The conditional tag is_product_category()
only target product category archive pages. Instead you can use WordPress conditional function has_term()
.
There is 2 ways to avoid specific products being added to cart for no logged user…
1) Using Add to cart validation hook:
// Avoid add to cart conditionally
add_filter( 'woocommerce_add_to_cart_validation', 'avoid_add_to_cart_conditionally', 20, 3 );
function avoid_add_to_cart_conditionally( $passed, $product_id, $quantity) {
// HERE your product categories (can be IDs, slugs or names terms)
$terms = array( 'gekoelde-bier', 'bierkoerier');
if( has_terms( $terms, 'product_cat', $product_id ) && ! is_user_logged_in() ){
// Displaying a custom notice (optional)
wc_add_notice( __('Only logged in users are allowed to purchase this item. Please register.'), 'error' );
$passed = false;
}
return $passed;
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
2) Using is_purchasable
product property (It will remove add to cart button):
add_filter('woocommerce_is_purchasable','conditional_purchasable_products', 20, 2);
function conditional_purchasable_products( $is_purchasable, $product ) {
// HERE your product categories (can be IDs, slugs or names terms)
$terms = array( 'gekoelde-bier', 'bierkoerier');
$product_id = $product->get_id(); // The product ID
if( has_terms( $terms, 'product_cat', $product_id ) && ! is_user_logged_in() ){
$is_purchasable = false;
}
return $is_purchasable;
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
Targeting the parent product category terms too.
You will use the following custom conditional function to replace has_term()
Wordpress function:
// Custom conditional function that handle parent product categories too
function has_product_categories( $categories, $product_id = 0 ) {
$parent_term_ids = $categories_ids = array(); // Initializing
$taxonomy = 'product_cat';
$product_id = $product_id == 0 ? get_the_id() : $product_id;
if( is_string( $categories ) ) {
$categories = (array) $categories; // Convert string to array
}
// Convert categories term names and slugs to categories term ids
foreach ( $categories as $category ){
$result = (array) term_exists( $category, $taxonomy );
if ( ! empty( $result ) ) {
$categories_ids[] = reset($result);
}
}
// Loop through the current product category terms to get only parent main category term
foreach( get_the_terms( $product_id, $taxonomy ) as $term ){
if( $term->parent > 0 ){
$parent_term_ids[] = $term->parent; // Set the parent product category
$parent_term_ids[] = $term->term_id; // (and the child)
} else {
$parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
}
}
return array_intersect( $categories_ids, array_unique($parent_term_ids) ) ? true : false;
}
Then for both hooked functions, you will replace the following line :
if( has_terms( $terms, 'product_cat', $product_id ) && ! is_user_logged_in() ){
By this line:
if( has_product_categories( $terms, $product_id ) && ! is_user_logged_in() ){
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
