AFAIK there is no "OR" in the template syntax.. ;)

You'll have to make do with IF constructs...

But I need an OR clause.
If first_name OR last_name are present I print someting, else no.
How can I solve this problem?

Well.. construct an or by using if / else ?

It is not pretty, but it works.

e.g
if bla1
if bla2
else
print something
end_if
end_if

etc. etc.

Yes - but if only bla2 is true this will not work!

You may build a php function to check your names.

Hence the " etc. etc." in my post.

Of course , The cleaner way would be to add a method to your PHP class.

There was a discussion 2 years ago about the "Template page control with boolean operators" http://silverstripe.org/archive/show/77286#post77286 and http://groups.google.com/group/silverstripe-dev/browse_thread/thread/db752c5de80f3156

I'm still missing the boolean functions inside the Template page control.

Actually you can use <% if First_name || Last_name %>.
