Update: Go to page 2 and look at the first post for the final code to do this.

I have created a ProfilePage.php page that has many Photo Sets.

I also created a PhotoSet.php object that has a Title and many Photos but only managed to have the Title Field in the Pop up.

I also created a Photo.php object that has a Caption and a Photo.

What I'm having trouble is have the ability to add multiple Photos on the Photo Set pop-up of Profile Page.

Is this even possible?

Here is the code for all 3 pages.

Again I want so that when I click on "Add Photo Set" on a Profile Page to also give me the ability to add multiple images to that Photo Set not just the Photo Set title.

ProfilePage.php

<?php

class ProfilePage extends Page {
   
   static $has_many = array(
      'PhotoSets' => 'PhotoSet'
   );
   
   function getCMSFields() {
      $fields = parent::getCMSFields();
      
      $photosetfield = new DataObjectManager(
         $this,
         'PhotoSets',
         'PhotoSet',
         array(
            'PhotoSetTitle' => 'PhotoSetTitle'
         ),
         'getCMSFields_forPopup'
      );
      $photosetfield->setAddTitle('Photo Set');
      $fields->addFieldToTab('Root.Content.PhotoSets', $photosetfield);
      
      return $fields;
   }
}

class ProfilePage_Controller extends Page_Controller {}

?>

PhotoSet.php

<?php

class PhotoSet extends DataObject {
   
   static $db = array(
      'PhotoSetTitle' => 'Varchar(255)'
   );
   
   static $has_one = array(
      'ProfilePage' => 'ProfilePage'
   );
   
   static $has_many = array(
      'Photos' => 'Photo'
   );
}

?>

Photo.php

<?php

class Photo extends DataObject {
   static $db = array(
      'PhotoCaption' => 'Varchar(255)'
   );
   
   static $has_one = array(
      'Attachment' => 'File'
   );
   
   public function getCMSFields_forPopup()   {
      return new FieldSet(
         new TextField('PhotoCaption'),
         new FileIFrameField('Attachment')
      );
   }

}

?>

Yup. Nested DataObjectManager has been out for several months now. It works just as you'd expect.. just put it in your getCMSFields function for the DataObject.

Thanks for the reply UncleCheese.

I'm guessing this has to be done to the PhotoSet.php and this is what I'm having trouble with. I don't know how to do this :\

Can you help extend my version of the PhotoSet.php ?

I tried and this is what I got which is obviously wrong and I have no idea how to fix.

<?php

class PhotoSet extends DataObject {
   
   static $db = array(
      'PhotoSetTitle' => 'Varchar(255)'
   );
   
   static $has_one = array(
      'ProfilePage' => 'ProfilePage'
   );
   
   static $has_many = array(
      'Photos' => 'Photo'
   );
   
   public function getCMSFields_forPopup()   {
      return new FieldSet(
         return new DataObjectManager(
            $this,
            'Photos',
            'Photo',
            array(
               'PhotoCaption' => 'PhotoCaption'
            )
         );
      );
   }

}

?>

Holy moly I think I got it!

Thanks Uncle Cheese.

Here is my updated code for PhotoSet.php

<?php

class PhotoSet extends DataObject {
   
   static $db = array(
      'PhotoSetTitle' => 'Varchar(255)'
   );
   
   static $has_one = array(
      'ProfilePage' => 'ProfilePage'
   );
   
   static $has_many = array(
      'Photos' => 'Photo'
   );
   
   function getCMSFields() {
      $fields = parent::getCMSFields();
      
      $photofield = new FileDataObjectManager(
         $this,
         'Photos',
         'Photo',
         'Attachment',
         array(
            'PhotoCaption' => 'PhotoCaption'
         ),
         'getCMSFields_forPopup'
      );
      $photofield->setAddTitle('Photos');
      $fields->addFieldToTab('Root.Photos', $photofield);
      
      return $fields;
   }

}

?>

Alright I thought i had it :P

I was able to get the FileDataObjectManager to appear on the pop-up but when I go to add a photo I get this warning.

[Warning] Bad class value NULL passed to ClassInfo::ancestry()

A couple tips -- in a DataObject subclass, you don't need to run parent::getCMSFields(). That's just for SiteTree objects. Just return a FieldSet. Also, you don't need to pass the 'getCMSFields_forPopup' to your constructor. Just name the function getCMSFields() and you should be fine without it.
