WordPress 非插件实现评论表情功能的方法霓虹建站 > 后花园 > WordPress

实现WordPress博客评论表情的方法有两种,一种是直接使用博客插件实现,另一种就是用代码调用,使用插件实现的方法博客吧后面再讲,这一篇博客吧介绍如何使用代码调用实现WordPress博客评论表情功能的方法。

实现原理:

在WordPress博客的include/images/目录下有一个表情目录smilies,实现WordPress博客评论表情中的表情主要是调用该目录下的表情图片

实现方法步骤:

1、把下面代码用UTF8编码保存并命名为smiley.php,或者直接下载smiley.php文件(如果担心有病毒就复制下面的代码保存成smiley.php文件吧)

<script type="text/javascript">

    function grin(tag) {
      var myField;
      tag = ' ' + tag + ' ';
        if (document.getElementById('comment') && document.getElementById('comment').type == 'textarea') {
        myField = document.getElementById('comment');

        var startPos = myField.selectionStart;
        var endPos = myField.selectionEnd;
        var cursorPos = startPos;
        myField.value = myField.value.substring(0, startPos)

        myField.focus();
        myField.selectionStart = cursorPos;
        myField.selectionEnd = cursorPos;

        myField.focus();

2、把smiley.php上传到当前主题根目录下

3、登陆博客,点击外观选项卡下的编辑选项进入主题编辑页面

4、选择comments.php文件,在文件代码中找到<textarea,在其前面添加代码

<?php include(TEMPLATEPATH . '/smiley.php'); ?>

或者在代码中找到</textarea>,在其后面添加代码

5、保存更新文件,添加完毕,效果看下图:

提示:如果想更换表情图片,就把smilies目录下的表情图片替换或者在smilies目录下增加图片,然后在smiley.php文件中添加调用代码即可。
