MySql字段加1出错

Jun 06, 2016 pm 08:23 PM
mysql php web

很多天前就发现的问题,当时以为是自己机器问题,现在上传云服务器还是没能解决,望大神助我~
首先是我的个人博客文章在Mysql里有个Look字段,每次查看这个博客,这个字段便在原值上加1,但问题是我每次点击查看它总是原值加2,这真的令我费解,看源码

<code>public function viewBlog(){
        $_sql='SELECT *
            FROM blog
            WHERE id='.$this->_id.' AND verify=1';
        $_sqlView='UPDATE blog SET `look`=`look`+1 WHERE id='.$this->_id;
        parent::aud($_sqlView);
        return parent::getOne($_sql);
    }
    </code>
Copy after login
Copy after login

这是Model里的源码

<code>private function viewBlog(){
            $this->_model->_id=Tool::checkInt(@$_GET['id']);
            $_oneBlog=$this->_model->viewBlog();
            $this->_tpl->assign('oneBlog',$_oneBlog);
        </code>
Copy after login
Copy after login

这是控制器的源码片段,已确定viewBlog()函数只执行了一遍,更诡异的是如果我点击评论(评论和查看相比a标签只多了一个#anchor锚点定位到评论框)它的look值便会加3,然后再点击查看或评论它便正常加1了。。。。。。
求大神告知个人博客这是我的博客地址,并不是求访问量,真的求大神解答~~~

你先不要直接存进数据库先,测试一下look=look+1是不是这里有问题,看看是不是真的访问了一次
