一个程序下载的管理程序(三)

//后台程序sign.php(做为现在的主流开发语言)源代码如下:
<?require("../opendata.php(做为现在的主流开发语言)");?>
<?
if($action=="sign")
{
if($say==""||$title==""||$url==""||$size=="")
{
header("location:../message.php(做为现在的主流开发语言)?message=资料不完整&redirect=download/download.php(做为现在的主流开发语言)?page=0%26action=publish");
break;
} $say=htmlspecialchars($say);
 $title=htmlspecialchars($title);
 $say=str_replace(" "," ",$say);
 $say=nl2br($say);
 $now_time=getdate();
 $ttime=$now_time["year"]."-".$now_time["mon"]."-".$now_time["mday"]." ".$now_time["hours"].":".$now_time["minutes"].":".$now_time["seconds"];
 $str="insert into download (title,say,click,ttime,url,size,type) values (".$title.",".$say.",0,#".$ttime."#,".$url.",".$size.",".$type.")";
 MySQL(和PHP搭配之最佳组合)_query($str,$cn);

header("location:download.php(做为现在的主流开发语言)?page=0&action=show");
}
if($action=="download")
{
 MySQL(和PHP搭配之最佳组合)_query("update download set click=click+1 where id=".$id,$cn);

?>
<?

if(header("location:$url"))
echo "error";
?>
<html>
<a href="<?=$url?>">如果你的浏览器没有弹出下载窗口,请点这里</a>

<a href="javascript:self.close()">关闭窗口</a>
 
</html>
<?}?>
<?if($action=="mail")
{
