Flux RSS des articles

Baroque Cafe

Salut,

Il faudrait pouvoir configurer une limitation de la description item pour le flux rss des articles. Genre dans l'admin/Option d'affichage.
Perso j'ai fait un petit hack mais bon ...

[== PHP ==]
	public function getRssArticles() {

	function truncate($string, $max_length = 100, $replacement = '...', $trunc_at_space = false)
{
	$max_length -= strlen($replacement);
	$string_length = strlen($string);
	
	if($string_length <= $max_length)
		return $string;
	
	if( $trunc_at_space && ($space_position = strrpos($string, ' ', $max_length-$string_length)) )
		$max_length = $space_position;
	
	return substr_replace($string, $replacement, $max_length);
}
		# Initialisation
		$last_updated = '197001010100';
		$entry_link = '';
		$entry = '';
		if($this->mode == 'tag') {
			$title = $this->aConf['title'].' - '.L_PAGETITLE_TAG.' '.$this->cible;
			$link = $this->urlRewrite('?tag/'.$this->cible);
		}
		elseif($this->cible) { # Articles d'une catégorie
			$catId = $this->cible + 0;
			$title = $this->aConf['title'].' - '.$this->aCats[ $this->cible ]['name'];
			$link = $this->urlRewrite('?categorie'.$catId.'/'.$this->aCats[ $this->cible ]['url']);
		} else { # Articles globaux
			$title = $this->aConf['title'];
			$link = $this->urlRewrite();
		}
		# On va boucler sur les articles (si il y'en a)
		if($this->plxRecord_arts) {
			while($this->plxRecord_arts->loop()) {
				# Traitement initial
				if($this->aConf['feed_chapo']) {
					$content = $this->plxRecord_arts->f('chapo');
					if(trim($content)=='') $content = $this->plxRecord_arts->f('content');
				} else {
					$content = $this->plxRecord_arts->f('chapo').$this->plxRecord_arts->f('content');
				}
				$content .= $this->aConf['feed_footer'];
				$artId = $this->plxRecord_arts->f('numero') + 0;
				$author = $this->aUsers[$this->plxRecord_arts->f('author')]['name'];
				# On check la date de publication
				if($this->plxRecord_arts->f('date') > $last_updated)
					$last_updated = $this->plxRecord_arts->f('date');
