Hallo everybody

I want to add the author (or the author alias) of an item to rss feed , cause i need it for facebook instant articles.

How i can do it? Which file i must override?

Hello there,

The author tag is already present -> www.joomlaworks.net/blog?format=feed

Another approach would be to use the JSON feed instead
www.joomlaworks.net/blog/item/264-tabs-sliders-has-a-new-home?format=json

I found a solution for making k2 rss feed more compatible with facebooks instant articles.

All you need to do is to configure some elements in the file com_k2/models/item

For the author you must find this part and add the lines
$item->description .= '<address>'.$item->author->name.'</address>';
and
$item->description .= '<address>'.$item->author->name.'</address>';

i add the <address> cause thats what FB need to grab the autor.

So the authors part will look like

//Author
if (!empty($item->created_by_alias))
{
if(!isset($item->author))
{
$item->author = new stdClass;
}
$item->author->name = $item->created_by_alias;
$item->author->email = '';
$item->description .= '<address>'.$item->created_by_alias.'</address>';
}
else
{
$author = JFactory::getUser($item->created_by);
$item->author = $author;
$item->author->link = JRoute::_(K2HelperRoute::getUserRoute($item->created_by));
$item->author->profile = $this->getUserProfile($item->created_by);
$item->description .= '<address>'.$item->author->name.'</address>';
}

i also made some changes to other elemens. for example i created a <header> and an <article> element.

i grab introtext in my new <header> with an <h2> so the facebook can grab it as a subtitle.

now the part i need for instant articles look like this and it works perfect!!!

IMPORTANT! your fulltext must have <p> elements, not <div>, otherwise facebook will not grab your fulltext!

//Item image
if ($params->get('feedItemImage') && JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.md5("Image".$item->id).'_'.$params->get('feedImgSize').'.jpg'))
{
$altText = $item->image_caption ? $item->image_caption : $item->title;
$item->description .= '<article><header><div class="K2FeedImage"><img src="'.JURI::root().'media/k2/items/cache/'.md5('Image'.$item->id).'_'.$params->get('feedImgSize').'.jpg" alt="'.$altText.'" /></div>';
}


//Item Introtext
if ($params->get('feedItemIntroText'))
{
//Introtext word limit
if ($params->get('feedTextWordLimit') && $item->introtext)
{
$item->introtext = K2HelperUtilities::wordLimit($item->introtext, $params->get('feedTextWordLimit'));
}
$item->description .= '<h2>'.$item->introtext.'</h2>';
}


//Author
if (!empty($item->created_by_alias))
{
if(!isset($item->author))
{
$item->author = new stdClass;
}
$item->author->name = $item->created_by_alias;
$item->author->email = '';
$item->description .= '<address>'.$item->created_by_alias.'</address></header>';
}
else
{
$author = JFactory::getUser($item->created_by);
$item->author = $author;
$item->author->link = JRoute::_(K2HelperRoute::getUserRoute($item->created_by));
$item->author->profile = $this->getUserProfile($item->created_by);
$item->description .= '<address>'.$item->author->name.'</address></header>';
}



//Item Fulltext
if ($params->get('feedItemFullText') && $item->fulltext)
{
$item->description .= ''.$item->fulltext.'</article>';
}

Nice one, although my two cents on this would be to develop this into a separate plugin ;)
