Hi, I'm pretty new to this and having some trouble implementing a function on the homepage which lists pages from another section. I've got the news list sorted from the tutorials but can't seem to replicate it ... and trying to find documentation is a nightmare!

I've got a DocumentHolder type and a DocumentPage type:

*** in DocumentHolder.php ***

class DocumentHolder extends Page {   
   static $db = array();   
   static $has_one = array();
static $allowed_children = array('DocumentPage');
}

class DocumentHolder_Controller extends Page_Controller {}

*** in DocumentPage.php ***

class DocumentPage extends Page {
static $db = array(
'PDFdocDesc' => 'Text',
'ShowOnHomePage' => 'Text'
);
static $has_one = array(
'PDFdoc' => 'File'
);
   
function getCMSFields() {
   $fields = parent::getCMSFields();
   $fields->addFieldToTab("Root.Content.Main", new TextField('PDFdocDesc',"Document Description"));
   $fields->addFieldToTab("Root.Content.Main", new FileIFrameField('PDFdoc',"PDF Document"));    
      $fields->addFieldToTab("Root.Content.Main", new CheckboxField('ShowOnHomePage',"Show this on homepage?"));    
      $fields->removeFieldFromTab("Root.Content.Main", "Content");
            
return $fields;
}
}

class DocumentPage_Controller extends Page_Controller {
   
}

and, I'm pretty sure this is where I'm getting trouble because I just copied the news one & I don't fully understand it yet :)

class HomePage extends SiteTree {
   static $db = array(
   'SubTitle' => 'Text'
   );
   static $has_one = array(
);

class HomePage_Controller extends ContentController {
   function init() {
      parent::init();
      
      }
      
   function LatestNews($num=5) {
   $news = DataObject::get_one("NewsIntroPage");
   return ($news) ? DataObject::get("NewsArticlePage", "ParentID = $news->ID", "Date DESC", "", $num) : false;
}

   function HomeDocs($num=5) {
    $doccys = DataObject::get_one("DocumentHolder");
    return ($doccys) ? DataObject::get("DocumentPage", "ParentID = $doccys->ID", "Date DESC", "", $num) : false;
}
}

In my sidebar I'm trying to do this:

<% control HomeDocs %>
       <% if $ShowOnHomePage %>   
<li ><a href="$PDFdoc.filename" target="_blank" title="Download this file">$Title t</a></li>
      <% end_if %>
   <% end_control %>

any help with this would be much appreciated. Thanks

What error/problem are you experiencing exactly?

class HomePage_Controller extends ContentController {


Can you post the code you have for the HomePage class? I haven't been through this tutorial but I think that line should be:

class HomePage_Controller extends PageController {

Hi Aaron...I've added my Homepage class in the code above. Homepage sits at the same level as page (doesn't inherit from it) so extends sitetree rather than page.

So what is happening when you run that code exactly? It helps to know the error and where the error is occurring.

sorry....so if I try and include the HomeDocs function on my homepage all I get when I try to go to the site is a blank page with:

Error
The website server has not been able to respond to your request.

try

with an underscore between page and controller...

Put your site into dev mode so you can actually see the proper error rather then that blank generic one. So open up mysite/_config.php and add

Director::set_environment_type("dev");

or if you are doing this on a local dev environment eg WAMP or MAMP then make sure your server is in the array of dev servers in that _config

Director::set_dev_servers(array(
   'localhost',
   '127.0.0.1',
));

Once the sites in dev mode we shall see a bright red (sometimes helpful) error!.
