Hi, Im trying to integrate my twitter function into wordpress via a shortcode, now everything works fine except it's not allowing me to set a number of tweets to display and is only allowing the 1 tweet to be displayed.
Here's the twitter function im using to pull the tweets;

<?php
class Twitter
{
public $tweets = array();
public function __construct($user, $limit = 5)
{
$user = str_replace(' OR ', '%20OR%20', $user);
$feed = curl_init('http://search.twitter.com/search.atom?q=from:'. $user .'&rpp='. $limit);
curl_setopt($feed, CURLOPT_RETURNTRANSFER, true);
curl_setopt($feed, CURLOPT_HEADER, 0);
$xml = curl_exec($feed);
curl_close($feed);
$result = new SimpleXMLElement($xml);
foreach($result->entry as $entry)
{
$tweet = new stdClass();
$tweet->id = (string) $entry->id;
$user = explode(' ', $entry->author->name);
$tweet->user = (string) $user[0];
$tweet->author = (string) substr($entry->author->name, strlen($user[0])+2, -1);
$tweet->title = (string) $entry->title;
$tweet->content = (string) $entry->content;
$tweet->updated = (int) strtotime($entry->updated);
$tweet->permalink = (string) $entry->link[0]->attributes()->href;
$tweet->avatar = (string) $entry->link[1]->attributes()->href;
array_push($this->tweets, $tweet);
}
unset($feed, $xml, $result, $tweet);
}
public function getTweets() { return $this->tweets; }
}
?>Here's the shortcode im using
<?php
function twitter_feed($atts, $content = null) {
extract(shortcode_atts(array(
"user" => '',
"limit" => ''
), $atts));
$feed = new Twitter($user , $limit);
$tweets = $feed->getTweets();
foreach ($tweets as $tweet) {
return '<ul><li>'. $tweet->content .' by <a href="http://twitter.com/'. $tweet->user .'">'. $tweet->author .'</a></li></ul>';
}
}
add_shortcode("twitter", "twitter_feed");
?>Example Shortcode
[twitter user="YourTwitterUserName" limit="5"]
As I said above this code works fine apart from the tweet limit it, only ever pulls 1 tweet.
Now I've tried putting the code directly into the theme to see if it was a problem with the function but it works fine, so I must be doing something wrong in the shortcode. Any idea's folks?
