How download 2 files from same app ? When I download the first then the app stop.

Hi all.
I got a form button that has to download 2 files. One is a pdf as output of from Pdf Report and one is PNG.
Until today I did only the pdf and it was working.
Today I added a png file and no way to download them both in the same time.
If I reverse the code it download only the png.

How can I fix this issue ??



$sql_id ="SELECT id_ticket FROM ticket WHERE id_ticket_progr = " . {id_ticket_progr};

sc_lookup(rs_ID, $sql_id);

if (isset({rs_ID[0][0]})) // Row found

//echo "VARIABILE NR TICKET BUTTON " . [glo_id_ticket] ;

sc_redir(pdfreport_ticket , [glo_id_ticket] , ‘_parent’);

//PNG that has to be download togheter the pdf just in case of IF … = Y

if([glo_covid19] == “Y”)

$path = realpath(dirname(__FILE__) . '/..');
//$file_name = "Doc_Covid19.png";
$file_name ="grp__NM__img__NM__Doc_Covid19.png";
$file_path_name = $path . "/_lib/img/" . $file_name;
$new_filename = "Covid_19_Eos.png";

if (file_exists($file_path_name)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
//header('Content-Disposition: attachment; filename='.basename($file_path_name));
