How to Upload Multiple Images Into A Database Using Laravel?

6 minutes read

To upload multiple images into a database using Laravel, you can follow these steps:

  1. First, make sure you have a database table set up to store the images. You can create a migration file to define the schema of the table.
  2. Create a form in your blade file with an input field of type file, set to allow multiple file uploads.
  3. In your controller, create a method to handle the form submission. Use the request object to retrieve the uploaded files.
  4. Loop through the files and store each one in a designated directory on your server. You can use the Storage Facade provided by Laravel to make this process easier.
  5. Once the files are stored on the server, save the file paths in the database table along with any other relevant information such as the user who uploaded them.
  6. You can now retrieve and display the images from the database in your views.


By following these steps, you can successfully upload multiple images into a database using Laravel.


How to create a model for images in Laravel?

To create a model for images in Laravel, follow these steps:

  1. Generate a new model using the Artisan command line tool. Run the following command in your terminal:
1
php artisan make:model Image


This will create a new model file in the app directory with the name Image.php.

  1. Define the properties of the Image model in the Image.php file. For example, you may want to add columns for the image file name, file path, and any other relevant information. Here is an example of how you might define the model:

namespace App;

use Illuminate\Database\Eloquent\Model;

class Image extends Model
{
    protected $fillable = [
        'file_name', 'file_path',
    ];
}


  1. Run a migration to create the corresponding database table for the Image model. Create a new migration file using the Artisan command:
1
php artisan make:migration create_images_table


Open the newly created migration file in the database/migrations directory and define the schema for the images table. Here is an example of how you might define the schema:

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateImagesTable extends Migration
{
    public function up()
    {
        Schema::create('images', function (Blueprint $table) {
            $table->id();
            $table->string('file_name');
            $table->string('file_path');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('images');
    }
}


  1. Run the migration to create the images table in your database:
1
php artisan migrate


  1. Your Image model is now ready to be used in your Laravel application. You can create, retrieve, update, and delete images using the model methods provided by Eloquent.

            $images = $request->file('images');

            foreach($images as $image) {
                $filename = $image->getClientOriginalName();
                $image->storeAs('images', $filename, 'public');
            }

            // Save the image paths or perform any other desired operations
            return redirect()->back()->with('success', 'Images uploaded successfully.');
        }

        return redirect()->back()->with('error', 'No images selected for upload.');

    @endif

    @if(session('error'))
        <p>{{ session('error') }}</p>
    @endif
</body>
</html>


  1. Run the following command to create a symbolic link for the public storage folder:
1
php artisan storage:link


  1. Set up your storage folder permissions to allow file uploads:
1
chmod -R 777 storage


  1. You can now access the upload form at the /upload route and upload multiple images through the form. The images will be stored in the storage/app/public/images directory.


How to create a database migration in Laravel?

To create a database migration in Laravel, follow these steps:

  1. Open your terminal and navigate to the root directory of your Laravel project.
  2. Run the following Artisan command to create a new migration file:
1
php artisan make:migration create_table_name


Replace table_name with the name of the table you want to create in your database.

  1. Once the migration file is created, navigate to the database/migrations directory of your Laravel project.
  2. Open the newly created migration file in a code editor. Inside the up method, you can define the schema of the table by using Laravel's Schema Builder methods. For example, you can define columns, indexes, and foreign keys.
  3. After defining the table schema in the up method, you can also define the down method that will be used to rollback the migration. In this method, you should drop the table that was created in the up method.
  4. Save the migration file after defining the table schema and rollback logic.
  5. Run the following Artisan command to execute the migration and create the table in your database:
1
php artisan migrate


Your database migration in Laravel is now successfully created and executed. You can check your database to verify that the table has been created.


How to retrieve uploaded images from a database in Laravel?

To retrieve uploaded images from a database in Laravel, you can follow these steps:

  1. First, make sure you have a database table that stores the file paths or URLs of the uploaded images. You can use the migration tool to create a table with a column for storing image paths.
  2. In your Laravel controller, use the Eloquent ORM to query the database and retrieve the uploaded image paths. You can use the all() method to get all the records from the database table, or you can use specific conditions to filter the results.

// Example code in a controller method
$images = Image::all(); // assuming 'Image' is the model for your images database table

return view('images.index', ['images' => $images]);


  1. Pass the retrieved images data to a view file where you can display the images. You can use Blade template engine to loop through the images and display them on the front end.

<!-- Example code in a Blade view file -->
@foreach($images as $image)
    <img src="{{ $image->path }}" alt="{{ $image->name }}">
@endforeach


  1. Make sure to properly handle the storage and retrieval of images according to your application's requirements and security measures. You may need to set up a file storage system and define the appropriate configurations in your Laravel application.


By following these steps, you should be able to retrieve uploaded images from a database in Laravel and display them in your application.
