Open PDF-File in browser without href or embed

Hendrik Lampert · Feb 24, 2004

Hi,

a simple html page consists of a select box (1,2,3,4,5....). After selectin
one of the numbers, the corresponding PDF File should appear in the browser.
Doing it with "<embed src=... width=... height=...> fixes the size of the
PDF frame. Is there any way to get a dynamic output size, like calling the
PDF via href?
Any other solution?

Many thanks.
Regards,
Hendrik

Here a piece of PHP:

<?php
// when form submitted, redirect to PDF file
if($file=="dick.pdf" || $file=="andrea.pdf" || $file=="lewis.pdf")
{
header("Location: $file");
exit();
}

// and else just display the thing
?>
<html>
<head>

<title>Download a PDF file</title>

</head>
<body>

<form action="thisfile.php" method="get">
<fieldset>
<legend>Please select a PDF file to download</legend>

<select name="file" size="1">
<option value="dick.pdf">Dick</option>
<option value="andrea.pdf">Andrea</option>
<option value="lewis.pdf">Lewis</option>
</select>
<input type="submit" value="Download!">

</form>

</body>
</html>

You are right. Damn, I have been doing it wrongly for so long now then.
Is the Content-location header a good solution then, to redirect through
a relative URI?

I have RFC2616 lying beside the bed, never got to it reading the thing.

The mistake i made was, to embed the pdf into a html table. If you do so,
the percantage parameters for height and width in <embed ....> won't work.
Outside ab table everything works fine.

If you want to indicate the URI of a variant relative to the
Request-URI: yes.

(To state the obvious: You can use "Location" and simply build
the absoluteURI; +/-:

"http://" . $_SERVER["HTTP_HOST"] . dirname($_SERVER["PHP_SELF"]) . "/$file";

)

Nah, Kris... don't worry - you're alright. PHP intercepts the header and
replaces it with one that makes more sense.

Don't count on it. A 'note' can be found here:
http://www.php.net/manual/en/function.header.php
["Note: HTTP/1.1 requires an absolute URI as argument to Location: including
" the scheme, hostname and absolute path, but some clients accept relative
URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and
dirname() to make an absolute URI from a relative one yourself"]

On my Apache server (2.0.40) with PHP (4.3.4) nothing of the sort happens.

Well, over here, it seems to be intercepted and replaced with the
Content-Location header (which does accept relative URIs).

It's very nice if 'somewhere' down the line 'something' is trying to correct
your mistakes, I guess. The Content-Location header is there, but after the
"replacement" I still see: "Location: tables".
