Laravel 5.3 How to show Username in Notifications Email - laravel

Question

I am trying to add the user's first name in the notification emails. At the moment, Laravel notification emails starts like:
Hello,
And I want to change it to:
Hello Donald,
Right now, I have a set-up like this. This example is for a Password Reset Notification email:
User Model:
public function sendPasswordResetNotification($token)
{
$this->notify(new PasswordReset($token));
}
App\Notifications\PasswordReset:
class PasswordReset extends Notification
{
use Queueable;
/**
* Create a new notification instance.
*
* #return void
*/
public function __construct()
{
//
}
/**
* Get the notification's delivery channels.
*
* #param mixed $notifiable
* #return array
*/
public function via($notifiable)
{
return ['mail'];
}
/**
* Get the mail representation of the notification.
*
* #param mixed $notifiable
* #return \Illuminate\Notifications\Messages\MailMessage
*/
public function toMail($notifiable)
{
return (new MailMessage)
->line('The introduction to the notification.')
->action('Notification Action', 'https://laravel.com')
->line('Thank you for using our application!');
}
/**
* Get the array representation of the notification.
*
* #param mixed $notifiable
* #return array
*/
public function toArray($notifiable)
{
return [
//
];
}
}
Is the User Model automatically binded with the Notification Class? How can I add the username in the view?

Answer 1

The $notifiable variable passed to toMail() is User model.
Call to needed User model attribute, easy:
public function toMail($notifiable)
{
return (new MailMessage)
->greeting('Hello '. $notifiable->username)
->line('The introduction to the notification.')
->action('Notification Action', 'https://laravel.com')
->line('Thank you for using our application!');
}

Answer 2

Try this:
User Model:
public function sendPasswordResetNotification($token) {
return $this->notify(new PasswordReset($token, $this->username));
}
App\Notifications\PasswordReset:
class PasswordReset extends Notification
{
use Queueable;
public $username;
public function __construct($token, $username)
{
$this->username = $username;
}
public function via($notifiable)
{
return ['mail'];
}
public function toMail($notifiable)
{
return (new MailMessage)
->greeting('Hello '.$this->username.',')
->line('The introduction to the notification.')
->action('Notification Action', 'https://laravel.com')
->line('Thank you for using our application!');
}
}

Answer 3

You have to edit toMail function in App\Notifications\PasswordReset to set greeting as you want.
public function toMail($notifiable) {
return (new MailMessage)
->greeting('Hello '. $this->username)
->line('The introduction to the notification.')
->action('Notification Action', 'https://laravel.com')
->line('Thank you for using our application!');
}
Update
To set $username, have to define a variable & setter method in App\Notifications\PasswordReset.
protected $username = null;
public function setName($name) {
$this->username = $name;
}
When you initialize App\Notifications\PasswordReset, you can set the name.
In User model update the function as below.
public function sendPasswordResetNotification($token) {
$resetNotification = new ResetPasswordNotification($token);
$resetNotification->setName($this->name);
$this->notify($resetNotification);
}
