WordPress用插件或修改代码实现回复可见、登录可见或输入密码可见

WordPress

相信很多同学在一些博客当中看到有些内容需要登录后、回复后或输入密码后才能看到，是不是觉得很有意思，可以相对的增加与访客的互动，特别是加密后输入密码可见可以上部分内容只针对特点人群开放。在此文章中蜗牛将为大家分享如何通过插件或代码来隐藏WordPress文章部分内容，让用户登录或输入密码后才能看见。

一、用插件方法实现

首先推荐一款小巧的插件：Login to view all，来实现使隐藏WordPress文章部分内容，让用户登录后可见。用插件的还出是简单便捷，只需下载插件并上传安装好启用即可。

1、百度网盘下载

Login to view all 插件 密码: 6xtk

2、WordPress官方下载：https://wordpress.org/plugins/login-to-view-all/

关于插件的使用及效果，就不做演示了，大家自己体验。

插件版优缺点：

使用插件版后，如果不想使用插件了，我们屏蔽插件后，原先文章内隐藏的内容会直接消失掉。这个缺点很致命，要用此插件就要决定长期使用下去。优点是与CDN加速兼容性较好，不会存在登录不显示内容的现象。

方二、修改代码方式实现

个人更倾向于使用代码，这里为大家介绍修改代码实现回复可见、登录可见或输入密码可见三种方式的修改操作。与插件版相比，代码版优缺点也是各半，大家自己斟酌选择。

代码版优缺点：

优点是与插件版相比，我们不想使用此功能时，取消相应代码，原先隐藏的内容会正常显示。缺点是与CDN加速兼容较差，会被缓存，如果你的站点开启了CDN加速，会出现登录也无法显示内容的情况。

1、简单版部分内容登录可见

在主题的functions.php文件添加以下代码：

<span class="hljs-comment">//部分内容登录可见</span>
add_shortcode(<span class="hljs-string">'hide'</span>,<span class="hljs-string">'loginvisible'</span>);
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">loginvisible</span><span class="hljs-params">($atts,$content=null)</span></span>{
    <span class="hljs-keyword">if</span>(is_user_logged_in() && !is_null($content) && !is_feed())
    <span class="hljs-keyword">return</span> $content;
    <span class="hljs-keyword">return</span> <span class="hljs-string">''</span>;
}
<span class="hljs-comment">//部分内容登录可见</span>
add_shortcode(<span class="hljs-string">'hide'</span>,<span class="hljs-string">'loginvisible'</span>);
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">loginvisible</span><span class="hljs-params">($atts,$content=null)</span></span>{
    <span class="hljs-keyword">if</span>(is_user_logged_in() && !is_null($content) && !is_feed())
    <span class="hljs-keyword">return</span> $content;
    <span class="hljs-keyword">return</span> <span class="hljs-string">''</span>;
}
//部分内容登录可见
add_shortcode('hide','loginvisible');
function loginvisible($atts,$content=null){
    if(is_user_logged_in() && !is_null($content) && !is_feed())
    return $content;
    return '';
}

如何实现？在编辑文章是使用短码包围要隐藏的内容，如下：

【hide】登陆才可以看到的内容【/hide】
【hide】登陆才可以看到的内容【/hide】
【hide】登陆才可以看到的内容【/hide】

把上面中文括号改为英文括号【】→[]
稍微会点代码的其实都挺简单的！

2、美化版部分内容登录可见

在主题function.php文件里加入以下代码。其中可用于直接将href=”#respond”后的“#respond”替换为自己站点的登录地址，以方便用户快速登录。

<span class="hljs-comment">//部分内容登录可见</span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">login_to_read</span><span class="hljs-params">($atts, $content=null)</span> </span>{
extract(shortcode_atts(<span class="hljs-keyword">array</span>(<span class="hljs-string">"notice"</span> => <span class="hljs-string">'
</span><span class="hljs-string">温馨提示：</span><span class="hljs-string">此处内容需要</span><a title="登录后可见" href="https://labishaxin.com/?golink=aHR0cHM6Ly93d3cuY2hlbmJvLmluZm8vZ28vSTNKbGMzQnZibVE9"><span class="hljs-string">登录</span></a><span class="hljs-string">后才能查看！
'</span>), $atts));
<span class="hljs-keyword">if</span> ( is_user_logged_in() && !is_null( $content ) && !is_feed() )
 <span class="hljs-keyword">return</span> $content;
 <span class="hljs-keyword">return</span> $notice;
}
add_shortcode(<span class="hljs-string">'vip'</span>, <span class="hljs-string">'login_to_read'</span>);
<span class="hljs-comment">//部分内容登录可见</span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">login_to_read</span><span class="hljs-params">($atts, $content=null)</span> </span>{
extract(shortcode_atts(<span class="hljs-keyword">array</span>(<span class="hljs-string">"notice"</span> => <span class="hljs-string">'
</span><span class="hljs-string">温馨提示：</span><span class="hljs-string">此处内容需要</span><a title="登录后可见" href="https://labishaxin.com/?golink=aHR0cHM6Ly93d3cuY2hlbmJvLmluZm8vZ28vSTNKbGMzQnZibVE9"><span class="hljs-string">登录</span></a><span class="hljs-string">后才能查看！
'</span>), $atts));
<span class="hljs-keyword">if</span> ( is_user_logged_in() && !is_null( $content ) && !is_feed() )
 <span class="hljs-keyword">return</span> $content;
 <span class="hljs-keyword">return</span> $notice;
}
add_shortcode(<span class="hljs-string">'vip'</span>, <span class="hljs-string">'login_to_read'</span>);
//部分内容登录可见
function login_to_read($atts, $content=null) {
extract(shortcode_atts(array("notice" => '
温馨提示：此处内容需要登录后才能查看！
'), $atts));
if ( is_user_logged_in() && !is_null( $content ) && !is_feed() )
 return $content;
 return $notice;
}
add_shortcode('vip', 'login_to_read');

如何实现？在编辑文章是使用短码包围要隐藏的内容，下面列举的是两种方式，我们任选一种即可。

【vip]我是被隐藏的内容，样式一（默认样式）【/vip】
【vip notice=<span class="hljs-string">"登录后才显示哟"</span>]我是被隐藏的内容，样式二（自定义回复信息）【/vip】
【vip]我是被隐藏的内容，样式一（默认样式）【/vip】
【vip notice=<span class="hljs-string">"登录后才显示哟"</span>]我是被隐藏的内容，样式二（自定义回复信息）【/vip】
【vip]我是被隐藏的内容，样式一（默认样式）【/vip】
【vip notice="登录后才显示哟"]我是被隐藏的内容，样式二（自定义回复信息）【/vip】

把上面中文括号改为英文括号【】→[]

本站使用内容登录可见示例

温馨提示：此处内容需要登录后才能查看！

3、输入密码显示

首先在主题functions.php文件中添加下面代码。

<span class="hljs-comment">//部分内容输入密码可见 </span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">e_secret</span><span class="hljs-params">($atts, $content=null)</span></span>{ extract(shortcode_atts(<span class="hljs-keyword">array</span>(<span class="hljs-string">'key'</span>=><span class="hljs-keyword">null</span>), $atts));
<span class="hljs-keyword">if</span>(<span class="hljs-keyword">isset</span>($_POST[<span class="hljs-string">'e_secret_key'</span>]) && $_POST[<span class="hljs-string">'e_secret_key'</span>]==$key){
 <span class="hljs-keyword">return</span> <span class="hljs-string">'<div class="e-secret">'</span>.$content.<span class="hljs-string">'</div>'</span>;
 }
<span class="hljs-keyword">else</span>{
 <span class="hljs-keyword">return</span> <span class="hljs-string">'<form class="e-secret" action="'</span>.get_permalink().<span class="hljs-string">'" method="post" name="e-secret"><label>输入密码查看加密内容：</label><input type="password" name="e_secret_key" class="euc-y-i" maxlength="50"><input type="submit" class="euc-y-s" value="确定"><div class="euc-clear"></div></form>'</span>;
 }
} 
add_shortcode(<span class="hljs-string">'secret'</span>,<span class="hljs-string">'e_secret'</span>);
<span class="hljs-comment">//部分内容输入密码可见 </span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">e_secret</span><span class="hljs-params">($atts, $content=null)</span></span>{ extract(shortcode_atts(<span class="hljs-keyword">array</span>(<span class="hljs-string">'key'</span>=><span class="hljs-keyword">null</span>), $atts));
<span class="hljs-keyword">if</span>(<span class="hljs-keyword">isset</span>($_POST[<span class="hljs-string">'e_secret_key'</span>]) && $_POST[<span class="hljs-string">'e_secret_key'</span>]==$key){
 <span class="hljs-keyword">return</span> <span class="hljs-string">'<div class="e-secret">'</span>.$content.<span class="hljs-string">'</div>'</span>;
 }
<span class="hljs-keyword">else</span>{
 <span class="hljs-keyword">return</span> <span class="hljs-string">'<form class="e-secret" action="'</span>.get_permalink().<span class="hljs-string">'" method="post" name="e-secret"><label>输入密码查看加密内容：</label><input type="password" name="e_secret_key" class="euc-y-i" maxlength="50"><input type="submit" class="euc-y-s" value="确定"><div class="euc-clear"></div></form>'</span>;
 }
} 
add_shortcode(<span class="hljs-string">'secret'</span>,<span class="hljs-string">'e_secret'</span>);
//部分内容输入密码可见 
function e_secret($atts, $content=null){ extract(shortcode_atts(array('key'=>null), $atts));
if(isset($_POST['e_secret_key']) && $_POST['e_secret_key']==$key){
 return '<div class="e-secret">'.$content.'</div>';
 }
else{
 return '<form class="e-secret" action="'.get_permalink().'" method="post" name="e-secret"><label>输入密码查看加密内容：</label><input type="password" name="e_secret_key" class="euc-y-i" maxlength="50"><input type="submit" class="euc-y-s" value="确定"><div class="euc-clear"></div></form>';
 }
} 
add_shortcode('secret','e_secret');

第二步到在自己主题main.css样式文件里添加下面代码。

<span class="hljs-comment">/*e-secret*/</span>
<span class="hljs-selector-class">.e-secret</span> {
 <span class="hljs-attribute">margin</span>: <span class="hljs-number">20px</span> <span class="hljs-number">0</span>;

}
input.euc-y-s[type="submit"]{background-color:#3498db;color:#fff;font-size:21px;box-shadow:none;-webkit-transition: .4s;-moz-transition: .4s;-o-transition: .4s;transition:.4s;-webkit-backface-visibility:hidden;position:relative;cursor:pointer;padding: 13px 20px;text-align: center;border-radius: 50px;-webkit-box-shadow: none; -moz-box-shadow: none; box-shadow: none;border: 0;height: auto;outline: medium;line-height: 20px;margin: 0;}

input.euc-y-i[type="text"]:hover,input.euc-y-i[type="password"]:hover{border:1px solid #56b4ef;box-shadow:0 0 4px #56b4ef;}

如何实现？在编辑文章是使用短码包围要隐藏的内容，如下即可。

【secret key=<span class="hljs-string">"密码"</span>】加密内容【/secret】
【secret key=<span class="hljs-string">"密码"</span>】加密内容【/secret】
【secret key="密码"】加密内容【/secret】

把上面中文括号改为英文括号【】→[]

本站使用输入密码可见示例

 

测试密码：123456

 

4、回复后可见

首先在主题functions.php文件中添加下面代码。

<span class="hljs-comment">//部分内评论可见</span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">reply_read</span><span class="hljs-params">($atts, $content=null)</span> </span>{
extract(shortcode_atts(<span class="hljs-keyword">array</span>(<span class="hljs-string">"notice"</span> => <span class="hljs-string">'<span style="color: #1abec7;"> *** 隐藏内容，回复后可见！*** </span>'</span>), $atts));
$email = <span class="hljs-keyword">null</span>;
$user_ID = (int) wp_get_current_user()->ID;
<span class="hljs-keyword">if</span> ($user_ID > <span class="hljs-number">0</span>) {
    $email = get_userdata($user_ID)->user_email;
<span class="hljs-keyword">if</span> ( current_user_can(<span class="hljs-string">'level_10'</span>) ) {
    <span class="hljs-keyword">return</span> <span class="hljs-string">'<span style="color: #08a007;">'</span>.do_shortcode( $content ).<span class="hljs-string">'</span>'</span>;
}
<span class="hljs-keyword">if</span> ($email == $admin_email) {

如何实现？在编辑文章是使用短码包围要隐藏的内容，下面列举的是两种方式，我们任选一种即可。

【hide】我是被隐藏的内容，样式一（默认样式）【/hide】
【hide】 notice=<span class="hljs-string">"自定义信息"</span>]我是被隐藏的内容，样式二（自定义回复信息）【/hide】
【hide】我是被隐藏的内容，样式一（默认样式）【/hide】
【hide】 notice=<span class="hljs-string">"自定义信息"</span>]我是被隐藏的内容，样式二（自定义回复信息）【/hide】
【hide】我是被隐藏的内容，样式一（默认样式）【/hide】
【hide】 notice="自定义信息"]我是被隐藏的内容，样式二（自定义回复信息）【/hide】

把上面中文括号改为英文括号【】→[]
