Hello Zsolt,

You can insert PHP code in an HTML Code Object within WebSite X5:

Alternatively you can use the 'Expert' tab in any page's properties to include code before the header, or in the head or body as necessary:

You can also insert custom HTML code in the shopping cart to create 'Pay Now' buttons:

Kind regards,
