1. Install Package

Requirement –

  • PHP: ^7.2\|^8.0
  • Laravel: ^5.8
  • PhpSpreadsheet: ^1.21
  • psr/simple-cache: ^1.0
  • PHP extension php_zip enabled
  • PHP extension php_xml enabled
  • PHP extension php_gd2 enabled
  • PHP extension php_iconv enabled
  • PHP extension php_simplexml enabled
  • PHP extension php_xmlreader enabled
  • PHP extension php_zlib enabled

Install the package using composer –

composer require maatwebsite/excel

If you are getting an error while executing the above command then execute the below command –

composer require psr/simple-cache:^1.0 maatwebsite/excel

After that again execute –

composer require maatwebsite/excel

2. Update app.php

  • Open config/app.php file.
  • Add the following Maatwebsite\Excel\ExcelServiceProvider::class in 'providers' –
'providers' => [
      ....
      ....
      ....  
      Maatwebsite\Excel\ExcelServiceProvider::class
];
  • Add the following 'Excel' => Maatwebsite\Excel\Facades\Excel::class in 'aliases' –
'aliases' => [
     .... 
     .... 
     .... 
     'Excel' => Maatwebsite\Excel\Facades\Excel::class
];

3. Publish package

Run the command –

php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider" --tag=config

This will create a new excel.php file in config/.

4. Database Configuration

Open .env file.

Specify the host, database name, username, and password.

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

5. Create Table

  • Create a new table Employees using migration and add some records.
php artisan make:migration create_employees_table
  • Now, navigate to database/migrations/ folder from the project root.
  • Find a PHP file that ends with create_employees_table and open it.
  • Define the table structure in the up() method.
public function up()
{
    Schema::create('employees', function (Blueprint $table) {
        $table->id();
        $table->string('username');
        $table->string('name');
        $table->string('email');
        $table->smallInteger('age');
        $table->timestamps();
    });
}
  • Run the migration –
php artisan migrate
  • The table has been created.

6. Model

  • Create Employees Model.
php artisan make:model Employees
  • Open app/Models/Employees.php file.
  • Specify mass assignable Model attributes – username, name, email, and age using the $fillable property.

Completed Code

<?php

namespace App\Models;

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

class Employees extends Model
{
    use HasFactory;

    protected $fillable = [
       'username','name','email','age'
    ];
}

7. Create Import class

I am creating 2 import classes just for example purpose –

1. EmployeesImport Class –

php artisan make:import EmployeesImport --model=Employees
  • Open app/Imports/EmployeesImport.php file.
  • Class has 1 method –
    • model() – Read values from $row Array and insert a record if email id does not exists in the employees table otherwise return null.

NOTE – This import class start reading records from 1st row. I explained how to skip 1st row that contains heading in the next Import class.

CSV file with no heading row –

user1 User1 u1 user1@makitweb.com 28
user2 User2 u2 user2@makitweb.com 24

Completed Code

<?php
namespace App\Imports;

use App\Models\Employees;
use Maatwebsite\Excel\Concerns\ToModel;

class EmployeesImport implements ToModel {
    /**
    * @param array $row
    *
    * @return \Illuminate\Database\Eloquent\Model|null
    */
    public function model(array $row) {
 
       // Check email already exists
       $count = Employees::where('email',$row[2])->count();
       if($count > 0){
          return null;
       }
       return new Employees([
          'username' => $row[0],
          'name' => $row[1], 
          'email' => $row[2],
          'age' => $row[3],
       ]);
    }

}

2. Employees2Import Class –

php artisan make:import Employees2Import --model=Employees
  • Open app/Imports/Employees2Import.php file.
  • Class has 2 method –
    • collection() – Validate $rows Array data. If successfully validated then insert record if email id does not exists in the employees table otherwise return error.

NOTE – If  WithHeadingRow is implemented then $rows Arrays contains row heading as key names instead of index.

    • headingRow() – Return heading index position.

CSV file with heading row –

Username Name Email Age
yssyogesh Yogesh singh yogesh@makitweb.com 28
bsonarika Sonarika Bhadoria bsonarika@makitweb.com 28
vishal Vishal Sahu vishal@makitweb.com 31

Completed Code

<?php

namespace App\Imports;

use App\Models\Employees;
use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\ToCollection;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
use Illuminate\Support\Facades\Validator;

class Employees2Import implements ToCollection ,WithHeadingRow
{

    public function collection(Collection $rows){

       // Validate
       Validator::make($rows->toArray(), [
          '*.username' => 'required|string',
          '*.name' => 'required|string',
          '*.email' => 'required|email',
          '*.age' => 'required|integer',
       ],[
          '*.username.required'=> "The username field is required.",
          '*.username.string'=> "The username must be string.",
          '*.name.required'=> "The name field is required.",
          '*.name.string'=> "The name must be string.",
          '*.email.required'=> "The email field is required.",
          '*.email.email'=> "The email must be a valid email address.",
          '*.age.integer'=> "The age must be an integer."
       ])->validate();

       foreach ($rows as $row) {

          // Check email already exists
          $count = Employees::where('email',$row['email'])->count();
          if($count > 0){
             continue;
          }
          Employees::create([
             'username' => $row['username'],
             'name' => $row['name'], 
             'email' => $row['email'],
             'age' => $row['age'],
         ]);
       }
    }

    // Specify header row index position to skip
    public function headingRow(): int {
       return 1;
    }
}

8. Route

  • Open routes/web.php file.
  • Define 3 routes –
    • / – Load index view.
    • employees/importdata – Post route to Import data.
    • employees/validateandimportdata – Post route to validate and import data.

Completed Code

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\EmployeesController;

Route::get('/', [EmployeesController::class, 'index'])->name('home'); 
Route::post('employees/importdata/', [EmployeesController::class, 'importData'])->name('employees.importdata');
Route::post('employees/validateandimportdata/', [EmployeesController::class, 'validateAndImportdata'])->name('employees.validateandimportdata');

9. Controller

  • Create EmployeesController Controller.
php artisan make:controller EmployeesController
  • Open app/Http/Controllers/EmployeesController.php file.
  • Import EmployeesImport,  Employees2Import and Excel.
  • Create 3 methods –
    • index() – Load index view.
    • importdata() – To import call Excel::import().

Pass 2 parameters –

    1. EmployeesImport Class instance.
    2. Pass selected file ‘temp’ location.
    • validateAndImportdata() – Again call Excel::import().

Pass 2 parameters –

    1. Employees2Import Class instance.
    2. Pass stored file location (I have stored the file in public/employees.xlsx folder).

Completed Code

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Imports\EmployeesImport;
use App\Imports\Employees2Import;
use Excel;

class EmployeesController extends Controller
{
   public function index(){
      return view('index');
   }

   // Import data 
   public function importdata(Request $request){
      Excel::import(new EmployeesImport, $request->file('file')->store('temp'));
      return back()->with('success', 'Import successfully!');
   }

   // Validate and Import data 
   public function validateAndImportdata(Request $request){

      Excel::import(new Employees2Import, "employees.xlsx");
      return back()->with('success', 'Import successfully!');
   }

}

10. View

Create index.blade.php file in resources/views/ folder.

Create 2 <form> –

  • In the 1st <form > set action to {{ route('employees.importdata') }}. Create a file element and a submit button.
  • In the 2nd <form> set action to {{ route('employees.validateandimportdata') }}. Create a submit button.

Loop on $errors->all() to display errors.

12. Conclusion

Make sure to validate the record before inserting or updating records in the Import class. Specify WithHeadingRow in Import class only if the import file has a header row.
