Explanation

If you're looking to speed up your WordPress site by disabling emojis, here's a simple way to do it without using a plugin.

What This Code Does:

Stops Emoji Scripts: It removes the emoji scripts from loading on your site's front-end, admin area, RSS feeds, and emails. This means your site won't load unnecessary emoji-related files, which can help improve performance.
Disables TinyMCE Emoji Plugin: It also prevents the TinyMCE editor (the tool you use to write posts) from loading its emoji plugin, keeping things streamlined.

How It Works:

The code uses remove_action to stop WordPress from adding emoji scripts and styles to different parts of your site.
It also uses remove_filter to ensure emojis aren't added to RSS feeds or emails.
Finally, it modifies the TinyMCE editor settings to exclude the emoji plugin using add_filter.

By adding this code to your theme's functions.php file, you can effectively turn off emojis across your WordPress site, helping it load faster and reducing unnecessary bloat.

Code

// Function to disable emojis in WordPress
function wp_dudecom_disable_emojis() {
    // Remove the emoji script from the front-end
    remove_action('wp_head', 'print_emoji_detection_script', 7);
    remove_action('wp_print_styles', 'print_emoji_styles');
    
    // Remove the emoji script from the admin area
    remove_action('admin_print_scripts', 'print_emoji_detection_script');
    remove_action('admin_print_styles', 'print_emoji_styles');
    
    // Remove the emoji script from the RSS feeds
    remove_filter('the_content_feed', 'wp_staticize_emoji');
    remove_filter('comment_text_rss', 'wp_staticize_emoji');
    
    // Remove the emoji script from the emails
    remove_filter('wp_mail', 'wp_staticize_emoji_for_email');
    
    // Remove the TinyMCE emoji plugin
    add_filter('tiny_mce_plugins', 'wp_dudecom_disable_emojis_tinymce');
}

// Function to remove the TinyMCE emoji plugin
function wp_dudecom_disable_emojis_tinymce($plugins) {
    if (is_array($plugins)) {
        return array_diff($plugins, array('wpemoji'));
    }
    return array();
}

// Hook the function into WordPress
add_action('init', 'wp_dudecom_disable_emojis');

Instructions

File Location: Add the code to your theme's functions.php file or a custom plugin file.

Prerequisites: No additional plugins or settings are required.
