Download multiple uploaded files in Laravel - php

Question

I have a form input which can upload multiple files. So all the files paths are saved in the database as an array of strings . Below is my controller to download the files. I wanted to know how I can go about presenting each file to be downloaded in blade view. So I could download a single file at a time. My controller below. It works only when downloading a single file. I get this error Invalid argument supplied for foreach().
public function download($id) {
$deal = Deal::findorFail($id);
$files = $deal->uploads;
foreach ($files as $file) {
return Storage::download($file);
}
}

Answer 1

public function download($id) {
$deal = Deal::findorFail($id);
$files = $deal->uploads;
foreach ($files as $file) {
return Storage::download($file);

}
}
when you return first file, it breaks foreach loop. So you have to return all files together. And only way to achieve this, is creating a zip file that contains all files..
For this purpose you may use chumper/zipper package
$zipper = Zipper::make(public_path('/documents/deals.zip'));
foreach ($files as $file) {
$zipper->add(public_path($file)); // update it by your path
}
$zipper->close();
return response()
->download(
public_path('/temporary_files/' . "deals.zip"),
"deals.zip",
["Content-Type" => "application/zip"]
);
update
Add accessor to Deal model to get files as array
Deal Model
php artisan getUploadsAttribute($attribute){
return explode(",",$attributes);
}
