I am running 3.1.2 and trying to add a group of checkboxes to the CMS. I've added the form to manage the checkboxes to the CMS and that seems to work but I am unable t

I found an example on the internet from 2011 based on the 2.x framework and can't seem to get it working for 3.x. Feature.php and FeatureAdmin.php seem to work but I can't get the list of checkbox values to appear on a tab in the CMS labeled FeaturePage.php - the tab won't appear.

suggestions?

My code is below from mysite/code

FeaturePage.php
<?php
class FeaturePage extends Page {

// pages can have many features
static $many_many = array(
'Features' => 'Feature'
);

function getCMSFields() {
$fields = parent::getCMSFields();
$features=Feature::get();
$map = $features->toDropdownMap('ID', 'Name', '(Select one)', true);
$fields->addFieldToTab('Root.Features', new CheckboxSetField($name = 'Features',$title = 'Select Features',$source = $map));
}
}

class FeaturePage_Controller extends Page_Controller {
}

FeatureAdmin.php
<?php
class FeatureAdmin extends ModelAdmin {

private static $managed_models = array(
'Feature'
);

private static $url_segment = 'features';
private static $menu_title = 'Features';
}

Feature.php
<?php
class Feature extends DataObject {

private static $db = array(
'Name' => 'Varchar(255)',
'Description' => 'HTMLText'
);

public function getCMSFields() {

$fields = new FieldList();

$fields->push(new TextField('Name', 'Name of the feature'));
$fields->push(new TextareaField('Description', 'Short description'));

return $fields;
}
}

Hi,
Sorry for the late reply, I hope you did already find an answer to your question, but just in case: two things actuallywrong with your code:

- Your pages getCMSFields didn't return any fields
- toDropdownMap() doesn't exist in v3.1, use map().

FeaturePage:

<?php
class FeaturePage extends Page {

	// pages can have many features
	private static $many_many = array(
		'Features' => 'Feature'
	);

	public function getCMSFields() {
		$fields = parent::getCMSFields();
	
		$features=Feature::get();
		$map = $features->map('ID', 'Name', '(Select one)', true);
		
		$fields->addFieldToTab(
		       'Root.Features', 
		       new CheckboxSetField($name = 'Features',$title = 'Select Features',$source = $map));
	
		return $fields;
	}
}

class FeaturePage_Controller extends Page_Controller {
}

Also in Feature I would add the reverse relation, to make it possible to get the pages belonging to a certain feature:

	private static $belongs_many_many = array(
	    'FeaturePages' => 'FeaturePage'
	);

Hi Martine -

No worries. Your info helped solved the problem but it is not functioning as intended. I fixed the intended functionality by using a Data Extension. It is now working correctly. Thank you.
