How to add ads to the end of RSS on wordpress?

I have added a function to functions.php on my theme.

function insertAds($content) {

$content = $content.' add goes here';

return $content;}

add_filter('the_content_feed', 'insertAds');

add_filter('the_excerpt_rss', 'insertAds');

The problem is that I’m having the add displayed under each content, and not at the end of the rss page. How can I fix that?

  1. WordPress doesn’t offer a hook for what you want to do. In which element would you place the ad?

    The usual RSS-2-Feed has meta data and items (the content). There is no other element.
    See wp-includes/feed-rss2.php for details.

    Update

    Adjust the following code to your needs and put the file into your plugin directory:

    <?php
    /*
    Plugin Name: Last man adding
    Description: Adds content to the last entry of your feed.
    Version: 0.1
    Author: Thomas Scholz
    Author URI: http://toscho.de

    */
    
    if ( ! function_exists('ad_feed_content') )
    {
        function ad_feed_content($content)
        {
            static $counter = 1;
            // We only need to check this once.
            static $max = FALSE;
    
            if ( ! $max )
            {
                $max = get_option('posts_per_rss');
            }
    
            if ( $counter < $max )
            {
                $counter++;
                return $content;
            }
            return $content . <<<MY_ADDITIONAL_CONTENT
    <hr />
    <p>Place your ad here. Make sure, your feed is still
    <a href="http://beta.feedvalidator.org/">validating</a></p>
    MY_ADDITIONAL_CONTENT;
        }
    }
    add_filter('the_content_feed', 'ad_feed_content');
    add_filter('the_excerpt_rss',  'ad_feed_content');
    

    Is this the effect you had in mind? As you can see, adding content is rather easy. 🙂
