Hi Fiord, you need to do something like this:

mysite/code/Page.php

//functions in Page_controller, gets a list of objects and paginates them
function getObjects() {
if(!isset($_GET['start']) || !is_numeric($_GET['start']) || (int)$_GET['start'] < 1) $_GET['start'] = 0;
$SQL_start = (int)$_GET['start'];
$doSet = DataObject::get(
$callerClass = "$PageClass", // enter the Object type (e.g. 'MyPageType')
$filter = "`ParentID` = '".$this->ID."'",
$sort = "Date DESC",
$join = "",
$limit = "{$SQL_start}, $itemsPerPage" // enter the number of items per page (int)
);

return $doSet ? $doSet : false;
}

mysite/templates/Layout/Page.ss

<% if getObjects.MoreThanOnePage %>
<p class="pageNumbers">
<% if getObjects.PrevLink %>
<a href="$getObjects.PrevLink"><< Prev</a> |
<% end_if %>

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

<% if getObjects.NextLink %>
| <a href="$getObjects.NextLink">Next >></a>
<% end_if %>
</p>
<% end_if %>

H!
I need to do something like this but data that I need to paginate, are the result of my query.
Can you help me to print 10 result for page please?I'm unable to realize correctly..
This is the function with my query.

function Conn()
   {   global $db_pandora;
    $record=$db_pandora->query('SELECT * FROM mm_ville LIMIT 0, 30');

    $rec=array();
   
while($rec[]=$record->nextRecord())
{ }

$doSet = new DataObjectSet();

foreach($rec as $key)
{ $record = array(
'Id' => $key['id'],
'Nome' => $key['name'],
);
doSet->push(new ArrayData($record));}

return $doSet;
   }

Hi Aram.

Thanks for your post. I have implemented your code on my site and have run into an error when I click through the second page:

"StartTag: invalid element name"

The code I am using is:

PhotoGalleryPage.php

function getObjects() {
   if(!isset($_GET['start']) || !is_numeric($_GET['start']) || (int)$_GET['start'] < 1) $_GET['start'] = 0;
   $SQL_start = (int)$_GET['start'];
   $doSet = DataObject::get("PhotoGallery", "", "PhotoDate DESC", "", "{$SQL_start}, 4" );

   return $doSet ? $doSet : false;
}   

PhotoGalleryPage.ss

<div id="photoList">   
   <% control getObjects %>
   <div class="photoFrame">
       <div class="photoImageField">$Photo.SetRatioSize(270,203)</div>
         <div class="photoCaptionField">$PhotoCaption</div>
         <div class="photDateField">Taken: $PhotoDate.format(d-M-y)</div>
         <div class="clear"></div>
      </div>   
   <% end_control %>      
   
   <% if getObjects.MoreThanOnePage %>
      <p class="pageNumbers">
      <% if getObjects.PrevLink %>
      <a href="$getObjects.PrevLink"><< Prev</a> |
      <% end_if %>
      <% control getObjects.Pages %>
      <% if CurrentBool %>
      <strong>$PageNum</strong>
      <% else %>
      <a href="$Link" title="Go to page $PageNum">$PageNum</a>
      <% end_if %>
      <% end_control %>
      <% if getObjects.NextLink %>
      | <a href="$getObjects.NextLink">Next >></a>
      <% end_if %>
      </p>
      <% end_if %>
   </div>

</div>

   

Everything seems to be ok. Any suggestions on what might be causing the issue would greatly received.

Many thanks

Marc

Does it work on SS3? the getObjects is working fine, but the Next/Prev buttons aren't showing up

Dimenicius, check out the SS3 documentation for PaginatedList.
