Create a custom author feed

Using rah_external_output you can create just about any feed you would want. I needed to create a feed for a specific author.

Let’s get started

First, create a new output with a Content Type of text/xml.

The Textpattern tags I would use to get the articles for this author are:

<txp:article_custom 
allowoverride="0" 
limit="10" 
pgonly="0" 
author="AUTHORNAME" 
section="articles">

I can then add the code needed to create feed items for each of these articles. This could be in a form or to keep things simple used within a txp:article container tag.

Feed items

<item>
<title><txp:title /></title>
<description>
 <![CDATA[
  <txp:body />
 ]]>
</description>
<link><txp:permlink /></link>
<pubDate><txp:posted format="%a, %d %b %G %T %Z" /></pubDate>
<dc:creator><txp:author /></dc:creator>
<guid><txp:permlink /></guid>
</item>

The body could be replaced with excerpt if desired.

Final code

Now we need to add the remaining RSS feed to get the following:

<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:atom="http://www.w3.org/2005/Atom" >
<channel>
 <generator>http://textpattern.com/</generator>
 <title><txp:site_name /></title>
 <link><txp:link_to_home /></link>
 <description><txp:site_slogan/></description>
 <pubDate><txp:php>echo strftime( "%a, %d %b %G %T %Z" );</txp:php></pubDate>
 <atom:link href="<txp:site_url/>?rah_external_output=OUTPUT_NAME" rel="self" type="application/rss+xml" />
 <txp:article_custom allowoverride="0" limit="10" pgonly="0" author="AUTHORNAME" section="articles">
<item>
<title><txp:title /></title>
<description>
 <![CDATA[
  <txp:body />
 ]]>
</description>
<link><txp:permlink /></link>
<pubDate><txp:posted format="%a, %d %b %G %T %Z" /></pubDate>
<dc:creator><txp:author /></dc:creator>
<guid><txp:permlink /></guid>
</item>
</txp:article_custom>
</channel>
</rss>

Note: It’s important to remember that the AUTHORNAME is the Author’s username, and OUTPUT_NAME should be the name given when creating the rah_external_output item.
