I noticed when doing a view source of a recent CP project, I saw this:
<link rel=‘dns-prefetch’ href=‘//twemoji.classicpress.net/’ />
There are no other references to this domain in the page, which begs two questions:
I think it’s there to be able to call in emojis quickly. But if you dont use that, you can probably remove it. Though how to do that I am not completely clear on. Maybe @james can help and/or shed more light on this.
You can remove it using filters:
add_filter ( 'emoji_svg_url' , 'zigpress_kill_emoji' );
function zigpress_kill_emoji( $string ){
return "";
};
Seems to work but needs to be tested better than I did.
Simone.
OK, I’ve found that filter in wp-includes and I can see how it works.
But I also have the following in my theme:
remove_action(‘wp_head’, ‘print_emoji_detection_script’, 7 );
remove_action(‘admin_print_scripts’, ‘print_emoji_detection_script’ );
remove_action(‘wp_print_styles’, ‘print_emoji_styles’ );
remove_action(‘admin_print_styles’, ‘print_emoji_styles’ );
which is intended to remove all emoji processing - I thought that would prevent the prefetch being output?
Try this:
add_filter('emoji_svg_url' , '__return_false');
It should work without setting a priority.
Yes, I can confirm that works.
But what’s bugging me is that I thought emojis were being removed from CP altogether? Or is that something for v2?
Good to hear. I had this same question back in my WP days … it does seem to take an awful lot of filters to fully remove emojis.
The idea to remove emojis received a lot of interest and it is planned for v2; see the note at the top of the petition. In the meantime, we’ll have to rely on the filters.
OK, thanks for clarifying, I’ve upvoted the petition.
And I’ve published a brief post to help people get the filters right if they’re interested.
A minor but important point: let’s be a little more accurate with our language please - we’re not removing emojiis, we’re moving them to a core plugin.
I’m sure everyone here knows what they mean, but someone new to CP won’t.
