PDF Invoice on specific product category only

Hi @mad2kx,

Try by adding this code snippet to your site in order to achieve what you want to:

/**
 * Enable invoice just for specific product categories
 */
add_filter( 'wpo_wcpdf_document_is_allowed', function( $condition, $document ) {	
	if ( $document->type == 'invoice' ) {
		if ( $document->exists() ) {
			return $condition;
		}
		$condition = false;
		if ( $order = $document->order ) {
			//Set categories here (comma separated)
			$not_allowed_cats = array( 'accessories', 'music' );

			$order_cats = array();
			//Get order categories
			foreach ( $order->get_items() as $item_id => $item ) {
				// get categories for item, requires product
				if ( $product = $item->get_product() ) {
					$id = $product->get_parent_id() ? $product->get_parent_id() : $product->get_id();
					$terms = get_the_terms( $id, 'product_cat' );

					if ( empty( $terms ) ) {
						continue;
					} else {
						foreach ( $terms as $key => $term ) {
							$order_cats[$term->term_id] = $term->slug;
						}
					}
				}
			}

			// get array of category matches
			$cat_matches = array_intersect( $not_allowed_cats, $order_cats );
			if ( count( $cat_matches ) > 0 ) {
				return true; // if there is 1 or more matches: allow invoice
			}
		}
	}
	return $condition;
}, 10, 2 );

Let me know if it worked! ??

@yordansoares thanks for your fast response. So I just need to replace your $not_allowed_cats = array( 'accessories', 'music' ); with my category that I want to enable invoices for?

That’s right! I used accessories and music as examples, but you need to put your actual category slugs there.

@yordansoares awesome thank you so much it’s working.

I’m glad to hear that it worked!

If you don’t mind and have the time, do you think you could leave us a review?

Thanks in advance and all the best with your store!
