Laravel is a popular PHP framework that helps developers quickly build, test, and deploy web applications. In many applications, multimedia files such as images and pictures are essential. In this article, we will detail how to set up images in Laravel to add images and graphics to your application.
- Installing Laravel
Before you begin, you need to install Laravel on your local computer. You can go to Laravel's official website (https://laravel.com/docs/8.x/installation) to view Laravel's installation guide.
- Creating Controllers
In Laravel, controllers are used to handle user requests and return responses. Before creating a controller, you first need to create a Laravel application. After creating your Laravel application, create a new image controller using the following command:
php artisan make:controller ImageController
- SETUP STORAGE
In Laravel you can use the file system or the cloud Storage to save images and pictures. Laravel provides a simple unified API that makes switching between local file systems and cloud storage very easy.
3.1 Storage in local file system
Laravel supports storing images and pictures in local file system. You can use the following command to set up the local file system in your Laravel application:
php artisan storage:link
Alternatively, you can configure the local file system in the config/filesystems.php file:
'local' => [ 'driver' => 'local', 'root' => storage_path('app'), ],
above In the example, storage_path('app')
is the path used to store images and pictures. You can modify this path to suit your needs.
3.2 Store in cloud storage
If your application needs to process a large number of images and pictures and need to share them between different devices, they should be stored in cloud storage, Such as Amazon S3 or Google Cloud Storage.
To use cloud storage in Laravel, you need to configure cloud storage in the config/filesystems.php file:
's3' => [ 'driver' => 's3', 'key' => env('AWS_ACCESS_KEY_ID'), 'secret' => env('AWS_SECRET_ACCESS_KEY'), 'region' => env('AWS_DEFAULT_REGION'), 'bucket' => env('AWS_BUCKET'), ],
In the above example, AWS_ACCESS_KEY_ID
,AWS_SECRET_ACCESS_KEY
, AWS_DEFAULT_REGION
, and AWS_BUCKET
are the authentication details for the bucket. You need to provide these details to the cloud storage so that Laravel can access your bucket and store images and pictures in it.
- Upload Images
In Laravel, you can use the Laravel File System (IlluminateFilesystemFilesystem
) class to upload images and pictures. To start uploading files, you need to write the following code in your controller:
public function upload(Request $request) { if ($request->hasFile('image')) { $file = $request->file('image'); $fileName = $file->getClientOriginalName(); $filePath = $file->storeAs('/public', $fileName); return $filePath; } }
In the above example, we checked whether a file named image
exists in the HTTP request. If it exists, the file can be accessed using the $file
object. We use $file->getClientOriginalName()
to get the original name of the file and use the $file->storeAs()
method to store the file under the specified path and file name . In this example, we store the files in the public
directory.
- Display images
In Laravel, you can display images and pictures using the Blade template engine. For example, if you have the following code in your template:
<img src="{{ asset('storage/image.jpg') }}" alt="Image">
In the above example, we used the asset()
function to generate the URL of the image. This function will add the root URL of your Laravel application to the specified path and return the full URL of the image.
- Conclusion
In this article, we detailed the process of setting up images in a Laravel application. We learned how to use local file systems and cloud storage to manipulate images and graphics, and display them using the Laravel controller and Blade template engine. In your next Laravel project, you can use these techniques to add images and pictures and make your application richer and more attractive.

The main role of the controller in Laravel is to process HTTP requests and return responses to keep the code neat and maintainable. By concentrating the relevant request logic into a class, the controller makes the routing file simpler, such as putting user profile display, editing and deletion operations in different methods of UserController. The creation of a controller can be implemented through the Artisan command phpartisanmake:controllerUserController, while the resource controller is generated using the --resource option, covering methods for standard CRUD operations. Then you need to bind the controller in the route, such as Route::get('/user/{id

Laravel allows custom authentication views and logic by overriding the default stub and controller. 1. To customize the authentication view, use the command phpartisanvendor:publish-tag=laravel-auth to copy the default Blade template to the resources/views/auth directory and modify it, such as adding the "Terms of Service" check box. 2. To modify the authentication logic, you need to adjust the methods in RegisterController, LoginController and ResetPasswordController, such as updating the validator() method to verify the added field, or rewriting r
