php - 文件下载框

发布于 2024-08-10 02:03:18 字数 345 浏览 12 评论 0原文

我给用户一个下载 csv 文件的链接...只需使用

Click <a href="report.csv">here</a> to download your file.

此文本和链接将显示在一个小弹出窗口中 - 高度 100 宽度 400。

如果用户单击“保存”-那么文件就没有问题保存到他们选择的任何位置

如果他们选择“打开”,则 csv 文件会显示在小弹出窗口中。这不是我想要的 - 我更喜欢 Excel 打开并在 Excel 中显示文件,甚至禁用“打开”按钮可能是一个可能的选择。

我有什么想法可以实现吗?

谢谢,

I'm giving a user a link to download a csv file ...just using

Click <a href="report.csv">here</a> to download your file.

This text and link is being displayed in a small popup window - height 100 width 400.

If the user clicks "save" - then no problem then the file is saved to wherever they choose

If though they choose "open" the csv file is then displayed in the small popup window. Which isn;t what I want - I'd prefer excel to open and display the file in excel, or even disabling the "open" button may be a possible option.

Any ideas how I can achieve either?

Thanks,

我假设您正在使用一些 javascript 打开该弹出框..所以我建议不要显示/打开您的小“下载”弹出框,而是在网页上显示此链接。因此,当有人单击链接时,会强制浏览器下载文件,如果他们希望打开该文件,他们可以并且可能会获得与浏览器窗口大小一样宽的视图。

// 例如,要强制下载 zip 文件,请将标头发送为

// Set headers
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$file");
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");

I assume that you are opening that popup box using some javascript .. so I'd suggest to dont show/open your tiny "download" popup box and instead show this link on a webpage. So when somebody clicks on the link force the browser to download the file and if they wish to open it they can and probably get a view which is as wide as of browswer's windows size.

// just for example, to force download of a zip file, send the headers as

// Set headers
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$file");
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");

您无权控制用户的设置,例如由哪个应用程序打开哪种文件类型。他们必须转到设置并更改文件关联。但是,请记住,并非每个人都安装了 Excel,因此强制用户在此特定应用程序中打开 csv 文件并不是一个好主意。

我也不认为你可以禁用“打开”选项,这也是由网络浏览器的配置决定的,无论它是否会显示窗口,或者是否会直接启动关联的应用程序等等......看来你已经不在了在你的具体情况下运气好。

You have no power over users' settings such as which file type is opened by which application. They would have to go to their settings and change the file association. However, bear in mind not everyone has Excel installed, so it's not a good idea to force the user to open the csv file in this particular application.

I also don't think you can disable the Open option, this is also dictated by the web browser's configuration whether it will or will not display the window or will it launch the associated application directly etc... it seems you're out of luck in your particular case.

我相信这是操作系统级别的并且无法更改。

I believe this is OS-level and can't be changed.

一种解决方案是将 target="_blank" 添加到标记中。这样,当用户选择“打开”选项时,至少该文件将在新的(全屏或至少可调整大小)窗口中打开。

除此之外,您无法更改窗口的行为,如 ceejayoz 所说。

One half-solution is adding target="_blank" to the tag. That way, when users select the 'open' option, at least the file will be opened in a new (full-screen, or at least resizable) window.

Other than that, you can't change the behaviour of the window, as ceejayoz stated.

  • 确保在此之前没有执行任何其他输出
  • 构建 csv 字符串并将其存储在 $csvString 中
  • 在 $csv_filename 中为其指定适当的文件名
  • 标头应告诉浏览器将其加载到 Excel 中

    header("缓存控制:maxage=1");

    header("Pragma: public");

    header("内容类型:application/vnd.ms-excel");

    header("过期时间:0");

    header("缓存控制:必须重新验证,后检查=0,预检查=0");

    header("内容处置:附件;文件名=$csv_filename");

    echo $csvString;

  • Make sure you don't do any other output before this point
  • Build your csv string and store it in $csvString
  • Give it the appropriate filename in $csv_filename
  • The headers should tell the browser to load it in excel

    header("Cache-Control: maxage=1");

    header("Pragma: public");

    header("Content-Type: application/vnd.ms-excel");

    header("Expires: 0");

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

    header("content-disposition: attachment;filename=$csv_filename");

    echo $csvString;
