How to download files from public storage using on Laravel framework

Laravel is a PHP framework that has been around since 2011. It was created by Taylor Otwell and is maintained by the Laravel community. It is used to build web applications using the MVC (Model View Controller) pattern. This means that it separates the logic from the presentation layer. This allows developers to focus on writing code without having to worry about how their application looks.

If you are trying to download a file that was uploaded to Google Drive but can't find it, try searching your drive using the search bar at the top right corner of the page. If you still can't find it, then try downloading the file again.

You may need to go into the folder where the file is located and click on the file name. Then select the option to download the file.

This tutorial is going to show you how to download a file from public storage using the Laravel framework.
Sometimes you need to download the file using Laravel Framework from the public storage folder

We need to create a new app a new Laravel app with a construct a controller configuration file and write the logic to download a file from the storage folder.

Set Up Controller

In this case, Laravel is a PHP framework that makes developing web applications much easier than ever before. This tutorial will show you how to create your own simple Laravel application

Create a controller called DownloadController.php inside app/Http/Controllers directory.

The command `php artisan make:controller DownloadController` is a Laravel Artisan command used to generate a new controller file named `DownloadController`.

When you run this command in the terminal within your Laravel project directory, Laravel's Artisan command-line tool will create a new controller file under the `app/Http/Controllers` directory. The file will be named `DownloadController.php`, and it will contain a basic template for a controller class.

Here's an example of what the generated `DownloadController.php` file might look like:

Once the controller is generated, you can add your own methods and logic to handle specific routes and perform actions related to downloading files or any other functionality you desire. Remember to define your routes and specify this controller as the handler for the respective routes in your application's route files.

php artisan make:controller DownloadController

The code you provided is a PHP function called `download()`. Let's break it down step by step:

1. The function `download()` is declared as a public function. This function is likely part of a class or a controller in a Laravel application.

1. Inside the function, a variable called `$path` is assigned the value of the file path. The `public_path()` function is a helper function provided by Laravel that gives you the absolute path to the `public` directory of your application. In this case, it is used to construct the path to the PDF file named "my_file.pdf" located in the "pdf" directory within the `public` directory.

1. The `response()` function is another helper function provided by Laravel. It creates an instance of the `Illuminate\Http\Response` class, which represents an HTTP response.

1. The `download()` method is called on the response object. This method is used to generate a response that prompts the user to download the file specified by the `$path` variable. It takes the file path as an argument.

1. Finally, the `return` statement returns the response, which will trigger the file download in the user's browser when this function is invoked.

To summarize, this code defines a function that generates a download response for a PDF file named "my_file.pdf" located in the "pdf" directory of the `public` directory. When this function is called, it will initiate the download of the specified file.

     

    public function download(){

            $path=publlic_path('pdf/my_file.pdf');

            return response->download($path);

        }

Create Routes

The route is the way that we can access our application from the outside world. In this tutorial, I will explain what are routes and how they work.

The code you provided is a route definition in Laravel. Let's break it down:

1. `Route::get()` is a method provided by Laravel's routing system to define a GET route.

1. `'/download'` is the URL path that the route will be mapped to. In this case, it's the `/download` path.

1. `'Pdf@download'` is the second argument passed to the `get()` method. It specifies the controller and the method that should handle the request. In Laravel's routing system, the syntax `'ControllerName@methodName'` is used to specify the controller and the method that should be invoked when the route is accessed.

   In this case, it indicates that the `download` method of the `Pdf` controller will handle the request.

To summarize, this code defines a GET route that maps the `/download` URL path to the `download` method of the `Pdf` controller. When a user visits the `/download` URL, Laravel will invoke the `download` method in the `Pdf` controller to handle the request.

    

    Route::get('/download' , Pdf@download);
