Let’s get started.


Installation of Laravel Application

Laravel Installation can be done in two ways.

  • Laravel Installer
  • By using composer

Laravel Installer

To install Laravel via Laravel installer, we need to install it’s installer first. We need to make use of composer for that.

$ composer global require laravel/installer

This command will install laravel installer at system. This installation is at global scope, so you type command from any directory at terminal. To verify type the given command –

$ laravel

This command will open a command palette of Laravel Installer.

To create ad install laravel project in system,

$ laravel new blog

With the name of blog a laravel project will be created at your specified path.

By using composer

Alternatively, we can also install Laravel by Composer command create-project. If your system doesn’t has Composer Installed, Learn Composer Installation Steps. Here is the complete command to create a laravel project-

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

After following these steps we can install a Laravel application into system.

To start the development server of Laravel –

$ php artisan serve

This command outputs –

Starting Laravel development server: http://127.0.0.1:8000

Assuming laravel already installed at system.


Create Images Folder

Go to /public folder available at application root. Create a folder with name images. We will save generated signature images inside it.

Make sure images folder should have sufficient permission to write content into it.


Create Controller

Next, we need to create a controller file.

$ php artisan make:controller ImageController

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

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

<?php
  
namespace App\Http\Controllers;
use Illuminate\Http\Request;

class ImageController extends Controller
{
    /**
     * Show the application view.
     *
     * @return \Illuminate\Http\Response
     */
    public function imageCrop()
    {
        return view('image-crop');
    }
    /**
     * Submit image upload.
     *
     * @return \Illuminate\Http\Response
     */
    public function imageCropPost(Request $request)
    {
        $data = $request->image;

        list($type, $data) = explode(';', $data);
        list(, $data)      = explode(',', $data);

        $data = base64_decode($data);
        $image_name = time() . '.png';
        $path = public_path() . "/images/" . $image_name;

        file_put_contents($path, $data);

        return response()->json(['status' => 1, 'message' => "Image uploaded successfully"]);
    }
}

Create Blade Layout File

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

Open image-crop.blade.php and write this complete code into it.

Create Route

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

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

//...

Route::get('image-crop', [ImageController::class, "imageCrop"]);
Route::post('image-crop', [ImageController::class, "imageCropPost"])->name("imageCrop");

Application Testing

Open project to terminal and type the command to start development server

$ php artisan serve

URL: http://127.0.0.1:8000/image-crop

When we hit Upload button, it will save the cropped image into images folder and also create a image preview at the right sided area.
