pdf 文件下载的正确 PHP 标头 [英] correct PHP headers for pdf file download

问题描述

当用户单击链接时，我真的很难让我的应用程序打开 pdf.

到目前为止，锚标记重定向到发送以下标头的页面:

$filename='./pdf/jobs/pdffile.pdf;$url_download = BASE_URL .相对路径.$文件名;标头(内容类型:应用程序/pdf")；标头(内容处置:内联；文件名=$文件名")；读取文件(下载的.pdf")；

这似乎不起作用，过去有人成功解决过这个问题吗?

解决方案

Example 2 on w3schools 显示您正在努力实现的目标.

<块引用>

还要记住，

<块引用>

需要注意的是 header() 必须在任何发送实际输出(在 PHP 4 及更高版本中，您可以使用 output缓冲来解决这个问题)

I'm really struggling to get my application to open a pdf when the user clicks on a link.

So far the anchor tag redirects to a page which sends headers that are:

$filename='./pdf/jobs/pdffile.pdf;

$url_download = BASE_URL . RELATIVE_PATH . $filename;

header("Content-type:application/pdf");
header("Content-Disposition:inline;filename='$filename");
readfile("downloaded.pdf");

this doesn't seem to work, has anybody successfully sorted this problem in the past?

解决方案

Example 2 on w3schools shows what you are trying to achieve.

<?php
header("Content-type:application/pdf");

// It will be called downloaded.pdf
header("Content-Disposition:attachment;filename='downloaded.pdf'");

// The PDF source is in original.pdf
readfile("original.pdf");
?>

Also remember that,

It is important to notice that header() must be called before any actual output is sent (In PHP 4 and later, you can use output buffering to solve this problem)
