php 是这样的
<?php
include_once("include/main.php");

$flag=($_POST["flag"]=="")? $_GET["flag"]:$_POST["flag"];

$Magazinefile=($_POST["Magazinefile"]=="")? $_GET["Magazinefile"]:$_POST["Magazinefile"];

$Year=($_POST["year"]=="")? $_GET["year"]:$_POST["year"];
$Mont=($_POST["mont"]=="")? $_GET["mont"]:$_POST["mont"];
$Day=($_POST["day"]=="")? $_GET["day"]:$_POST["day"];
if($Day != ""){
$Hf_day=$Year."年".$Mont."月".$Day."日";
}else{
$Hf_day=="";
}

if($flag=="insert"){
echo $filename1=$_FILES['userfile1']['name'];#文件名称
echo $filename2=$_FILES['userfile2']['name'];

echo $filetmp1=$_FILES['userfile1']['tmp_name'];#上传临时文件目录
$filetmp2=$_FILES['userfile2']['tmp_name'];

#文件上传后存放的路径
echo $uploaddir="F:\Haley"."\\" ;

$HMagazineID=$Mid=mysql_num_rows(mysql_query("select * from magazine where flag!='U'"))+1;

$sql="insert into magazine (MagazineID,subday,flag,content) values ('$HMagazineID','$Hf_day','D','$content')";

if(move_uploaded_file($filetmp1,$uploaddir.$filename1)){
echo "文件上传成功！";
copy($uploaddir.$filename1,$uploaddir."\bak"."\\".$filename1);
echo $filename1;
}
