<h3>RSS Shortcode Output &mdash; Instructions</h3>

<div class="wpp-rss-admin-section">

<p>In order to embed RSS feeds, please use the shortcode. The base shortcode requires and URL setting and is like this:</p>

<code>[wpp_rss url="http://feeds.feedburner.com/TechCrunch/"]</code>

<p>Add additonal RSS feeds by placing commas between the feed URLs, like so:</p>

<code>[aggregation_rss url="http://feeds.feedburner.com/TechCrunch/,http://feeds.feedburner.com/TechCrunch/"]</code>

</div><div class="wpp-rss-admin-section">

<p>Additional shortcode properties include:</p>

<ul>

<li>type - Specifies the output structure of the RSS. (reg for regular output, emailfeat for featured spot in email output, and email for list/top stories spot in email template). <em>NOTE: Using type="emailfeat" or type="email" removes all other options.</em></li>

<li>items – Number of items from the feed you wish to fetch. Default is 10.</li>

<li>orderby – Order the items by date or reverse date (date or reverse_date).</li>

<li>title – Choose whether to display the title or not (true or false, defaults to true).</li>

<li>excerpt – How many words you want to display for each item’s excerpt (default is 0 or infinite, use ‘none’ to remove the excerpt).</li>

<li>read_more – Choose whether to display a read more link or not (true or false, defaults to true).</li>

<li>new_window – Choose whether to open the title link and read more link in a new window (true or false, defaults to true).</li>

<li>thumbnail – Choose whether or not you want to display a thumbnail, and if so, what size you want it to be (true or false, defaults to true, inserting a number will change the size, default is 150).</li>

<li>source – Choose whether to display the source or note (true or false, defaults to true).</li>

<li>date – Choose whether to display the publish date of the post or not (true or false, defaults to true).</li>

<li>cache – Choose how long you want the feed to cache in seconds(default is 43200, which is 12 hours).</li>

</ul>

</div>
