Hi,

I've got a promotional box on my website and I want to have the ability to select a site from the SiteTree through the backend, where the user will be forwarded to, when clicking on the box (image, text and button). It should be very similar to inserting a link, so I tried to use TreeDropdownField.

My code:

class Box extends Page {
	
	static $db = array();
	
	static $has_one = array(
		'Photo' => 'Image',
		'TargetContent' => 'SiteTree'
	);
	
	function getCMSFields() {
		
		$fields = parent::getCMSFields();
		
		$fields->addFieldToTab("Root.Content.Main", new TreeDropdownField("TargetContentID", "Choose a site to be forwarded to:", "SiteTree"));
		
		$fields->addFieldToTab("Root.Content.Photo", new ImageField('Photo'));
		
		return $fields;
		
	}
	
}

class Box_Controller extends Page_Controller {}

Now I already get the correct page ID, but no idea how to handle this :-?

How do I get the URL of the page ID now and how can I filter the SiteTree that will be displayed in the dropdown?

Thanks for any help in advance!

Cheers, Mario

Well to get the various properties of the TargetContent you use the built in ORM. Since you have a has_one relationship between your box and your TargetContent you can get the full TargetContent object using $TargetContent in the template or $this->TargetContent() in the PHP code.

Since you have the object you can then call all the usual SiteTree methods on them. Eg to get the URL in the template

<% if TargetContent %>$TargetContent.Link<% end_if %>

I'm sure I did try that, but now it works perfect... maybe I was drunk ;-)

Thanks for the help!

What about filtering the DropDown in the backend?
