How to send Data from Laravel Controller to Mailable Class

Question

I have created Mailable Class in Laravel 5.3 which calls the view. However, I need to pass some variables from my Controller to the Mailable Class and then use these values inside the View. This is my set-up:

Controller:

$mailData = array(
                   'userId'     => $result['user_id'],
                   'action'     => $result['user_action'],
                   'object'     => $result['user_object'],
                  );
Mail::send(new Notification($mailData));

Mailable:

class Notification extends Mailable
{
    use Queueable, SerializesModels;

    protected $mailData;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct($mailData)
    {
        $this->$mailData = $mailData;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        // Array for Blade
        $input = array(
                          'action'     => $mailData['action'],
                          'object'     => $mailData['object'],
                      );

        return $this->view('emails.notification')
                    ->with([
                        'inputs' => $this->input,
                      ]);
    }
}

The above gives me the error:

ErrorException in Notification.php line 25:
Array to string conversion

Referring to the construct line in Mailable Class:

$this->$mailData = $mailData;

What have I got wrong here? How do I correctly pass array values from Controller to Mailable and then use with to pass them on to the View?

Answer 1

Try this:

public $mailData;

public function __construct($mailData)
{
    $this->mailData = $mailData;
}

public function build()
{
    // Array for Blade
    $input = array(
                      'action'     => $this->mailData['action'],
                      'object'     => $this->mailData['object'],
                  );

    return $this->view('emails.notification')
                ->with([
                    'inputs' => $input,
                  ]);
}
