Joomla K2 -按ID获取文章链接

Question

如何通过文章的ID检索文章的链接？

我想到了这样的事情：

$link = get_link(34); // where 34 is the article ID

<a href="<?php echo $link; ?>">Article link</a>

UPDATE我的代码如下(用代码更新)：

Mysql query: "SELECT id, title, extra_fields FROM xxxxx_k2_items WHERE catid = ".$catid

$n=0; //counter
while($row = mysql_fetch_array($result)){
  $titles[$n] = $row['title'];
  $links[$n] = JRoute::_(ContentHelperRoute::getArticleRoute($row['id'], $catid));
  $n++;
}

好的，现在这检索像/joomla/index.php/currentpage?id=4这样的链接，其中4是正确的id，但是链接不工作！写错了一页。我的疑问是:您的代码也适用于K2文章吗？因为我使用的是K2文章，而不是默认的joomla文章。编辑:是的，我检查了我的疑问，您的代码链接到Joomla文章的ID，但我使用的ID是K2文章！注意:我需要链接

您应该包括K2路由

require_once(JPATH_SITE.DS.'components'.DS.'com_k2'.DS.'helpers'.DS.'route.php');

您应该同时更新mysql查询和PHP代码，因为您还需要来自k2类别表的信息，下面是一个示例

$db = JFactory::getDBO();
$query = '
    SELECT 
        a.id AS id,
        a.extra_fields AS extrafields,
        a.catid AS catid,
        a.title AS title,
        a.introtext AS introtext,
        a.alias AS alias,
        c.alias AS catalias
    FROM 
        #__k2_items AS a 
        LEFT JOIN #__k2_categories AS c ON ( a.catid = c.id ) 
        WHERE a.published = 1 AND a.catid = '.$catid;
$db->setQuery($query);
$articles = $db->loadObjectList();
$n=0;
foreach ($articles as $article) {
    $titles[$n] = $article->title;
    $links[$n] = K2HelperRoute::getItemRoute($article->id.':'.urlencode($article->alias),$article->catid.':'.urlencode($article->catalias));
    $n++;
}
