wordpress文章点赞功能

3、在当前主题的single.php文件的代码下面添加点赞按钮调用代码：

<div class="post-like">
	<a href="javascript:;" data-action="ding" data-id="<?php the_ID(); ?>" class="favorite<?php if(isset($_COOKIE['bigfa_ding_'.$post->ID])) echo ' done';?>">喜欢 <span class="count">
	<?php 
		if( get_post_meta($post->ID,'bigfa_ding',true) ){            
			echo get_post_meta($post->ID,'bigfa_ding',true);
		} else {
			echo '0';
		}
	?></span>
	</a>
 </div>

4、在当前主题的style.css文件中添加点击按钮样式（仅供参考）：

.post-like{text-align:center;padding:10px}
.post-like a{ background-color:#21759B;border-radius: 3px;color: #FFFFFF;font-size: 12px;padding: 5px 10px;text-decoration: none;outline:none}
.post-like a.done, .post-like a:hover{background-color:#eee;color:#21759B;} 
.post-like a.done{cursor:not-allowed}
