实现效果

正文开始

此项目基于龙笑天下博客，教程大部分源自龙笑天下

function lxtx_secret_content($atts, $content=null){
extract(shortcode_atts(array('key'=>null,'keyword'=>null), $atts));
if(isset($_POST['secret_key']) && $_POST['secret_key']==$key){
return '<div class="secret-password">'.$content.'</div>';
} else {
return
'<link rel="stylesheet" href="https://cdn.bootcss.com/font-awesome/4.7.0/css/font-awesome.css">
<div class="gzhhide">
<div ><img class="gzhcode" align="right" src="https://tupian.qwbk.net/demo/2022/03/1300a435e364862_1_avatar.gif" width="130" height="130" alt="科技小新"></div>
<div class="gzhtitle">抱歉！隐藏内容，请输入密码后可见！<i class="fa fa-lock"></i><span></span></div>

add_shortcode('gzh2v', 'lxtx_secret_content');

2 前端 CSS 样式

2020年1月5日更新之前有很多小伙伴反映css链入错误。已经修正，直接把下边的css丢到主题的style.css即可。本次还修复了 小锁图标倾斜的问题

3 集成短代码

// 后台文本编辑框中添加公众号隐藏简码按钮
function lxtx_wpsites_add_gzh_quicktags() {
if (wp_script_is('quicktags')){
?>
<script type="text/javascript">
QTags.addButton( 'gzh2v', ' 公众号隐藏', '[把我删掉gzh2v keyword="关键字" key="验证码"]隐藏内容[/gzh2v把我删掉]', "" );
</script>
<?php
}
}
add_action( 'admin_print_footer_scripts', 'lxtx_wpsites_add_gzh_quicktags' );
