Multiple PDFdownloads

Question

I have a local DB table in which many PDF links are saved around 15000. I want to download all that PDF on one click but my problem is its opening PDF not downloading. I was trying this method.

items = Array.from(document.getElementsByTagName("a"));
items.forEach(function(item) {
    link = item.href;
    if (link.substr(link.length - 4) == ".pdf") {
        filename = link.replace(/^.*[\\\/]/, '');
        item.download = filename;
        item.click();
    }
});

Do tag it properly, you have coded it up in JS it pops up under the php tag. — damagedCoda, Feb 27 '19 at 05:23

You can not download all files using only 1 click. Instead of You can use ZIP Archive Class in PHP.

Make one zip file of all available pdf and download it.

$files = array('pdf1.pdf','pdf2.pdf');
$zipname = 'file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);

  foreach ($files as $file) {
    $zip->addFile($file);
  }

  $zip->close();

And Headers Like

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);

Thanks for your reply, this code works for me with zip archive

$files = array('pdflink','pdflink');
$zip = new ZipArchive();
$tmp_file = tempnam('.','');
$zip->open($tmp_file, ZipArchive::CREATE);

foreach($files as $file){
    $download_file = file_get_contents($file);
    $zip->addFromString(basename($file),$download_file);
}   
$zip->close();
header('Content-disposition: attachment; filename=file.zip');
header('Content-type: application/zip');
readfile($tmp_file);

?>
