WordPress 文章别名增加手动点击百度翻译
对于 WordPress 的固定链接来说，懒人喜欢直接用 postid，喜欢有意思一点的就会使用 postname，也就是通过 WordPress 文章别名来手动指定名称，而用传统的拼音或者简写的话有感觉不够有格调，而想要使用英文呢又没学好，那怎么办呢？子凡今天想到了一个自认为完美的解决方案。
其实 WordPress 有各种针对文章别名的翻译插件，也有相关的教程，不过实现的原理比较尴尬，是通过 WordPress 动作钩子在 WordPress 发布或者更新文章的时候才能执行翻译，不能在文章第一次就先翻译出来，并且如果第一次就推送了熊掌号，若翻译不准确还需要修改就会出现重复链接页面显得非常不尽人意了。
所以子凡提供的方法就是利用 js 方式开发，配合百度翻译的接口，当你填写好文章的标题，单击文章别名后的翻译即可，如果翻译不尽人意还可以手动二次修改，保存发布一气呵成，堪称完美。话不多说，直接上代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | // WordPress 文章别名增加手动点击百度翻译 add_action( 'admin_head-post.php', 'fanly_post_name_to_slug'); add_action( 'admin_head-post-new.php', 'fanly_post_name_to_slug'); function fanly_post_name_to_slug() { echo "<script type='text/javascript' src='https://zhangzifan.com/".get_stylesheet_directory_uri()."/js/md5.js'></script>"; echo "<script> jQuery(document).ready(function(){jQuery('#post_name').after('<span id=\"fanyi\" style=\"cursor:pointer;font-size:12px;font-weight:normal;padding-left:10px\">点击翻译</span>');}); jQuery(function($){ $(document).on('click', '#fanyi', function(){ var appid = 'APP ID';//修改为百度翻译 APP ID var key = '密钥';//修改为百度翻译密钥 var salt = (new Date).getTime(); var query = $('#title').val(); var sign = MD5(appid + query + salt +key); $.ajax({ url: 'https://fanyi-api.baidu.com/api/trans/vip/translate', type: 'get', dataType: 'jsonp', data: { q: query, appid: appid, salt: salt, from: 'zh', to: 'en', sign: sign }, success: function (data) { $('#post_name').val(data.trans_result[0]['dst']); console.log(data.trans_result[0]['dst']); } }); }); }); </script>"; } |
你以为就完成了？
由于 js 代码需要使用到 MD5，所以还需要载入一个 MD5 的 js 文件，然后放在当前主题目录中的 js 目录，并且以 md5.js 命名。
md5.js 文件内容：

你可以直接复制保存一下。或者直接去百度翻译接口的文档页面：http://api.fanyi.baidu.com/api/trans/product/apidoc 下载 JS 版，然后将里面的文件直接拷贝出来即可。
当然啦，你还需要在百度翻译开放平台：http://api.fanyi.baidu.com 申请 API 接口。使用方法就不赘述了，根据提示替换代码中的信息即可。
