Hi there,
I was trying to write a Module for having a Menu with Shortlinks. Therefore my Idea was a class Shortlink, inheriting from DataObject and a ShortlinkPage having many shortlinks.
This is the Code:
class ShortLink extends DataObject{
static $db = array (
'LinkTitle' => 'Text'
);
static $has_one = array (
'ShortLink' => 'Page'
);
function getCMSFields_forPopup(){
$fields = new FieldSet();
$fields->push(new TextField('LinkTitle', _t("ShortLink.LINKTITLE", "Link Title:")));
$fields->push(new TreeDropdownField("ShortLink", _t("ShortLink.SHORTLINK", "Link Target:"), "Page"));
return $fields;
}

}
class ShortLinkPage extends Page {

static $has_many = array (
'ShortLinks' => 'ShortLink'
);
public function getCMSFields() {
$fields = parent::getCMSFields();
$shortLinks = new ComplexTableField(
$this,
_t("ShortLinkPage.SHORTLINKS", "Short Links:"),
'ShortLink',
null,
null
//"ShortLink.ShortLinkPageID = {$this->ID}"
);
$fields->addFieldToTab('Root.Content.Shortlinks', $shortLinks);
return $fields;
}
public function getShortLinks(){
$page = $this;
$Shortlinks = $this->ShortLinks();
print_r($Shortlinks); // this is still not ready, but isn't my problem at the moment
/*while(!$Menublock->ID && $page->ParentID != 0){
$page = $page->Parent();
if(!method_exists($page, 'LinkToMenublock') && $page->ParentID != 0){
$page = $page->Parent();
$Menublock = $page->LinkToMenublock();
}else{
$Menublock = $page->LinkToMenublock();
}
}
//return new DataObjectSet($Menublock->Children());
return $Menublock->Children();*/
}

}
class ShortLinkPage_Controller extends ExtendedPage_Controller {
}
What doesn't work is the TreeDropDownField inside the Popup for creating a new shortlink (in Version 2.3.2 and 2.3.3, didn't tested 2.3.1). Is this a general Problem, that doesn't work or have I been doing something wrong? Elsewhere is the an alternative way, to slect a page for a collection of Links?

Gday Andre,

What do you mean by "doesn't work"? I ran up against some issues with the TreeDropdownField, but have things working ok now.

If you mean that it creates a single line box underneath the initial box, that makes it next to impossible to select a page from the tree, try changing the order of your fields in the FieldSet, such that the TreeDropdownField isn't the last one on the pop-up.

If it's something else, let me know and I'll see if I can help.

Now I'm a little confused. With "It doesn't work", I mean, the TreeDropdownField doesn't show up. Now I now I changed the order, which didn't help, and, what is more confusing, I commented the Textfield, but it still shows up (did /dev/build?flush=1 already a few times).

Here is My code again plus a Screenshot:

<?php

class ShortLink extends DataObject{
	static $has_one = array (
            'ShortLink' => 'Page'
      );

      static $db = array (
		'LinkTitle' => 'Text'
	);

	function getCMSFields_forPopup(){
		$fields = new FieldSet();
		$fields->push(new TreeDropdownField("ShortLink", _t("ShortLink.SHORTLINK", "Link Target:"), "Page"));
            //$fields->push(new TextField('LinkTitle', _t("ShortLink.LINKTITLE", "Link Title:")));

		return $fields;
	}
	
}

?>

Hi, me again,

the following is also not working. Now I get no fields inside the Popup.

<?php

class ShortLink extends DataObject{
	static $has_one = array (
            'ShortLink' => 'Page'
      );

      static $db = array (
		//'LinkTitle' => 'Text'
	);

	function getCMSFields_forPopup(){
		$fields = new FieldSet(
                  new TreeDropdownField("ShortLink", _t("ShortLink.SHORTLINK", "Link Target:"), "Page")
                  //new TextField('LinkTitle', _t("ShortLink.LINKTITLE", "Link Title:"))
            );

		return $fields;
	}
	
}

?>

Do I have a stupid mistake, or is this a bug wtihin TreeDropdown or Popup?

Got it working now. Also changed Complextablefield to Dataobjectmanager.

<?php

class ShortLink extends DataObject{
      public static $has_one = array (
            'ShortLink' => 'SiteTree'
      );

      public static $db = array (
            'LinkTitle' => 'Text'
      );

      public function getCMSFields_forPopup(){
            $fields = new FieldSet(
                  new TreeDropdownField("ShortLink", _t("ShortLink.SHORTLINK", "Link Target:"), "SiteTree"),
                  new TextField('LinkTitle', _t("ShortLink.LINKTITLE", "Link Title:"))
            );

            return $fields;
      }     
}

?>

<?php

class ShortLinkPage extends ExtendedPage {
	
	static $has_many = array (
		'ShortLinks' => 'ShortLink'
	);

	public function getCMSFields() {
		$fields = parent::getCMSFields();
		$fields->addFieldToTab('Root.Content.Shortlinks', new DataObjectManager(
                  $this,
                  _t("ShortLinkPage.SHORTLINKS", "Short Links:"),
                  'ShortLink',
                  array('LinkTitle' => _t("ShortLinkPage.LINKTITLE", "Link Title")),
                  'getCMSFields_forPopup'
            ));

		return $fields;
	}
}

class ShortLinkPage_Controller extends ExtendedPage_Controller {
}

?>

I am using SS 2.4.5 and am unable to get a TreeDropdownField to open in the popup modal window. Also, it completely breaks SimpleTinyMCEField.

I'm facing the same problem. Did you fix it?

No, so I am using the SimpleTreeDropDownField object from DataObjectManager module. It's not as fancy but it works for my purposes.
