puppet templates follow the erb templating standard.
The puppet documentation contains an example of how to do a simple if statement.
<% if broadcast != "NONE" %>
broadcast <%= broadcast %>
<% end %>
To do an if/else statement, simply add <% else %>
<% if @someclass::someparameter != true %>
bar = 42
<% else %>
bar = 0
<% end %>
-- for dynamic content use: <%= %>
-- for another content use: <% %>
-- eg: <% if 1>2 %>
