Change the Additional Information Placeholder Text field in WooCommerce
You can change the WooCommerce Additional Information placeholder text field in the checkout page with the woocommerce_checkout_fields filter.
Use it in your themes functions.php file like so…
add_filter( 'woocommerce_checkout_fields' , 'wpb_custom_additional_info' ); // Change placeholder text in Additional Notes function wpb_custom_additional_info( $fields ) { $fields['order']['order_comments']['placeholder'] = 'Add a Shipping address here if different from Billing Address, or any additional notes for delivery'; return $fields; }
Change the text above in the quote ‘Add a Shipping….delivery‘ to what you want.
