1. Main voting page:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>投票</title>
</head>
  
<body>
  
<form action="TouChuLi.php" method="post">
<?phpinclude ("DBDA.class.php");$db=new DBDA();//从调研题目表中找出题目代号和名称
$sql="select * from diaoyantimu limit 0,1";
$arr=$db->query($sql);
$tmmc=$arr[0][1];$tmdh=$arr[0][0];echo "<p><h2>{$tmmc}:</h2></p>";
//从调研选项表中输出选项内容：
$sqlxx="select * from diaoyanxuanxiang where timudaihao=&#39;{$tmdh}&#39;";
$arrxx=$db->query($sqlxx);
echo "<p id=&#39;list&#39;>";
foreach ($arrxx as $v)
{  echo "<p><input type=&#39;checkbox&#39; value=&#39;{$v[0]}&#39; name=&#39;xx[]&#39;>{$v[1]}</p><br />";
}  
?>
<input type="submit" value="提交">
<input type="button" value="查看结果" id="check" onclick="Showjieguo()">
</form>
</p>
  
<p id="jieguo" style="display:none">
<?php//计算总人数：$sqlzs="select sum(numbers) from diaoyanxuanxiang where timudaihao=&#39;{$tmdh}&#39;";$zrs=$db->query($sqlzs);  
foreach ($arrxx as $v)
{    
  $name=$v[1];  $number=$v[2];  if($zrs[0][0]==0)
   {     $bfb = 0;
   }   else
   {     $bfb = ($number/$zrs[0][0])*100;
   }  $bfb=round($bfb,2);  echo "<p>
    <span class=&#39;x&#39;>{$name} </span>
    <p class=&#39;x&#39; style=&#39;width:200px; height:10px; background-color:#808080&#39;>
    <p style=&#39;width:{$bfb}%; height:10px; background-color:#FF8040&#39;> </p>
    </p>
    <span class=&#39;x&#39;>{$number} </span>
    <span class=&#39;x&#39;>{$bfb}% </span>
    </p>
    <br />    "; 
}?>
<input type="button" value="返回" id="fanhui" onclick="Showfanhui()">
</p>
<script>function Showjieguo()
{
  document.getElementById("list").style.display="none";
  document.getElementById("jieguo").style.display="block";
  }function Showfanhui()
{
  document.getElementById("list").style.display="block";
  document.getElementById("jieguo").style.display="none";
  }</script>
  
</body>
</html>

2. Processing voting page:

<?php$arr=$_POST["xx"];include ("../DBDA.class.php");$db=new DBDA();  
  
foreach($arr as $v)
{  $sql = "update diaoyanxuanxiang set numbers = numbers+1 where ids = &#39;{$v}&#39;";  
$db->Query($sql,1);//1代表$sql的类型
}
header ("location:TouPiao.php");
?>

3. Create Class for accessing the database, encapsulated for reference:

<?php//执行一个sql语句，返回相应的结果class DBDA
{  public $host="localhost";//数据库服务器地址
  public $uid="root";//数据库用户名
  public $password="";//数据库密码
  //执行SQL语句的方法
  //参数里面：$sql代表要执行的sql语句；$type是sql语句的类型，0代表查询，1代表其他(增删改)；$db代表要操作的数据库
  function Query($sql,$type=0,$db="0710_info")
  {    //造连接对象
    $dbconnect=new MySQLi($this->host,$this->uid,$this->password,$db);    //判断连接是否出错
    !mysqli_connect_error() or die("连接失败！");    //执行sql语句
    $result=$dbconnect->query($sql);    //判断SQL语句类型
    if($type==0)
    {       //如果是查询语句返回结果集的二维数组
      return $result->fetch_all();
      }    else
    {      //如果是其他语句，返回true或false
      return $result;
      }   
    }
      
  }
