wordpress文章点赞功能目前已经相对普遍，很多插件和分享代码都自带此功能。而且样式各异足以满意wp小白用户的需要，但是如果想打造一款自己想要的点赞功能样式，还是要手动添加下代码才能实现。下面给大家推荐一种纯代码实现文章页面点赞的方法。用自定义字段保存赞数量，通过cookies来禁止重复赞。

加入至Functions.php文件中：

area data-settings="dblclick" readonly >add_action('wp_ajax_nopriv_bigfa_like', 'bigfa_like');add_action('wp_ajax_bigfa_like', 'bigfa_like');function bigfa_like(){global $wpdb,$post;$id = $_POST["um_id"];$action = $_POST["um_action"];if ( $action == 'ding'){$bigfa_raters = get_post_meta($id,'bigfa_ding',true);$expire = time() + 99999999;$domain = ($_SERVER['HTTP_HOST'] != 'localhost') ? $_SERVER['HTTP_HOST'] : false; // make cookies work with localhostsetcookie('bigfa_ding_'.$id,$id,$expire,'/',$domain,false);if (!$bigfa_raters || !is_numeric($bigfa_raters)) {update_post_meta($id, 'bigfa_ding', 1);} else {update_post_meta($id, 'bigfa_ding', ($bigfa_raters + 1));} echo get_post_meta($id,'bigfa_ding',true);} die;}area>161718192021222324add_action('wp_ajax_nopriv_bigfa_like', 'bigfa_like');add_action('wp_ajax_bigfa_like', 'bigfa_like');function bigfa_like(){global $wpdb,$post;$id = $_POST["um_id"];$action = $_POST["um_action"];if ( $action == 'ding'){$bigfa_raters = get_post_meta($id,'bigfa_ding',true);$expire = time() + 99999999;$domain = ($_SERVER['HTTP_HOST'] != 'localhost') ? $_SERVER['HTTP_HOST'] : false; // make cookies work with localhostsetcookie('bigfa_ding_'.$id,$id,$expire,'/',$domain,false);if (!$bigfa_raters || !is_numeric($bigfa_raters)) {update_post_meta($id, 'bigfa_ding', 1);} else {update_post_meta($id, 'bigfa_ding', ($bigfa_raters + 1));} echo get_post_meta($id,'bigfa_ding',true);} die;}

相对应的JS代码：

area data-settings="dblclick" readonly >$(document).ready(function() { $.fn.postLike = function() { if ($(this).hasClass('done')) { return false; } else { $(this).addClass('done'); var id = $(this).data("id"), action = $(this).data('action'), rateHolder = $(this).children('.count'); var ajax_data = { action: "bigfa_like", um_id: id, um_action: action }; $.post("./wp-admin/admin-ajax.php", ajax_data, function(data) { $(rateHolder).html(data); }); return false; }};$(document).on("click", ".favorite",function() { $(this).postLike();});}); area>1617181920212223242526$(document).ready(function() { $.fn.postLike = function() { if ($(this).hasClass('done')) { return false; } else { $(this).addClass('done'); var id = $(this).data("id"), action = $(this).data('action'), rateHolder = $(this).children('.count'); var ajax_data = { action: "bigfa_like", um_id: id, um_action: action }; $.post("./wp-admin/admin-ajax.php", ajax_data, function(data) { $(rateHolder).html(data); }); return false; }};$(document).on("click", ".favorite",function() { $(this).postLike();});});

调用代码：

area data-settings="dblclick" readonly > <div > <a href="javascript:;" data-action="ding" data-id="<?php the_ID(); ?>" >喜欢 <span ><?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>area>123456789 <div > <a href="javascript:;" data-action="ding" data-id="<?php the_ID(); ?>" >喜欢 <span ><?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>

参考CSS样式

area data-settings="dblclick" readonly >.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}area>1234.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}
