PHP类的封装和做投票和用进度条显示

 三处理传过来的数据
1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 2 <html xmlns="http://www.w3.org/1999/xhtml">
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 5 <title>无标题文档</title>
 6 </head>
 7 
 8 <body>
 9 <!--接收用户传过来的的数据-->
10 <?php
11 include("./DBDA.class.php");
12 $db = new dbda();
13 $attr = $_POST["xx"];
14 //var_dump($attr);
15 
16 foreach($attr as $v)
17 {
18     $sql = "update diaoyanxuanxiang set numbers=numbers+1 where ids='{$v}'";
19     $db->Query($sql,0);
20 }
21 //显示结果
22 $sql = "select * from diaoyanxuanxiang";
23 $shuzu = $db->Query($sql);
24 
25 $szs = "select sum(numbers) from diaoyanxuanxiang";
26 $azs = $db->Query($szs);
27 $zs = $azs[0][0];
28 
29 foreach($shuzu as $v)
30 {
31     $bfb = ($v[2]/$zs)*100;
32     echo "{$v[1]}：{$v[2]}({$bfb}%)<div style='200px;height:10px; border:1px solid red;'><div style=' {$bfb}%; height:10px'></div></div>";
33 }
34 
35 
36 
37 ?>
38 
39 </body>
40 </html>

二找出要投票的标题和题目名称

1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 2 <html xmlns="http://www.w3.org/1999/xhtml">
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 5 <title>无标题文档</title>
 6 </head>
 7 
 8 <body>
 9 <form action="jieguo.php" method="post">
10 <?php
11 include("./DBDA.class.php");
12 $db = new DBDA();
13 
14 $sql = "select * from diaoyantimu";
15 
16 $attr = $db->Query($sql,1);//成员方法里面类默认是1所以这里面要是查询的话1可以省掉不写。查询语句要返回二维数组$attr
17 
18 echo "{$attr[0][1]}<br>";//这是输出题目的标题和题目的名称:晚上够干啥？
19 //根据题目的代号查出所有选项
20 $code = $attr[0][0];
21 $sxx = "select * from diaoyanxuanxiang where timudaihao='{$code}'";
22 
23 $axx = $db->Query($sxx);//这个二位数组存着所有的选项信息
24 
25 foreach($axx as $v)
26 {    //echo "$v[1]<br>";//输出所有选项
27     //<input type='checkbox复选框
28     //value='{$v[0]}每个选项的代号
29     
30     echo "<input type='checkbox' value='{$v[0]}' name='xx[]' />$v[1]<br>";    
31 }
32 
33 ?>
34 
35 <input type="submit" value="投票" />
36 </form>
37 </body>
38 </html>
