之前备份过WordPress撰写文章时添加emoji表情的修改记录，升级到4.2后，在达人的帮助下搞定了前后台一片空白的问题。结果，写文章时发现添加emoji表情的功能不可用了。4.2自动支持emoji表情，可能在某些情况下造成自定义表情失效，我们可以暂时禁用这货。把下面的代码放到functions.php里即可。/*** 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_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 ） {return array_diff（ $plugins, array（ 'wpemoji' ） ）；}但是这样在写文章时还是无法添加自定义表情图片，还要再把下面的代码放到functions.php里面。function smilies_reset（） {global $wpsmiliestrans, $wp_smiliessearch;// don't bother setting up smilies if they are disabledif （ !get_option（ 'use_smilies' ） ）return;$wpsmiliestrans = array（':mrgreen:' => 'icon_mrgreen.gif',':neutral:' => 'icon_neutral.gif',':twisted:' => 'icon_twisted.gif',':arrow:' => 'icon_arrow.gif',':shock:' => 'icon_eek.gif',':smile:' => 'icon_smile.gif',':???:' => 'icon_confused.gif',':cool:' => 'icon_cool.gif',':evil:' => 'icon_evil.gif',':grin:' => 'icon_biggrin.gif',':idea:' => 'icon_idea.gif',':oops:' => 'icon_redface.gif',':razz:' => 'icon_razz.gif',':roll:' => 'icon_rolleyes.gif',':wink:' => 'icon_wink.gif',':cry:' => 'icon_cry.gif',':eek:' => 'icon_surprised.gif',':lol:' => 'icon_lol.gif',':mad:' => 'icon_mad.gif',':sad:' => 'icon_sad.gif','8-）' => 'icon_cool.gif','8-O' => 'icon_eek.gif',':-（' => 'icon_sad.gif',':-）' => 'icon_smile.gif',':-?' => 'icon_confused.gif',':-D' => 'icon_biggrin.gif',':-P' => 'icon_razz.gif',':-o' => 'icon_surprised.gif',':-x' => 'icon_mad.gif',':-|' => 'icon_neutral.gif',';-）' => 'icon_wink.gif',// This one transformation breaks regular text with frequency.// '8）' => 'icon_cool.gif','8O' => 'icon_eek.gif',':（' => 'icon_sad.gif',':）' => 'icon_smile.gif',':?' => 'icon_confused.gif',':D' => 'icon_biggrin.gif',':P' => 'icon_razz.gif',':o' => 'icon_surprised.gif',':x' => 'icon_mad.gif',':|' => 'icon_neutral.gif',';）' => 'icon_wink.gif',':!:' => 'icon_exclaim.gif',':?:' => 'icon_question.gif',）；}smilies_reset（）；同往常一样，本文的主用功能是备份。各位不要有评论压力，想说点什么就说，不想说就点，你懂的。
