Can we send different emails to user and admin at once using single event in laravel? - laravel

Question

I am creating a leave request application for employee in an organization where user can create a leave request and admin(s) can approve/reject the request. The user and admin(s) should receive mail each time after making a leave request and after approval too. I am using event listener to send the mail and could send the mail using separate events and listeners(4 events:
making leave request to admin,
making leave request to user,
after accepting/rejecting the request to admin and
accepting/rejecting the request to user
and likewise 4 listeners too)
but it would be better if I could reduce the number of events and listeners in this case since the user mail and email template only are different.
I studied about event subscribers which subscribe to multiple events from within the subscriber class itself which is not what I want.
Is it possible to send multiple emails to multiple user/admin using less number of events/listeners?
I am using laravel 8
Code:
controller is:
public function store(Request $request)
{
DB::beginTransaction();
try{
$request->validate(
[
'leave_type' => 'in:halfday,fullday',
'start_date' => 'required',
'end_date' => 'required',
'assignee' => 'required',
]
);
$datetime1 = new \DateTime($request->start_date);
$datetime2 = new \DateTime($request->end_date);
$interval = $datetime1->diff($datetime2);
$days = $interval->format('%a');//total requested days
$leave_request= new LeaveRequest();
$leave_request->requested_by = auth()->user()->id;
$leave_request->leave_type_id = $request->leave_type_id ;
$leave_request->leave_type = $request->leave_type;
$leave_request->start_date = $request->start_date;
$leave_request->end_date = $request->end_date;
$leave_request->total_days = $days+1;
$leave_request->assignee = $request->assignee;
$leave_request->reviewer = $request->reviewer;
if($leave_request->save()){
$user = User::where('id', auth()->user()->id)->first();
$assignee = User::where('id',$request->assignee)->first();
$assignee->locale = App::currentLocale();
$assignee->requested_by = $user->name;
event(new SendLeaveRequestToAdminEvent($assignee));//send mail to admin asignee
if($request->reviewer !=null){
$reviewer = User::where('id',$request->reviewer)->first();
$reviewer->locale = App::currentLocale();
$reviewer->requested_by = $user->name;
event(new SendLeaveRequestToAdminEvent($reviewer));//send mail to admin reviewer(optional)
}
$user->locale = App::currentLocale();
event(new SendLeaveRequestToUserEvent($user));//send mail to user
DB::commit();
return response()->json([
'message'=> 'Leave requested successfully',
'status_code' => 200,
]);
}
else{
DB::rollback();
return response()->json([
'status_code' => '204',
'message' => 'Leave request failed',
]);
}
} catch (Exception $error) {
DB::rollback();
return response()->json([
'message' => 'Leave request failed',
'error' => $error
]);
}
}
first event to mail to admin(s) i.e; assignee and reviewer after sending leave request is
<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
use App\Models\User;
class SendLeaveRequestToAdminEvent
{
use Dispatchable, InteractsWithSockets, SerializesModels;
public $admin;
/**
* Create a new event instance.
*
* #return void
*/
public function __construct(User $admin)
{
$this->admin = $admin;
}
/**
* Get the channels the event should broadcast on.
*
* #return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new PrivateChannel('channel-name');
}
}
second event to mail to user after sending leave request is
<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
use App\Models\User;
class SendLeaveRequestToUserEvent
{
use Dispatchable, InteractsWithSockets, SerializesModels;
public $user;
/**
* Create a new event instance.
*
* #return void
*/
public function __construct(User $user)
{
$this->user = $user;
}
/**
* Get the channels the event should broadcast on.
*
* #return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new PrivateChannel('channel-name');
}
}
first listener to admin(s):
<?php
namespace App\Listeners;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Support\Facades\Mail;
use App\Mail\LeaveRequestAdmin;
use App\Events\SendLeaveRequestToAdminEvent;
class SendLeaveRequestToAdminListener
{
/**
* Create the event listener.
*
* #return void
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* #param SendLeaveRequestToAdminEvent $event
* #return void
*/
public function handle(SendLeaveRequestToAdminEvent $event)
{
$email = $event->admin->email;
Mail::to($email)->locale($event->admin->locale)->send(new LeaveRequestAdmin($event->admin));
}
}
second listener to user:
<?php
namespace App\Listeners;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Support\Facades\Mail;
use App\Mail\LeaveRequestUser;
use App\Events\SendLeaveRequestToUserEvent;
class SendLeaveRequestToUserListener
{
/**
* Create the event listener.
*
* #return void
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* #param SendLeaveRequestToUserEvent $event
* #return void
*/
public function handle(SendLeaveRequestToUserEvent $event)
{
$email = $event->user->email;
Mail::to($email)->locale($event->user->locale)->send(new LeaveRequestUser($event->user));
}
}
mail to admin:
<?php
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\URL;
class LeaveRequestAdmin extends Mailable
{
use Queueable, SerializesModels;
public $admin;
/**
* Create a new message instance.
*
* #return void
*/
public function __construct($admin)
{
$this->admin = $admin;
}
/**
* Build the message.
*
* #return $this
*/
public function build()
{
return $this->markdown('email.leaverequestadmin', [
'url' => URL::to('/home'),
'admin' => $this->admin,
])->subject('Incoming Leave Request');
}
}
mail to user:
<?php
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\URL;
class LeaveRequestUser extends Mailable
{
use Queueable, SerializesModels;
public $user;
/**
* Create a new message instance.
*
* #return void
*/
public function __construct($user)
{
$this->user = $user;
}
/**
* Build the message.
*
* #return $this
*/
public function build()
{
return $this->markdown('email.leaverequestuser', [
'url' => URL::to('/home'),
'user' => $this->user,
])->subject('Leave Request Received');
}
}
the above code is used after leave request is created which have two separate events/listeners/mail/ blade templates. Like wise I have similar another two events/listeners/mail/ blade templates each which are used after the leave request is accepted/rejected.
