Tronquer les descriptions du flux rss de Freeglobes

Salut,

Qui pourrait me dire comment tronquer les descriptions du flux rss proposé par défaut dans Freeglobes ?
En effet, les longues descriptions y sont reprises intégralement et ça me pose des problèmes...

J'imagine que ça se passe soit dans rss.php :

Code:
<?php

/*
*	Displays RSS feed of the website
*/

include (dirname(__FILE__).'/init.php');
// RSS generator PHP class
include (SCRIPT_ROOT_PATH.'/class/class.rss_generator.php');

$lm =& get_manager('link');

$criteria = new Criteria("state",4,'=');
$criteria->setOrder('DESC');
$criteria->setSort('id');
$criteria->setLimit(1000);

$cols = array('id','name','url','description','image','date');
$sites = $lm->getObjects($criteria,$cols);

$rss = new rssGenerator_channel();
$rss_channel->docs = 'http://blogs.law.harvard.edu/tech/rss' ;
$rss_channel->pubDate = date('r') ;
$rss_channel->lastBuildDate = date('r') ;
$rss_channel->ttl = 120 ;
$rss_channel->title = utf8_encode($CONFIG['site_name']);
$rss_channel->link = $CONFIG['site_url'];
$rss_channel->description = utf8_encode($CONFIG['site_name']);
$rss_channel->language = 'fr-fr';
$rss_channel->generator = 'FreeGlobes';
$rss_channel->managingEditor = $CONFIG['site_mail'];
$rss_channel->webMaster = $CONFIG['site_mail'];

if (count($sites) != 0)
{
	$re =& MyRewriteEngine::getInstance();
	foreach($sites as $site)
	{
		$item = new rssGenerator_item();
		$item->pubDate = date('r',strtotime($site->getVar('date'))) ;
		$item->title = '<![CDATA[ '.utf8_encode($site->getVar('name')).' ]]>';
		$item->description = '<![CDATA[ '.utf8_encode($site->getVar('description')).' ]]>';
		$item->link = $CONFIG['site_url'].'/'.$re->buildUrl('single',array('id' => $site->getVar('id'), 'name' => $site->getVar('name')));
		
		$image = $site->getVar('image');
		if(!empty($image) && $image != 'http://')
		{
			$filesize = 0;
			$item->enclosure_url = $image;
			$item->enclosure_length = $filesize;
		}
	
		$rss_channel->items[] = $item;
		unset($item);
	}
}

$rss_feed = new rssGenerator_rss();
$rss_feed->encoding = 'UTF-8';
$rss_feed->version = '2.0';

header('Content-Type: text/xml');
echo $rss_feed->createFeed($rss_channel);

include(dirname(__FILE__).'/disconnect.php');
?>

Soit dans class.rss_generator.php :

J'ai beau bidouiller, j'y connais rien du tout en php...

Est-ce que quelqu'un connait la solution ?
Merci.
 
Dans rss.php tu as :
Code:
$item->description = '<![CDATA[ '.utf8_encode($site->getVar('description')).' ]]>';
A remplacer par
Code:
$nombre_de_caractere_que_tu_veux = 100;
$item->description = '<![CDATA[ '.utf8_encode(substr($site->getVar('description'), 0, $nombre_de_caractere_que_tu_veux)).' ]]>';
 
Je suis pas sûr que ça suffise avec substr parce que dans le cas où la description contient du html, ça va avoir des effet un peu aléatoires non ?
 
Bonjour,

Merci, ça fonctionne.
Je n'aurais pas de html dans mon cas mais si il était possible d'éviter de couper au milieu d'un mot et de terminer par "...", ce serait le top !
Encore merci.
 
Essaie comme ceci pour terminer avec ...

Code:
$item->description = '<![CDATA[ '.utf8_encode(substr($site->getVar('description'), 0, $nombre_de_caractere_que_tu_veux." ...")).' ]]>';
 
Code:
function truncate($string, $max, $rep = '...') {
	$stringlength = strlen($string);
	$string = $string." ";
	$string = substr($string,0,$max);
	$string = substr($string,0,strrpos($string,' '));
	if($stringlength > $max)
		$string = $string.$rep;
	return $string;
}
 
attention, la recherche du dernier espace précédent la longueur de texte à récupérer peut très bien couper au milieu d'une balise image, <a href>, <div class="">,etc... :cry:
Et après, tu reviendras sur wri demander pourquoi google invente des url :wink:
 
Salut à tous,

Etant donné que je comprends rien au php et que je n'aurais pas de html, je vais quand même couper à l'arrache avec les "...".
Merci à tous de l'aide proposée, ça m'arrange bien...
