Hi!
my problem is understand what kind of object pass to <% control %>.
for example I have this: $data = array('Nome' => $data['nome']);
So I can use :
<% if Nome %> and <% control Nome %>
Why?
the same is valid if I use a name of function? can you explain me?I read http://doc.silverstripe.com/doku.php?id=templates&s=renderwith but is not clear

<% control %> is used to loop over sets of data, or values in 1 DataObject. So any function which returns a 'DataObjectSet' can be used with a control. It is like the foreach() loop in PHP

$data = array('Nome' => $data['nome']); cannot be controlled over as it is only 1 value. So you can check it exists via if Nome. But you would output it in the template as $Nome to get the value
