Help with minor Joomla RSS Feed Component modification

[Hersh]

I have a full-text RSS component for Joomla that I was trying to modify. I wanted to be able to truncate the article to a given number of words and place a link at the end for the rest of the article.

 

I paid a freelancer to do this but he did half the work and dipped. I just need help inserting the URL of the feed at the end of the article, post truncation.

 

This is basically what he added to the top of the post.php file. I should note also that the "$ending" tag doesn't seem to function either since there is no "..." appended to the end of articles posted, when I tested it.

	public function truncate($text, $length = 200, $ending = '...', $exact = true, $considerHtml = false) {
	if ($considerHtml) {
		// if the plain text is shorter than the maximum length, return the whole text
		if (str_word_count(preg_replace('/<.*?>/', '', $text)) <= $length) {
			return $text;
		}
		// splits all html-tags to scanable lines
		preg_match_all('/(<.+?>)?([^<>]*)/s', $text, $lines, PREG_SET_ORDER);
		$total_length = str_word_count($ending);
		$open_tags = array();
		$truncate = '';
		foreach ($lines as $line_matchings) {
			// if there is any html-tag in this line, handle it and add it (uncounted) to the output
			if (!empty($line_matchings[1])) {
				// if it's an "empty element" with or without xhtml-conform closing slash (f.e. <br/>)
				if (preg_match('/^<(\s*.+?\/\s*|\s*(img|br|input|hr|area|base|basefont|col|frame|isindex|link|meta|param)(\s.+?)?)>$/is', $line_matchings[1])) {
					// do nothing
				// if tag is a closing tag (f.e. </b>)
				} else if (preg_match('/^<\s*\/([^\s]+?)\s*>$/s', $line_matchings[1], $tag_matchings)) {
					// delete tag from $open_tags list
					$pos = array_search($tag_matchings[1], $open_tags);
					if ($pos !== false) {
						unset($open_tags[$pos]);
					}
				// if tag is an opening tag (f.e. <b>)
				} else if (preg_match('/^<\s*([^\s>!]+).*?>$/s', $line_matchings[1], $tag_matchings)) {
					// add tag to the beginning of $open_tags list
					array_unshift($open_tags, strtolower($tag_matchings[1]));
				}
				// add html-tag to $truncate'd text
				$truncate .= $line_matchings[1];
			}
			// calculate the length of the plain text part of the line; handle entities as one character
			$content_length = str_word_count(preg_replace('/&[0-9a-z]{2,8};|&#[0-9]{1,7};|[0-9a-f]{1,6};/i', ' ', $line_matchings[2]));
			if ($total_length+$content_length> $length) {
				// the number of characters which are left
				$left = $length - $total_length;
				$entities_length = 0;
				// search for html entities
				if (preg_match_all('/&[0-9a-z]{2,8};|&#[0-9]{1,7};|[0-9a-f]{1,6};/i', $line_matchings[2], $entities, PREG_OFFSET_CAPTURE)) {
					// calculate the real length of all entities in the legal range
					foreach ($entities[0] as $entity) {
						if ($entity[1]+1-$entities_length <= $left) {
							$left--;
							$entities_length += str_word_count($entity[0]);
						} else {
							// no more characters left
							break;
						}
					}
				}
				$truncate .= substr($line_matchings[2], 0, $left+$entities_length);
				// maximum lenght is reached, so get off the loop
				break;
			} else {
				$truncate .= $line_matchings[2];
				$total_length += $content_length;
			}
			// if the maximum length is reached, get off the loop
			if($total_length>= $length) {
				break;
			}
		}
	} else {
		if (str_word_count($text) <= $length) {
			return $text;
		} else {
			$truncate = substr($text, 0, $length - str_word_count($ending));
		}
	}
	// if the words shouldn't be cut in the middle...
	if (!$exact) {
		// ...search the last occurance of a space...
		$spacepos = strrpos($truncate, ' ');
		if (isset($spacepos)) {
			// ...and cut the text in this position
			$truncate = substr($truncate, 0, $spacepos);
		}
	}
	// add the defined ending to the text
	$truncate .= $ending;
	if($considerHtml) {
		// close all unclosed html-tags
		foreach ($open_tags as $tag) {
			$truncate .= '</' . $tag . '>';
		}
	}
	return $truncate;
}

 

 

 

I have attached the whole file as well if you want to see the rest.

It seems like he simply added this script to the top of the file. *Smh*

 

http://codextension.com/information/65.html

 

 

I forgot to mention by the way, the script originally automatically added the link to the source article:

	if($link_original==1){
		if(strlen($ret->fullText))
			$ret->fullText.="<p><a href='". $item->link."' target='_blank'>".$text_link_original."</a></p>";
		else
			$ret->introText.="<p><a href='". $item->link."' target='_blank'>".$text_link_original."</a></p>";
	}

The problem is that it gets truncated with the rest of the article now.
