The AdSense revenue sharing plugin for WordPress-MU will allow you, the owner of a WPMU site, to share Adsense revenue with your users. You can set the percentage of your share (default is 20%) and enter your AdSense publisher code via the ‘Site Admin‘ backend panel.

The user can enter his Adsense publisher code in the ‘Options‘ menu:

Download: adsense-share-mu-123.zip

Current version: 1.2.3 (view change log below)

Installation: extract the adsense-share-mu.php file and upload it to the mu-plugins directory.

How to use?

Go to ‘Site Admin‘ -> ‘Adsense share‘ and set your Adsense share and your Adsense publisher code.

There are two option to insert Google Adsense ads and they can be used together:

  1. allow users to insert an Adsense widget to their sidebar (that is the easy and simple way). All your users will have to do is drag the ‘Google Adsense‘ widget to the sidebar, click the configuration icon and enter their google_ad_client ID.
  2. hard code ads into the themes.

The second method needs some explanations. Since Google is constantly changing the structure of the ads script and adding new features, I decided that I will not deal with the ad code except for the google_ad_client which is the Adsense publisher code.

To insert ads to your themes you should log into your Google Adsense account and select the product, ad type, ad format and colors, corners style, channels and whatever Google allows you to select. Once you are done you will get a code looking something like this:

<script type="text/javascript"><!--
google_ad_client = "pub-01234567890";
google_ad_width = 728;
google_ad_height = 90;
google_ad_format = "728x90_as";
google_ad_type = "text_image";
//2007-10-07: Demo
google_ad_channel = "1234567890";
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

Simply copy this code and paste it wherever you want in your theme files. Note the second line starting with google_ad_client and ending with “pub-01234567890″;. The second part is your Adsense publisher code. If we don’t change that code you will get all the revenue from the ads and your user will not be happy. So we want to enter a piece of code that will iterate between the publishers codes. This is done by replacing the “pub-01234567890″; part with a simple line of code:


<?php get_adsense_code(); ?>;

if we want to be on the safe side we can add a check for the function:


<?php if (function_exists('get_adsense_code')) {get_adsense_code();} ?>;

So now the Adsense code looks like this:


<script type="text/javascript"><!--
google_ad_client = <?php if (function_exists('get_adsense_code')) {get_adsense_code();} ?>;
google_ad_width = 728;
google_ad_height = 90;
google_ad_format = "728x90_as";
google_ad_type = "text_image";
//2007-10-07: Demo
google_ad_channel = "1234567890";
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

If you want to ad the ads only to your themes and not allow the users to ad the widget, there is a little hack which involves editing the plugin file. Open the adsense-share-mu.php file and look at line 14. If you change the no_widgettruetrue parameter to ‘true‘ the widget will not be available.

    As trackback don’t seem to be published, I just post a special thanks for your work.

    I setup the plugin last night, and everything was done in 5 min.

    Just one thing : the made the next line of the google code to be on the same line… Nothing very important, in fact.

    I keep you inform if I get a problem.

    Hi,

    I was just wondering, as it is a bit hard to explain to all user the AdSense rules, why not add a feature that would not display ads from one user when visiting his blog ?

    I don’t know how you can do that, maybe by checking if the user is logged in (but you may have problem if the user visit other blogs…), or maybe with a cookie….

    Well, that’s just seems important to me at the moment, but I don’t know how to solve that.

    Thanks for a great plugin

    This works a treat until you have more than one google ad unit on a page.

    If you have more than one ad unit in your template and each time it calls get_adsense_code() you could end up with two ad units u sing different publisher id’s which is against the Adsense ToC’s.

    I am sure there are ways round this but thought it was worth pointing out.

    Greg,

    Before I started to work on the plugin I asked Google Adsense support about it. My question was:
    “Can I place ads with two different publisher ids on the same page?”

    Their answer:
    “This does comply with our policies”

    I have the writing on record if you want it.

    Hey Greg, Elad,

    A simple workaround to the problem would be to store the publisher’s code into a variable, ie.,

    $pubcode=get_adsense_code();

    then use $pubcode in replacement with get_adsense_code() function.

    However, you’ll prob. need to get into get_adsense_code() function to return the publisher’s code, rather than echoing it out.

    Will be implementing your plugin on my parenting tips website!

    Steve

    I did exactly that – well almost.

    I have modified the plugin so the user can enter an adsense channel aswell as their own colors, using a default set of colors if none are entered. I have then at the top of each template I call a routine in the plugin which sets some javascript vars and these are then applied to all adsense units used on the page.

    I am neither a php or wordpresss expert hence my hack is not pretty so I have not gone public with it but it works for my needs.

    Elad, I’m glad that is the case, I had heard that someone else had been told the same thing but knowing Google I tend to urge on the side of caution:)

    This is a nice plugin.

    So when I am a sideadmin, I have blog.com and I have a user that has user.blog.com and he uses my setup adsense, he get’s a share of this ?

    Is this shown somewhere btw, what his share is over a month ?

    Now it would be possible that such a users sets this own adsense in this blog, that is not nice ofcourse.

    In such a case you need to add your adsense in the templates for sure, but a backwards compatible system where if the user adds adsense in a plugin way that the site admin get’s automaticly 20% of it ?

    If that woukd be possible, it won’t I think, that would be ideal !

    Keep up the good work :)

    Mattz, the bloggers profits are not shown to the site admin. WordPress-Mu does not allow JS to be inserted so the bloggers can not place Adsense ads on their blogs.

    Kaja, there is only one widget. You can add more ads by placing them within the themes code.

    Elad, I want to start a free wordpress powered blog hosting with revenue sharing. I don’t want to code the themes directly. I want to give more freedom to the blog users, to select the placement & size of the Ad-Unit. Is there any way to increase the number of widgets?

    I uploaded it fine and set everything up, but when I try to change the default 120 width and 240 height or anything for that matter in the backend, I get

    “Fatal error: Call to undefined function: array_key_s() in /home/sportsbl/public_html/wp-content/mu-plugins/adsense-share-mu.php on line 68″

    If i leave it alone and use the default settings it seems to work fine, but I’d really like to at least add a channel in adsense

    hopefully i’ll use this.
    so you 20% set admin pubId, and the rest client(publisher) ID.

    as You said “I will not deal with the ad code except for the google_ad_client which is the Adsense publisher code.”

    this will be OK until google not change the other parts of a code.

    when channels, or now, slots not from ad_client are.
    what then?

    i think you shoud exchange complete code.

    and client(publisher) can tell whitch format he used.
    you have all formats with you code in place. so use rigth this format.

    thanks

    This plugin is against Adsense TOS:

    Can I alter the AdSense ad code?
    Our program policies do not permit the modification of the AdSense code. Your publisher account offers a number of options when generating the ad code, that we hope will allow you to create an ad layout that fits in with your site.

    Please paste the AdSense ad code into your webpages without making any modifications.

    Again, please note that modification of the AdSense code is a violation of the AdSense program policies. For example, publishers may not:

    Alter the height or width of an ad unit from the standard options
    Implement the AdSense ad code in a “floating box script” or in a way that otherwise covers content
    Use any means to force the display of more than three AdSense ad units on a page
    Manipulate the ad targeting using hidden keywords, IFRAMEs, or any other method
    Distribute ads in emails or software

    Plugin activated OK, was able to take Adsense code, and appears in the list of widgets.

    However, when you try to drag this widget to the sidebar the whole screen goes blank.

    I’ve tried it a few times and it happens every time but only to this particular widget. In between I dragged other widgets to sidebar with no problem, so the problem is definately this plugin.

    I deleted this Plugin because it doesn’t appear to work with the most recent setup.

    I then uploaded the Plugin from http://blog.hoofoo.net/index.php/category/wordpress-mu/ This is the same Plugin with changes to make it work with the latest setup, and it appears to be working fine on my setup of WPMU 2.9.2 and BuddyPress.
