WordPress 调用百度翻译进行文章别名转换

对于 WordPress 的固定链接来说,懒人就直接用 postid,喜欢来点个性的就会用 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,黑鸟今天看到了一个很棒的解决方案。

《WordPress 调用百度翻译进行文章别名转换》

其实 WordPress 有各种针对文章别名的翻译插件,也有相关的代码实现的教程,一般是通过 WordPress 动作钩子在 WordPress 发布或者更新文章的时候才能执行翻译,不能在文章保存文章时候就先翻译出来,造成发布后多次修改固定链接,不利于SEO。

所以以下提供的方法就是利用 js 方式操作,配合百度翻译的API,当填写好文章的标题,保存后单击文章别名后的翻译即可,如果翻译不满意还可以手动二次修改,保存发布一气呵成,堪称完美。以下代码放到主题 functions.php 文件内:

// 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='".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>";
}

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。

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。A
