</table>
</span>
</body>
</html>
The writing is a bit verbose, a bit stupid but very practical
<?php
include 'connect.php';
$name=$_POST['phone'];
$sql="insert into countone values(null,$name,now(),null)";
mysql_query($sql);
?>
<script type="text/javascript">
alert ("投票成功！");
location="question.php";
</script>
Link to mysql:
<?php
mysql_connect("localhost","root","");
mysql_select_db("vote");
mysql_query("set names utf8");
?>
