\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’key\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => null,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’reply\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’
), $atts));
// 管理员登录直接显示隐藏内容
if ( current_user_can(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’level_10\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’) ) {
return \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'<div class=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”hidden-content\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.do_shortcode( $content ).\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'</div>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;
}
// 输入正确验证码显示隐藏内容
if(isset($_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’weixin_key\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’]) && $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’weixin_key\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’]==$key){
return \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'<div class=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”hidden-content\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.do_shortcode( $content ).\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'</div>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;

}
}
add_shortcode(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’weixin\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’weixin_fans\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’);
修改其中的：你的微信公众号名称
将第11行和24行的$key和\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.$reply.\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ 分别改为固定密码和回复关键词，可以统一密码和关键词，方便批量替换。
提示：因代码中有中文，所以修改保存 functions.php 文件时，模版编码选择：UTF-8 无BOM（无签名），否则中文会显示乱码。
配套样式：
.hidden-content, .weixin-form {
padding: 0 0.5rem;
border: 1px dashed #ff4400;
}
.weixin-n {
color: #ff4400;
}
.weixin-form img {
width: 150px;
height: auto;
}
添加到主题样式文件中或者外观 → 自定义 → 额外CSS中
使用方法：
编辑文章时输入：
[weixin key=验证码 reply=回复的内容]隐藏的内容[/weixin]
分别输入自动回复的验证码和回复的内容
提示：
要注意验证码后面有一个半角的空格，否则输入验证码无效。
代码中无cookie功能，再次打开页面需要重新输入验证码。
管理员登录状态下直接显示隐藏的内容，不需要输入验证码。
短代码虽然目前已被区块编辑器所取代，不过短代码功能还是可以正常使用的。
