wordpress 4.2版本后自定义表情路径

wordpress 4.2新增了emoji表情，导致之前自定义的表情无法显示。

add_filter('smilies_src','custom_smilies_src',1,10);
function custom_smilies_src ($img_src, $img, $siteurl){
 return get_bloginfo('template_url').'/static/img/smilies/'.$img;
}

function mbtheme_init_smilies(){
 global $wpsmiliestrans;
 $wpsmiliestrans = array(
