如何在Drupal 7中更改单个节点的每页评论数？

Question

i would like to change the comments per page for only a single node. Let's say that the defaul number of comments per page for the content type "article" is 50 and i want change this to 10 only for the article with nid=171.

$node = menu_get_object('node',1); if($node && $node->nid = 171) {......}

Any hint? Thanks.

If you want to control the number of comments on individual pages, I would suggest installing Views module which allow for easy creation of any lists of things, including comments. With Views, you can create a block with comments for any node and use that instead of regular comments block. Also, you can have several different blocks with different number of comments, and attach whatever block you want to whatever node. Using Context module would help too, it allows to assign blocks and other elements to pages with much more sophisticated controls than Drupal core block management.

Since it's a form you have to alter it and change comments number from code.

i found a solution even if a bit rude. To disable the node's default comments i used a preprocess function in template.php file of my subtheme and disbled the $content['comments'] variable used in the comment-wrapper.tpl.php template:

function MYSUBTHEMENAME_preprocess_comment_wrapper(&$vars){
$node = menu_get_object();
if($node):
if($node->type === 'forum' && $node->nid == 171):
unset($vars['content']['comments']);
endif;
endif;
}

Note that i did it for comment wrapper variables/template and not for the node vfariables/template in order to unset the comments but to keep the comment form.

Then i created a view block of comments with a filter for the nid of the comment's node. This works well for my purposes but if you find a more elegant way let me know. :)

I spent a time looking comment.module and found this in comment_form_node_type_form_alter

$form['comment']['comment_default_per_page'] = array(
      '#type' => 'select',
      '#title' => t('Comments per page'),
      '#default_value' => variable_get('comment_default_per_page_' . $form['#node_type']->type, 50),
      '#options' => _comment_per_page(),
    );

So I put that in my template.php

function THEMENAME_preprocess_page(&$variables){
  if (isset($variables['node']->type)) {
     if ($variables['node']->type == 'forum') {
         variable_set('comment_default_per_page_' . 'forum', 4);
     }
  }
}

It worked for me, I hope it helps.
