实现原理
赞数通过自定义字段保存，赞数通过cookies禁止重复表扬。
代码部署
添加以下代码function.php
add_action(wp_ajax_nopriv_bigfa_like, igfa_like); add_action(wp_ajax_bigfa_like, igfa_like); function bigfa_like(){global $wpdb,$post;$id = $_POST["um_id"];$action = $_POST["um_action"];if ( $action == ding){$bigfa_raters = get_post_meta($id,igfa_ding,true);$expire = time() 99999999;$domain = ($_SERVER[HTTP_HOST] != localhost) ? $_SERVER[HTTP_HOST] : false; // make cookies work with localhostsetcookie(igfa_ding_.$id,$id,$expire,/,$domain,false);if (!$bigfa_raters
