  Postnukers,
  
  I have been trying to figure out how to use the pager for pnRender and just can't figure it out. I did look through the documentation and the forum and really didn't see anything. Can someone point me to a resource or explain how to use the pager? Here are some specifics....
  
  I have a search function for my book module. I want to include a pager if the results get over about 20. So, when the search is done I have an array containing the data for article urls ($art_urls). I am using a pnRender object to display the results...
  
  

  Code

  $pnRender = new pnRender('Book');
  $pnRender->assign('art_urls', $art_urls);
  return $pnRender->fetch('book_user_search.htm');

  
  
  And the template is very simple...
  
  

  Code

  <!--[*  $Id: book_admin_main.htm,v 1.2 2006/11/30 19:29:32 paustian exp $  *]-->
  <!--[section name=i loop=$art_urls]-->
  <!--[$art_urls[i]]--><br />
  <!--[/section]-->

  
  
  What I would like to do is add a pager and I cannot figure out how to do it. Any help is appreciated.
  
  BTW. I will be releasing a much improved book module in the next few weeks. For a sneak peek at the kinds of things it can do, go to http://www.microbiologytext.com/

  In your PHP file add this code....
  
  

  Code

  $pnRender->assign('pager', array('numitems' => {...total number of item...},
                                   'itemsperpage' => {...number of items displayed...}));

  
  
  Then in your template add this where you want the pager to show....
  

  Code

  <!--[pager show=page rowcount=$pager.numitems limit=$pager.itemsperpage txt_first=$L_MORE posvar=startnum shift=1]-->

  cyber_wolf,
  
  Thanks a bunch, that worked. So here is a summary of what I did. $art_urls is just an array of URLs
  
  

  Code

  $pnRender = new pnRender('Book');
  $pnRender->assign('art_urls', $art_urls);
  $pnRender->assign('pager', array('numitems' => $total,
                                   'itemsperpage' => 25));
  return $pnRender->fetch('book_user_search.htm');

  
  
  Then here is the working htm code in the book_user_search.htm file
  
  

  Code

  <!--[section name=i loop=$art_urls max=$pager.itemsperpage]-->
  <!--[$art_urls[i]]--><br />
  <!--[/section]-->
  
  <!--[pager show=page rowcount=$pager.numitems limit=$pager.itemsperpage txt_first=$L_MORE posvar=startnum shift=1]-->

  
  
  Note the limit on the section. This is critical to get it to only list the lines that the pager is pointing to. One other question, what does $L_MORE stand for. I could find no reference to it.

  I don't know. I saw it in an example and hasn't caused me any problems. Probably since $L_MORE was never defined. Looks like that parameter can be removed.
