Variable text on top of Invoice

Hi @panconpescao,

Try the following code snippet:

/**
 * PDF Invoices & Packing Slips:
 * Show a custom text after the document label for certaing shipping method IDs
 */
add_action( 'wpo_wcpdf_after_document_label', function( $document_type, $order ) {
  if ( $document_type == 'invoice' ) {
	// Check shipping methods
	if ( ! empty( $shipping_methods = $order->get_shipping_methods() ) ) {
		$first_method = array_shift( $shipping_methods );
		$shipping_method_id = $first_method->get_method_id();
	}
	
	if ( $shipping_method_id == 'first_shipping_id' ) {
		$custom_text = 'bluexpress';
	} elseif ( $shipping_method_id == 'second_shipping_id' ) {
		$custom_text = 'starken';
	}
	if ( $custom_text ) {
		echo "<div style='margin: -10pt 0 10pt 0'>$custom_text</div>";
	}
  }
}, 10, 2 );

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

Please note that you have to replace first_shipping_id and second_shipping_id with the actual shipping method IDs.

Hi, i tried the snippet but it didn’t work. i have a question: how can i put multiple shipping IDs?

For starken i need 14, 11, 12, 24
For bluexpress i need 15, 13, 23

Hi @panconpescao,

With the following code snippet, you should be able to set different IDs per case, as you want:

/**
 * PDF Invoices & Packing Slips:
 * Show a custom text after the document label for certaing shipping method IDs
 */
add_action( 'wpo_wcpdf_after_document_label', function( $document_type, $order ) {
    if ( $document_type == 'invoice' ) {
        // Check shipping methods
        if ( ! empty( $shipping_methods = $order->get_shipping_methods() ) ) {
            $first_method = array_shift( $shipping_methods );
            $shipping_method_id = $first_method->get_method_id();
        }
        
        if ( in_array( $shipping_method_id, [ 15, 13, 23 ] ) ) {
            $custom_text = 'bluexpress';
        } elseif ( in_array( $shipping_method_id, [ 14, 11, 12, 24 ] )  ) {
            $custom_text = 'starken';
        }
        if ( $custom_text ) {
            echo "<div style='margin: -10pt 0 10pt 0'>$custom_text</div>";
        }
    }
}, 10, 2 );

Please note that I have used the numbers you have provided, though in my experience, shipping IDs are usually formatted using slug names like flat_rate, local_pickup, free_shipping, etc. Therefore, please double-check that you update the code snippet using the actual shipping IDs.
