Button On/Off Invoice Information

Hi @yourinieuw,

On the invoice must stand BIO-NL01, unless one of the articles.

Sorry if I don’t understand. Where do you need to put BIO-NL01: 1) In a specific place on the invoice, regardless of the products; 2) Next to the products’ name?

To set it on or off with like a button because its different with every invoice.

Do you mean that you’ll use the orders/products with BIO-NL01 to disable/enable the invoice? Please note that after the invoice is generated, an invoice number is created, so previewing the document to check if it stands BIO-NL01, it’s not a good approach. In other words, the best way to automatically disabling the invoice is using this value. This will require a code snippet, but I can write it for you, if this is not beyond the free support.

@yordansoares Ho sorry, unless one of the articles isnt biological. Then Everything on the invoice must be the same, but there cant stand NL-Bio01. So the only change is that on almost every invoice must stand Bio-NL01 but if there is a not biological product, i can delete that

Thanks for providing more details, @yourinieuw!

Where in the invoice you need to display this? Is it just the NL-Bio01 text, with some styling (maybe a heading?), or is this an image seal or something similar?

How can you determine if an order have a product of this type? Does the products have a custom field with this info, it’s in the product name, it’s a category…?

Well @yordansoares, i can’t share a picture but it must stand under the business information. Its text like:

Business name: …
Adress: …
delivery date: ….
NL- Bio01

And well, i can remove it manually but then it must be a button or something to remove it by only that peticular invoice, Because out of the 100 invoices, there will most likely only be 2 or 3 without the NL-Bio01. But it is illegal to show it on the invoice when its incorrect so i need to remove it then. But yeah it is a product attribute in WordPress.

You don’t need to do this manually: I can write a code snippet to add this automatically based on the product attribute you mentioned. Please give me the product attribute name, and I’ll start writing the code snippet for you.

The product attribute name = Biologisch
So when the product does have this attribute its all good,
But when only one product of the whole invoice doesnt have it, then there cant be NL-Bio01 on the invoice. Can you write that?

@yordansoares Sorry i forgot the Tag

Thanks for providing those details, @yourinieuw!

Try adding this code snippet to your site, to display ‘NL-Bio01’ after the billing address, if all the products has the ‘Biologisch’ attribute:

/**
 * WooCommerce PDF Invoices & Packing Slips
 * Print 'NL-Bio01' after billing address if all the products has the 'Biologisch'
 */
add_action( 'wpo_wcpdf_after_billing_address', function( $document_type, $order ) {
	if( $document_type == 'invoice' ) {
		foreach ( $order->get_items() as $item_id => $item ) {
			if ( ( $product = $item->get_product() ) && is_callable( array( $product, 'get_attribute' ) ) ) {
				if ( empty( $product->get_attribute( 'Biologisch' ) ) ) {
					return;
				}
			}
		}
		echo '<div>NL-Bio01</div>';
	}
}, 10, 3 );

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters

@yordansoares Thanks!

I’m happy to help: Let me know if it worked! ??
