Laravel Livewire Add or Remove Dynamically Input Fields

Step 1: Install Laravel App
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 we need to create a fresh laravel project, download and install Laravel using the below command

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

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

Step 2: Add Database Detail

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .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

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

Now, in this step we will create model and migration file. Please run the following command:

 php artisan make:model Employee -m

1	php artisan make:model Employee -m

The above command will create a model name Employee.php, and create a migration name create_employees_table.php. Now, go to database/migrations folder and open create_ employees_table.php file. Then put 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');
    }
}

<?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);
 }

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

1	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 = [];
}

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Employee extends Model

{

protected $guarded = [];

}

Step 4: Install Livewire Package

In this step, we will install Livewire Package via the composer dependency manager. Use the following command to install Livewire Package.

composer require livewire/livewire

1	composer require livewire/livewire

Step 5: Create Component using Artisan

In this step we will create a component using following artisan command:

php artisan make:livewire employees

1	php artisan make:livewire employees

The above command will create a components on the following path:

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

1 2	app/Http/Livewire/Employees.php resources/views/livewire/employees.blade.php

Now, go 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.');
    }
}

<?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>

<div>

@if (session()->has('message'))

</div>

@endif

<form>

@error('name.0') <span class="text-danger error">{{ $message }}</span>@enderror

</div>

@error('email.0') <span class="text-danger error">{{ $message }}</span>@enderror

</div>

</div>

@foreach($inputs as $key => $value)

@error('name.'.$value) <span class="text-danger error">{{ $message }}</span>@enderror

</div>

@error('email.'.$value) <span class="text-danger error">{{ $message }}</span>@enderror

</div>

<button class="btn btn-danger btn-sm" wire:click.prevent="remove({{$key}})">remove</button>

</div>

@endforeach

</div>

</form>

</div>

Step 6: Add Route

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

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

Route::get('/employees', function () {

return view('home');

});

Step 7: Create View File

In this step we will create view file. Go to resources/views/ folder and create one blade view files that name home.blade.php file. Then add the following code into your home.blade.php file:

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
