前几天看到六维博客里看到了一篇博文WP博客评论区加入QQ表情，此功能很酷，想了想就移植到Micolog了，本人不懂php，只是解剖了他的源代码，稍加改造，并加上前几天研究如何给最新评论增加过滤功能的积累，就很简单的实现了。没写过插件，只是改造了代码也不知能不能叫插件！
１.首先下载 QQ表情包
上传到你的博客程序的image下，如果你有大菠萝相册，用GAE上传程序直接上传到大菠萝程序的static下。这样可以起到分流的作用！
２.在留言输入框附近 加如下代码：
<p>
<script type="text/javascript">/*<![CDATA[*/function grin(tag) {
if (typeof tinyMCE != 'undefined') {
grin_tinymcecomments(tag);
} else {
grin_plain(tag);
}
}
function grin_tinymcecomments(tag) {
tinyMCE.execCommand('mceInsertContent', false, ' ' + tag + ' ');
}
function grin_plain(tag) {
var myField;
var myCommentTextarea = "comment";
tag = ' ' + tag + ' ';
if (document.getElementById(myCommentTextarea) && document.getElementById(myCommentTextarea).type == 'textarea') {
myField = document.getElementById(myCommentTextarea);
} else {
return false;
}
if (document.selection) {
myField.focus();
sel = document.selection.createRange();
sel.text = tag;
myField.focus();
}
else if (myField.selectionStart || myField.selectionStart == '0') {
var startPos = myField.selectionStart;
var endPos = myField.selectionEnd;
var cursorPos = endPos;
myField.value = myField.value.substring(0, startPos)
+ tag
+ myField.value.substring(endPos, myField.value.length);
cursorPos += tag.length;
myField.focus();
myField.selectionStart = cursorPos;
myField.selectionEnd = cursorPos;
}
else {
myField.value += tag;
myField.focus();
}
}
function moreSmilies() {
document.getElementById('wp-smiley-more').style.display = 'inline';
document.getElementById('wp-smiley-toggle').innerHTML = '<a href="javascript:lessSmilies()">« less</a></span>';
}
function lessSmilies() {
document.getElementById('wp-smiley-more').style.display = 'none';
document.getElementById('wp-smiley-toggle').innerHTML = '<a href="javascript:moreSmilies()">more »</a>';
}/*]]>*/</script>

</p>
将http://hikeimg.appspot.com/static/images/icon/icon_exclaim.gif 的红色部分的路径替换成您上传ＱＱ表情的路径。过几天此路径可能失效！下面遇到同样的路径也要替换！
３.在blog.py的大概279行，增加红色部分。
if not (name and email and content):
if useajax:
self.write(simplejson.dumps((False,-101,_(‘Please input name, email and comment .’))))
else:
self.error(-101,_(‘Please input name, email and comment .’))
else:
comment=Comment(author=name,
content=content.replace(‘^~’,"<img src=http://hikeimg.appspot.com/static/images/icon/icon_").replace(‘~^’,’.gif />’),
email=email,
entry=Entry.get(key))
if url:
try:
comment.weburl=url
except:
comment.weburl=’http://’+url
４.为了使首页的最新评论不显示表情或图片，要做过滤。打开model.py，大概在464行。代码修改如下，复制红色部分即可。主要[：len]的位置有所改变！
@property
def shortcontent(self,len=24): #self.content[:len].replace
scontent=self.content.replace(‘<br />’,' ’).replace(‘<img src=http://hikeimg.appspot.com/static/images/icon/icon_’,'Icon(‘).replace(‘.gif />’,')’).replace(‘<’,'<’).replace(‘>’,'>’)[:len]
return scontent
OK，完成。自己发个表情试试
