerce:

echo wc_get_product_category_list( $product->get_id(), ', ', '<span class="posted_in">' . _n( 'Category:', 'Categories:', count($categories), 'woocommerce' ) . ' ', '</span>' );

But it still shows the same categories. The strange thing is that when I do a var_dump($categories) it shows the correct thing.

You should try this custom function hooked in get_the_terms filter hook, that will exclude specific product categories to be displayed on single product pages:

add_filter( 'get_the_terms', 'custom_product_cat_terms', 20, 3 );
function custom_product_cat_terms( $terms, $post_id, $taxonomy ){
    // HERE below define your excluded product categories Term IDs in this array
    $category_ids = array( 53,76,77,78 );

    if( ! is_product() ) // Only single product pages
        return $terms;

    if( $taxonomy != 'product_cat' ) // Only product categories custom taxonomy
        return $terms;

    foreach( $terms as $key => $term ){
        if( in_array( $term->term_id, $category_ids ) ){
            unset($terms[$key]); // If term is found we remove it
        }
    }
    return $terms;
}

Code goes in function.php file of your active child theme (or active theme).

Tested and works.
