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 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

Create Model & Migration

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

$ php artisan make:model Order -m

It will create two files –

  • Model – Order.php at /app/Models folder
  • Migration file – 2021_07_25_123805_create_orders_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 CreateOrdersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('orders', function (Blueprint $table) {
            $table->id();
            $table->string("product_name")->nullable();
            $table->string("product_id")->nullable();
            $table->string("price")->nullable();
            $table->timestamps();
        });
    }

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

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

<?php

namespace App\Models;

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

class Order extends Model
{
    use HasFactory;
}

Run Migration

Next, we need to create tables inside database.

$ php artisan migrate

This command will create tables inside database.


Dummy Data for Application

Here, you need to copy the given mysql query and run into sql tab of phpmyadmin.

--
-- Dumping data for table `orders`
--

INSERT INTO `orders` (`id`, `product_name`, `product_id`, `price`, `created_at`, `updated_at`) VALUES
(1, 'Product 1', '5483TY', '120', '2021-07-06 18:30:00', NULL),
(2, 'Product 2', '45TRGF', '523', '2021-07-08 18:30:00', NULL),
(3, 'Product 3', 'FDFG5656', '236', '2021-07-11 18:30:00', NULL),
(4, 'Product 4', 'FDGT677', '450', '2021-07-13 18:30:00', NULL);

You will see something like this after this test data insertion.


Create Controller

Next, we need to create a controller file.

$ php artisan make:controller OrderController

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

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

<?php

namespace App\Http\Controllers;

use App\Models\Order;
use Illuminate\Http\Request;

class OrderController extends Controller
{
    public function index()
    {
       $orders = Order::all();
       return view('google-bar-chart',['orders' => $orders]);   
    }
}

Create Blade Layout File

Go to /resources/views folder and create a file with name google-bar-chart.blade.php

Open google-bar-chart.blade.php and write this complete code into it.

      google.charts.setOnLoadCallback(drawChart);
 
      function drawChart() {
        var data = google.visualization.arrayToDataTable([
            ['Order Id', 'Price', 'Product Name'],
 
            @php
              foreach($orders as $order) {
                  echo "['".$order->id."', '".$order->price."', '".$order->product_name."'],";
              }
            @endphp
        ]);
 
        var options = {
          chart: {
            title: 'Bar Graph | Price',
            subtitle: 'Price, and Product Name: @php echo $orders[0]->created_at @endphp',
          },
          bars: 'vertical'
        };
        var chart = new google.charts.Bar(document.getElementById('barchart_material'));
        chart.draw(data, google.charts.Bar.convertOptions(options));
      }
    </script>
 
</body>
</html>

Create Route

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

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

//...

Route::get('google-bar-chart', [OrderController::class, 'index']);

Application Testing

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

$ php artisan serve

URL: http://127.0.0.1:8000/google-bar-chart
