修正WordPress4.2自定义表情路径变成s.w.org/…

前些日子发现评论内的自定义表情路径都跳转到s.w.org，原来wordpress从4.2开始添加了emoji表情，而由于大陆的网络环境（你们懂得），导致网站打开变慢，在这里附上解决方案。

这段代码是从网上找来的，由于这篇文章闲置了几个星期，所以暂时无法找到出处。

//4.2表情修正
function disable_emoji9s_tinymce( $plugins ) {
	if ( is_array( $plugins ) ) {
		return array_diff( $plugins, array( 'wpemoji' ) );
	} else {
		return array();
	}
}

function remove_emoji9s() {
	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_emoji9s_tinymce' );
}

add_action( 'init', 'remove_emoji9s' );

function custom_smilie9s_src( $old, $img ) {
    return get_stylesheet_directory_uri().'/images/smilies/'.$img;
}

function init_smilie9s(){
	global $wpsmiliestrans;
	//默认表情文本与表情图片的对应关系(可自定义修改)
