HI, I have a site where each top level page has data associated which controls pages under it (styles etc). I'm looking for a way to specify a field in Page.php but only have it show up in the CMS if it is a top level page.....any ideas out here?

Well you could have a condition in the getCMSFields - if($this->ParentID == 0) since if its a top level page, it has no parent :).

Great thanks Will.....

the other issue Im having with this is retreiving an Image from the top level. ie I have the following function in Page_Controller:

function getSubNavBg() {
	return $this->Level(1)->SectionNavImg;	
	}

where SectionNavImg is an Image

and in my template I'm trying to set a background image on a sub nav for a section using eg:

<style>
ul#SubNav {background:url($getSubNavBg.Filename) }
</style>    

but it will not bring the filename through....am I missing something blindingly obvious? :)

Try

ul#SubNav {background:url({$SubNavBg.Filename}) }

If that doesn't work make sure $SubNavBg exists. Try a <% debug SubNavBg %> and see what it says.

Hi, doesn't seem to be any JOy here...I'll list all the relevant code in case we've missed something:

Page.php

class Page extends SiteTree {
	
	public static $db = array(
	 'SectionColour' => 'Text',
	 'SectionHighlightColour' => 'Text'
	);	
	public static $has_one = array(
	'SectionNavImg' => 'Image'
	);	
	
	function getCMSFields() {
		$fields = parent::getCMSFields();		
		
		if($this->ParentID == 0){
		$fields->addFieldToTab('Root.Content.Theme', new ColorField('SectionColour', 'Section Colour'));
		$fields->addFieldToTab('Root.Content.Theme', new ColorField('SectionHighlightColour', 'Section Highlight Colour'));		
		$fields->addFieldToTab('Root.Content.Theme', new ImageField('SectionNavImg'));
		}		
		return $fields;
	}
	
}

class Page_Controller extends ContentController {
	
	public function init() {
		parent::init();
	}
	
	
	function SectionColour() {
	return $this->Level(1)->SectionColour;	
	}
	
	function HiglightColour() {
	return $this->Level(1)->SectionHighlightColour;	
	}
	
	function SubNavBg() {
	return $this->Level(1)->SectionNavImg;	
	}	
}

In my template $SectionColour returns the correct value from the top level page, but the Image ( using $SubNavBg.Filename ) will just not come through.......

$this->Level(1)->SectionNavImg

Probably because the image is a relationship you need to return the object so try either

return $this->Level(1)->SectionNavImg();

or

return $this->Level(1)->dbObject('SectionNavImg');

The first one should work though.

Great thanks Will!
return $this->Level(1)->SectionNavImg(); works

knew it would be something simple :)
