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

Database Table Rows

Suppose you have a database table named as countries. In that table you have some kind of data.

For this tutorial you can take any table from your application. The table we have taken, it’s only for demonstration.


Install maatwebsite/excel Package & Configuration

Open project into terminal and run this composer command to install package.

$ composer require maatwebsite/excel

After package installation, open app.php file from /config folder. Search for providers and aliases add these –

'providers' => [
        ....
        Maatwebsite\Excel\ExcelServiceProvider::class,
],

'aliases' => [
         ....
         'Excel' => Maatwebsite\Excel\Facades\Excel::class,
],

Create Export Class

Once you will install the above package. You will see we should have a command available in artisan list i.e make:export. We will use this command to create export class.

Open terminal and run this command –

$ php artisan make:export CountryExport

It will create a file CountryExport.php file inside /app/Exports folder.

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

<?php

namespace App\Exports;

use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\AfterSheet;

class CountryExport implements FromCollection, WithHeadings, WithEvents
{
    protected $data;

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function __construct($data)
    {
        $this->data = $data;
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function collection()
    {
        return collect($this->data);
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function headings(): array
    {
        return [
            'id',
            'name',
            'sortname',
            'phoneCode'
        ];
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function registerEvents(): array
    {
        return [

            AfterSheet::class => function (AfterSheet $event) {

                $event->sheet->getDelegate()->getStyle('A1:D1')
                    ->getFill()
                    ->setFillType(\PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID)
                    ->getStartColor()
                    ->setARGB('FFA500');
            },

        ];
    }
}

Inside registerEvents, we will have event to add background color to cell data. This is A1:D1 cell selected range.


Create Controller

Next, we need to create a controller file.

$ php artisan make:controller DataExportController

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

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

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Exports\CountryExport;
use Maatwebsite\Excel\Facades\Excel;
use App\Models\Country;

class DataExportController extends Controller
{
    public function export() 
    {
        $countries = Country::select(["id", "name", "sortname", "phonecode"])->get();
          
        return Excel::download(new CountryExport($countries), 'countries.xlsx');
    }
}

Create Route

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

//...

use App\Http\Controllers\DataExportController;

Route::get('export', [DataExportController::class, 'export']);

//...

Application Testing

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

$ php artisan serve

URL: http://127.0.0.1:8000/export

Once you hit this URL, it will download the excel file with all rows from countries table with cell background color.
