How to set up laravel images

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.

1. 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.

2. 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

3. 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.

4. 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.

5. 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.

6. 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.
