Hi,

does anybody know, how to get the saved value from a TrreDropdownField. How can you use "objectForKey"?
Can anybody give an example?

new TreeDropdownField('BannerLinkInternID', 'Bitte eine interne Verlinkung wählen', 'SiteTree', 'ID', 'Title', true);

Greetings, Carsten.

Hi Willr,

thats all clear and works fine. But if i choose "home" from the list (for e.g.) and save the date to the db, then the page (backend) is reloaded and the value of the list is: "(Choose or type search)".

What do i have to do to show "Home" as the selected value after saving the data to DB?

Thanks for your reply, Carsten.

I'm having the same problem, the field isn't saving back to the database. I can't get the link from my template and the field shows Choose a page rather than the page I selected.

The code I'm using is:

class Module extends Page {
static $db = array(
);
static $has_one = array(
'Photo' => 'Image',
'Header' => 'Image',
'LinkedPage' => 'SiteTree'
);
static $defaults = array(
"ShowInMenus" => 0,
);
static $can_be_root = false;
static $default_parent = 'HomePage';

function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab("Root.Content.Main", new ImageField('Header'));
$fields->addFieldToTab("Root.Content.Main", new ImageField('Photo'));
$fields->addFieldToTab('Root.Content.Main', new TreeDropdownField('LinkedPage', 'Page to link to', 'SiteTree'));
$fields->removeFieldFromTab('Root.Content.Main', 'MenuTitle');
$fields->removeByName('Metadata');
return $fields;
}

}

and in the template

$LinkedPage.Link

Am I doing something wrong or is this a bug?

Cheers,
