Using DataObject::get() to list last few updated pages that are publicly visible
24 May 2009 at 8:48pm
Hi, I have a homepage class that displays the 10 most recently updated pages on the website. The problem is, that this includes pages that are not publicly visible. The code is:
function RecentlyUpdated() {
$pages = DataObject::get("Page", "", "LastEdited DESC", "", 10);
$doSet = new DataObjectSet();
foreach($pages as $key => $data) {
$title = $data->Title;
$summary = $data->obj('Content')->FirstParagraph('html');;
$record = array(
'Link' => $data->Link(),
'Title' => $title,
'Date' => date('Y-m-d', strtotime($data->LastEdited)),
'Summary' => $summary
);
$doSet->push(new ArrayData($record));
}
return $doSet;
}What should I set the DataObject::get()'s parameters to in order to obtain just the publicly visible pages. Actually, I'd like to filter out and Forum page too. I assume that I only need to change the filter string, but I have no idea what to set it to.

Hi HansR,
I use this to only include visible pages:
$pages = DataObject::get("Page", "ShowInMenus = 1", "LastEdited DESC", "", 10);
To filter Forum pages out as well, something like this should work:
$pages = DataObject::get("Page", "ShowInMenus = 1 AND ClassName !=ForumPage", "LastEdited DESC", "", 10);

Hi NickJacobs,
Thanks for that. I'm still hoping that someone knows how to get the "show to all" pages, because I might want to include a page in the menu. However, your solution should be fine for now.

Hello,
Have you looked at how SilverStripe does this? You might want to look at methods Children(), AllChildren(), stageChildren() and liveChildren() in class Hierarchy.

Hi Ben,
The methods that you pointed to aren't the best option in this case; the get() method is the right one to find the ten most recently updated public pages. Plus, all of the pages are "live." The difference between pages is that most are "viewable by all," whereas some will be "viewable by group X." So, I'm looking to filter out the pages that have restrictive security settings, and forum pages).

If you want to check permissions then it would be easier to do this in the ORM. Tricky thing is you might have to get more then 10 as you are removing objects as you go. In this one I get all the pages (just for kicks) then adding to a list, making sure I only get 10.
$pages = DataObject::get("Page", "ShowInMenus = 1 AND ClassName !=ForumPage", "LastEdited DESC");
$output = new DataObjectSet();
if($pages) {
foreach($pages as $page) {
if($page->canView()) { // check we cant view
$output->push($page);
if($output->TotalItems() > 9) break;
}
}
}
return $output; -

That almost worked. My code ended up being:
$pages = DataObject::get("Page", "ShowInMenus = 1 AND ClassName != 'Forum'", "LastEdited DESC");
if($pages) {
$output = new DataObjectSet();
foreach($pages as $page) {
if($page->canView()) { // check we cant view
$output->push($page);
if($output->TotalItems() > 9)
break;
}
}
}
return $output;The one change is ForumPage changed to 'Forum'. Thanks for your help.
