虽然我一直用的是Wordpress自带的TwentyFourteen主题，但是其实还是自己改动了很多地方的。以致于时间一长就有些功能是在哪改的都忘了，比如之前直接输入https://youthlin.com/links的话会跳转到首页，得从站内点击才能打开这个链接页面。之前也一直没在意，上周觉得这样不好，因为我发布一个页面https://youthlin.com/?page_id=1183直接打开会跳到首页而不是打开页面。额(-｡-;)于是打算重整一下主题了。
计划一是自己写个主题，然而技术还不到家现在也没时间。
计划二就是改用子主题啦。
通过子主题可以把网上流传的各种(通过在
functions.php添加代码的)特性集成到博客中，而又不需要修改原主题，即使原主题升级了也不会被覆盖。
子主题很早就知道啦，可以看看WP大学的文章简单了解下：使用WORDPRESS的子主题功能修改你的WORDPRESS主题
首先是style.css, 按照模板写就行了，不过不推荐用@import方式导入原主题样式，建议把原来的样式压缩一下直接粘贴过来，用在线网站就能压缩CSS百度一下很多的。这样能稍微提高下打开网站的速度。然后自己要自定义的样式写在他后面就行。
下面说说functions.php的内容，Wordpress大学那片文章说子主题的functions.php比原主题先载入(而style.css是替换原主题的样式表)。这个不是很要紧，反正他不会覆盖就行了，也就是不用把原来的拷贝过来。
于是，很多自定义的功能就可以都加在子主题的这个functions.php里。比如：
- 替换Google字体
- 评论回复通知(网上流传的使用comments-ajax.php的版本)
- 登录页面添加验证码、添加参数
- 替换默认的Emoji地址
- 添加自定义表情支持
- 添加自定义小工具，如带头像的近期评论、随机文章
- 在header, footer添加自定义代码，如添加返回顶部、滚到底部、定位到评论的功能；评论分页ajax载入的功能。
以上部分内容可参见：
- 不修改源文件优化’近期评论’小工具(带头像哦)
- WordPress分页评论AJAX载入
- 更新了下页面底部（添加返回顶部固定浮动条）
提醒：需要注意的是路径问题。(这个示例的子主题文件夹名称是2014)
下面是functions.php的内容：
<?php

//统计浏览量，配合WP-PostViews插件

修改步骤一:
把(_x('%1$s on %2$s', 'widgets')里面的这个单词“on”改成冒号“：”。
修改步骤二：
把get_the_title($comment->comment_post_ID)改为mb_strimwidth(strip_tags($comment->comment_content),0,50, 。。。》)。 这里的数字“50”是用来限制评论显示的字数，可以自行修改，至于后边那个小尾巴"。。。》"则是用来在实际评论字数少于允许显示的字数时补充空白处的，也可以依自己喜欢的格式修改之。(_注:。。。》要用单引号括起来)
以上修改完成后，最新评论的格式就变为：“读者ID”+"："+“实际评论内容”。
2）让最新评论不显示作者自己的评论
修改对象依然是上面提到的default-widgets.php文件。
搜索到以下代码片段：
$comments = get_comments( apply_filters( 'widget_comments_args', array( 'number' => $number, 'status' => 'approve', 'post_status' => 'publish' ) ) );
修改为以下格式：
$comments = get_comments( apply_filters( 'widget_comments_args', array( 'number' => $number, 'status' => 'approve', 'post_status' => 'publish', 'type' => 'comment', 'user_id' => 0 ) ) );
解释一下：'user_id' => 0效果为不显示站长自己的回复，'type' => 'comment'效果为只显示评论类留言，即，不显示pingback和trackback类留言。

其中：
- 替换字体，原主题是使用
twentyfourteen_font_url函数加载字体的，子主题不能重新定义这个函数，因此新顶一个函数，然后使用过滤器add_filter('twentyfourteen_font_url','my_font_url');替换原函数。 - 评论通知需要
comments-ajax.php,comments-ajax.js配合使用，还需要修改一下父主题的comments.php模板，添加自定义表情也要改一下评论模板。

其他文件也可以自定义，都会覆盖父主题，所以一般都是把父主题的模板拷贝过来修改。比如上面的评论模板，还有我还改了个404模板。 用意是：贡献404，让迷失宝贝回家

“以子主题方式自定义WordPress”上的6条回复
我也是用的Twenty fourteen 改的子主题。![[/呲牙]](https://youthlin.com/wp-content/themes/twentytwenty-child/images/smilies/呲牙.gif)
WP功能已经多到让我蛋疼，完全没心情自己改了……
子主题的方法不错，不惧主题升级。
不知道为什么评论到回收站里了……
感觉网站打开比以前慢了
