title: Insert a dynamic value into text string on specific WooCommerce email template
body: <p>I am modifying one of the WooCommerce email templates and adding text based on what payment method is used:</p>
  <pre><code>if ( 'bacs' == $order-&gt;get_payment_method() ){
      echo &quot;We are awaiting payment&quot; ;
      echo $order-&gt;get_order_number();
  }
  elseif ( 'paypal' == $order-&gt;get_payment_method() )  {
      echo &quot;Text2&quot;;
  }
  else {
      echo &quot;Text3;
  }
  </code></pre>
  <p>I need to add the order ID into the first text (for BACS), so that it would display:</p>
  <p>We are awaiting payment. Order reference: 1234 (your order number).</p>
  <p>How can I add the order number into my plain text?</p>
