Adds a simple to use [rss] shortcode with a couple of options:
<ul>
<li>feed, to put in the feed URL</li>
<li>num, to specify the number of items to show, defaults to 5</li>
<li>excerpt (true|false), whether to show an excerpt or not, defaults to true</li>
<li>target (defaults to none), to make links open in a new page (might break your html validity if under a strict doctype)</li>
</ul>
Example use:
[rss feed=”http://yoast.com/feed/” num=”10″ excerpt=”false”]
Or:
[rss feed=”http://yoast.com/feed/” num=”5″ excerpt=”true” target=”_blank”]

RSS Shortcode

Simple plugin to show RSS feeds in posts and pages using a shortcode.

Display feeds in your blog, using PHP, a Widget or Shortcode. The plugin uses only standard WordPress functionality, so no external libraries are required. For older versions of WordPress, the built-in <a href="https://magpierss.sourceforge.net/" rel="nofollow ugc">MagpieRSS library</a> is used. For WordPress 2.8 and newer, there is a setting available to enable the built-in <a href="https://simplepie.org/" rel="nofollow ugc">SimplePie library</a> for parsing feeds.
As with all other content you publish, make sure you are allowed to (re-)publish the content of the feeds you are about to import!
You can insert the following code into a PHP plugin or in a template, for example <code>sidebar.php</code> or <code>single.php</code>:
Example: 
 <?php RSSImport(10, ‘https://bueltge.de/feed/’); ?>
This is the minimal code needed for using the plugin. The plugin accepts a number of parameters for customizing the feed content import. See below for the full list of available parameters. You can also use any of the parameters with Shortcode in posts and pages.
Example Shortcode: 
 [RSSImport display=”5″ feedurl=”https://bueltge.de/feed/” use_simplepie=”true”]
For all (bool) parameters you can either use the strings <code>true</code> and <code>false</code> or the integer values <code>1</code> and <code>0</code>.

</ol>
If pagination is enabled, it adds a <code>div</code> with the class <code>rsspaging</code> to enable easier styling with CSS. You can also style the previous and next links, which have the classes: <code>rsspaging_prev</code> and <code>rsspaging_next</code>.
You can use any of the parameters in the php function <code>RSSImport()</code> in your templates or with the Shortcode <code>[RSSImport]</code> in posts and pages.
<h4>Examples</h4>
Using the PHP function with many parameters:
<pre><code>RSSImport(
 $display = 5, $feedurl = 'https://bueltge.de/feed/', 
 $before_desc = '', $displaydescriptions = false, $after_desc = '', $html = false, $truncatedescchar = 200, $truncatedescstring = ' ... ', 
 $truncatetitlechar = '', $truncatetitlestring = ' ... ', 
 $before_date = ' ', $date = false, $after_date = '', 
 $before_creator = ' ', $creator = false, $after_creator = '', 
 $start_items = '<ul>', $end_items = '</ul>', 
 $start_item = '<li>', $end_item = '</li>'
);
</code></pre>
Please note that for the PHP function the parameters are expected in the order in which they are defined in the above list. Thus if you skip one parameter, you will also have to skip all of the subsequent parameters.
Using Shortcode with several parameters:
<pre><code>[RSSImport display="10" feedurl="https://your_feed_url/" 
displaydescriptions="true" html="true" 
start_items="<ol>" end_items="</ol>" paging="true" use_simplepie="true"]
</code></pre>
Add a “more” link to the output:
<pre><code>RSSImport(
 $display = 5,
 $feedurl = 'https://bueltge.de/feed/', 
 $before_desc = '',
 $displaydescriptions = true,
 $after_desc = ' <a href="%href%" target="_blank">show more</a>'
);
</code></pre>
or
<pre><code>[RSSImport feedurl="https://wordpress.org/news/feed/" after_desc=" <a href='%href%' target='_blank'>show more</a>" displaydescriptions="true" use_simplepie="true"]
</code></pre>
Enable Thumbnail Pictures:
<pre><code>RSSImport(
 $display = 5,
 $feedurl = 'https://bueltge.de/feed/',
 $before_desc = '<img src="%picture_url%" alt="">',
 $displaydescriptions = true
);
</code></pre>
or
<pre><code>[RSSImport feedurl="https://wordpress.org/news/feed/" displaydescriptions="true" before_desc="<div><img src='%picture_url%' width='50px' alt='' style='float:left;' />" after_desc="</div>" use_simplepie="true"]
</code></pre>
