Change recent comments block to show each article only once

Hi there,

My recent comments block often features several comments about the same article, I'd like it to show only the most recent comment for any given article.

Is it possible to change the recent comments block so that it does not repeat comments about the same article?

So just like the 'most recent forum posts' block in newbb will only show the most recent post for any given topic, can this be done on the recent comments block?

Thanks a lot!

This would likely be a good enhancement to the recent comments block. There are likely a few methods you could use to do this.

For instance, you could change the php for the block so that it keeps track of whether or not a specific module item has already displayed a comment for it or not before it gets added to the displayed comments. You'd need to initialize an array for this purpose, then in the foreach loop check to see if a comment already exists for this item or not and if so skip it, and if not then add it to the comments and then add the info (probably moduleID and then itemID) to the array for the next time to check. This would be done in the /modules/system/blocks/system_blocks.php in the function b_system_comments_show.

For example, this code MIGHT work (I haven't tested it, but it should be close). Replace:
foreach (array_keys($comments) as $i) {
  $mid = $comments[$i]->getVar('com_modid');
  $com['module'] = '<a href="'.XOOPS_URL.'/modules/'.$modules[$mid]->getVar('dirname').'/">'.$modules[$mid]->getVar('name').'</a>';
  if (!isset($comment_config[$mid])) {
    $comment_config[$mid] = $modules[$mid]->getInfo('comments');
  }
  $com['id'] = $i;
  $com['title'] = '<a href="'.XOOPS_URL.'/modules/'.$modules[$mid]->getVar('dirname').'/'.$comment_config[$mid]['pageName'].'?'.$comment_config[$mid]['itemName'].'='.$comments[$i]->getVar('com_itemid').'&com_id='.$i.'&com_rootid='.$comments[$i]->getVar('com_rootid').'&'.htmlspecialchars($comments[$i]->getVar('com_exparams')).'#comment'.$i.'">'.$comments[$i]->getVar('com_title').'</a>';
  $com['icon'] = htmlspecialchars( $comments[$i]->getVar('com_icon'), ENT_QUOTES );
  $com['icon'] = ($com['icon'] != '') ? $com['icon'] : 'icon1.gif';
  $com['time'] = formatTimestamp($comments[$i]->getVar('com_created'),'m');
  if ($comments[$i]->getVar('com_uid') > 0) {
    $poster =& $member_handler->getUser($comments[$i]->getVar('com_uid'));
    if (is_object($poster)) {
      $com['poster'] = '<a href="'.XOOPS_URL.'/userinfo.php?uid='.$comments[$i]->getVar('com_uid').'">'.$poster->getVar('uname').'</a>';
    } else {
      $com['poster'] = $GLOBALS['xoopsConfig']['anonymous'];
    }
  } else {
    $com['poster'] = $GLOBALS['xoopsConfig']['anonymous'];
  }
  $block['comments'][] =& $com;
  unset($com);
}
with:
$trackedItems = array();
foreach (array_keys($comments) as $i) {
  $mid = $comments[$i]->getVar('com_modid');
  $com['module'] = '<a href="'.XOOPS_URL.'/modules/'.$modules[$mid]->getVar('dirname').'/">'.$modules[$mid]->getVar('name').'</a>';
  if (!isset($comment_config[$mid])) {
    $comment_config[$mid] = $modules[$mid]->getInfo('comments');
  }
  $com['id'] = $i;
  $com['title'] = '<a href="'.XOOPS_URL.'/modules/'.$modules[$mid]->getVar('dirname').'/'.$comment_config[$mid]['pageName'].'?'.$comment_config[$mid]['itemName'].'='.$comments[$i]->getVar('com_itemid').'&com_id='.$i.'&com_rootid='.$comments[$i]->getVar('com_rootid').'&'.htmlspecialchars($comments[$i]->getVar('com_exparams')).'#comment'.$i.'">'.$comments[$i]->getVar('com_title').'</a>';
  $com['icon'] = htmlspecialchars( $comments[$i]->getVar('com_icon'), ENT_QUOTES );
  $com['icon'] = ($com['icon'] != '') ? $com['icon'] : 'icon1.gif';
  $com['time'] = formatTimestamp($comments[$i]->getVar('com_created'),'m');
  if ($comments[$i]->getVar('com_uid') > 0) {
    $poster =& $member_handler->getUser($comments[$i]->getVar('com_uid'));
    if (is_object($poster)) {
      $com['poster'] = '<a href="'.XOOPS_URL.'/userinfo.php?uid='.$comments[$i]->getVar('com_uid').'">'.$poster->getVar('uname').'</a>';
    } else {
      $com['poster'] = $GLOBALS['xoopsConfig']['anonymous'];
    }
  } else {
    $com['poster'] = $GLOBALS['xoopsConfig']['anonymous'];
  }
  if (count($trackedItems) > 0) {
    $itemMatch = false;
    foreach (array_keys($trackedItems) as $j) {
      if ($comments[$i]->getVar('com_modid') == $trackedItems[$j]['modid'] && $comments[$i]->getVar('com_itemid') == $trackedItems[$j]['itemid']) {
          $itemMatch = true;
      }
    }
    if ($itemMatch) {
      $block['comments'][] =& $com;
      $trackedItems[] = array('modid' => $comments[$i]->getVar('com_modid'), 'itemid' => $comments[$i]->getVar('com_itemid') );
    }
  } else {
    $block['comments'][] =& $com;
    $trackedItems[] = array('modid' => $comments[$i]->getVar('com_modid'), 'itemid' => $comments[$i]->getVar('com_itemid') );
  }
  unset($com);
}
BTW, I'm sure the code can be made more elegant, and as presented above, it may not work, but this hack should get you closer.

Thanks a lot mboyden

I tried that but the result is that only one comment is shown, its the most recent comment and as far as I can figure its the only comment that has received no replies (so, recent comments are not showing for articles that have mutiple comments)

I've tried to figure the solution but can't see it

Any ideas

Thanks a lot!!!

Try:
if (!$itemMatch) {

Hi Trabis

Thanks a lot! That did it

But there is one small problem remaining, not sure if there is a simple solution.

In the block of course you must state the number of comments you want to be shown (for me its 10) but after the above change the number of comments shown varies. The system is checking the 10 most recent comments and only displaying 6 because the other 4 are previous comments from one of those articles

Any solution (this is way beyond me)

Thanks again!

I see, try to replace the entire function with this one:

function b_system_comments_show($options)
{
    $block = array();
    include_once XOOPS_ROOT_PATH.'/include/comment_constants.php';
    $comment_handler =& xoops_gethandler('comment');
    $criteria = new CriteriaCompo(new Criteria('com_status', XOOPS_COMMENT_ACTIVE));
    $criteria->setLimit(intval($options[0] * 10));
    $criteria->setSort('com_created');
    $criteria->setOrder('DESC');
    $comments = $comment_handler->getObjects($criteria, true);
    $member_handler =& xoops_gethandler('member');
    $module_handler =& xoops_gethandler('module');
    $modules = $module_handler->getObjects(new Criteria('hascomments', 1), true);
    $comment_config = array();

    $trackedItems = array();
    $count = 0;
    foreach (array_keys($comments) as $i) {
        if ( $count == $options[0])  continue;
        $mid = $comments[$i]->getVar('com_modid');
        $com['module'] = '<a href="'.XOOPS_URL.'/modules/'.$modules[$mid]->getVar('dirname').'/">'.$modules[$mid]->getVar('name').'</a>';
        if (!isset($comment_config[$mid])) {
            $comment_config[$mid] = $modules[$mid]->getInfo('comments');
        }
        $com['id'] = $i;
        $com['title'] = '<a href="'.XOOPS_URL.'/modules/'.$modules[$mid]->getVar('dirname').'/'.$comment_config[$mid]['pageName'].'?'.$comment_config[$mid]['itemName'].'='.$comments[$i]->getVar('com_itemid').'&com_id='.$i.'&com_rootid='.$comments[$i]->getVar('com_rootid').'&'.htmlspecialchars($comments[$i]->getVar('com_exparams')).'#comment'.$i.'">'.$comments[$i]->getVar('com_title').'</a>';
        $com['icon'] = htmlspecialchars( $comments[$i]->getVar('com_icon'), ENT_QUOTES );
        $com['icon'] = ($com['icon'] != '') ? $com['icon'] : 'icon1.gif';
        $com['time'] = formatTimestamp($comments[$i]->getVar('com_created'),'m');
        if ($comments[$i]->getVar('com_uid') > 0) {
            $poster =& $member_handler->getUser($comments[$i]->getVar('com_uid'));
            if (is_object($poster)) {

            } else {
                $com['poster'] = $GLOBALS['xoopsConfig']['anonymous'];
            }
        } else {
            $com['poster'] = $GLOBALS['xoopsConfig']['anonymous'];
        }
        if (count($trackedItems) > 0) {
            $itemMatch = false;
            foreach (array_keys($trackedItems) as $j) {
                if ($comments[$i]->getVar('com_modid') == $trackedItems[$j]['modid'] && $comments[$i]->getVar('com_itemid') == $trackedItems[$j]['itemid']) {
                    $itemMatch = true;
                }
            }
            if (!$itemMatch) {
                $block['comments'][] =& $com;
                $trackedItems[] = array('modid' => $comments[$i]->getVar('com_modid'), 'itemid' => $comments[$i]->getVar('com_itemid') );
                $count++;

        unset($com);
    }
    return $block;

Thank you guys for this very useful hack. Is it posible to hide the comments to users who have no rights to a module?

Hum, try this way:
function b_system_comments_show($options)
{
    global $xoopsUser;
    include_once XOOPS_ROOT_PATH.'/include/comment_constants.php';
    $limit = 10; // If you  are not getting suficient results, please increase a little more this number
    $block = $comment_config = $trackedItems = array();

    $comment_handler =& xoops_gethandler('comment');
    $moduleperm_handler =& xoops_gethandler('groupperm');
    $member_handler =& xoops_gethandler('member');
    $module_handler =& xoops_gethandler('module');

    $criteria = new CriteriaCompo(new Criteria('com_status', XOOPS_COMMENT_ACTIVE));
    $criteria->setLimit(intval($options[0] * $limit));
    $criteria->setSort('com_created');
    $criteria->setOrder('DESC');

    $comments = $comment_handler->getObjects($criteria, true);
    $modules = $module_handler->getObjects(new Criteria('hascomments', 1), true);
    
    $count = 0;
    foreach (array_keys($comments) as $i) {
        if ( $count == $options[0])  continue;
        $mid = $comments[$i]->getVar('com_modid');

        if ($xoopsUser) {
            if (!$moduleperm_handler->checkRight('module_read', $mid, $xoopsUser->getGroups())) {
                continue;
            }
        } else {
            if (!$moduleperm_handler->checkRight('module_read', $mid, XOOPS_GROUP_ANONYMOUS)) {
                continue;
            }
        }
        
        $com['module'] = '<a href="'.XOOPS_URL.'/modules/'.$modules[$mid]->getVar('dirname').'/">'.$modules[$mid]->getVar('name').'</a>';
        if (!isset($comment_config[$mid])) {
            $comment_config[$mid] = $modules[$mid]->getInfo('comments');
        }
        $com['id'] = $i;
        $com['title'] = '<a href="'.XOOPS_URL.'/modules/'.$modules[$mid]->getVar('dirname').'/'.$comment_config[$mid]['pageName'].'?'.$comment_config[$mid]['itemName'].'='.$comments[$i]->getVar('com_itemid').'&com_id='.$i.'&com_rootid='.$comments[$i]->getVar('com_rootid').'&'.htmlspecialchars($comments[$i]->getVar('com_exparams')).'#comment'.$i.'">'.$comments[$i]->getVar('com_title').'</a>';
        $com['icon'] = htmlspecialchars( $comments[$i]->getVar('com_icon'), ENT_QUOTES );
        $com['icon'] = ($com['icon'] != '') ? $com['icon'] : 'icon1.gif';
        $com['time'] = formatTimestamp($comments[$i]->getVar('com_created'),'m');
        if ($comments[$i]->getVar('com_uid') > 0) {
            $poster =& $member_handler->getUser($comments[$i]->getVar('com_uid'));
            if (is_object($poster)) {
                $com['poster'] = '<a href="'.XOOPS_URL.'/userinfo.php?uid='.$comments[$i]->getVar('com_uid').'">'.$poster->getVar('uname').'</a>';
            } else {
                $com['poster'] = $GLOBALS['xoopsConfig']['anonymous'];
            }
        } else {
            $com['poster'] = $GLOBALS['xoopsConfig']['anonymous'];
        }
        if (count($trackedItems) > 0) {
            $itemMatch = false;
            foreach (array_keys($trackedItems) as $j) {
                if ($comments[$i]->getVar('com_modid') == $trackedItems[$j]['modid'] && $comments[$i]->getVar('com_itemid') == $trackedItems[$j]['itemid']) {
                    $itemMatch = true;
                }
            }
            if (!$itemMatch) {
                $block['comments'][] =& $com;
                $trackedItems[] = array('modid' => $comments[$i]->getVar('com_modid'), 'itemid' => $comments[$i]->getVar('com_itemid') );
                $count++;
            }
        } else {
            $block['comments'][] =& $com;
            $trackedItems[] = array('modid' => $comments[$i]->getVar('com_modid'), 'itemid' => $comments[$i]->getVar('com_itemid') );
            $count++;
        }
        unset($com);
    }
    return $block;
}


I did not tested it so please, be kind to report the results.
Thanks.

trabis,

this works very well, thank you. Just one bad thing: the anonymous can see every comment, but when you login, you see only the comments, you have rights for.

Are you sure,?
I mean, have you tried to click on the comment as anonym?
If yes, did you get a "NO PERMISSION".
I´m saying this because anonyms may have permissons set and you did not realised.
Please try this.
Thanks.
