using the code from the searchblok....

In pagelist blok define:

public $reservedParams=array('page=','query=','search_paths[]=','submit=','search_paths%5B%5D=' );

In getPages() in the pagelist blok add:

$pagination = Loader::helper('pagination');
                        //pagination
                        $pageSize=5;
                        $page=intval($_REQUEST['page']);
                        global $c;
                        $cID=$c->getCollectionId();
                        $cPath=$c->getCollectionPath();
                        //clean and build query string from current URI
                        $url=$_SERVER['REQUEST_URI'];
                        if( !strstr($url,'?')) $url.='?';
                        else{
                                //strip non reserved params from query string, leave the unique params
                                $qStr=substr($url,strpos($url,'?')+1);
                                $qStrParts=explode('&',$qStr);
                                $nonReservedQStrParts=array();

Cheers for your post.

Just need to work out how to only paginate a specific area on the page and not every page list.

pjhaggerty replied on Mar 19, 2009 at 10:37 am Permalink Reply

You could make a theme for the page list block that includes your pagination commands and apply it to those page lists you want pagination-ized.

(wordsmithing is fun)

Dutchwave replied on Mar 20, 2009 at 8:20 am Permalink Reply

I'm not sure where to add the code...
Does it need to be added in the controller.php?

poorleno replied on Mar 20, 2009 at 8:37 am Permalink Reply

Basically what I did was create a new template in /blocks/page_list/templates with the following code;

<?php 
   defined('C5_EXECUTE') or die(_("Access Denied."));
   $textHelper = Loader::helper("text"); 
   // now that we're in the specialized content file for this block type, 
   // we'll include this block type's class, and pass the block to it, and get
   // the content
   $reservedParams = array('page=','query=','search_paths[]=','submit=','search_paths%5B%5D=','all' );
   $pages = $cArray;
   $pagination = Loader::helper('pagination'); 
   //pagination 
   $pageSize=4; 
   $page=intval($_REQUEST['page']);
   #print $page;
   global $c; 
   $cID=$c->getCollectionId();

      } 
      $php_self=( !strstr($_SERVER['PHP_SELF'],'?') )?$_SERVER['PHP_SELF'].'?':$_SERVER['PHP_SELF'];

      <div><?php echo $pagination->getPrevious("Previous")?></div>
      <div><?php echo $pagination->getNext("Next")?></div>
 
<?php
      }
 
      for ($i = 0; $i < count($cArray); $i++ ) {
         $cobj = $cArray[$i]; 
         $title = $cobj->getCollectionName();
         $desc = $cobj->getCollectionDescription();
         $pdate = $cobj->getCollectionDatePublic();
         $a_class = '';
 
         if($controller->truncateSummaries){
            $desc = $textHelper->shortText($desc,$controller->truncateChars);
         }
?>
 
<div>    
<h1>
<?php print date("d.m.y", strtotime($pdate));?>
<?php echo $title?>
<a href="<?php echo $nh->getLinkToCollection($cobj)?>">Click to see more &gt;&gt;</a>
</h1>
<div><?php echo $desc?></div>
</div>
 
<?php
   }
}
?>

Then I assigned the template to the page list.

Hope that makes sense. Give me a shout (ben[at]oi[hypen]you[dot]com) if not and Ill try to explain it better.

Cheers.

Here's my code including thumbnail image in the list. Also some inline css, for pagination layout.

You never now someone might need it.

<?php 
    defined('C5_EXECUTE') or die(_("Access Denied."));
    $textHelper = Loader::helper("text"); 
    // now that we're in the specialized content file for this block type, 
    // we'll include this block type's class, and pass the block to it, and get
    // the content
    $reservedParams = array('page=','query=','search_paths[]=','submit=','search_paths%5B%5D=','all' );
    $pages = $cArray;
    $pagination = Loader::helper('pagination'); 
    //pagination 
    $pageSize=6; 
    $page=intval($_REQUEST['page']);
    #print $page;
    global $c; 
    $cID=$c->getCollectionId();

This controller works great with the exception of the thumbnail becomming an emtpy string. I've used an image field property.

I would assume that the imagefield attribute returns an url to the image. Any suggestions how to debug this? (keep in mind that I'm not a programmer, rather a html/css designer)

Thanks in advance

Thanks a lot, that was really helpful! :)

Just to let you know that I've try the template with 600 pages and it's extremely slow, took like 50 second before returning all the data on every request.

osu replied on Jan 31, 2011 at 12:45 pm Permalink Reply

@Olacom - did you find a faster solution to this? I need to create a way for visitors to look through around 10 sections with 1000+ pages each section...was thinking this might be a solution, but starting to think not!

Any pointers massively appreciated

olacom replied on Jan 31, 2011 at 1:06 pm Permalink Reply

Humm since they added the new block cache system into the last version, I think it does help alot since it cache the data after the first run for x amount of time.

APC help alot too.
