I've read previous questions regarding iframes however i cannot experience how it works. On the Wordpress website I've got a header with hotel booking form, which resides in iframe. Following the user clicks Check availability button, I would like the outcomes to become displayed within the primary content area and whatever is exhibiting as content (for instance About us or E mail us content) I would like this to become changed using the outcomes of the shape and so the user would continue making the booking through primary content area. any suggestions regarding how to do that? and when you can point me to the best direction? it might be really appreciated. thanks.
