二找出要投票的标题和题目名称

3 <head>
4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
5 <title>无标题文档</title>
6 </head>

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>
