Hi All,

I'm really enjoying the flexibility and work flow of SilverStripe, awesome! I know I will have to code this somehow, but I was wondering if someone has implemented a way to show "x" number of comments with forward and back buttons, and maybe if they could share how they did it? Actually, I would like to be able to do something like this for a lot of things, such as news articles perhaps, so things don't scroll for miles on the page. I would appreciate any pointers.

Thanks!

I believe comments is setup to show 10 comments before beginning pagination, so you could edit the core file PageComment.php, the static variable $comments_per_page.

For creating pagination for other dataobjects you can do the following.

ReviewArticle.php

<?php

/*
* Custom Class for Review home page
*
*/

class ReviewHolder extends Page{
   
   public static $db = array();
   
   public static $has_one = array();
   
   public static $has_many = array(
   
         'Reviews' => 'Review'
   );
   
   public static $default_child = "Review";
   
   
   /**
   * Returns dataobject set containing reviews
   * @RETURN DataObjectSet
   **/
   function getAllReviews() {
         if(!isset($_GET['start']) || !is_numeric($_GET['start']) || (int)$_GET['start'] < 1){
         
         $SQL_start = 0;
         $get = "Review";
         $where = NULL;
         $sort = NULL;
         $join = NULL;
         $limit = "{$SQL_start}, 2";
         $reviews = DataObject::get($get, $where, $sort, $join, $limit);
         return $reviews;
         
      }else{
         $SQL_start = (int)$_GET['start'];;
         $get = "Review";
         $where = NULL;
         $sort = NULL;
         $join = NULL;
         $limit = "{$SQL_start}, 2";
         $reviews = DataObject::get($get, $where, $sort, $join, $limit);
         return $reviews;
      }
   }
   
   
}

class ReviewHolder_Controller extends Page_Controller{
   
}

?>

in the $limit field change the the number 2 to your desired number of objects to show.

and on your template you can do this
ReviewHolder.php

<% if getAllReviews %>
   <% control getAllReviews %>
<div class="review">
   <a href="reviews/$URLSegment">$GameCover.setWidth(160)</a>
   <h1><a href="reviews/$URLSegment">$Title.XML</a></h1>
   $Content.LimitCharacters(250)...<a href="reviews/$URLSegment">Read More</a>
</div>
<% end_control %>
<% if getAllReviews.MoreThanOnePage %>
   <p id="pagination">
<% if getAllReviews.PrevLink %>
   <a class="previous" href="$getAllReviews.PrevLink">Prev</a> |
<% end_if %>
<% control getAllReviews.Pages %>
      <% if CurrentBool %>
      $PageNum
      <% else %>
      <a class="pageNum" href="$Link" title="Go to page $PageNum">$PageNum</a>
<% end_if %>
<% end_control %>
      <% if getAllReviews.NextLink %>
   |<a class="next" href="$getAllReviews.NextLink">Next</a>
<% end_if %>
</p>
<% end_if %>
<% end_if %>

Hope that helps

Oh wow thanks IOTI! That is great. This is a awesome community thanks for the help and quick reply!

p.s. you know I didn't even realize that automatic pagination was built in, that is so cool. Thanks for pointing that out to me, I didn't have that many comments on my test page. I would really like to try the pagination with other data objects so that bit of code will come in really handy.
