大家知道我们使用的DEDECMS默认的评论页，会员在添加评论的时候只可以选择一个表情。给我的感觉实在是不灵活，有些人发布评论的时候，可能需要表情和文字都结合，这样发出来的东西才有声有色的嘛。能不能修改下，实现多个表情呢？经过一番研究，还真的实现呢！
大家只需要两步就可以了。
第一步修改  feedback_ajax.php   文件。该文件在 根目录下的 plus / 文件夹下。打开该文件以后，查找以下代码：if($dopost=='getlist')
在该代码的上面插入以下代码： 

function convertem($message){   
$a = array('[em01]','[em02]','[em03]','[em04]','[em05]','[em06]','[em07]','[em08]','[em09]','[em10]','[em11]','[em12]','[em13]','[em14]','[em15]','[em16]','[em17]','[em18]','[em19]','[em20]','[em21]','[em22]','[em23]','[em24]');  
$b = array('<img src="../../../images/mood/ico-mood-1.gif" />','<img src="../../../images/mood/ico-mood-2.gif" />','<img src="../../../images/mood/ico-mood-3.gif" />','<img src="../../../images/mood/ico-mood-4.gif" />','<img src="../../../images/mood/ico-mood-5.gif" />','<img src="../../../images/mood/ico-mood-6.gif" />','<img src="../../../images/mood/ico-mood-7.gif" />','<img src="../../../images/mood/ico-mood-8.gif" />','<img src="../../../images/mood/ico-mood-9.gif" />','<img src="../../../images/mood/ico-mood-10.gif" />','<img src="../../../images/mood/ico-mood-11.gif" />','<img src="../../../images/mood/ico-mood-12.gif" />','<img src="../../../images/mood/ico-mood-13.gif" />','<img src="../../../images/mood/ico-mood-14.gif" />','<img src="../../../images/mood/ico-mood-15.gif" />','<img src="../../../images/mood/ico-mood-16.gif" />','<img src="../../../images/mood/ico-mood-17.gif" />','<img src="../../../images/mood/ico-mood-18.gif" />','<img src="../../../images/mood/ico-mood-19.gif" />','<img src="../../../images/mood/ico-mood-20.gif" />','<img src="../../../images/mood/ico-mood-21.gif" />','<img src="../../../images/mood/ico-mood-22.gif" />','<img src="../../../images/mood/ico-mood-23.gif" />','<img src="../../../images/mood/ico-mood-24.gif" />');  
$message = str_replace($a,$b,$message);  
return $message;   
} 

这样第一步就算做完了。
接下来第二步我们再打开ajaxfeedback.htm 这个文件，该文件在你具体的模板目录下，系统默认的模板目录为  根目录下templets /default/ajaxfeedback.htm
打开该文件，找到以下代码<div class="dcmp-mood">，在它的下面有Ul  和Li  ， Li有12行。把这12行的Li 全部替换，替换的代码为

<img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-1.gif" onclick="javascript:document.getElementById('msg').value+='[em01]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-2.gif" onclick="javascript:document.getElementById('msg').value+='[em02]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-3.gif" onclick="javascript:document.getElementById('msg').value+='[em03]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-4.gif" onclick="javascript:document.getElementById('msg').value+='[em04]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-5.gif" onclick="javascript:document.getElementById('msg').value+='[em05]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-6.gif" onclick="javascript:document.getElementById('msg').value+='[em06]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-7.gif" onclick="javascript:document.getElementById('msg').value+='[em07]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-8.gif" onclick="javascript:document.getElementById('msg').value+='[em08]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-9.gif" onclick="javascript:document.getElementById('msg').value+='[em09]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-10.gif" onclick="javascript:document.getElementById('msg').value+='[em10]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-11.gif" onclick="javascript:document.getElementById('msg').value+='[em11]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-12.gif" onclick="javascript:document.getElementById('msg').value+='[em12]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-13.gif" onclick="javascript:document.getElementById('msg').value+='[em13]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-14.gif" onclick="javascript:document.getElementById('msg').value+='[em14]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-15.gif" onclick="javascript:document.getElementById('msg').value+='[em15]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-16.gif" onclick="javascript:document.getElementById('msg').value+='[em16]';" />  <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-17.gif" onclick="javascript:document.getElementById('msg').value+='[em17]';" /> <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-18.gif" onclick="javascript:document.getElementById('msg').value+='[em18]';" />  <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-19.gif" onclick="javascript:document.getElementById('msg').value+='[em19]';" />   <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-20.gif" onclick="javascript:document.getElementById('msg').value+='[em20]';" />  <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-21.gif" onclick="javascript:document.getElementById('msg').value+='[em21]';" /> <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-22.gif" onclick="javascript:document.getElementById('msg').value+='[em22]';" />  <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-23.gif" onclick="javascript:document.getElementById('msg').value+='[em23]';" /> <img src="{dede:global.cfg_cmsurl/}/images/mood/ico-mood-24.gif" onclick="javascript:document.getElementById('msg').value+='[em24]';" />

好了，通过两步的修改，已经OK了，接下来测试吧，看看最后测试的效果。还是很不错的。需要说明的是，表情的目录是在根目录的images  这个大家需要注意一下，图片目录大家可以随便改。我是为了防止泄露模板目录，所以直接放在了根目录里的images。
最后来张效果图：
