How to Resize Image Before Upload

The following step to complete resize thumbnail phto.

Step 1 - Install Laravel App
Step 2 - Install Package
Step 3 - Create Controller
Step 4 - Config Symlink to Link Storage File
Step 5 - Create Blade View
Step 6 - Adding Route
Step 7 - Run Laravel App

Step 1 - Install Laravel App

You have to installed Laravel framework. Read this to know how to install Laravel project.

Step 2 - Install Package

Now we will install intervention/image package, so we can use some function to resize image. Following command to install package.

composer require intervention/image

Step 3 - Create Controller

This step we will create new controller named ImageController , so first run bellow command

php artisan make:controller ImageController

After that the command will create a file. We will add two methods one is for display UI, other one is for upload and resize the image for thumbnail, so place code to resize the image as below

Open file app -> Http -> Controllers -> ImageController.blade.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Image;
use File;
class ImageController extends Controller
{
    public function showUploadUI()
    {
    	return view('uploadUI');	
    }

    public function uploadResize(Request $request)
    {
        $path = public_path('/thumbnail/');
        $request->validate([
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        ]);
        $file = $request->file('image');
        
        // Create directory if not exist
        if(!File::isDirectory($path))
        {
            File::makeDirectory($path, 0777, true, true);
        }

        // Rename by date and time
        $finalName= date("Y_m_d_h_i_sa", date(time())).".".$file->getClientOriginalExtension();

        // Resize image to thumbnail
        $img = Image::make($file->path());
        $img->resize(200, 200, function ($constraint) {
            $constraint->aspectRatio();
        })->save($path.$finalName);
        $file->storeAs("/public/images/", $finalName);
        return back()
            ->with('success','File has been uploaded.')
            ->with('image',$finalName);
    }
}

Step 4 - Config Symlink to Link Storage File

We upload and store files in storage directory. We have to link public -> uploads -> images directory in root with storage directory which located in storage -> app -> public -> images. I have written an article about how symlink in hosting and local machine.

Open file config -> filesystems.php

Change

'links' => [
        public_path('public') => storage_path('app/public'),
    ],

'links' => [
        public_path('uploads') => storage_path('app/public'),
    ],

After modified filesystems.php run command artisan below

php artisan storage:link

Step 5 - Create Blade File (View)

Now we have to create a view to display how web UI to upload and resize the image. We are going to set a button and image display after we have resized. Create a file and named as below.

Open file resources -> views -> uploadUI.blade.php

<html>
<head>
    <title>Laravel 9 Image Resize - cambotutorial.com</title>
    <link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.1.3/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
    <div class="container">
        <h2>Laravel 9 Image Resize to Thumbnail - cambotutorial.com</h2>

        <div class="card">
            <h5 class="card-header">Upload Image</h5>
            <div class="card-body">
                @if ($message = Session::get('success'))
                <div class="alert alert-success" role="alert">
                    <strong>{{ $message }}</strong>
                </div>
                <h3>Thumbnail</h3>
                <img src="{{asset('thumbnail')}}/{{ Session::get('image') }}">
                <h3>Original</h3>
                <img src="{{asset('uploads/images')}}/{{ Session::get('image') }}" width="400px">
                @endif
                @if (count($errors) > 0)
                    <div class="alert alert-danger">
                        <ul>
                            @foreach ($errors->all() as $error)
                                <li>{{ $error }}</li>
                            @endforeach
                        </ul>
                    </div>
                @endif
                <form action="{{ route('uploadImg') }}" method="POST" enctype="multipart/form-data">
                    @csrf
                    <div class="row"> <br>   
                        <div class="col-md-6">
                            <input type="file" name="image" class="form-control">
                        </div>     
                        <div class="col-md-6">
                            <button type="submit" class="btn btn-primary">Upload</button>
                        </div>     
                    </div>
                </form>
            </div>
        </div>
    </div>
</body>  
</html>

Step 6 - Adding Route

To activate view web UI to correct URL with controller we have to insert the URL in route. We have two different methods but the same URL to apply. See the below route.

Open file routes -> web.php

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\ImageController;


/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/uploadimage', [ImageController::class, 'showUploadUI'])->name("uploadUI");
Route::post('/uploadimage', [ImageController::class, 'uploadResize'])->name("uploadResize");

Step 7 - Run Laravel App

Finally, we ready to run artisan command. We are going start the Laravel server with following command.

php artisan serve

Then we will see first home page laravel project via http://localhost:8000/uploadimage
