SimplePie: how do I use the get_item_tags element from an RSS feed in a smarty template

[guzzlemett]

From an RSS feed, using SimplePie I'm trying to access the value of the additional element 'source' using 'get_item_tags', and then use this alongside the usual title, description and so on for each item to be displayed in a news page using a smarty template.

 

Problem is that I can't access and convert 'news_source' into an item, instead of using the echo method as stated in the simplepie documentation. When adding as $tmp['news_source'] nothing is being returned. Code snippet follows:

 

$RSS = array();
	foreach($items as $item){
	$feed = $item->get_feed();
	$tmp=array();

	$news_source = $item->get_item_tags('','source');
	/*
	echo $news_source[0]["data"];
	*/

	if ($feed){
            $tmp['date'] = $item->get_date('j M Y, g:i a');
	    $tmp['content'] = $item->get_content();
	    $tmp['title'] = $item->get_title();
	    $tmp['link'] = $item->get_link();
	    $tmp['description'] = $item->get_description();
	    $tmp['news_source'] = $item->$get_news_source();

	array_push($RSS, $tmp);
	}
}

$smarty->assign( $params['assign'], $RSS );

Then in the smarty template, the output:

<div class="cont">
   <a href="{$entry.link}" target="_new">{$entry.title}</a><br>
   <span class="date">Published on: <strong>{$entry.date}</strong></span>
   <span class="source">Via : <strong>{$entry.news_source}</strong></span><br />
</div>

Thanks for any help or advice.

Have been given the solution, the code is now simplified to the following:

$RSS = array();
	foreach($items as $item){
	$feed = $item->get_feed();
	$tmp=array();

	if ($feed){
            $tmp['date'] = $item->get_date('j M Y, g:i a');
	    $tmp['content'] = $item->get_content();
	    $tmp['title'] = $item->get_title();
	    $tmp['link'] = $item->get_link();
	    $tmp['description'] = $item->get_description();
            $tmp['source'] = $item->get_item_tags('','source')[0]["data"];

	array_push($RSS, $tmp);
	}
}

$smarty->assign( $params['assign'], $RSS );

And in the smarty template:

<div class="cont">
   <a href="{$entry.link}" target="_new">{$entry.title}</a>
   <br />
   <span class="date">Published on: <strong>{$entry.date}</strong></span><br />
   <span class="source">Via : <strong>{$entry.source}</strong></span><br />
</div>
