RSS Feed

While there are many ways to protect your content from theft but adding a link back to your post automatically using RSS feed will make a lot of real sense. With this way, people who use your RSS feed to publish your content on their own websites automatically will automatically end it up in publishing your copyright notice as well as giving you a backlink. In order to achieve this, simply add the following code to your theme’s functions.php file while you are free to customize copyright notice on line 4.

<?php
/*
Template Name: Custom Feed
*/
$numposts = 5;
function yoast_rss_date( $timestamp = null ) {
  $timestamp = ($timestamp==null) ? time() : $timestamp;
  echo date(DATE_RSS, $timestamp);
}
function yoast_rss_text_limit($string, $length, $replacer = '...') {
  $string = strip_tags($string);
  if(strlen($string) > $length)
    return (preg_match('/^(.*)\W.*$/', substr($string, 0, $length+1), $matches) ? $matches[1] : substr($string, 0, $length)) . $replacer;
  return $string;
}
$posts = query_posts('showposts='.$numposts);
$lastpost = $numposts - 1;
header("Content-Type: application/rss+xml; charset=UTF-8");
