emlog Pro| 给joe主题侧边栏友情链接头部增加一个ico图标

今天emlog Pro官网发布了2.3.0版本。给首页友情链接增加了一个ico图标功能和修复其他bug。

然后开始动手 给本站joe主题模板适配友情链接这个小组件功能。《至于为啥自己动手，之前有篇文章已经说明原因 不在废话》

相关链接可查看:https://blog.qqzzz.cn/dma/13.html

此功能目前存在一个bug，新添加的友情链接不会显示ico图标，添加友联之后 从新编辑把ico的链接输入进去 再次保存即可正常显示图标，已经反馈给emlog作者 下个版本会解决。

操作方法:

复制代码到joe主题模板目录，找到module.php 然后把下面的代码替换掉原来的友情链接即可。

ps:本代码只适合joe主题使用，其他主题自行适配。

//widget：链接
function widget_link($title) {
    global $CACHE;
    $link_cache = $CACHE->readCache('link');
    //if (!blog_tool_ishome()) return;#只在首页显示友链去掉双斜杠注释即可
    ?>
