Deactivate invoice for several products

Hi all,

I was following the steps shown in this topic, I want to exclude several products from invoice generation.

I used the following code (in code snippet plugin) to do that, but this code worked one time (idk why, I used it, then I disabled the plugin for 5 mins, then I activated it again).

add_filter( 'wpo_wcpdf_custom_attachment_condition', 'wpo_wcpdf_exclude_products', 100, 4 );
function wpo_wcpdf_exclude_products( $condition, $order, $status, $template_type ) {
    // only apply check on invoices
    if ($template_type != 'invoice') {
        return $condition;
    }

    // define product IDs which shouldn't get an invoice here
    $no_invoice_products = array( 101, 102 );

    // loop through order items and cancel attachment if one of the products present
    $items = $order->get_items();
    foreach ($items as $item_id => $item) {
    	if (in_array($item->get_product_id(), $no_invoice_products)) {
	        // matching product, don't attach invoice
    		return false;
    	}
    }

    // if we got here, there were no matching products
    return $condition;
}

What should I do? I need a code that disables several product IDs from generating invoices

Thanks for the support!

EDIT: I was wondering if…
Perhaps it is better to act in the reverse way in my case: enable the generation of invoices only for specific products (because there are so many products to be excluded)

EDIT2: The products are subcriptions that renew every month/year
EDIT3: I recreated the code snipper and now… he worked! … I keep this topic open asking what I wrote in “EDIT:”, if possible…
