为WordPress文章添加打赏功能

网上看到很多博客打赏功能，感觉这种类型的打赏功能还不错，就记下来

效果图如上

1、添加CSS样式表到你的blog主题的SYLE.CSS中：

.reward { 
         padding: 5px 0
}
.reward .reward-notice {
    font-size: 14px; 
    line-height: 14px;
    margin: 15px auto;
    text-align: center
}
.reward .reward-button { 
    position: relative; 
    display: block; 
    width: 48px; 
    height: 48px;
    margin: 0 auto;
    padding: 0;
    -webkit-user-select: none;
    text-align: center; 
    vertical-align: middle;
}

.reward .reward-code {
.reward .reward-code {
    position: absolute; 
    top: -220px; 
    left: 50%;
    display: none;
    width: 350px;
    height: 200px;
    margin-left: -175px;
    padding: 15px;
    border: 1px solid #e6e6e6;
    background: #fff;
    box-shadow: 0 1px 1px 1px #efefef
}
.reward .reward-button:hover .reward-code { 
    display: block
}
.reward .reward-code span { 
    display: inline-block;
    width: 150px;
    height: 150px
}
.reward .reward-code span.alipay-code {
    float: left
}
.reward .reward-code span.alipay-code a { 
    padding: 0
}
.reward .reward-code span.wechat-code {
    float: right
}
.reward .reward-code img {
    display: inline-block;
    float: left;
    width: 150px;
    height: 150px;
    margin: 0 auto;
    border: 0
}
.reward .reward-code b {
    font-size: 14px; 
    line-height: 26px; 
    display: block; 
    margin: 0; 
    text-align: center;
    color: #666
}
.reward .reward-code b.notice {
    line-height: 2rem;
    margin-top: -1rem;
    color: #999
}
.reward .reward-code:after,.reward .reward-code:before {
    position: absolute; content: '';
    border: 10px solid transparent
}
.reward .reward-code:after {
    bottom: -19px;
    left: 50%;
    margin-left: -10px;
    border-top-color: #fff
}
.reward .reward-code:before {
    bottom: -20px; 
    left: 50%;
    margin-left: -10px;
    border-top-color: #e6e6e6
}

2、在你的博客模版function.php中加入：(注意图片路径改为你自己的相关img地址)

{function add_after_post_content($content) { 
if(!is_feed() && !is_home() && is_singular() && is_main_query()) { 
$content .= '<div class="reward"> 
<div class="reward-button"> <img src="/wp-content/themes/XXXXXX/images/reward.png" style="display: inline;"> 
<span class="reward-code"><span class="alipay-code"><img class="alipay-img" 
src="https://dacat.cc/wp-content/uploads/2017/09/3504alipay.png"><b>支付宝扫码打赏</b></span><span class="wechat-code"><img class="wechat-img" 
src="https://dacat.cc/wp-content/uploads/2017/09/wecat.png"><b>微信打赏</b></span></span> 
</div> 
<p class="reward-notice"> 如果文章有帮助到您，欢迎移至上方按钮打赏大喵
 </p>
</div>';
 }
 return $content;
}
add_filter('the_content', 'add_after_post_content');

3、最后添加以下JS到你主题的JS脚本中，该JS主要实现平板或手机中改为点击弹出二维码
