WordPress技巧：如何禁用emoji表情

WordPress 4.2 之后改为了 emoji 表情，但国内环境并不支持 emoji 表情的访问。我们只能禁掉 emoji 表情，恢复之前的图片表情。

禁掉 Emoji 表情

//禁用 Emoji 功能
remove_action( 'admin_print_scripts', 'print_emoji_detection_script' );
remove_action( 'admin_print_styles', 'print_emoji_styles' );
remove_action( 'wp_head', 'print_emoji_detection_script', 7 );
remove_action( 'wp_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' );

恢复图片表情

//Reset smilies
function smilies_reset() {
    global $wpsmiliestrans, $wp_smiliessearch;
    if ( !get_option( 'use_smilies' ) )
    return;
    $wpsmiliestrans = array(
