Hi, I'm trying to output images in a sidebar which link to other pages in the site. I've got it working fine, but just cannot get the page links to output. I'm sure it's something easy I'm overlooking....hopefully someone else can spot it ....

LinkImageItem.php

class LinkImageItem extends DataObject
{
   static $db = array (      
      'Caption' => 'Text'
   );
   
   static $has_one = array (
      'LinkImage' => 'Image',
      'Page' => 'Page',
      'Link' => 'SiteTree'
   );
   
   public function getCMSFields_forPopup()
   {
      return new FieldSet(
         new TextField('Caption','Caption'),
         new SimpleTreeDropdownField("LinkID", "Select a page to link to", "SiteTree"),
         new ImageField('LinkImage','Link Image')
      );
   }
}

Page.php

class Page extends SiteTree {
   
   public static $db = array();
   
   public static $has_one = array();
   
   public static $has_many = array(   
   'ResourceFile' => 'File',
   'LinkImageItems' => 'LinkImageItem'   
   );   
   static $icon = "themes/smartpack/images/treeicons/page";   
   
   public function getCMSFields()
   {
      $f = parent::getCMSFields();
      
      $f->addFieldsToTab("Root.Content.ResourceFiles", new AssetManager($this,"ResourceFiles","ResourceFile"));
      
      // setup the page link images
      
      $manager = new ImageDataObjectManager(
         $this, // Controller
         'LinkImageItems', // Source name
         'LinkImageItem', // Source class
         'LinkImage', // File name on DataObject
         array('Name' => 'Name'),
         'getCMSFields_forPopup' );
         
$f->addFieldToTab("Root.Content.LinkItems",$manager);
      
      return $f;
      }   
   
}

In Page.ss

<% control LinkImageItems %>

$LinkImage
<a href="$Link">$Caption</a>

<% end_control %>

Tried all sorts of different ways in the template, but the link never outputs (everything else does)

any ideas??

"Link" is a really bad choice of a fieldname because it is a function on SiteTree objects. But assuming that's not an issue, you have $Link returning a SiteTree object, so the correct code would be $Link.Link

Hi, thanks, I've renamed Link to PageLink, and $PageLink.Link works as it should.

Cheers
