Resizing Images before upload is a very primary topic but in this topic many developers get stuck. When we upload image it will be of any size but we need to resize it first before upload.

In this article, we will see the entire concept of laravel 8 to generate thumbnail images without using any jquery plugin or doing some extra effort to resize and upload images in the laravel 8 project.

This article is totally from scratch. All steps will be super easy to understand. We will upload an image, resize, upload to server and then save to database table.

We have other articles on images as –

Let’s see the topic Resize Images in Laravel 8 before uploading to server.

Let’s get started.

Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

Here is the command to create a laravel project-

composer create-project --prefer-dist laravel/laravel blog

To start the development server of Laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Install Intervention Image Package

Open project into terminal and run this given composer command. It will install the intervention image library to application.

This package helps us to create image thumbnails, watermarks, or format large image files.

$ composer require intervention/image

While working with image related stuff in PHP, make sure your PHP version should have these two most common image processing libraries GD Library and Imagick extensions enabled.

Whether your system already contains these extensions or not you can verify like this –

Create info.php file at your localhost directory
<?php phpinfo(); ?> Add this code into info.php file.
Run this file into browser

You should see these information into php information page.

GD Extension Enabled

Imagick Extension Enabled

So, these two extensions we need, if you don’t have. Please install it first.

Add Package Settings to Application

Open app.php file from /config folder.

Search for providers, add this line into array.

//...

Intervention\Image\ImageServiceProvider::class

Search for aliases, add this line into array.

//...

'Image' => Intervention\Image\Facades\Image::class

Create Model & Migration

Open project into terminal and run this command to create migration file.

$ php artisan make:model Product -m

It will create two files –

Model – Product.php at /app/Models folder
Migration file – 2021_05_04_145928_create_products_table.php at /database/migrations folder.

Open Migration file and write this complete code into it.

<?php

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

class CreateProductsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string("name", 120);
            $table->text("description");
            $table->string("image");
            $table->string("thumbnail");
            $table->integer("cost");
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('products');
    }
}

Open model file Product.php and write this complete code into it.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    use HasFactory;

    public $timestamps = false;
  
    protected $fillable = array('name', 'description', 'image', 'thumbnail', 'cost');
}

Run Migration

Next, we need to create tables inside database.

$ php artisan migrate

This command will create tables inside database.

Create Controller

Next, we need to create a controller file.

$ php artisan make:controller ProductController

It will create a file ProductController.php at /app/Http/Controllers folder.

Open ProductController.php and write this complete code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use Image;
use App\Models\Product;

class ProductController extends Controller
{
    /**
     * Layout view.
     */
    public function index()
    {
        return view('product-upload');
    }

    /**
     * Image resize & Save - Function
     */
    public function imgResize(Request $request)
    {
        $this->validate($request, [
            'name' => 'required',
            'description' => 'required',
            'image' => 'required|image|mimes:jpg,jpeg,png,svg,gif|max:2048',
            'cost' => 'required',
        ]);

        $image = $request->file('image');
        $input['product_image'] = time() . '.' . $image->extension();

        // Get path of thumbnails folder from /public
        $thumbnailFilePath = public_path('thumbnails');

        $img = Image::make($image->path());

        // Image resize to given aspect dimensions
        // Save this thumbnail image to /public/thumbnails folder
        $img->resize(110, 110, function ($const) {
            $const->aspectRatio();
        })->save($thumbnailFilePath . '/' . $input['product_image']);

        // Product images folder
        $ImageFilePath = public_path('images');

        // Store product original images
        $image->move($ImageFilePath, $input['product_image']);

        $product = new Product();

        $product->name = $request->name;
        $product->description = $request->description;
        $product->image = "/public/images/" . $input['product_image'];
        $product->thumbnail = "/public/thumbnails/" . $input['product_image'];
        $product->cost = $request->cost;

        $product->save();

        return back()
            ->with('success', 'Product uploaded');
    }
}

When we upload image, image resize code will convert image into it’s thumbnail as well.
So we will get two different images. Original image inside /images folder and thumbnail image inside /thumbnails folder.

Create Blade Layout File

Go to /resources/views folder and create a file with name product-upload.blade.php

Open product-upload.blade.php and write this complete code into it.

Create Images Folders

We need to create two folders inside /public folder which is at root.

images folder inside as /public/images – It will store original images
thumbnails inside as /public/thumbnails – It will store thumbnail images.

Create Route

Open web.php from /routes folder and add this route into it.

# Add this to header
use App\Http\Controllers\ProductController;

//...

Route::get('product-upload', [ProductController::class, 'index']);
Route::post('submit-product', [ProductController::class, 'imgResize'])->name('img-resize');

Application Testing

Run this command into project terminal to start development server,

php artisan serve

URL: http://127.0.0.1:8000/product-upload

Form submit with no data in inputs fields.

After data save to database table
