下载文件的脚本一次只能下载1个？ [英] Script to download files only allows 1 download at a time?

问题描述

我有一个基于传递给页面的id的脚本，它从文件数据库中检索文件名和路径，然后输出要下载的文件。我特意这样做了（参见下面的代码），因此用户可以选择保存。或跑步文件。

问题在于，当单击文件进行下载时，使用此方法，用户无法选择要下载的其他文件。看起来这个脚本阻止服务器一次允许多个下载。我不太了解这个，所以任何帮助都会非常感激!!!

谢谢，

这里的代码提示下载

[PHP]

开关（$ extlwr）{

case（$ extlwr ==" .zip"）：

$ commonname = " zip";

$ ct =" Content-type：application / octet-stream" ;;

break;

case（$ extlwr ==" .mp3"）：

$ commonname =" mp3";

$ ct =" Content-type：audio / mp3" ;;

休息;

case（$ extlwr ==" .pdf"）：

$ commonname =" pdf";

$ ct =" Content-type：application / pdf" ;;

break;

case（$ extlwr ==" .doc"）：

$ commonname =" doc" ;;

$ ct =" Content-type：application / ms-word" ;;

break;


}

$ size = strval（filesize（" $ filepath $ locat）离子））;


header（" Pragma：public"）;

header（" Expires：0"）;

header（Cache-Control：must-revalidate，post-check = 0，pre-check = 0）;

header（Cache-Control：private，false） ;

标题（" $ ct"）;

标题（''内容 - 处置：附件; filename ="''。$ filename。''" ;;''）;

header（" Content-Transfer-Encoding：binary"）;

if （$ extlwr！=" .pdf"）{

header（''Content-Length：''。$ size）;

}

readfile（" $ filepath $ location"）;

退出;

[/ PHP]


任何想法？

再次感谢

Hi,
I have a script which based on an id passed to the page is retrieving a filename and path from the database of a file and then outputting the file for download. I specifically did it this way (see the code below) so user would have a choice of "Saving" or "Running" the file.
The problem is that with this method when a file is clicked for download the user cant then select another file to download. It seems like this script prevents the server from allowing more than one download at a time. I dont know much about this, so any help would be really appreciated!!!
Thanks,
here is the code which prompts the download
[PHP]
switch($extlwr) {
case ($extlwr == ".zip"):
$commonname="zip";
$ct = "Content-type: application/octet-stream";
break;
case ($extlwr == ".mp3"):
$commonname="mp3";
$ct = "Content-type: audio/mp3";
break;
case ($extlwr == ".pdf"):
$commonname="pdf";
$ct = "Content-type: application/pdf";
break;
case ($extlwr == ".doc"):
$commonname="doc";
$ct = "Content-type: application/ms-word";
break;

}
$size = strval(filesize("$filepath$location"));

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("$ct");
header(''Content-Disposition: attachment; filename="''.$filename.''";'');
header("Content-Transfer-Encoding: binary");
if($extlwr != ".pdf"){
header(''Content-Length: ''.$size);
}
readfile("$filepath$location");
exit;
[/PHP]

any ideas?
thanks again
