hi sir,

I am a new for this platform,i have installed silverstripe v2.4.7 and it is working fine.
now i want to display audio and video in my website. for that i used the code below

Resource.php (I put this page into mysite/code/)
-----------------
<?php
class Resource extends DataObject
{
   static $db = array (
      'Name' => 'Text',
      'Description' => 'Text',
      'Category' => "Enum('Industry, Finance, Education')"
   );

   static $has_one = array (
      'Attachment' => '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')
      );
   }
}

ResourcePage.php (I put this page into mysite/code/)
----------------------------
<?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
         array(
            'Name' => 'Name',
            'Description' => 'Description',
            'Category' => 'Category'
         ), // Headings
         'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
         // Filter clause
         // Sort clause
         // Join clause
      );
$f->addFieldToTab("Root.Content.Resources",$manager);
return $f;
   }
}
class ResourcePage_Controller extends Page_Controller {
}

ResourcePage.ss (I put this page into theme/blackcandy/template/layout)
-------------------------
<div id="primaryContent" class="clearfix">
<div class="innerpad">
      <h2>$Title</h2>
         <% if URLSegment = Security %>
            <% include WelcomeMessage %>
         <% else %>
            $Content
            <% control Resources %>
               <h3>$Name</h3>
               <p>$Description</p>
               <% control Attachment %>$Player(640,480)<% end_control %>
            <% end_control %>

         <% end_if %>
         $Form
   </div>
</div>
<div id="secondaryContent">
<div class="innerpad">
      <div id="secondarynav">
         <ul>
         <% if Children %>
            <li><a href="$Link" class="current">$Title Overview</a></li>
         <% else_if Level(2) %>
            <li><a href="$Parent.Link">$Title Overview</a></li>
         <% end_if %>
            <% control Menu(2) %>   
               <li><a class="$LinkingMode" href="$Link">$MenuTitle</a></li>
            <% end_control %>
            </ul>
   </div>
   <% include Callout %>
</div>
</div>    
<div id="sideContent">
   <div class="innerpad">
   </div>
</div>
