I have a page taht take data from external database about product. This page show product's photo, some row of text adn a 'detail' button (when I ckick on this button I show all product characteristic).
I need a widget to show randomly one of this product every week. (only product name and a link to that product page)
Can I use random content widget?or something else?
Assuming your product class name is Product and the fields you want are Title and Link...
Page_Controller extends Content_Controller
return DataObject::get_one("Product",null, false, "RAND()");
and on any page
<% control RandomContent %>
<% end_control %>
