UPDATE: checkout the "addons" Wordpress plugin to get this functionality.

The use of ads in RSS Feeds hasn't been one I've explored much. Whilst there is an option in the "inline ads" section to show that ad type in the RSS Feed, it doesn't offer much in the way of flexibility.

Inline ads are dealt with entirely automatically (they are placed in the post using the Wordpress "content" filter), so there's no setup required beyond what's on the admin settings page. You can test it out by configuring the admin options then placing a default ad to see how it appears within blog posts.

You can still use OIO to manage ads in the RSS Feed (eg. creating a specific banner ad zone for it), but you'd need to create a small plugin to insert the ad zone into the RSS Feed in the manner you'd like.

Below is a very simple example of how to insert a banner zone (ID #1) on to the end of the RSS Feed.

/*
Plugin Name: OIO RSS Feed
Description: Add an ad zone to the RSS Feed
Version: 1.00
*/
//OIO ad code goes within this function
function oiopub_feed_wrapper($content) {
$zone_id = 1;
if(is_feed() && function_exists('oiopub_banner_zone')) {
$content .= oiopub_banner_zone($zone_id, 'center', '', 1);
}
return $content;
}
//add to feed
add_filter('the_content', 'oiopub_feed_wrapper');


Ok, How can I make sure it's showing up correctly. I've activated the plugin (changed it to a Zone 3) created and enabled a Zone 3 and put in a default image and a default html ad.

I've subscribed to the feed to see if it shows up and I've yet to see anything. Is there a way I can tell what's going on or if it will show up. very important for an ad deal I'm working! thanks!!

Sure, here it is

There are also some google ads down there being added by feedburner.

Ok Simon, thanks! I've got it working now with the code you provided above. Also a not to anyone else not familiar with php, you'll need to add opening/closing php.

Here's what mine looked like in the end for a position 3 banner ad shown only at the end of each post in the feed.

<?php
/*
Plugin Name: OIO RSS Feed
Description: Add an ad zone to the RSS Feed
Version: 1.00
*/
//OIO ad code (php)
function oiopub_feed_php($content) {
$zone_id = 3;
if(is_feed() && function_exists('oiopub_banner_zone')) {
$content .= oiopub_banner_zone($zone_id, 'center', '', 1);
}
return $content;
}
//OIO ad code (js)
function oiopub_feed_js($content) {
global $oiopub_set;
$zone_id = 3;
if(is_feed()) {
$content .= '<script type="text/javascript" src="' . $oiopub_set->plugin_url . '/js.php?type=banner&zone=' . $zone_id . '"></script>';
}
return $content;
}
//add to feed (using php in this example)
add_filter('the_content', 'oiopub_feed_php');
?>


Hmmm no there shouldn't be anything different that would affect it.

An obvious question I know, but is the plugin definitely active? Also, is banner ad zone 3 "enabled" in the settings? (just in case something got scrambled somehow during the upgrade, although it shouldn't have)

I just checked the feed again, and I can see an ad under each post in the feed now. Did you manage to sort it out, or is there still a problem with flash?

Oh, btw, the stat tracker doesn't seem to be picking up the clicks from the RSS banner ad either.

OK, I'm not exactly sure what I need to do on my end. Do I need to download the oiopublisher zip and replace the output.php file?

On the stats, getting the clicks is the most important to the advertiser, so I'd want to do it that way.

btw. I also have an adsense block in the feed. How does Google do it? When I look at the adsense results I see impressions and clicks. I just wanted to mention that in case it could help work backwards on something for OIO.

btw2. I'm thinking feed type ads and 'embeddable' ads are gonna start being more in demand. Especially with sites like twitter, friendfeed, tumblr and posterous and Google Reader Followers. I'd be interested in being able to embed something into my twitter/freindfeed/posterous posts. something with the same features as OIO!

Thanks Simon!!

Ok, it's been awhile (apologies) but I did replace the output file and the bullet is gone. (Thanks!)

How would I go about using the javascript in the feed plugin? I tried just replacing the function with the javascript. should that work?

Thanks once again Simon!

I try to avoid buying plugins myself and make them too but sometimes thats just stupid especially when there are plugins like this.

I think everything is covered. Some improvements could be made but then thats a fact with everything in the world so don't let it put you off.

I'm using it to sell space on www.webtechglobal.co.uk

Thanks
