Someone knows how to add headers to emails sent through Laravel Notification System?
I am not talking about Mailable classes where I can set header through the withSwiftMessage() method!
I also would like to keep using the MailMessage once I have a lot of emails built using the line, greetings methods!
Any one has any clue?
There is my code in case somebody needs to see anything!
<?php
namespace PumpMyLead\Notifications\Tenants\Auth;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
class AccountActivation 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)
->subject('My email subject')
->greeting('Just a greeting')
->line('Line 1')
->line('Line 2')
->action('CTA wanted', 'http://www.pumpmylead.com')
->line('Byebye');
}
}
Thanks in advance!
Actually I've found 2 ways to append headers.
When the notification is sent via mail channel an Illuminate\Mail\Events\MessageSending event is fired.
Append a listener to it. In handle() you will get the Swift_Message object.
Or in the AppServiceProvider's register() method override the MailChannel with your own and append the header in the send() method.
$this->app->bind(
\Illuminate\Notifications\Channels\MailChannel::class,
MyMailChannel::class
);
In ./app/Notifications/myNotification.php, add this code in your __construct() function:
$this->callbacks[]=( function($message){
$message->getHeaders()->addTextHeader('x-mailgun-native-send', 'true');
});
Replace the "x-mailgun-native-send" with any header you wish to add, and 'true' with the desired value.
Here's a modern 2022 alternative if the above doesn't work, tested in Laravel 8.
using withSwiftMessage()
public function toMail($notifiable)
{
return (new MailMessage)
->subject($subject)
->greeting($greeting)
->line($line1)
->line($line2)
->withSwiftMessage(function($message) use ($value1, $value2) {
$message->getHeaders()->addTextHeader('X-MJ-CustomID', json_encode([
'key1' => $value1,
'key2' => $value2,
]));
})
}
