Pass variable from controller to notification in Laravel - laravel

Question

I am finding it hard to understand the examples from the docs to the scenario I am having. In my project I have an application form which filled up by the user then admin will update that form once the application is approved, canceled etc.
Now I want to notify the user that her/his application has been approved, canceled etc.
in my controller:
public function update(Request $request, $id)
{
$this->validate($request, [
'status' => 'required'
]);
$requestData = $request->all();
$loanapplication = LoanApplication::findOrFail($id);
$loanapplication->update([
"status" => $request->status,
"admin_notes" => $request->admin_notes,
"date_approval" => $request->date_approved
]);
if($request->notifyBorrower = 'on') {
$user_id = $loanapplication->user_id;
$status = $request->status;
$this->notify(new AdminResponseToApplication($user_id));
}
return redirect()->back()->with('flash_message', 'LoanApplication updated!');
}
In my AdminResponseToApplication.php I like to achieve this
<?php
namespace App\Notifications;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
class AdminResponseToApplication extends Notification implements ShouldQueue
{
use Queueable;
public function __construct()
{
//
}
public function via($notifiable)
{
return ['mail','database'];
}
public function toMail($notifiable)
{
return (new MailMessage)
->line(.$user->nameHere. 'your application has been '.$statusHere.'.')
->action('check it out', url('/'))
->subject('Regarding with your loan application')
->line('This is system generated. Do not reply here.');
}
public function toDatabase($notifiable)
{
return [
'user_id' => $user->nameHere,
'status' => $statusHere,
'title' => .$user->nameHere. 'your application has been '.$statusHere.'.',
'url' => '/'
];
}
}
How can I achieve that? Thank you in advance!

Answer 1

Get user object and call function notify() on it. $this->notify() will not work because $this is not an instance of User class.
$user = User::find($user_id);
$user in the $user->notify(new AdminResponseToApplication($data)) function is available in notification class as $notifiable.
You can get any value of that object using $notifiable->name etc.
Remember:
AdminResponseToApplication is a class and you can do anything with it that a php class can.
So you can pass as many variables as you want to AdminResponseToApplication class in constructor and do what you want.
$user->notify(new AdminResponseToApplication($data))
As shown above I am sending a $data object to the class which is available in the constructor.
In the class
class AdminResponseToApplication extends notification implements ShouldQueue{
use Queueable;
public $myData;
public function __construct($data)
{
$this->myData = $data; //now you have a $data copied to $this->myData which
// you can call it using $this->myData in any function of this class.
}
}
