php在线问卷调查程序二-PHP源码

好了,html 页面的css与js都写好了下面我们来看看数据库与php程序是如何实现的吧,我们先来看看数据库结构.

CREATE TABLE IF NOT EXISTS `su_mon_vote` (
`id` int(11) NOT NULL auto_increment,
`v1` varchar(100) default NULL,
`v2` varchar(200) NOT NULL,
`v3` varchar(200) NOT NULL,
`v4` varchar(200) NOT NULL,
`v5` varchar(200) NOT NULL,
`v6` varchar(200) NOT NULL,
`name` varchar(50) NOT NULL,
`tel` varchar(50) NOT NULL,
`email` varchar(50) NOT NULL,
`address` varchar(200) NOT NULL,
`vip` varchar(20) NOT NULL,
`vdate` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=gb2312 AUTO_INCREMENT=6 ;上面的结构是随便写的没注意数据库其它方面报.好下面我们来看看php程序是怎么判断调查的吧.

if(empty($_COOKIE["cook"])){
mysql_connect('localhost','root','mailangel') or die('database server no exists!');
mysql_select_db('vot') or die('database error!');
mysql_query("SET NAMES 'gbk'");//set document charset encode
$name =get_value("name",'post');

$value =$_SERVER['HTTP_HOST'];

$array =array();
for($i=1;$i<=6;$i++){
$v ='v'.$i;
$v =get_value("$v",'post');
$array[$i-1]=$v;

}

$sql =$sql."'".$array[0]."','".$array[1]."','".$array[2]."','".$array[3]."','".$array[4]."','".$array[5]."','$name',";
$sql =$sql."'$email','$add','$vip','$date','$tel')";
//mysql_query($sql) or die($sql.mysql_error());
if( mysql_query($sql)){
setCOOKIE("cook", $value, time()+7200, "/");
alert('答题成功,谢谢你的参与!','index.html');

}else{

}

}else{
print "答题失败,一人只能参加一次答题!，点击返回";
}

function get_value($para,$para2){//获取参数的值
if( 'post'==$para2 ){
return addslashes(isset($_POST[$para])?$_POST[$para]:'');
}else{

}
}

function alert($str,$para){//提示设置函数，
if( ''== $para){
exit("");
}else{
exit("");
}
}

function get_real_ip(){
