一个容易的PHP投票系统

建立2个表,一个用来显示当前主题,一个存放历史结果。
当前主题表结构:选项(包括主题),票数
历史结果表结构:id,主题名,关点,投票开始时间,投票结束时间


管理页面:
功能:1、更新投票主题 2、查看历史结果 3、停止使用投票系统

一、建表
CREATE Table toupiaoall(
  id int(4) NOT NULL auto_increment,
  theme char(20) NOT NULL,
  idea char(100) NOT NULL,
  begin char(20) NOT NULL,
  end char(20) NOT NULL,
  PRIMARY KEY (id)
);
CREATE TABLE toupiaocur(
  xx varchar(20) NOT NULL,
  ps int(6) not null,
  date char(10) not null
);
说明:在表toupiaocur中,第一个记录存放主题和建立时间,在进行投票时不改动。从第二个记录开始记录各选项内容和票数。

链接程序:connect.inc.php3
<?
$show="yes";
$xuanxiang=array("","one","two","thr","fou","fiv");
$current="toupiaocur";
$alldata="toupiaoall";
@mysql_connect("localhost","","") or die ("sorry,unable to connect to database");
@mysql_select_db("db") or die ("unable to select database");
?>

二、显示页面
<?
//页面
include("connect.inc.php3");
$query_tp="select * from $current";
$result_tp=mysql_query($query_tp);
$row_tp=@mysql_fetch_array($result_tp);
$rows_tp=@mysql_num_rows($result_tp);
if ($rows_tp) {
?>
<hr size="1">
<script language="JavaScript">
<!--
function newin() {
var newwin=window.open("","homeWin","toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=no,width=240,height=180");
return false;
}
//-->
</script>
<form name="fromtp" action="toupiao_pre.php" method="post" onsubmit="newin('')" target=homeWin>
<center>【网上调查】</center><br>
<?
echo " <font color=#cc3300>".$row_tp[0]."</font><br>"; //显示主题
//显示每个选项
for ($t=1;$t<$rows_tp;$t++){//从1开始是为了不选主题,原因嘛。。想想表的结构吧
$seek=mysql_data_seek($result_tp,$t);
$list_tp=mysql_fetch_row($result_tp);
?>
 <input type="radio" name="piaosu" value="<? echo $list_tp[0]."\"";if ($t==1)  echo "checked"; ?> ><? echo $list_tp[0]; ?><br>
<?
}


?>
<div align=center><br><input type="submit"  name="Submittp" value="投票/查看" style="background-color: rgb(235,235,235)"></div>
</form>

<?
}

?>


三、管理页面

<?

include("connect.inc.php3");

//功能:1、更新投票主题(同时将上期投票结果放到历史中) 2、查看历史结果 3、修改历史结果
?>
<form name="form1" action="<? echo $PHP_SELF; ?>" method="get" >
<font color=#ff9900><center>更新主题:</font><select name="select">
   <option selected>选项数目</option>
   <option value="2">2</option>
   <option value="3">3</option>
   <option value="4">4</option>
   <option value="5">5</option>
</select>
<input type="submit" name="Submit_tp" value="确定">


<?
echo "  <a href=\"$PHP_SELF?vhistory=yes\"><font color=#ff9900>查看历史记录</font><a>  ";
echo "<a href=\"$PHP_SELF?stop=yes\"><font color=#ff9900>停止使用投票系统</font></a>  ";
echo "<a href=\"admin.php3\"><font color=#ff9900>文章管理</font></a>";
echo "</center></form> <hr size=\"1\" color=\"#ff9900\">";
if ($Submit_tp) {
?>
<SCRIPT language=JavaScript>
<!--
var submitcount=0;
function check_com(){
if(document.form_tp.theme.value.length ==0){
     submitcount--;
     alert("主题没有填写!\nYou must supply a subject.");
     return false;
  }
 
<?
for ($t=1;$t<=$select;$t++) {
?>
  if(document.form_tp.<? echo $xuanxiang[$t]; ?>.value.length ==0){
     submitcount--;
     alert("选项没有填写完整\nYou must supply a option.");
     return false;
  }
  
<?
}
?>

}
//-->
</SCRIPT>
<form name="form_tp" onsubmit="return check_com()" action="<? echo $PHP_SELF; ?>" method="post" >
<table width="100%" border="0" cellspacing="0" cellpadding="0">

} //9
echo "<center>3秒后返回</center><meta http-equiv=\"refresh\" content=\"3;url=$PHP_SELF\">";

//显示历史结果

   }
?>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr bgcolor="#EAEAEA">
   <td height="20"><? echo "【主题】 ".$rows[theme]."  【开始时间】 ".$rows[begin]."  【结束时间】 ".$rows[end]."   [共".$all."人参加投票]  <a href=\"$PHP_SELF?del=yes&id=$rows[id]\"><font color=red>[删除]</font></a>"; ?></td>

?>

四、处理页面(计数页面)
<?
//显示页面

include("connect.inc.php3");
$query="update $current set ps=ps+1 where binary xx like \"$piaosu\""; //*选中的票数加1 ,binary是为了精确匹配
$update=mysql_query($query);
$query_tp="select * from $current";
$result_tp=mysql_query($query_tp);
$result_all=mysql_fetch_array($result_tp);
$result_tp_num=mysql_num_rows($result_tp);
echo "<title>$result_all[0]</title>";

for ($i=1;$i<$result_tp_num;$i++) {
$seek=mysql_data_seek($result_tp,$i);
$row=mysql_fetch_row($result_tp);
$ps[$i]=$row[1];//*把票数放到数组ZHUTI中
$zhuti[$i]=$row[0];//*把选项放到数组ZHUTI中
$piaosuall=$piaosuall+$ps[$i];//*总票数
}
echo "<font color=#cc3300>".$result_all[0]."</font>(共".$piaosuall."人参加投票)<br><br>";   //*显示主题



for ($k=1;$k<$result_tp_num;$k++) {
$percent=round($ps[$k]/$piaosuall*10000)/100;//*计算每个选项所占的百分比
echo $zhuti[$k].":".$ps[$k]."人   (".$percent."%)<br>";//*显示每个选项
}
?>
