Limit purchases only for some products in WooCommerce

I need something similar as below, but i don't need the warehouse option. I need to block only a few products from being purchased more than once, the other products can be bought more than once. How to include only those product-ID's? add_filter( 'woocommerce_add_to_cart_validation', 'filter_add_to_cart_validation', 10, 4 ); function filter_add_to_cart_validation( $passed, $product_id, $quantity, $variation_id = null ) { $product = wc_get_product( $product_id ); $warehouse = $product->get_attribute('pa_warehouse'); $cart_items = WC()->cart->get_cart(); if ( WC()->cart->is_empty() ) { return $passed; } // Loop through cart items foreach ( WC()->cart->get_cart() as $values ) { // Check if the warehouse is different if ( $warehouse !== $values['data']->get_attribute('pa_warehouse') ) { wc_add_notice( __( 'This product cannot be purchased because...', 'woocommerce' ), 'error' ); return false; } } return $passed; } The code works, but i only need it for a few product id's and i don't know how

From what I understood, you can try this add_filter( 'woocommerce_add_to_cart_validation', 'filter_add_to_cart_validation', 10, 4 ); function filter_add_to_cart_validation( $passed, $product_id, $quantity, $variation_id = null ) { // Define an array of product IDs that should be restricted $restricted_product_ids = array( 1, 2, 3 ); // Check if the current product ID is in the restricted list if ( in_array( $product_id, $restricted_product_ids ) ) { $cart_items = WC()->cart->get_cart(); foreach ( $cart_items as $cart_item_key => $cart_item ) { // Check if the product ID matches one of the restricted products if ( in_array( $cart_item['product_id'], $restricted_product_ids ) ) { wc_add_notice( __( 'This product cannot be purchased more than once.', 'woocommerce' ), 'error' ); return false; // Block the addition } } } return $passed; // Allow the addition to cart for other products } `

add_filter( 'woocommerce_add_to_cart_validation', 'filter_add_to_cart_validation', 10, 4 ); function filter_add_to_cart_validation( $passed, $product_id, $quantity, $variation_id = null ) { // Array of product IDs that should be limited to one purchase $restricted_product_ids = array( 123, 456, 789 ); // Check if the product is in the restricted list if ( in_array( $product_id, $restricted_product_ids ) ) { // Check if the product is already in the cart if ( wc_customer_bought_product( '', get_current_user_id(), $product_id ) ) { wc_add_notice( __( 'This product can only be purchased once.', 'woocommerce' ), 'error' ); return false; } } return $passed; }
