內容簡介
此外掛是用來擷取與快取 RSS 資料以供在樣板中使用。
您可以傳遞您想要回傳的提要 (feed) 網址以及您想要快取的分鐘數。此外掛會將 RSS xml 快取並以物件的方式回傳，您可以透過迴圈的方式做進一步的處理，然後輸出在您的網站上。
版本 1.5 新增:
– 修正因為錯誤而每次都擷取並快取提要 (feed) 的問題。Credit: Binny V A (http://www.bin-co.com/blog/) – 謝謝他！
一般用法
fetch_feed_cache() 是此外掛唯一您需使用的函式。fetch_feed_cache() 接受 2 個參數：
(string) $url – 您想要解析的提要 (feed) URL
(int) $cache_min – 您想要快取的時間 (以分鐘為單位)
以下是此外掛在樣板中的實際範例:
<?php $xml = fetch_feed_cache("http://jrtashjian.com/feed/", 60); ?>
<h3><?=$xml->channel->title?></h3>
<ul>
<?php if( ! empty($xml)) : ?>
<?php foreach($xml->channel->item as $item) : ?>
<li><a href="<?=$item->link?>"><?=$item->title?></a></li>
<?php endforeach; ?>
<?php else : ?>
<p>Delicious doesn't seem to be working at the moment...</p>
<?php endif; ?>
</ul>
請注意，每一個提要 (feed) 都可能不同。如果您需要查看回傳的物件結構，請使用 print_r()。
範例: <?php print_r(fetch_feed_cache("http://jrtashjian.com/feed/", 25)); ?>

原文外掛簡介
This plugin was created to retrieve and cache an RSS feed for use in a template.
What you do is pass the url to the feed you would like returned and the number of minutes you would like the feed cached for. The
plugin will cache the RSS xml and return the feed as an object which you can loop through and output however you please.
New As Of Version 1.5:
– Fixed a typo that caused the feed to be retrieved and cached every time. Credit: Binny V A (http://www.bin-co.com/blog/) – Thanks man!
General Usage
fetch_feed_cache() is the only function you will be using with this plugin. fetch_feed_cache() accepts 2 parameters.
(string) $url – This is the URL to the feed you would like to parse
(int) $cache_min – This is the amount of time in minutes you would like the feed cached for.
Here is an example of the plugin being used in a template:
channel->title?>
- title?>
channel->item as $item) : ?>
Delicious doesn't seem to be working at the moment...
Remeber, every feed could be different. If you need to see the structure of the object returned just use print_r().
Example:
