There are all kinds of plugins and code out there for posting a Twitter feed to a website. Most of them ignore that Twitter only allows 150 requests per hour. This often results in Tweets not displaying for websites that get any decent number of hits.

Caching the Twitter Feed in WordPress

The solution is to cache the Twitter feed.

I figured it may be helpful however to post an example of an easy code built on the Nashville music venue, 12th and Porter website, that you can copy and paste and give some brief explanation.

The Code

<pre>

<div id="jstweets"></div>

<?php

include('twitter-cache.php');

$cache = new JG_Cache(dirname(__FILE__). '/cache');

$data = $cache->get('tweets');

if ($data === FALSE)
{
$data = file_get_contents("http://twitter.com/statuses/user_timeline.json?screen_name=12th_and_porter&count=3");
$cache->set('tweets', $data);
}

?>

<script>
jQuery(function(){
var data = &lgt;?php echo $data; ?>;

jQuery.each(data, function(i,item){
ctd = item['created_at'];
cta = item['id'];
ct = item.text;
ct = ct.replace(/http:\/\/\S+/g, '<a href="$&" target="_blank">$&</a>');
ct = ct.replace(/\s(@)(\w+)/g, ' @<a onclick="javascript:pageTracker._trackPageview("/outgoing/twitter.com/");" href="http://twitter.com/$2" target="_blank">$2</a>');
ct = ct.replace(/\s(#)(\w+)/g, ' #<a onclick="javascript:pageTracker._trackPageview("/outgoing/search.twitter.com/search?q=%23");" href="http://search.twitter.com/search?q=%23$2" target="_blank">$2</a>');
jQuery("#jstweets").append(' <div&gtl;<span>'+ ctd + '</span>' + ct + ' <a target="_blank" href="http://twitter.com/12th_and_porter/status/'+cta+'">View &raquo;</a></div> ');
});
});
</script>

</pre>
