Laravel as a controller to call another controller

Laravel Controllers: Learn how to call one controller from another with a step-by-step example.

Calling a Controller From Another Controller in Laravel

Laravel provides an effective way of calling a controller from within another controller, allowing developers to easily create modular, maintainable code. This technique is particularly useful for creating a RESTful API, but can also be used in other scenarios. In this tutorial, we'll explore how to call a controller from another controller in Laravel. We'll also look at some best practices for structuring your code and keeping things organized.

Using The Controller Method

The simplest way to call a controller from another controller is to use the controller method. This method allows you to pass the name of the controller class as a parameter, and the method will return an instance of the controller. This instance can then be used to call methods within the controller. For example, if we have a controller named UserController that contains a method show, we can call it from another controller like this:

public function index()
{
    $userController = $this->controller('UserController');
    $userController->show();
}

The controller method can also be used to pass parameters to the controller. To do this, simply pass an array of parameters as the second argument to the controller method. For example, if the UserController has a method show that takes an $id parameter, we can pass it like this:

public function index()
{
    $userController = $this->controller('UserController', ['id' => 1]);
    $userController->show();
}

Using Route Parameters

Another way to call a controller from another controller is to use route parameters. This method allows you to define a route, and then call the route from within your controller. For example, if we have a controller named UserController that contains a method show, we can define a route like this:

Route::get('user/{id}', 'UserController@show');

Then, we can call this route from within another controller like this:

public function index()
{
    $this->callRoute('user.show', ['id' => 1]);
}

This approach is useful when you want to call a controller action from within a controller, but don't want to hard-code the controller name.

Conclusion

In this tutorial, we looked at how to call a controller from another controller in Laravel. We explored two techniques for doing this: using the controller method, and using route parameters. Both techniques are useful in different scenarios, and can help you keep your code organized and maintainable.
