Override sendSwiftMessage() Laravel Swiftmailer with custom

Question

I am using Laravel 4.2

The answer given by user3158900 is for Laravel 5.* Any one can help me with version 4.2 ?

I would like to override sendSwiftMessage() protected function with my own function.

sendSwiftMessage() is located in

"vendor/laravel/framework/src/Illuminate/Mail/Mailer.php"

I created a

Lib/Mailer/CustomMailer.php

and Set the folder Lib to autoload in composer (PSR4). I can now call/load my function in my controllers by writing:

new Lib\Mailer\CustomMailer;

This is how my file looks like:

<?php namespace Lib\Mailer;

class CustomMailer extends \Illuminate\Mail\Mailer {

    /**
     * Send a Swift Message instance.
     *
     * @param  \Swift_Message  $message
     * @return void
     */
    protected function sendSwiftMessage($message)
    {
        if (strpos($message->toString(), '[email protected]') == true) {
            Log::info('Not sending mail to [email protected]');
        }
        else
        {
            if ($this->events)
            {
                $this->events->fire('mailer.sending', array($message));
            }

            if ( ! $this->pretending)
            {
                $this->swift->send($message, $this->failedRecipients);
            }
            elseif (isset($this->logger))
            {
                $this->logMessage($message);
            }
        }
    }

}

However, this sendSwiftMessage() function is not used when I send an email with Swiftmailer in my controller by doing EXAMPLE:

Mail::send(xxxx);

My question: How can I make Swiftmailer/Laravel use my custom sendSwiftMessage() function when I send a message if I don't want to modify all my Controllers that currently use the Mail::send() code

Think I got this figured out, however I am getting an error but I think that's on you because your custom class is using a property that doesn't exist so here's the solution anyway.

In AppServiceProvider.php in the boot() method, I've added the following:

$this->app->singleton('customMailer', function($app) {
    return new CustomMailer(
        $app['view'], $app['swift.mailer'], $app['events']
    );
});

In app/Lib/Mailer folder, I've added another class for the facade.

namespace App\Lib\Mailer;

use Illuminate\Support\Facades\Facade;

class Mail extends Facade
{
    /**
     * Get the registered name of the component.
     *
     * @return string
     */
    protected static function getFacadeAccessor()
    {
        return 'customMailer';
    }
}

In config/app.php, I've replaced the Mail alias with the following...

'Mail' => App\Lib\Mailer\Mail::class,

And that should be all you need to do.

One other thing, I just noticed you are missing in your namespace the App which explains why you had to add the Lib folder to the autoloader. If you namespace it correctly to keep it inline with PSR-4 by adding the App\ onto the beginning, then you don't need to add anything to your composer.json file to get additional classes loaded.

Oh you are using Laravel 4. I'm sorry, this code may not work.
