JR Tashjian

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!
<h3>General Usage</h3>
fetch_feed_cache() is the only function you will be using with this plugin. fetch_feed_cache() accepts 2 parameters.
<ol>
<li>(string) $url – This is the URL to the feed you would like to parse</li>
<li>(int) $cache_min – This is the amount of time in minutes you would like the feed cached for.</li>
</ol>
Here is an example of the plugin being used in a template:
<pre><code><?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 : ?>
 Delicious doesn't seem to be working at the moment...
 <?php endif; ?>
</ul>
</code></pre>
Remeber, every feed could be different. If you need to see the structure of the object returned just use print_r(). 
Example: <code><?php print_r(fetch_feed_cache("http://jrtashjian.com/feed/", 25)); ?></code>

Fetch Feed

Fetches an RSS feed and returns RSS as array

Stefi

It displays a list of feed items from a given feed URL. You can select cache recreation frequency, the number of displayable news and whether you want publication date, time (and in which format), an excerpt and reference to the plugin homepage displayed or not. You can also choose to have a ordered (numbered) or unordered (bullet-point) list and to open a new windows or not, when clicking on the linked items.

(1) Notes on ‘filter’ attribute/parameter:</li>
</ul>
<ol>
<li>You can enter one of more words to be able to select your feed’s items by keyword. So if you write “foo bar” you will INCLUDE ONLY those titles where ANY of the two word(s) is present and if you write “-foo -bar” you will EXCLUDE ALL those titles where any of the two words is present instead.</li>
<li>You can also mix inclusive and exclusive terms as in “foo -bar” of course (it will include only titles with “foo” and without “bar”.)</li>
<li>Search is case insensitive and searches for keywords in the titles only.</li>
<li>Wildshars, quotes and boolean are not enabled for this search. 
(2) Note on ‘num’ attribute/parameter: 
The maximum number of displayable articles/items depends on the number of articles stored into the XML page (RSS/Atom feed page) of the website you want to syndicate (i.e. if you wish to display the latest 15 items and the original feed contains 10 items only, then only 10 items will be displayed). 
(3) Note on ‘topic’ attribute/parameter: 
Not all topics are set for all countries/languages. If you select a topic for a country where this is not provided (as yet?) then the “Top stories” (the default) will be displayed instead. 
(4) Note on ‘topic’ & ‘gsearch’ attributes/parameters: 
Google (not me!) allows to search by topic OR by search-word(s). The two “filters” do not work together: if topic AND search-keys are both entered by the user, then the search-keys will be ignored and no error message will be displayed. 
(5) Note on ‘Local’ attribute/parameter: 
This option is available for Google News in English limited to Usa and Canada. It allows to enter city, region or postcode for local news results only. 
Example of shortcode with all attributes and their default values for a generic feed URL: 
[RSSjb feed=”http://feeds.feedburner.com/StefaniasBlog” filter=”” num=”5″ ltime=”” list=”ul” target=”_blank” pubdate=”false” pubtime=”false” dformat=”” tformat=”” pubauthor=”true” excerpt=”false” charex=”150″ title=”” link=”false” sort=”false” cachefeed=”3600″] 
Example of shortcode with all attributes and their default values for a Google News feed URL: 
[RSSjb location=”us” local=”” topic=”” gsearch=”” filter=”” num=”5″ ltime=”” list=”ul” target=”_blank” pubdate=”false” pubtime=”false” dformat=”” tformat=”” pubauthor=”true” excerpt=”false” charex=”150″ title=”” link=”false” sort=”false” cachefeed=”3600″]</li>
</ol>
<h3>The Future</h3>
<ul>
<li>being able to view images (and media files) too</li>
<li>more feeds for more websites</li>
<li>filter by keywords in description too (new attribute)</li>
</ul>
<h3>Interaction</h3>
<ul>
<li>Would you like to see a new feature in this plugin? Please write me here: stefonthenet@gmail.com;</li>
<li>Would you like to see a broken/orphan plugin working again? Write me anyhow, I might (hey, MIGHT) find the time to give it a look.</li>
