2、admin_upfile.php

date_default_timezone_set('PRC');
//这里上传 $upsize判断上传文件的大小
$uppath = isset($_REQUEST["upPath"]) ? $_REQUEST["upPath"] : "/attached/"; //文件上传路径
$formName = isset($_REQUEST["formName"]) ? $_REQUEST["formName"] : "myform"; //回传到上页面编辑框所在Form的Name
$editName = isset($_REQUEST["editName"]) ? $_REQUEST["editName"] : $_REQUEST["editName"]; //回传到上页面编辑框的Name
//转换根目录的路径
if (strpos($uppath, "/") == 0) {
$i = 0;
$thpath = $_SERVER["SCRIPT_NAME"];
$thpath = substr($thpath, 1, strlen($thpath));
while (strripos($thpath, "/") !== false) {
$thpath = substr($thpath, strpos($thpath, "/") + 1, strlen($thpath));
$i = ++$i;
}
$pp = "";

}
$uppaths = $pp . substr($uppath, 1, strlen($thpath));
}
$filename = date("y-m-d");
if (is_dir($uppaths . $filename) != TRUE)
mkdir($uppaths . $filename, 0777);
// if(is_dir($filename."/".$ctime)!=TRUE) mkdir($filename."/".$ctime,0777);
$f = $_FILES['file1'];

echo "<script>alert('只能上传图片格式的文件');window.close()</script>";
//echo $f['type'];
return false;
}
//获得文件扩展名
$temp_arr = explode(".", $f["name"]);
$file_ext = array_pop($temp_arr);
$file_ext = trim($file_ext);
$file_ext = strtolower($file_ext);
//新文件名
$new_file_name = md5(date("YmdHis")) . '.' . $file_ext;
//$new_file_name = md5(date("YmdHis") . '_' . rand(10000, 99999)) . '.' . $file_ext;
$dest = $uppaths . $filename . "/" . date("ymdhis") . "_" . $new_file_name; //设置文件名为日期加上文件名避免重复上传目录
$dest1 = $uppath . $filename . "/" . date("ymdhis") . "_" . $new_file_name; //设置文件名为日期加上文件名避免重复
$r = move_uploaded_file($f['tmp_name'], $dest);
