Hi all,

I'm attempting to output some pagination for more than one page type. My function gets all the data as expected, but ".MoreThanOnePage" returns false. I followed the [url=http://doc.silverstripe.org/doku.php?id=private:recipes:paginationguide in the wiki and it works for one page type, but not in this instance.

Here's what I have in my page controller:

function LatestNews($pageLimit=2) {

        if(!isset($_GET['start']) || !is_numeric($_GET['start']) || (int)$_GET['start'] < 1) $_GET['start'] = 0;

        $SQL_start = (int)$_GET['start'];

        $articles = DataObject::get("Page", "`ClassName` IN ('DocPage', 'TechDocPage')");

        $returnarticles = $articles->getRange($SQL_start, $pageLimit);

         return $returnarticles;
}

And in my template I have the controller returning the page data as it should, but there is never any output for the pagination:

<% control LatestNews %>
    <p>$DateAdded.Format(j F Y)</p>
    <p>$Content.FirstParagraph</p>
<% end_control %>
.
.
.
<% if LatestNews.MoreThanOnePage %>
    <% if LatestNews.PrevLink %>
       <a href="$LatestNews.PrevLink">&lt;&lt; Prev</a> |
    <% end_if %>

    <% control LatestNews.Pages %>
        <% if CurrentBool %>
            <strong>$PageNum</strong>
        <% else %>
            <a href="$Link" title="Go to page $PageNum">$PageNum</a>
        <% end_if %>
    <% end_control %>

    <% if LatestNews.NextLink %>
        | <a href="$LatestNews.NextLink">Next &gt;&gt;</a>
    <% end_if %>
<% end_if %>

I must be missing something in my data object call?

I am having a similar problem - did you have any luck resolving?

If you follow the pagination recipe, it is fairly straight forward, the SQL_Limit needs to go in the DataObject::get(), rather than getRange once you pull all of the pages out.

I was being a moron; hadn't updated my template page properly!! So I wasn't having a similar problem at all!
