WordPress 解决后台速度极慢 屏蔽国外字体Google Fonts

2014-6-2更新：近来谷歌的字体服务异常不稳定，WordPress也因为这个后台加载至少要20s。特殊时期特殊处理，刚开始以为是服务器问题，仔细分析，是载入字体的时候延时，于是就用开发者工具查看了一下，原来字体使用的是Google Fonts Open Sans，在国内访问不稳定所以会延时，解决方法很简单：

直接添加到主题的functions.php中即可禁用后台Open Sans：

//禁用Open Sans
class Disable_Google_Fonts {
        public function __construct() {
                add_filter( 'gettext_with_context', array( $this, 'disable_open_sans'             ), 888, 4 );
        }
        public function disable_open_sans( $translations, $text, $context, $domain ) {
                if ( 'Open Sans font: on or off' == $context && 'on' == $text ) {
                        $translations = 'off';
                }
                return $translations;
        }
}
$disable_google_fonts = new Disable_Google_Fonts;

附官方Twenty系列主题去除代码：

class Disable_Google_Fonts {
        public function __construct() {
                add_filter( 'gettext_with_context', array( $this, 'disable_open_sans'             ), 888, 4 );
                add_action( 'after_setup_theme',    array( $this, 'register_theme_fonts_disabler' ), 1      );
        }
        public function disable_open_sans( $translations, $text, $context, $domain ) {
                if ( 'Open Sans font: on or off' == $context && 'on' == $text ) {
                        $translations = 'off';
                }
                return $translations;
        }
        public function disable_lato( $translations, $text, $context, $domain ) {
                if ( 'Lato font: on or off' == $context && 'on' == $text ) {
                        $translations = 'off';
                }
                return $translations;
        }
        public function disable_source_sans_pro( $translations, $text, $context, $domain ) {
                if ( 'Source Sans Pro font: on or off' == $context && 'on' == $text ) {
                        $translations = 'off';
                }
                return $translations;
        }
        public function disable_bitter( $translations, $text, $context, $domain ) {
                if ( 'Bitter font: on or off' == $context && 'on' == $text ) {
                        $translations = 'off';
                }
                return $translations;
        }
        public function register_theme_fonts_disabler() {
                $template = get_template();
                switch ( $template ) {
                        case 'twentyfourteen' :
                                add_filter( 'gettext_with_context', array( $this, 'disable_lato'            ), 888, 4 );
                                break;
                        case 'twentythirteen' :
                                add_filter( 'gettext_with_context', array( $this, 'disable_source_sans_pro' ), 888, 4 );
                                add_filter( 'gettext_with_context', array( $this, 'disable_bitter'          ), 888, 4 );
                                break;
                }
        }
}
$disable_google_fonts = new Disable_Google_Fonts;
