What's adblock plus? A browser extension? In order to be able to switch modules etc you would need to have some way of detecting this, from the web server end.

Do you know if there's any way of doing this? Does adblock plus perhaps announce itself in the User Agent string or something like that?

If it remains invisible then it's going to be very hard to detect, in order to provide alternative content.

Hi,

I've had a look at some code suggested on the net for detecting adblock plus. It's along the lines of creating a javascript file that Adblock Plus would block. In that file there is a snippet of JS that hides the alternative content on screen.

I have deliberately avoided putting code into MetaMod that displays things to the end user apart from modules themselves, e.g. by adding JS code etc. I'm still not very keen to do it at this stage for architectural reasons, though I can see why you would want the ability to do this.

Anyway, the Joomla extension you linked to almost certainly does this.

What I'd suggest trying is this. You'll need to do some work with it, but I think you could get it to work:

1 - create a new module position perhaps just above or below the position that has your ad in it. This will contain your alternative content modules.
2- around the module position place a div with class="ffix"
3 - assign your "alternative content" module(s) to the new module position
4 - use a MetaMod to control whether/when the new modules appear or not
5 - create a file and save it in the root web folder of your joomla install. It should be accessible at the URL "http://www.mydomain.com/advertisement.js". Give it the following content:

document.write('<style type="text/css">.ffix {display:none!important;}</style>');

6 - add this to the head of your template:

<script src='http://www.mydomain.com/advertisement.js' type='text/javascript'/>

7 - that's it.

I haven't tested it but I hope this will at least get you started. Please write back to let us know how you get on!

Cheers,
