Laravel 5.3 - Attach Multiple Files To Mailables - laravel

Question

How does one go about attaching multiple files to laravel 5.3 mailable?
I can attach a single file easily enough using ->attach($form->filePath) on my mailable build method. However, soon as I change the form field to array I get the following error:
basename() expects parameter 1 to be string, array given
I've searched the docs and also various search terms here on stack to no avail. Any help would be greatly appreciated.
Build Method:
public function build()
{
return $this->subject('Employment Application')
->attach($this->employment['portfolio_samples'])
->view('emails.employment_mailview');
}
Mail Call From Controller:
Mail::to(config('mail.from.address'))->send(new Employment($employment));

Answer 1

You should store your generated email as a variable, then you can just add multiple attachments like this:
public function build()
{
$email = $this->view('emails.employment_mailview')->subject('Employment Application');
// $attachments is an array with file paths of attachments
foreach ($attachments as $filePath) {
$email->attach($filePath);
}
return $email;
}
In this case your $attachments variable should be an array with paths to files:
$attachments = [
// first attachment
'/path/to/file1',
// second attachment
'/path/to/file2',
...
];
Also you can attach files not only by file paths, but with MIME type and desired filename, see documentation about second case of use for the `attachment` method: https://laravel.com/docs/master/mail#attachments
For example, your $attachments array can be something like this:
$attachments = [
// first attachment
'path/to/file1' => [
'as' => 'file1.pdf',
'mime' => 'application/pdf',
],
// second attachment
'path/to/file12' => [
'as' => 'file2.pdf',
'mime' => 'application/pdf',
],
...
];
After you can attach files from this array:
// $attachments is an array with file paths of attachments
foreach ($attachments as $filePath => $fileParameters) {
$email->attach($filePath, $fileParameters);
}

Best solution work for me
$email = $this->from($from)->subject("Employment Application")
->view('emails.employment_mailview');
foreach ($files as $file) {
$path = '/path/to/'.$file->file;
$attachments->push($path);
}
$attachments = collect([]);
foreach ($attachments as $filePath) {
$email->attach($filePath);
}
return $email;

This worked for me, maybe it will work for more people.
As I am getting the files via $request this was the solution works for me.
obs: sorry I'm using translate. From Portuguese(Brazil) to English.
thanks #AlexanderReznikov, it helped me a lot.
class SendMailextends Mailable
{
protected $inputs;
protected $files;
public function __construct(array $inputs, array $files)
{
$this->inputs = $inputs;
$this->files = $files;
}
public function build()
{
if (isset($this->files)){
$email = $this->from('you#mail')->view('email.email-contact')->subject('Email teste mulptiple files');
for ($indice = 0; $indice < count($this->files['files']); $indice++) {
$files = $this->files[$indice];
$pathName = $files->getPathname();
$attachments = $pathName;
$fileName = $files->getClientOriginalName();
$email->attach($attachments,['as' => "$fileName"]);
}
return $email;
}else{
// file empty, send email
return $this->from('you#mail','name')->subject('Email teste mulptiple files')
->view('email.email-contact');
}
}
}
