Write common methods in laravel 5.2

Question

To develop a project where I am creating some methods which are common in all the controllers.

Before this I have used codeigniter and there I wrote MY_Controller class in core directory and then I extended the controller in all the controllers in controller directory.

Same I want to do inside Laravel . But I am confused that where should I write the common methods like send_email , validate_captcha , ajax_file_upload and other common methods which remains same across whole application.

So please suggest me a good way to define such a class or middleware.. What should one do to create that?

Answer 1

OK. Let me suggest some stuffs

1. Need to write methods which is apply to all Controllers. You
   can/should modify App\\Http\\Controllers\\Controller.php . Because all Controllers in Laravel extend it
2. Need to write class that available across whole application. It is never easier

Step 1 : Write any class you want in app folder. And follow psr-4 convention

Step 2 : Register to Laravel application In App\\Providers\\AppServiceProvider . In register() method. Add

$this->app->bind('bindname', function ($app) {
    return new \App\YourClass;
    // If you want to inject other class to YourClass contructor
    // return new \App\YourClass($app->make('otherbindname'));
});

Step 3 : Use it. There are several ways to access YourClass in your whole application:

app()->make('bindname');

app('bindname');

app()['bindname'];

\App::make('bindname');

//etc
