Hi, I am iterating over the children of a "FolderPage" and calling a custom Method (Teaserable) on each child (which can be of different PageType). Unfortunately the method does not seem to exist.

In my Page_Controller I added this function:

	public function Teaserable(){
		return false;
	}

In the DefaultPage_Controller this function returns true (also tried this with 0/1 and strings as return values).
The layout for FolderPage.ss looks like this:

		<% if Children %>
TESTCHILDREN
		<% control Children %>
TESTCONTROL
		<% if Teaserable %>
TESTTEASER
		<h1>$Title</h1>
		<% if Last %>
		<div class="article last">
		<% else %>
		<div class="article">
		<% end_if %>
			$FirstImage.SetCropSize(355,180)
			<h2>$Title</h2>
			$ShortText
		</div>
		<% end_if %>
		<% end_control %>
		<% end_if %>

Unfortunately TESTTEASERD never got printed, why? All other (not custom) functions are available. Any hints and pints appreciated.

how about returning true?
or returning 1 and <% if Teaserable ==1 %> ?

It doesn't matter what I'm returning in PHP, nothing is printed. $Teaserable produces also absolutely NO output.

put the site in dev and place a Debug::show in your function - it is likely it is not being called - if that is the case then you need to post more code to give an answer.

Thanks for replying.
I've put Debug::show('Pagename') in Teaserable, but nothing special showed up (or even happend).
The hierarchy is like:
FolderPage
|-> Page
|-> DefaultPage

Output generated is:
TESTCHILDREN TESTCONTROL TESTCONTROL

Page.php

class Page extends SiteTree {
	public static $has_one = array(
		'Logo' => 'Image'
	);
	public function getCMSFields(){
		$fields = parent::getCMSFields();
		return $fields;
	}
}
class Page_Controller extends ContentController {
	public function init() {
		parent::init();
		Requirements::css(DEFAULT_THEME_DIR.'/css/default.css');
	}
	/**
	 * Can this page be teaserd by a folderPage
	 * @return bool
	 */
	public function Teaserable(){
		Debug::show('PAGE');
		return 0;
	}
}

DefaultPage.php

class DefaultPage extends Page {
	public static $db = array(
	);
	public static $has_one = array(

	);
	public static $has_many = array('Imageattachments' => 'DefaultPageImageattachment');
	public function getCMSFields(){
		$fields = parent::getCMSFields();
		return $fields;
	}
}
class DefaultPage_Controller extends Page_Controller {
	public function init() {
		parent::init();
		Requirements::css(DEFAULT_THEME_DIR.'/css/add.standard.css');
	}
	/**
	 * Can this page be teasered by a FolderPage
	 * @return bool
	 */
	public function Teaserable(){
		Debug::show('DEFAULTPAGE');
		return 1;
	}
}

FolderPage.php

class FolderPage extends Page {
	public static $db = array(
		'LayoutView' => "enum('ALL_ON_ONE,ALL_AS_ACC,SUBPAGE_TSR','ALL_ON_ONE')",
		'ForwardToSubpage' => 'Boolean'
	);
	public function getCMSFields(){
		$fields = parent::getCMSFields();
		$fields->renameField('Title', _t('FolderPage.FOLDERNAME'));
		$layoutView = new DropdownField('LayoutView', _t('General.LAYOUTVIEW'), array(
				'ALL_ON_ONE' => _t('FolderPage.ALL_ON_ONE'),
				'ALL_AS_ACC' => _t('FolderPage.ALL_AS_ACC'),
				'SUBPAGE_TSR'=> _t('FolderPage.SUBPAGE_TEASER')
			),
			'ALL_ON_ONE'
		);
		$forward = new CheckboxField('ForwardToSubpage', _t('FolderPage.FORWARD_TO_SUBPAGE'));
		$fields->addFieldToTab('Root.Content.Main', $layoutView, 'Title');
		$fields->addFieldToTab('Root.Content.Main', $forward);
		return $fields;
	}
}
class FolderPage_Controller extends Page_Controller {
	public function init() {
		parent::init();
		Requirements::css(DEFAULT_THEME_DIR.'/css/add.standard.css');
		Requirements::css(DEFAULT_THEME_DIR.'/css/add.folder.css');
	}
}

hmmm looks like your hierarchy is more like...

Page
|-> FolderPage
|-> DefaultPage

and calling Teaserable within FolderPage.ss (i.e. FolderPage_Controller, that includes Page_Controller) is NOT going to have access to Teaserable because it is in DefaultPage_Controller.

Either move Teaserable to Page_Controller (available to all pages) or to FolderPage_Controller (available to FolderPage_Controller only).

Yes, according to class hierarchy you're absolutely right. But I was speaking about Page hierarchy in the admin sitetree, that was ambiguous.

Furthermore Teaserable already *is* in Page_Controller and is *not* available in the template.

DOH! missed that... hmmm... i see why you included the sitetree - as you are iterating over children - sorry
how about 1) adding $Teaserable to the top of the layout (just to check)
then 2) adding a Debug::show for each for the children to check what pages they are...
