I have a form in which users can select files and create a zip archive of the selected. Everything is working as expected except for the fact that the zip file is created in the wp-admin folder. Instead, I would like for it to be housed in a temp folder and deleted immediately after it has finished downloading.
Here is the PHP code for the creation of the zip archive:
// Creates zip file
function bcg_zip_download() {
$files = $_POST['checked'];
$zip = new ZipArchive();
$zip_name = time().".zip"; // Zip name
$zip->open($zip_name, ZipArchive::CREATE);
$full = wp_upload_dir();
$base = $full['baseurl'] .'/';
if (is_array($files)){
foreach ($files as $file) {
$path = $file;
if(file_exists($_SERVER['DOCUMENT_ROOT'].'/bcg/wp-content/uploads/'.$path)){
$zip->addFromString(basename($base . $path), file_get_contents($base . $path));
}
else {
echo"file does not exist";
}
}
}
$zip_file_path = $zip_name;
$zip->close();
echo admin_url(). '/' . $zip_name;
unlink($zip);
wp_die();
}
add_action( 'wp_ajax_nopriv_download_folder', 'bcg_zip_download' );
add_action( 'wp_ajax_download_folder', 'bcg_zip_download' );
