[SimplePie] using txp:feed within link form

I’m trying to use the links list within textpattern to build a link list to to automatically generate content.

essentially, on the page, I’d use something like this:

<txp:linklist category="news" form="noted" limit="5" sort="linksort asc" />

the form (‘noted’) that it references would look like this:

<txp:feed><txp:link_url /></txp:feed>

Depending on the number of links in the ‘news’ category, i’d expect the output to look something like this:

<h3>Title of RSS Feed (from link #1)</h1>
<ul><li>post 1</li> through <li>post 5</li></ul>
<h3>Title of RSS Feed (from link #2)</h1>
<ul><li>post 1</li> through <li>post 5</li></ul>

instead, i get this error:

cURL error 6: Couldn’t resolve host ‘link_url%20%2F%3E’cURL error 6: Couldn’t resolve host ‘link_url%20%2F%3E’

any help would be greatly appreciated.

Tags that need to be parsed, need to be parsed (that didn’t sound right). Anyways, to the code to work you need to edit the feed() function (which ever plugin that might be) so that it parses the contained statement ($thing paramerter) with parse().

Currently the function, (<txp:feed /> tag) is feeding the <txp:link_url /> to simplepie as is.

Re: [SimplePie] using txp:feed within link form

thanks for the quick response.

i’m really unsure of what to edit, though, and have posted the plugin here. Any advice on what to edit?

global $txpcfg;
if (!class_exists('SimplePie')) require($txpcfg['txpath'].'/lib/simplepie.inc');

function feed($atts, $thing='') {
	global $txpcfg;
	$BLOGROOT = explode('/index.php', $_SERVER["PHP_SELF"]);
	$BLOGROOT = $BLOGROOT[0];
	$TXPROOT = $BLOGROOT . '/textpattern';

	$input = $thing;
	$argv = $atts;

	$feed = new SimplePie();
	$feed->set_feed_url($input);
	$feed->set_cache_location($txpcfg['txpath'] . '/lib/simplepie_cache');
	$feed->set_cache_duration(999999999); 
        $feed->set_timeout(-1);
        $success = $feed->init();

	## define some optional defaults
	if (!isset($argv['listtype']) || empty($argv['listtype'])) {
			$argv['listtype']="ul";
	} 
	if (!isset($argv['h']) || empty($argv['h'])) {
			$argv['h']="h3";
	} 
	##
	if ($success && $feed->data) {
		$flink = $feed->get_permalink();
		$ftitle = $feed->get_title();

		$output='';
		$output .= '<div class="simplepie">';
		if (!isset($argv['showtitle']) || empty($argv['showtitle']) || $argv['showtitle'] == "true") {
			if($argv['alttitle'] == -1) {
				## no title
			} elseif (isset($argv['alttitle']) && !empty($argv['alttitle'])) {

		}

		$output .= "<".$argv['listtype'].">";

				$suffix = '...';
				$short_desc = trim(str_replace("\n", ' ', str_replace("\r", ' ', strip_tags(StupefyEntities($item->get_description())))));
				$desc = substr($short_desc, 0, $argv['shortdesc']);
				$lastchar = substr($desc, -1, 1);
				if ($lastchar == '.' || $lastchar == '!' || $lastchar == '?') $suffix='';
				$desc .= $suffix;
			}

			if (isset($argv['showdesc']) && !empty($argv['showdesc']) && $argv['showdesc']==='false') {
				if (isset($argv['showdate']) && !empty($argv['showdate'])) {
					$output .= "<li><a href=\"$link\">$title</a> <span class=\"date\">" . $item->get_date($argv['showdate']) . "</span></li>";

					$output .= "<li><strong><a href=\"$link\">$title</a> <span class=\"date\">" . $item->get_date($argv['showdate']) . "</span></strong><br />$desc</li>";
				} else {
					$output .= "<li><strong><a href=\"$link\">$title</a></strong><br />$desc</li>";
				}
			}
		}

		$output .= "</".$argv['listtype'].">";;
		$output .= '</div>';
	}
	else {
		if (isset($argv['error']) && !empty($argv['error'])) $output = $argv['error'];
		else if (isset($feed->error)) $output = $feed->error;
	}

	return $output;

Re: [SimplePie] using txp:feed within link form

Nevermind! I got over my codephobia and did a bit of research and simply changed

$input = $thing;

to

$input = parse($thing);

and it worked! thanks for the pointer!
