hs4wp

http://www.neoease.com/highslide4wp/ MG的这个插件很不赖，对于俺来说，如果显示图的话，我宁可用lightbox，萝卜青菜各有所爱。

但是表情用这个来show很炫滴… 似乎有些人出现了这个问题吧。

很不幸的是，我也遇到了这个问题…看似是数据类型不正确…去PK这个变量吧 于是将修改为但是发现还是有问题… 翻看wp的表情转换函数，

看到下面的句子了吧，如果没有打开表情自动转换的话…那么你的数组=Null…自然报错如果你还是不想打开表情自动转换的话，那么将添加到出错的函数内…使用的是没问题了，但是呢，评论表情是不会转换的。 如果你使用MG的这个主题的话，那么这样修改一下吧[comments.php文件]如果你只想使用这个炫炫的表情展开特效，可以这么做 替换highslide4wp.php内的函数
