<p>The RSS Feed checker looks through your blogroll for links with rss feeds and then stores the name and url of the latest article.<br />
The Links RSS Enhanced widget then displays the latest links in descending order.<br />
The idea for the widget comes from the blogroll widget on blogger.</p>
<h3>Technical section</h3>
<p>The plugin will create an extra table in your wordpress database to store the latest feed updates,<br />
this will be called links_rss with the prefix for your database e.g. wp_links_rss</p>
<p>A Cron (schedule) is created to run every 30 minutes and process links. Note that Cron in WordPress<br />
depends on hits, your WordPress website receives. So playing with this plugin within an offline<br />
environment (MAMP, XAMPP, WAMP etc.) without anyone or anything triggering the scheduling by<br />
sending requests to the WordPress page won’t produce any results if you do not trigger it by<br />
yourself.</p>

<p>For people who maintain their Web site or blog using the WordPress blog content management system,<br />
blogroll-links is an open source WordPress plugin that uses WordPress’ built-in Blogroll feature and presents links to friends’ home pages and own pages on social networking sites using XFN in the links.</p>
<p>Features of this plugin</p>
<ul>
<li>It can show the links by category in blog posts and WordPress Pages.</li>
<li>It uses WordPress’ standard built-in Blogroll links database. There is no hassle of another list of links to maintain.</li>
<li>It can be used to show only the links assigned to a particular category, by stating the category slug as defined in that category’s setting in WordPress.</li>
<li>It honors the Show/Hidden setting as defined for each link in WordPress.</li>
<li>It displays the link in the same window or new window, as specified for each link in WordPress.</li>
</ul>
<p>To learn more about this plugin, please read my blog post about it titled<br />
<a href="http://www.rajiv.com/blog/2008/02/10/blogroll-links/" rel="nofollow ugc">Social Graphs API: WordPress Plugin: Blogroll Links</a></p>
<p><strong>Examples</strong></p>
<p>See this plugin in action at the following Posts and Pages powered by WordPress:</p>
<p><a href="http://www.rajiv.com/friends/" rel="nofollow ugc">www.rajiv.com/friends/</a></p>
<p>The two lists, first one of links to my own pages on various social networking sites and the second one of links to some of my friends’ pages are generated by this plugin. Yes, those social networks’ logo pictures are also taken by the plugin from the WordPress standard Blogroll links. Code:</p>
<pre><code><h3>My Pages on Social Networking Sites</h3>
</code></pre>
<p>Syntax:</p>
<pre><code>[blogroll-links categoryslug="rajiv-web" sortby="link_name" sortorder="desc"]
</code></pre>
<p>Old syntax for legacy support:<br />
    </p>
<pre><code><h3>Web Sites of Some People I Know</h3>
</code></pre>
<p>Syntax:</p>
<pre><code>[blogroll-links categoryslug="people" sortby="link_name" sortorder="desc"]
</code></pre>
<p><a href="http://www.rajiv.com/charity/" rel="nofollow ugc">www.rajiv.com/charity/</a></p>
<p>This list of charitable organizations with brief descriptions is generated by the plugin. Code:</p>
<p>Syntax:</p>
<pre><code>[blogroll-links categoryslug="charity"]
</code></pre>
<p><a href="http://www.rajiv.com/blog/2004/08/02/search-engines/" rel="nofollow ugc">www.rajiv.com/blog/2004/08/02/search-engines/</a></p>
<p>This list of search engines is maintained as Blogroll links in WordPress. Code:</p>
<p>Syntax:</p>
<pre><code>[blogroll-links categoryslug="search-engines"]
</code></pre>
<p><a href="http://www.rajiv.com/" rel="nofollow ugc">www.rajiv.com/</a></p>
<p>The featured links shown under the “What’s featured here?” section shows the links I’ve categorized as featured in WordPress’ Blogroll links. Code:</p>
<pre><code><a title="featured" name="featured"></a>

<h2>What's featured here?</h2>
</code></pre>
<p>Syntax:</p>
<pre><code>[blogroll-links categoryslug="featured" sortby="link_name" sortorder="desc"]
</code></pre>
<p>Thanks to Dave Grega, Adam E. Falk (xenograg) for their contributions to this code.</p>
