WordPress 修复仪表盘评论头像错位 禁用 Emoji 表情

WordPress 4.2 一改之前的图片表情，改为使用 Emoji 表情 ，而且是直接远程调用api，可惜的是，这个api服务在国内是无法正常访问的，这就导致了网站加载缓慢，之前的表情无法显示等问题。好吧，下面就来禁用这个 Emoji 表情，恢复之前的图片表情。

禁用 Emoji 表情

在主题的 functions.php 添加代码的代码即可：

/**
Disable the emoji's
WordPress 修复仪表盘评论头像错位 禁用 Emoji 表情

 */
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' ) );

恢复之前的图片表情

在主题的 functions.php 添加代码的代码即可：

/**
 * WordPress 4.2 修复图片表情
 * https://www.waizhuti.com/650.html
 */
function smilies_reset() {
    global $wpsmiliestrans, $wp_smiliessearch;
 
    // don't bother setting up smilies if they are disabled
    if ( !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',

        ':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();

解决仪表盘头像错位

WordPress 4.2 开始，仪表盘的“活动”小工具的头像就出现撑破现象，如下图：

将下面的代码添加到主题的 functions.php ：

/**
 * WordPress 4.2 修复仪表盘头像错位
 * https://www.waizhuti.com/650.html
 */
function fixed_activity_widget_avatar_style(){
  echo '<style type="text/css">
            #activity-widget #the-comment-list .avatar {
            position: absolute;
            top: 13px;
            width: 50px;
            height: 50px;
          }
          </style>';
}
add_action('admin_head', 'fixed_activity_widget_avatar_style' );

好了 教程结束！
