I once made a similar script, what you have to do is set some headers and echo the data from database.

An example of that could be, assuming that the data is in $row['filedata'], the following

Now you have to know what file to download first, and for that we can use a GET or POST parameter

 1 || $result_check < 1){ //If more then 1 result die
    die('inavlid ID');
}
$row = mysqli_fetch_assoc($result);
//and here the above mentioned lines
?>

The easiest way to add a download button to the page would be by using the window.open() function in JavaScript like so:

echo $row['Ime']."Download
";

This will open a new window which will download the file

The total would look something like this For download.php:

 1 || $result_check < 1){ //If more then 1 result die
    die('inavlid ID');
}
$row = mysqli_fetch_assoc($result);
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=".$row['Ime']);
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");
echo $row['filedata'];
?>

and for index.php

 0){
    while($row = mysqli_fetch_assoc($result)){
        echo $row['Ime']."Download
";
    }
}
?>
