I am trying the following in my templates:

         <% if Property1 or Property2 or Property3 %>
         <% end_if %>

but it seems to crash the site. Any idea for an unlimited or conditional statement ?

or here -->

or "same as php"

Hope this helps!

Thank you for pointing that documentation page out.

I guess I can always do nested conditional statements or use a CheckboxSetField.

However, it seems that what is possible in php ( is not necessarily possible with Silverstripe. This is cumbersome in my case because I would like to check if many variables exist at once.

I get a blank page in my templates with:

<% if Checkbox1 || Checkbox2 || Checkbox3 %>
<% end_if %>

With Checkbox1, Checkbox2 and Checkbox3 each as Boolean CheckboxField.

I also get a blank page with:
<% if Text1 = Hello && Text2 = Hello %>
<% end_if %>

With Text1 and Text2 as Varchar.

This is with Mamp and SS 2.4.0.

Hi tonito,

It has been mentioned many times that templates should be simple and readable.

Maybe defining a PHP function like...

function AnyOfThreeSettingsTrue()
return ($this->Setting1 || $this->Setting2 || $this->Setting3);

and using that...

<% if AnyOfThreeSettingsTrue %>
Do Stuff
<% end_if %>

..might help?

Thank you for your help. I realize how basic a question this is.

I agree about the templates, they should be readable.

The problem I have with SS, now that I am developing a more complex website, is that it requires a clear grasp of php, but php is totally foreign to me.
