首先備份數(shù)據(jù)庫

1、選擇--系統(tǒng)》數(shù)據(jù)庫命令，注意dede替換為你的表名

ALTER TABLE dede_archives ADD zan int(11) NOT NULL DEFAULT '1200' AFTER weight;

繼續(xù)添加

CREATE TABLE IF NOT EXISTS `dede_zan` (  
  `id` int(11) NOT NULL AUTO_INCREMENT,  
  `aid` int(11) NOT NULL,  
  `ip` varchar(40) NOT NULL,  
  PRIMARY KEY (`id`)  
) ENGINE=MyISAM  DEFAULT CHARSET=utf8

2、打開文章模板，在自己需要的位置加入  

 <p  class="zan-num m-doc-qq-xx-zan" dir="{dede:field.id/}"><i class="iconfont icon-dianzan"></i><br />
            <span data-role="like" class="zan-size">{dede:field.id function="zan(@me)"/}</span> </p>

核心代碼為最大層加class為zan-num 控制點擊，dir 控制文章ID   ,zan-size控制點贊成功的數(shù)字

底部加入腳本，需要引入jq

<script language="javascript" type="text/javascript">
$(function(){  
    $(".zan-num").click(function(){  
        var zan = $(this); 
        var id = zan.attr("dir"); //對應id  
       // zan.find("i").fadeOut(300); //漸隱效果  
        $.ajax({  
            type:"POST",  
            url:"/zan.php",  
            data:"id="+id,  
            cache:false, //不緩存此頁面  
            success:function(data){  
                zan.find(".zan-size").html(data);  
                zan.css("background-color","#f88120").fadeIn(300); //漸顯效果  
            }  
        });  
        return false;  
    });  
}); 
</script>

3、在/include/extend.func.php 最后加入函數(shù)zan

function zan($aid) 
{ 
    global $dsql; 
    $row = $dsql->GetOne("Select id,zan From dede_archives where id='".$aid."'"); 
    return $row['zan']; 
    }

4、最后在根目錄加入加入zan.php

<?php 
require_once (dirname(__FILE__) . "/include/common.inc.php"); 
$ip =getip(); //獲取用戶IP  
$id = $_POST['id'];  
if(!isset($id) || empty($id)) exit;  
  
//查詢已贊過的IP 
$dsql->SetQuery("SELECT ip FROM dede_zan  WHERE aid='".$id."' and ip='$ip'"); 
$dsql->Execute(); 
$count = $dsql->GetTotalRow(); 
  
if($count==0){ //如果沒有記錄  
  
    $dsql->ExecuteNoneQuery("update dede_archives set zan=zan+1 where id='$id'; ");//寫入贊數(shù) 
      
    $dsql->ExecuteNoneQuery("insert into dede_zan (aid,ip) values ('$id','$ip'); ");//寫入IP,及被贊的AID  
  
    $rows = $dsql->GetOne("Select zan  from dede_archives where id='".$id."'");//獲取被贊的數(shù)量 
    $zan = $rows['zan']; //獲取贊數(shù)值  
    echo $zan;  
}else{  
    echo "贊過了..";  
}
