如何在DEDECMS中实现会员评论时添加多个表情功能？

在织梦DEDECMS系统中，默认情况下会员在评论时只能选择一个表情，这在一定程度上限制了评论的表达力和丰富性，为了提高用户体验，使评论更加生动有趣，可以通过简单的代码修改实现会员评论时添加多个表情的功能，以下是具体步骤：

第一步：修改feedback_ajax.php文件

1、定位文件：找到并打开位于根目录下plus文件夹中的feedback_ajax.php文件。

2、插入代码：在该文件中查找以下代码：

“`php

if($dopost==’getlist’)

“`

在这段代码的上面插入以下代码：

“`php

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/icomood1.gif" />’,'<img src="../../../images/mood/icomood2.gif" />’,'<img src="../../../images/mood/icomood3.gif" />’,'<img src="../../../images/mood/icomood4.gif" />’,'<img src="../../../images/mood/icomood5.gif" />’,'<img src="../../../images/mood/icomood6.gif" />’,'<img src="../../../images/mood/icomood7.gif" />’,'<img src="../../../images/mood/icomood8.gif" />’,'<img src="../../../images/mood/icomood9.gif" />’,'<img src="../../../images/mood/icomood10.gif" />’,'<img src="../../../images/mood/icomood11.gif" />’,'<img src="../../../images/mood/icomood12.gif" />’,'<img src="../../../images/mood/icomood13.gif" />’,'<img src="../../../images/mood/icomood14.gif" />’,'<img src="../../../images/mood/icomood15.gif" />’,'<img src="../../../images/mood/icomood16.gif" />’,'<img src="../../../images/mood/icomood17.gif" />’,'<img src="../../../images/mood/icomood18.gif" />’,'<img src="../../../images/mood/icomood19.gif" />’,'<img src="../../../images/mood/icomood20.gif" />’,'<img src="../../../images/mood/icomood21.gif" />’,'<img src="../../../images/mood/icomood22.gif" />’,'<img src="../../../images/mood/icomood23.gif" />’,'<img src="../../../images/mood/icomood24.gif" />’);

$message = str_replace($a,$b,$message);

return $message;

}

“`

这一步的作用是将文本中的表情标签替换为相应的图片标签，从而实现表情的显示。

第二步：修改ajaxfeedback.htm文件

1、定位文件：找到并打开位于模板目录（默认路径为templets/default/ajaxfeedback.htm）下的ajaxfeedback.htm文件。

2、替换代码：在该文件中找到以下代码段：

“`html

<div class="dcmpmood">

<!这里通常会有一组Li元素，每个Li包含一个表情 >

</div>

“`

将其中的<ul>和<li>元素替换为以下代码：

“`html

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood1.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em01]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood2.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em02]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood3.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em03]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood4.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em04]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood5.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em05]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood6.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em06]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood7.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em07]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood8.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em08]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood9.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em09]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood10.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em10]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood11.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em11]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood12.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em12]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood13.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em13]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood14.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em14]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood15.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em15]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood16.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em16]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood17.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em17]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood18.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em18]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood19.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em19]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood20.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em20]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood21.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em21]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood22.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em22]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood23.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em23]’;" />

<img src="{dede:global.cfg_cmsurl/}/images/mood/icomood24.gif" onclick="javascript：document.getElementById(‘msg’).value+='[em24]’;" />

这样，当用户点击这些表情图片时，就会在评论输入框中插入对应的表情标签，从而实现多表情功能。

通过以上两个步骤的修改，DEDECMS系统的评论功能就可以支持会员在评论时添加多个表情，使得评论内容更加丰富多彩、生动有趣，希望这篇文章能够帮助你顺利实现这一功能，如果有任何疑问或需要进一步的帮助，请随时联系我。
