  • Step 2: Add Database Detail
  • Step 3: Create Model & Migration using Artisan
  • Step 4: Install Livewire Package
  • Step 5: Create Component using Artisan
  • Step 6: Add Route
  • Step 7: Create View File
  • Step 8: Run Development Server

Step 1: Install Laravel App

First of all, Open your terminal OR command prompt and run following command to install laravel fresh app for laravel livewire add or remove multiple input fields dynamically project:

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

Step 2: Add Database Detail

In this step, Add database credentials in the .env file. So open your project root directory and find .env file. Then add database detail in .env file:

DB_CONNECTION=mysql  
DB_HOST=127.0.0.1  
DB_PORT=3306  
DB_DATABASE=here your database name here 
DB_USERNAME=here database username here 
DB_PASSWORD=here database password here

Step 3: Run Migration

In this step, generate model, migration file using the following command:

 php artisan make:model Employee -m 

This command will create one model name Employee.php, and create one migration that name create_employees_table.php

So, Navigate to database/migrations folder and open create_ employees_table.php file. Then update the following code into create_ employees_table.php file:

<?php
  
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
  
class CreateEmployeesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('employees', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('email');
            $table->timestamps();
        });
    }
  
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('employees');
    }
}

Now, you navigate to app\Providers folder and open AppServiceProvider.php file. And update the following code into AppServiceProvider.php file:

 use Illuminate\Support\Facades\Schema;
 
public function boot()
{
    Schema::defaultStringLength(191);
}

Next, open your command prompt and run the following command to create the table into your database:

php artisan migrate

Next, Navigate to app/Employee.php and update the following code into your Employee.php model as follow:

<?php
 
namespace App;

use Illuminate\Database\Eloquent\Model;

class Employee extends Model
{
    protected $guarded = [];
}

Step 4: Install Livewire Package

In this step, you need to install livewire package to your laravel project using the following command:

composer require livewire/livewire

Step 5: Create Component using Artisan

In this step, create the livewire components for creating a livewire add or remove field component using the following command in laravel. So Open your cmd and run the following command:

php artisan make:livewire employees

This command will create the following components on the following path:

app/Http/Livewire/Employees.php
resources/views/livewire/employees.blade.php

Now, Navigate to app/Http/Livewire folder and open Employees.php file. Then add the following code into your Employees.php file:

<?php

namespace App\Http\Livewire;

use Livewire\Component;
use App\Employee;
use App\Http\Livewire\Field;
use Illuminate\Http\Request;

class Employees extends Component
{
    public $employees, $name, $email, $employee_id;
    public $updateMode = false;
    public $inputs = [];
    public $i = 1;

    public function add($i)
    {
        $i = $i + 1;
        $this->i = $i;
        array_push($this->inputs ,$i);
    }

    public function remove($i)
    {
        unset($this->inputs[$i]);
    }

    public function render()
    {
        $this->employees = Employee::all();
        return view('livewire.employees');
    }

    private function resetInputFields(){
        $this->name = '';
        $this->email = '';
    }

    public function store()
    {
        $validatedDate = $this->validate([
                'name.0' => 'required',
                'email.0' => 'required',
                'name.*' => 'required',
                'email.*' => 'required|email',
            ],
            [
                'name.0.required' => 'name field is required',
                'email.0.required' => 'email field is required',
	        'email.0.email' => 'The email must be a valid email address.',
                'name.*.required' => 'name field is required',
                'email.*.required' => 'email field is required',
                'email.*.email' => 'The email must be a valid email address.',
            ]
        );

        foreach ($this->name as $key => $value) {
            Employee::create(['name' => $this->name[$key], 'email' => $this->email[$key]]);
        }

        $this->inputs = [];

        $this->resetInputFields();

        session()->flash('message', 'Employee Has Been Created Successfully.');
    }
}

After that, Navigate to resources/views/livewire folder and open employees.blade.php file. Then add the following code into your employees.blade.php file:

<div>
    @if (session()->has('message'))
        <div class="alert alert-success">
          {{ session('message') }}
        </div>
    @endif
    <form>
        <div class=" add-input">
            <div class="row">
                <div class="col-md-5">
                    <div class="form-group">
                        <input type="text" class="form-control" placeholder="Enter Name" wire:model="name.0">
                        @error('name.0') <span class="text-danger error">{{ $message }}</span>@enderror
                    </div>
                </div>
                <div class="col-md-5">
                    <div class="form-group">
                        <input type="email" class="form-control" wire:model="email.0" placeholder="Enter Email">
                        @error('email.0') <span class="text-danger error">{{ $message }}</span>@enderror
                    </div>
                </div>
                <div class="col-md-2">
                    <button class="btn text-white btn-info btn-sm" wire:click.prevent="add({{$i}})">Add</button>
                </div>
            </div>
        </div>

        @foreach($inputs as $key => $value)
            <div class=" add-input">
                <div class="row">
                    <div class="col-md-5">
                        <div class="form-group">
                            <input type="text" class="form-control" placeholder="Enter Name" wire:model="name.{{ $value }}">
                            @error('name.'.$value) <span class="text-danger error">{{ $message }}</span>@enderror
                        </div>
                    </div>
                    <div class="col-md-5">
                        <div class="form-group">
                            <input type="email" class="form-control" wire:model="email.{{ $value }}" placeholder="Enter Email">
                            @error('email.'.$value) <span class="text-danger error">{{ $message }}</span>@enderror
                        </div>
                    </div>
                    <div class="col-md-2">
                        <button class="btn btn-danger btn-sm" wire:click.prevent="remove({{$key}})">remove</button>
                    </div>
                </div>
            </div>
        @endforeach
        <div class="row">
            <div class="col-md-12">
                <button type="button" wire:click.prevent="store()" class="btn btn-success btn-sm">Save</button>
            </div>
        </div>
    </form>
</div>

Step 6: Add Route

Route::get('/employees', function () {
    return view('home');
});

Step 7: Create View File

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
    <head>
        <meta charset="utf-8">
