Hello,

this is primary a question for UncleCheese, but any1 who know the answer would be welcome to give it.

I have seen the code examples for DOM/Uploadify posted in this thread:
http://www.silverstripe.org/dataobjectmanager-module-forum/show/7009?start=0
and it works (I've tried it with a bit of different names for sth, but mainly the same thing). now I would like to be able to attach 2 files to same Dataobject. I've tried doing sth like:

<?php
class Resource extends DataObject
{
   static $db = array (
      'Name' => 'Text',
      'Description' => 'Text',
      'Category' => "Enum('Industry, Finance, Education')"
   );
   
   static $has_one = array (
      'Attachment' => 'File',
'MYFILE' => 'File,
      'ResourcePage' => 'ResourcePage'
   );
   
   public function getCMSFields_forPopup()
   {
      return new FieldSet(
         new TextField('Name'),
         new TextareaField('Description'),
         new DropdownField('Category','Category', singleton('Resource')->dbObject('Category')->enumValues()),
         new FileIFrameField('Attachment'),
new FileIFrameField('MYFILE'),
      );
   }
}
?>

and it doesn't work. I added sth like:

<?php
class ResourcePage extends Page
{
   static $has_many = array (
      'Resources' => 'Resource'
   );
   
   public function getCMSFields()
   {
      $f = parent::getCMSFields();
      $manager = new FileDataObjectManager(
         $this, // Controller
         'Resources', // Source name
         'Resource', // Source class
         'Attachment', // File name on DataObject
'MYFILE', // Second file name on DataObject
         array(
            'Name' => 'Name',
            'Description' => 'Description',
            'Category' => 'Category'
         ), // Headings
.....
and it just gives out errors. Any ideas how to do this? I need 2 separate file uploaded in 2 different categorys in same Dataobject

Hey mate, I have tried that, didn't help much - for some reason just changing FileDataObjectManager to DataObjectManager doesn't do much help, if you had sth else in mind plz do tell.

Then I wanted to use the code you supplied on your website with frontend form for Jop aplication (kinda simmilar to what I want - it has a file and multifile upload thingie and it rly is all i need in the end.
The files can be found at this location:
http://www.leftandmain.com/silverstripe-tutorials/2010/08/30/using-uploadify-in-frontend-forms/

Anyways, long story short, I have placed them in /ss/mycode and .../templates/layout folders as neaded, rebuilt a side (/dev/build) and I can go to admin interface and create a new JobAplicationPage, but then the following error pops up:

ERROR [Notice]: Undefined index: ManyS3File

Plz help

Mate I am probably boring my now, but I don't see the problem, can you fix this for me?
This is my actual code

<?php
class Challenge extends DataObject{

   static $db=array(
      'Naziv' => 'Text',
      'Datum' => 'Date',
      'Opis'=>'Text',
      'Aktivan'=>'Boolean'
   );
   
   static $has_one=array(
      'Izazov'=>'File',
      'Razultati'=>'File',
      'Izazovi' => 'Izazovi',
      'IzazoviArhiva' => 'IzazoviArhiva'
   );
   
   public function getCMSFields_forPopup(){
   
      return new FieldSet(
         new TextField('Naziv','Naziv izazova'),
         new DatePickerField('Datum'),
         new TextField('Opis','Krataki opis'),
         new FileIFrameField('Izazov'),
         new FileIFrameField('Rezultati'),
         new CheckboxField('Aktivan')
      );
   }
}
?>

<?php

   static $has_one = array(
      'Photo' => 'Image'
   );
   
   static $allowed_children = array(
      'IzazoviArhiva',
      'Challenge'
   );
   
   static $has_many=array(
      'Challenges'=>'Challenge'
   );

   
   static $db = array(

   );

   public function getCMSFields(){
$fields = parent::getCMSFields();
    $manager = new DataObjectManager(
         $this, // Controller

         'Challenge', // Source class
         'Izazov', // File name on DataObject

    $fields->addFieldToTab("Root.Content.Izazovi",$manager);
return $fields;
}
}

class Izazovi_Controller extends Page_Controller {

Hey mate, thank you, i figured it out, you helped a lot.
Btw, how to formulate a <% if $Rezultati %> in .ss file so that if there is a filed uploaded it would show it, if not then nothing?

I have tried this:

         <% control getChallenges(2) %>
                     
               <h3>$Naziv</h3>
               <p class="document_text"><b>Datum:</b> $Datum</p>                      
               <p class="document_text"><b>Kratki opis:</b> $Opis</p>
               <p>&nbsp;<a href="$Izazov.URL">Preuzmi izazov</a></p>
               <% if $Rezultati %>
                  <p>Rezultati izazova:</p>
                  <p>&nbsp;<a href="$Razultati.URL">Rezultati</a></p>
               <% end_if %>
               </br>      
         <% end_control %>

but it doesn't work... I need $Rezultati file to only be shown once it is uploaded, since the Iizazov file is some kind of a challenge, and once the certain amount of time has passes we will announce the ppl who managed to finish it and show resaults in $Rezultati (pdf file) so once that is uploaded for that particular challenge it is supposed to be shown.

EDIT:

Been trying with return file_exists($this->Rezultati); in some function but it doesn't work also, always returns bool(false) so I rly don't know how to check if there is a file uploaded or not.

EDIT2:

works, had a typo in filename
