Hi guys,

Okay, so, I've decided, to make life easy for the site admin, to default custom properties in a new page to match that of the home page. This way, the page doesn't look nasty if they've forgotten to add anything. This works great for single items, as I can just use

<% if Property %>
  $Property
<% else %>
  <% control Page(home) %>
    $Property
  <% end_control %>
<% end_if %>

However, a problem arises if the property is an array, as I can't nest control statements, and using

<% control Page(home).Property %>

doesn't work. The question is, then; how can I use the property of some other page in a control statement in a template?

Thanks,
Lee

how about replacing...

<% control Page(home).Property %>

with...

<% control Page(home) %>
<% if Property %>
do stuff
<% end_if %>
<% end_control %>

I'd expect that to work...

Hi Swaiba,

Yes, that would work if the property was a string or somesuch, but it's an array of items (DataObjects), thus I'd need to use "control" to iterate through it. As controls can't be nested, it means I can't access the data.

Thanks for commenting, though :)

As controls can't be nested??

I don't follow that, I think I missed the "an array" part. A simple solution is to place your array into a DataObjectSet...

<% control Page(home) %> 
	<% if PropertyAsDataObjectSet %> 
		<% control PropertyAsDataObjectSet %> 
			do stuff 
		<% end_control %>
	<% end_if %> 
<% end_control %>

function PropertyAsDataObjectSet() {
	$dos = null;
	if (count($this->Property)) {
		$dos = new DataObjectSet();
		foreach ($this->Property as $do) {
			$dos->push($do);
		}
	}
	return $dos;
}

Hi Swaiba,

Thanks, but I can't do that either, because I'd still be nesting control expressions, which isn't allowed. Otherwise, I could use it as it :)

How is that? Where did you get that idea?
I nest controls all the time...

Doh! And therein lies my problem :) I'm not sure where I read that, but I've been avoiding it like soap on the floor of a communal shower.

Thanks buddy, I'll give that a go :)

Good luck Lee, all silverstripe Bristolians together!
