PHP：打开一个文件下载对话框 [英] PHP: open a file download dialog

问题描述

我有一个在Amazon S3中托管的MPEG文件（.mpg），我想链接到我拥有的一个页面，因此用户将能够从该页面下载它。
我在我的页面上有一个链接：
bla bla / p>

当我右键单击它并选择另存目标时，该文件的链接工作正常，但是当我点击它时，我希望它也能工作。它会打开一个文件下载对话框，现在，左键单击将直接进入一个有视频直接播放的页面（在FireFox中），或者只是不会加载（在Internet Explorer中）。

我在PHP中工作，为什么会发生这种情况？

解决方案

文件在一个下载PHP脚本中发送相应的 Content-Disposition 标题，告诉浏览器将其视为下载内容而不是内容项目。
$ b

例如：

  header（Content-Disposition：attachment; filename = yourfilenamehere.ext> ;）;

I have an MPEG file (.mpg) hosted in Amazon S3, that I want to link to a page I have, so the user will be able to download it from the page. I have in my page a link: bla bla"

The link to the file works when I right-click it and choose "Save Target As" , but I would like it to work also when I left click it, and that it will open a file download dialog. right now, a left click will direct to a page that has the video directly played in it (in FireFox) or just won't load (in Internet Explorer).

I am working in PHP, why does this happen?

解决方案

You probably want to wrap the file within a "download" PHP script that sends the appropriate Content-Disposition header telling the browser to treat it as a download instead of a content item.

For instance:

header("Content-Disposition: attachment; filename=yourfilenamehere.ext>");
