问题描述：

升级 3.6.1 后，PC端编辑器无法显示，具体表现如下：

• 移动端无碍（因为移动端使用的插件是wc_mobile_editor）
• PC端无法显示，不论后台卸载后重装，或者设置什么配置，都无效。

导致原因：

代码的Bug，导致JS脚本无法正常切换和加载。

代码的具体位置是：\plugins\wc_editor\view\init.tpl.htm

<?php if($this->type=='markdown' || $this->type=='all') {?>

这段代码中，$this->type 是无法取到值的。结果就是无法进行编辑器类型匹配，所以对应的js脚本就无法加载。

解决方案

总体思路就是，获取正确的编辑类型值：$this->config['type']['value'] 然后进行类型判断。

最简单的 的方法，大家可以把我下面的代码，完全覆盖\plugins\wc_editor\view\init.tpl.htm文件

<?php $editor_type = $this->config['type']['value'] ?>
<link rel="stylesheet" type="text/css" href="<?PHP echo $this->path;?>/style.css">
<?php if($editor_type=='all') {?>
<ul class="aw-editor-checked">
    <li class="active">Markdown</li>
    <li>富文本</li>
</ul>
<?php } ?>

<div class="aw-editor">

        <textarea style="display: none;" id="wangcontent" rows="15" name="<?php echo $this->param['name']; ?>"><?php echo $this->param['value']; ?></textarea>

覆盖完后，插件wc_editor就正常工作了
