Counting a controll loop
10 May 2011 at 4:11am
I know this has been discussed alot throughout the Silverstripe community but I can't seem to get it working, maybe I'm just missing something simple!
I basically have the below code, but I wan't to add the class 'last' to every 6th item for CSS purposes.
(ProjectHolder.ss)
<% control Children %>
<div class="project">
<p>info</p>
</div>
<% end_control %>People seem to be talking about code similar to this....
(ProjectPage.php)
public function IsSixth(){
return ($this->iteratorPos % 6) == 0;
}But it doesn't work for me... if I do '$iteratorPos' in my .ss file, It prints the iteratorPos, but by trying a simple print_r($this->iteratorPos) in my IsSixth function it returns NULL... so I'm presuming this is the problem.

make sure you put function IsSixth() inside the page class instead of page controller class. Like this.
class ProjectPage extends Page
{
...
public function IsSixth(){
return ((($this->iteratorPos+1) % 6 ) == 0 && $this->iteratorPos!=0);
}
...
}class ProjectPage_Controller extends Page_Controller
{
//not in here
}take a note, the $this->iteratorPos start at 0, so if you are after the sixth element you need use ($this->iteratorPos+1). Also I assume you don't want to add the 'last' class to the first element, that's what $this->iteratorPos != 0 is for.
In your template do the following.
<% control Children %>
<div class="project <% if IsSixth %>last<% end_if %>">
<p>info</p>
</div>
<% end_control %> -

If you're using 2.4 you can also use MultipleOf or Modulus directly in the template - http://doc.silverstripe.org/sapphire/en/reference/advanced-templates#modulus-and-multipleof
<% if MultipleOf(6) %>sixth<% end_if %> should work.

Thanks guys... very helpful... Ben's fix for my IsSixth function works but In the end I when for the <% if MultipleOf(6) %> option, I didn't realise that SilverStripe had that function built in
Cheers!
