Laravel send multiple attachments to Mailables

Rather than returning the direct mail call in the build method of a mailable you can assign it to a variable then add multiple attach calls before returning.

Here’s an example:

public function build()
{
    //setup the mail
    $mail = $this->subject('The subject', ['content' => $content])->markdown('mail.sendreply');

    //loop through attachments and attach to $mail
    $att = Attachment::where('sendEmail', 'Yes')->get();
    foreach($att as $file) {
        //attach the file
        $mail->attach($file->filePath);
    }

    //return and execute sending the mailable
    return $mail;
}
