Header Question

Copy linkTweet thisAlerts:
Jan 05.2007

Using headers to force a download with “Content-type: application/force-download”, and providing the web browser with the filename by using “Content-Disposition: attachment; filename=$filename”, is there some way to tell the browser what the file’s size is? That way, when downloading a file, I could actually see the percent of it that’s been completed, instead of guessing.

@MrCoderJan 05.2007 — [code=php]
header("Content-Length: ".filesize("/path/to/my/file/filename.pdf"));
[/code]

Or if you are not using a file, for example if you are generating a thumbnail of an image on the fly.

[code=php]
ob_start();
// ECHO THE DATA HERE
echo file_get_contents("/path/to/my/file/filename.pdf");
header("Content-Length: ".ob_get_length());
ob_end_clean();
[/code]

The above should work ok, just typed from memory..

@AmazingAntauthorJan 05.2007 — Ok, so the point is to use this general idea:
[code=php]
header("Content-Length: ".$filesize);
[/code]

Thanks to the both of you!

Wouldnt that return an array on anything that was not a URL or MIME file?

@NightShift58Jan 06.2007 — You caught me out there in left field... I was working on another (image) script and I have to assume I got distracted in the midst of Copy&Paste.

In fact, I think it returns an array not matter what and that doesn't even contain the size, as such.

Success!
