Sending Emails using Laravel event and listeners

steps-to-follow.text

Step 1. Creating event and listener
There are two ways to creating event and listeners
First way:
1. Open "App\Providers\EventServiceProvider.php"
2. Inside the "protected $listen" array, add the following. Change the event name and listener to your deside name.

        'App\Events\EmployerWelcomeMail' => [
            'App\Listeners\SendEmployerWelcomeMail',
        ],

3. Run "php artisan event:generate"; 
    NB: This will generate the event and it listener under the directoery "App\Events\EmployerWelcomeMail.php" and App\Listeners\SendEmployerWelcomeMail.php" respectively.


Second way:
1. Run php artisan make:event EmployerWelcomeMail
2. Run php artisan make:listener SendEmployerWelcomeMail --event="EmployerWelcomeMail"
3. Repeat step 1 and 2 in the first way above.


Step 2: Making changes in our event:

1. Open "App\Events\EmployerWelcomeMail.php" and do the following:
    a. add "public $employer". This makes the variable public and accessible in the mail markdown.
    b. Add the variable and initialize it in the constructor as below
         public function __construct($employer)
          {
             $this->employer = $employer;
           }

Step 3: Creating our mailables
1. Create a mailable class with it markdown by running "  php artisan make:mail SendingEmployerWelcomeMail --markdown=emails.sendingEmployerWelcomeMail "
    NB: This will create a mailable class located in "App\Mail\SendingEmployerWelcomeMail.php" and the view at "resources\views\emails\sendingEmployerWelcomeMail.blade.php"

2. Open "App\Mail\SendingEmployerWelcomeMail.php" and do the following:
    a. add "public $employer". This makes the variable public and accessible in the mail markdown.
    b. Add the variable and initialize it in the constructor as below
         public function __construct($employer)
          {
             $this->employer = $employer;
           }
    c. You can add subject of your email inside the build function as below
          public function build()
         {
          return $this->subject('Congratulations!')
                    ->markdown('emails.sendingEmployerWelcomeMail');
          }
  
Step 4: Making changes to our listener class
1. Call your Mailable class and send in  the handle or  "App\Listeners\SendEmployerWelcomeMail.php"
      \Mail::to($event->user->email)->send(new SendingEmployerWelcomeMail($event->user));
     NB: Import the mailable class "use App\Mail\SendingEmployerWelcomeMail;"
     
     
Step 5: Calling the event
 The event can now be called at where you want to send an email after an action as below.
 
 "event(new EmployerWelcomeMail( $employer));"
 NB: Import the event on top as "use App\Events\EmployerWelcomeMail;"
 
 
 Final tips:
 You can change your mailable markdown to your liking.
