Drupal6 如何调整文章下方的“添加评论”等链接（node.tpl.php 中 的 $links 变量）

如果调整链接先后顺序的话，可以用链接权重调整模块：http://drupal.org/project/linkweights

如果需要调整链接内容，有两种方法。

方法一：创建自定义模块，在该模块中应用 hook_link_alter() 。示例代码：

/**
* hook_link_alter() implementation
* for more details see
* <a href="http://api.drupal.org/api/drupal/developer--hooks--core.php/function/hook_link/6<br />
" title="http://api.drupal.org/api/drupal/developer--hooks--core.php/function/hook_link/6<br />
">http://api.drupal.org/api/drupal/developer--hooks--core.php/function/hoo...</a> * <a href="http://api.drupal.org/api/drupal/developer--hooks--core.php/function/hook_link_alter/6<br />
" title="http://api.drupal.org/api/drupal/developer--hooks--core.php/function/hook_link_alter/6<br />
">http://api.drupal.org/api/drupal/developer--hooks--core.php/function/hoo...</a> */
function mymodule_link_alter(&$links, $node) {
foreach ($links as $link => $values) {
// do something with $link

}
return $links;
}

方法二：在主题的template.php中应用 YourThemeName_preprocess_node() 函数，或者修改 phptemplate_preprocess_node() 函数（如果该函数已存在的话)。示例代码：

function phptemplate_preprocess_node(&$vars) {
$links= $vars['node']->links;
// uncomment the next line to see the current links
//var_dump($links);

// add a new link
$link_all = array(
'title' => 'See all nodes',
'href' => PATH,
//'attributes' => array('class' => 'link_class', 'id' => 'link_id', 'title' => 'link title'),
);
$links['link_all'] = $link_all;

//Modify an existing link. in this case the above added one
$links['link_all']['title'] = t('This is my custom text');

$vars['links'] = theme_links($links);
}
