The specific code is as follows

<?php

      //I方法接收页面传递来的值
      $num = I(&#39;num&#39;) ; 
      $password = I(&#39;password&#39;) ;
      //查找user表中num等于$num的值
      $datanum = $User->where(array(&#39;num&#39;=>$num))->find();
      //判断$datanum的值
      if ($datanum){
        if (md5($password) === $datanum[&#39;password&#39;]) { 
          if ($datanum[&#39;status&#39;] == 0) {
            $this->error(&#39;用户处于未审核状态，请联系管理员&#39;);
