Code of the Page:

<?php

class PersonenPage extends Page {
   static $many_many = array(
      'PersonenObjectStandaard' => 'PersonenObject',
      'PersonenObjectUitgelicht' => 'PersonenObject'
   );
   public function getCMSFields() {
      $PersonenObjectStandaard = new ManyManyDataObjectManager (
         $this,
         'PersonenObjectStandaard',
         'PersonenObject',
         array(
            'Name'      => 'Naam',
            'Function'   => 'Functie',
            'Notes'      => 'Opmerkingen'
         ),
         'getCMSFields_forPopup','',
         'Name ASC'
      );
      $PersonenObjectStandaard->setAddTitle('Personen');
      $PersonenObjectStandaard->setSingleTitle('Persoon');
      
      $PersonenObjectUitgelicht = new ManyManyDataObjectManager (
         $this,
         'PersonenObjectUitgelicht',
         'PersonenObject',
         array(
            'Name'      => 'Naam',
            'Function'   => 'Functie',
            'Notes'      => 'Opmerkingen'
         ),
         'getCMSFields_forPopup','',
         'Name ASC'
      );
      $PersonenObjectUitgelicht->setAddTitle('Personen');
      $PersonenObjectUitgelicht->setSingleTitle('Persoon');

      $fields = parent::getCMSFields();
      
      $fields->addFieldToTab("Root.Content.Personen", new TabSet( "Personen",
         new tab('Standaard',new LiteralField('LiF1','<p>Kies hier welke personen weergegeven moeten worden.</p>'), $PersonenObjectStandaard),
         new tab('Uitgelicht',new LiteralField('LiF2',"<p>Kies hier enkele personen die met extra nadruk weergegeven moeten worden (deselecteer deze op het tabblad 'Standaard').</p>"),$PersonenObjectUitgelicht)
      ));
      return $fields;
      }
}

class PersonenPage_Controller extends Page_Controller {
      function view($id = null) {
      if($id == null)
         $id = $this->urlParams['ID'];
      if($id && is_numeric($id))
         return DataObject::get_by_id("PersonenObject", $id);
   }
}
?>

Code of the DataObject:

<?php

class PersonenObject extends DataObject{

static $db = array(
   'Name'      => 'Varchar(50)',
   'Function'   => 'Varchar(50)',
   'Address'   => 'HTMLText',
   'Phone'      => 'Varchar(50)',
   'Email'      => 'Varchar(50)',
   'URL'      => 'Text',
   'Bio'      => 'HTMLText',
   'Notes'      => 'Text',
);

static $has_one = array(
   'Image'               => 'Image',
);
static $belongs_many_many = array(
   'PersonenPage'         => 'PersonenPage'
);

function Thumbnail(){
   $Image = $this->Image();
   if ( $Image ) {
      return $Image->CMSThumbnail();
   } else {
      return null;
   }
}

function getCMSFields_forPopup() {
   return new FieldSet(
      new TextField('Name','Naam'),
      new TextField('Function','Functie'),
      new TextField('Address','Adres'),
      new TextField('Phone','Telefoon'),
      new TextField('Email','E-mail (toont een link naar een contactformulier)'),
      new TextField('URL','Website'),
      new SimpleHTMLEditorField('Bio','Biografie',array(
            'css'            => 'mysite/css/jquery.wysiwyg.css',
            'insertOrderedList'   => false,
            'insertImage'      => false,
            'justifyLeft'      => false,
            'justifyRight'      => false,
            'justifyCenter'      => false,
            'cut'            => true,
            'copy'            => true,
            'paste'            => true,
            'html'            => true)
      ),
      new myImageField('Image','Portret'),
      new TextareaField('Notes','Opmerkingen (worden niet weergegeven op de website)')
   );
}

function Link() {
   return $this->PersonenPage()->First()->URLSegment . "view/" . $this->ID;
}

}
?>

I got this working...

So I have a holder:
http://pastebin.com/f5106bdce

I create a page in the CMS for that holder.

Now I can:
http://mysite.com/holder/<any text>/12
http://mysite.com/holder/<any text>/100

eg:
http://mysite.com/holder/view/12
http://mysite.com/holder/view/100

http://mysite.com/holder/silverstripe/12
http://mysite.com/holder/silverstripe/100

Note the use us static $song in the function song().
If you don't do that then you will hit the DB for every $song.property in your template.

I did not modify the Song object at all, eg: Overriding Link()

Hi!

I took a look at this and i have a solution which takes the current controller into the url using the SSViewer object.

I dont know if it is the ideal way but it is a solution i think. Maybe some of the Silverstripe devs can take a look at this?

My code:

PersonenPage.php

<?php

class PersonenPage extends Page {
static $many_many = array(
'PersonenObjectStandaard' => 'PersonenObject',
'PersonenObjectUitgelicht' => 'PersonenObject'
);
public function getCMSFields() {
$PersonenObjectStandaard = new ManyManyDataObjectManager (
$this,
'PersonenObjectStandaard',
'PersonenObject',
array(
'Name' => 'Naam',
'Function' => 'Functie',
'Notes' => 'Opmerkingen'
),
'getCMSFields_forPopup','',
'Name ASC'
);
$PersonenObjectStandaard->setAddTitle('Personen');
$PersonenObjectStandaard->setSingleTitle('Persoon');

$PersonenObjectUitgelicht = new ManyManyDataObjectManager (
$this,
'PersonenObjectUitgelicht',
'PersonenObject',
array(
'Name' => 'Naam',
'Function' => 'Functie',
'Notes' => 'Opmerkingen'
),
'getCMSFields_forPopup','',
'Name ASC'
);
$PersonenObjectUitgelicht->setAddTitle('Personen');
$PersonenObjectUitgelicht->setSingleTitle('Persoon');

$fields = parent::getCMSFields();

$fields->addFieldToTab("Root.Content.Personen", new TabSet( "Personen",
new tab('Standaard',new LiteralField('LiF1','<p>Kies hier welke personen weergegeven moeten worden.</p>'), $PersonenObjectStandaard),
new tab('Uitgelicht',new LiteralField('LiF2',"<p>Kies hier enkele personen die met extra nadruk weergegeven moeten worden (deselecteer deze op het tabblad 'Standaard').</p>"),$PersonenObjectUitgelicht)
));
return $fields;
}
}

class PersonenPage_Controller extends Page_Controller {

   public function PersonenList() {
      $records = DataObject::get('PersonenObject');   
      return $records;
   }   

   function view($id = null) {
      
   $params = Director::urlParams();
   $id = (int)$params['ID'];

   $object = DataObject::get_by_id('PersonenObject',$id);

   if($object) {
      return $this
         ->customise(array('DisplayPersoon' => $object))
         ->renderWith(array('DisplayPersoon', 'Page'));
   } else {
      Director::redirect(Director::absoluteBaseURL() . 'not-found');
   }
}    
   
}
?>

PersonenObject

<?php

class PersonenObject extends DataObject{

   static $db = array(
      'Name' => 'Varchar(50)',
      'Function' => 'Varchar(50)',
      'Address' => 'HTMLText',
      'Phone' => 'Varchar(50)',
      'Email' => 'Varchar(50)',
      'URL' => 'Text',
      'Bio' => 'HTMLText',
      'Notes' => 'Text',
   );

   static $has_one = array(
      'Image' => 'Image',
   );

   static $belongs_many_many = array(
      'PersonenPage' => 'PersonenPage'
   );

   function Thumbnail(){
      $Image = $this->Image();
      if ( $Image ) {
      return $Image->CMSThumbnail();
      } else {
      return null;
      }
   }

   function getCMSFields_forPopup() {
      return new FieldSet(
      new TextField('Name','Naam'),
      new TextField('Function','Functie'),
      new TextField('Address','Adres'),
      new TextField('Phone','Telefoon'),
      new TextField('Email','E-mail (toont een link naar een contactformulier)'),
      new TextField('URL','Website'),
      new SimpleHTMLEditorField('Bio','Biografie',array(
      'css' => 'mysite/css/jquery.wysiwyg.css',
      'insertOrderedList' => false,
      'insertImage' => false,
      'justifyLeft' => false,
      'justifyRight' => false,
      'justifyCenter' => false,
      'cut' => true,
      'copy' => true,
      'paste' => true,
      'html' => true)
      ),
      new ImageField('Image','Portret'),
      new TextareaField('Notes','Opmerkingen (worden niet weergegeven op de website)')
      );
   }

   function Link() {
      return Director::absoluteBaseURL() . SSViewer::topLevel()->URLSegment . "/view/" . $this->ID;
   }

}
?>
