using header() to rewrite filename in URL for dynamic pdf
提问by user151841
I have a php script that generates a pdf report. When we go to save the pdf document, the filename that Acrobat suggests is report_pdf, since the php script is named report_pdf.php. I would like to dynamically name the pdf file, so I don't have to type the appropriate name for the report each time that I save it.
我有一个生成 pdf 报告的 php 脚本。当我们去保存pdf文档时，Acrobat建议的文件名是report_pdf，因为php脚本被命名为report_pdf.php。我想动态命名 pdf 文件，所以我不必在每次保存报告时键入适当的名称。
Asking on a news group, someone suggested this, where filename="July Report.pdf"is the intended name of the report
在新闻组上问，有人建议这个，filename="July Report.pdf"报告的预期名称在哪里
<?
header('Content-Type: application/pdf');
header('Content-disposition: filename="July Report.pdf"');
But it doesn't work. Am I doing it wrong, or will this work at all? Is this a job for mod_rewrite?
但它不起作用。我做错了吗，或者这会起作用吗？这是 mod_rewrite 的工作吗？
所以我都试过了
header('Content-disposition: inline; filename="July Report.pdf"');
and
和
header('Content-disposition: attachment; filename="July Report.pdf"');
( not at the same time ) and neither work for me. Is this a problem with my web host? For this url, here's my code:
（不是同时）而且都不适合我。这是我的网络主机的问题吗？对于这个url，这是我的代码：
<?
header('Content-disposition: inline; filename="July Report.pdf"');
// requires the R&OS pdf class
require_once('class.ezpdf.php');
require_once('class.pdf.php');
// make a new pdf object
$pdf = new Cpdf();
// select the font
$pdf->selectFont('./fonts/Helvetica');
$pdf->addText(30,400,30,'Hello World');
$pdf->stream();
?>

Try:
尝试：
header('Content-Disposition: attachment; filename="July Report.pdf"');
or
或者
header('Content-Disposition: inline; filename="July Report.pdf"');
Another option would be to use the $_SERVER['PATH_INFO']to pass your "July Report.pdf" - an example link might be:
另一种选择是使用$_SERVER['PATH_INFO']传递您的“July Report.pdf” - 示例链接可能是：
<a href="report_pdf.php/July%20Report.pdf?month=07">
That file should default to saving as "July Report.pdf" - and should behave exactly like your old php script did, just change the code that produces the link to the pdf.
该文件应默认保存为“July Report.pdf” - 并且应该与旧的 php 脚本完全一样，只需更改生成 pdf 链接的代码即可。

Should be:
应该：
header('Content-disposition: attachment;filename="July Report.pdf"');

Based on https://github.com/rospdf/pdf-php/raw/master/readme.pdf(Page 19) The stream-method accepts an array as parameter:
基于https://github.com/rospdf/pdf-php/raw/master/readme.pdf(Page 19) 流方法接受一个数组作为参数：
stream([array options])Used for output, this will set the required headers and output the pdf code. The options array can be used to set a number of things about the output:
'Content-Disposition'=>'filename'sets the filename, ...
stream([array options])用于输出，这将设置所需的标题并输出 pdf 代码。options 数组可用于设置有关输出的许多内容：
'Content-Disposition'=>'filename'设置文件名，...
This code works well for me
这段代码对我很有效
$ezOutput = $pdf->ezStream(array("Content-Disposition"=>"YourFileName.pdf"));
In my case I use ezStream()but I think stream()should give the same result.
在我的情况下，我使用ezStream()但我认为stream()应该给出相同的结果。

Did you try to remove spaces from file name using hyphens? So, I think its name must be like this; filename=July-Report.pdf
您是否尝试使用连字符从文件名中删除空格？所以，我想它的名字一定是这样的；文件名=七月报告.pdf
