Question

i got this code in attaching a pdf file to my site in order for the viewers to download such pdf file..

$fullPath = “../public/pdffiles/FolioPlusUserGuide(v3.0).pdf”;

    if ($fd = fopen ($fullPath, "r")) {

        $fsize = filesize($fullPath);
        $path_parts = pathinfo($fullPath);
        $ext = strtolower($path_parts["extension"]);

        header("Content-type: application/pdf");
        header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\"");            
        header("Content-length: $fsize");
        header("Cache-control: private");

        while(!feof($fd)) {
            $buffer = fread($fd, 2048);
            echo $buffer;
        }
    }

    fclose ($fd);
    exit;

html code:

baseUrl().’/DownloadPdf’?>”>DOWNLOAD BROCHURE

this code only accommodates 1 file path, I have more pdf files with different filename and different buttons for each to handle the download event. how can i achieve this?..thanks ahead!..=)

Answer 1

You can pass PDF file name via HTTP request, like this:

DownloadPDF.php?filename=test1.pdf

Then in your DownloadPDF file have something like this:

$pdfdir = "/pdffiles/folder/location/here";
$pdffilename = $_GET['filename'];
$fullPath = $pdfdir.$pdffilename;

if ($fd = fopen ($fullPath, "r")) {

        $fsize = filesize($fullPath);
        $path_parts = pathinfo($fullPath);
        $ext = strtolower($path_parts["extension"]);

        header("Content-type: application/pdf");
        header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\"");            
        header("Content-length: $fsize");
        header("Cache-control: private");

        while(!feof($fd)) {
            $buffer = fread($fd, 2048);
            echo $buffer;
        }
    }

    fclose ($fd);
    exit;

Now your code is dynamic and you can download any PDF with links like this:

<a href=downloadpdf.php?filename=something.pdf>Something</a>
<a href=downloadpdf.php?filename=something2.pdf>Something2</a>

etc.
