Hello All!

Im trying to do something like this

<% if TotalItems - Pos = 6 %>
... do this code ...
<% end_if %>

but keep getting an error. is there a way to do PHP style if statements in a template?

as in <= , >= , % , ect.

What you should do is in the Page_Controller class for that page type, create a new function that does the calculation and returns a boolean to your template. Something like:

function FunctionName() {
if($this->TotalItems - $this->Pos == 6) {
return true;
} else {
return false;
}
}

Note, I am unsure what TotalItems and Pos actually are, but I am assuming they are part of the page object if you are referencing them in the template.

So, then, in your template:

<% if FunctionName %>
... do this code ...
<% end_if %>

The idea is to remove such logic from your template and always handle it in your controller.

Oh and to answer your question, no, you can't use PHP in a template. This forces you to use the MVC model the way you should.
