Something very simple, to have a minimal notion of what you really should do, is this:
<?php
// index.php
// apresentar os respectivos links
print "<a href=\"download/{$item['chave']}\" target=\"_blank\">{$item['nome']}</a>";
print "<a href=\"download/{$item['chave']}\" target=\"_blank\">{$item['nome']}</a>";
// verificar se o link foi clicado
$a = isset($_GET['a']) ? $_GET['a'] : null; // a=download
$f = isset($_GET['f']) ? $_GET['f'] : null; // f=chave_no_banco
if(isset($a) && isset($f)){
/* algo melhor elaborado aqui,
para verificar os detalhes da chave e retornar
dados correspondentes do banco antes de iniciar a transferencia,
ou algo semelhante
*/
print "A transferir: <br/>";
print "<strong>ficheiro: </strong>{$f}<br>";
sleep(1);
include_once 'download.php';
}
For htaccess you could add this:
RewriteRule ^download/([A-Za-z0-9]+)$ index.php?a=download&f=$1
To download the file in question:
<?php
$name= $_GET['f'];
$randNumber = date('d-m-Y');
header('Content-Description: File Transfer');
header('Content-Type: application/force-download');
header("Content-Disposition: attachment; filename=\"" . basename($randNumber.$name) . "\";");
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($name));
ob_clean();
flush();
readfile("_directorio_do_arquivo_no_servidor/".$name);
exit;
?>
NOTE: Although without something functional, I do not say for now that it is recommended, there are procedures that you must still implement and several modifications to make, so that it is implemented successfully. See also apache documentation.
