EMLOG博客非插件实现一键点赞功能介绍

本代码来源于网络，具体谁先写出来，舍力表示不知道，本站只做收集分享之用途，本人也不喜欢用插件，好了，废话不多说，下面舍力说说具体的操作方法
用法很简单，在module.php里面加如以下代码

 //点赞 function syzan(){ $DB = MySql::getInstance(); if($DB->num_rows($DB->query("show columns from ".DB_PREFIX."blog like 'slzan'")) == 0){ $sql = "ALTER TABLE ".DB_PREFIX."blog ADD slzan int unsigned NOT NULL DEFAULT '0'"; $DB->query($sql);}}syzan(); function update($logid){ $logid = intval($_POST['id']); $DB = Database::getInstance(); $DB->query("UPDATE " . DB_PREFIX . "blog SET slzan=slzan+1 WHERE gid=$logid"); setcookie('slzanpd_'. $logid, 'true', time() + 31536000);} function lemoninit() {if( @$_POST['plugin'] == 'slzanpd' &&@$_POST['action'] == 'slzan' &&isset($_POST['id'])){ $id = intval($_POST['id']); header("Access-Control-Allow-Origin: *"); update($id);echo getnum($id);die;}}lemoninit(); function getnum($id){ static $arr = array(); $DB = Database::getInstance(); if(isset($arr[$logid])) return $arr[$logid]; $sql = "SELECT slzan FROM " . DB_PREFIX . "blog WHERE gid=$id"; $res = $DB->query($sql); $row = $DB->fetch_array($res); $arr[$id] = intval($row['slzan']); return $arr[$id];} ?>

<a class="slzanpd" data-slzanpd="" title="喜欢这篇文章就赞一个吧！">赞 ( echo(isset($logData['slzan'])?$logData['slzan']:getnum($logData['logid']));?>次)a>

$(document).on('click', '.slzanpd', function() { var a = $(this), id = a.data('slzanpd'); if (slzanpd_check(id)) { alert('您已赞过本文！'); } else { $.post('', { plugin: 'slzanpd', action: 'slzan', id: id }, function(b) { a.find('u').html(b); slzanpd_(a); }); } }); function slzanpd_check(id) { return new RegExp('slzanpd_' + id + '=true').test(document.cookie); } $('[data-slzanpd]').each(function() { var a = $(this), id = a.data('slzanpd'); if (slzanpd_check(id)) { slzanpd_(a); } else { a.attr('title', '给舍力来点动力吧！') } }); function slzanpd_(a) { a.css('cursor', 'not-allowed').attr('title', '您已赞过本文！'); }
