Wordpress表情符号禁用代码不起作用

Question

我尝试使用以下代码禁用wordpress中的表情符号代码。它工作了一段时间，但在最新升级后，我再次看到那些该死的表情符号。这是我在子主题函数中使用的代码。

/**
 * Disable the emoji's
 */
function disable_emojis() {
 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' ); 
 remove_filter( 'the_content_feed', 'wp_staticize_emoji' );
 remove_filter( 'comment_text_rss', 'wp_staticize_emoji' ); 
 remove_filter( 'wp_mail', 'wp_staticize_emoji_for_email' );
 add_filter( 'tiny_mce_plugins', 'disable_emojis_tinymce' );
 add_filter( 'wp_resource_hints', 'disable_emojis_remove_dns_prefetch', 10, 2 );
}
add_action( 'init', 'disable_emojis' );

/**
 * Filter function used to remove the tinymce emoji plugin.
 * 
 * @param array $plugins 
 * @return array Difference betwen the two arrays
 */
function disable_emojis_tinymce( $plugins ) {
 if ( is_array( $plugins ) ) {
 return array_diff( $plugins, array( 'wpemoji' ) );
 } else {
 return array();
 }
}

/**
 * Remove emoji CDN hostname from DNS prefetching hints.
 *
 * @param array $urls URLs to print for resource hints.
 * @param string $relation_type The relation type the URLs are printed for.
 * @return array Difference betwen the two arrays.
 */
function disable_emojis_remove_dns_prefetch( $urls, $relation_type ) {
 if ( 'dns-prefetch' == $relation_type ) {
 /** This filter is documented in wp-includes/formatting.php */
 $emoji_svg_url = apply_filters( 'emoji_svg_url', 'https://s.w.org/images/core/emoji/2/svg/' );

$urls = array_diff( $urls, array( $emoji_svg_url ) );
 }

return $urls;
}

但无论我尝试什么，我仍然看到在pingdom工具中调用emojis cdn和css。请帮忙！我的网站是bewitcheryinc.com

有一个插件，Disable Emojis。

或者，您可以使用Classic Smilies将早期版本的WordPress中的原始版本替换为表情符号。

您还可以通过在过滤器emoji_svg_url上返回false来删除DNS预取：

add_filter( 'emoji_svg_url', '__return_false' );

希望这可以帮助你:)

看起来代码改为：

/**
 * Remove emoji CDN hostname from DNS prefetching hints.
 *
 * @param  array  $urls          URLs to print for resource hints.
 * @param  string $relation_type The relation type the URLs are printed for.
 * @return array                 Difference betwen the two arrays.
 */
function disable_emojis_remove_dns_prefetch( $urls, $relation_type ) {

    if ( 'dns-prefetch' === $relation_type ) {

        // Strip out any URLs referencing the WordPress.org emoji location.
        $emoji_svg_url_bit = 'https://s.w.org/images/core/emoji/';
        foreach ( $urls as $key => $url ) {
            if ( strpos( $url, $emoji_svg_url_bit ) !== false ) {
                unset( $urls[ $key ] );
            }
        }
    }

    return $urls;
}
