Exclude a div from amp pages,

@delphine Rather than create a function to remove a div for AMP URLs you could use the below conditional logic when inserting your ad. This would insert a trafitional traditional ad unit for your canonical URLs with an AMP ad unit replace your non AMP ad unit:

<?php if ( function_exists( 'is_amp_endpoint' ) && is_amp_endpoint() ) : ?>
    <amp-ad>...</amp-ad>
<?php else : ?>
    <div>...traditional ad unit code...</div>
<?php endif; ?>

There are also some plugins such as Advanced Ads that automatically convert traditional ad units into AMP ad units.

Let me know if that works for you.

Oh gosh, you are fast! Thanks!
I’m not sure if that would work (sorry, I’m not so great at this!).

The ads I use get inserted by a plugin (the old “Adsense Deluxe”) via short codes. I usually insert the ads manually in the body of the post.
This is the code I use:
<div class="alignright"><!--adsense#red_rect--></div>

I want them to show on the non amp pages (it’s a square at the top right of the content area) but get completely excluded from amp. So I thought making a class like .notonamp and doing something like this combined with something in functions.php would be the easiest.

<div class="alignright notonamp"><!--adsense#red_rect--></div>

If I’m thinking about this the wrong way, just let me know!

And thanks again for your help!

@delphine In that case adding a notonamp class should work. To ensure the div doesn’t display you can use a CSS solution such as the below, added to your style.css file or preferably a custom CSS plugin or theme option. This works for transitional mode.

html[amp] .notonamp{
display:none;
}

If you’re using reader mode you can apply the above within using the amp_post_template_css action.

The previous solution should also work. From the previous snippet replace the <div>...traditional ad unit code...</div> with the snippet/shortcode you currently use, <div class="alignright"><!--adsense#red_rect--></div>.

Woo hoo, thanks James! I will experiment and post my findings here (so it will help other people too).
All the best,
Lori
