给WordPress编辑器添加表情按钮，让文章萌萌哒！

给WordPress默认编辑器添加表情按钮，自由的给文章添加萌萌的表情，让文章萌起来23333

前言

传说有一种人叫表情控 ，不管发什么都想带几个表情 ，但是WordPress自带的编辑器确实木有表情按钮，这让身为表情控的博猪情何以堪，经过博猪百度一下，谷歌两下，找到了比较不错的解决方案了

函数代码

首先将以下代码加入functions.php文件

<span class="com"><span class="com">//输出<a href="http://www.goodziyuan.com/?tag=wordpress" title="查看更多关于WordPress的文章" target="_blank">WordPress</a><a href="http://www.goodziyuan.com/?tag=%e8%a1%a8%e6%83%85" title="查看更多关于表情的文章" target="_blank">表情</a></span></span>

自定义表情图片

将以下代码加入functions.php文件,可能很多主题已经做到了表情自定义了，这个可以忽略，具体看自己的主题吧

<span class="pln"><span class="pln">add_filter</span></span><span class="pun"><span class="pun">(</span></span><span class="str"><span class="str">'smilies_src'</span></span><span class="pun"><span class="pun">,</span></span><span class="str"><span class="str">'fa_smilies_src'</span></span><span class="pun"><span class="pun">,</span></span><span class="lit"><span class="lit">1</span></span><span class="pun"><span class="pun">,</span></span><span class="lit"><span class="lit">10</span></span><span class="pun"><span class="pun">);</span></span>
<span class="kwd"><span class="kwd">function</span></span><span class="pln"><span class="pln"> fa_smilies_src </span></span><span class="pun"><span class="pun">(</span></span><span class="pln"><span class="pln">$img_src</span></span><span class="pun"><span class="pun">,</span></span><span class="pln"><span class="pln"> $img</span></span><span class="pun"><span class="pun">,</span></span><span class="pln"><span class="pln"> $siteurl</span></span><span class="pun"><span class="pun">){</span></span><span class="pln"><span class="pln">

<span class="kwd"><span class="kwd">return</span></span><span class="pln"><span class="pln"> get_bloginfo</span></span><span class="pun"><span class="pun">(</span></span><span class="str"><span class="str">'template_directory'</span></span><span class="pun"><span class="pun">).</span></span><span class="str"><span class="str">'/img/smilies/'</span></span><span class="pun"><span class="pun">.</span></span><span class="pln"><span class="pln">$img</span></span><span class="pun"><span class="pun">.</span></span><span class="str"><span class="str">'png'</span></span><span class="pun"><span class="pun">;</span></span>
<span class="pun"><span class="pun">}</span></span>

效果图

后语

一篇文章如果纯粹都是文字的话看乏力，图文并茂才是王道，当然文章多几个萌萌的表情，会让文章变得生动不小，这篇文章的代码就可以在编辑器直接插入表情按钮，省的还需要自己插入表情代码。
