Step 5: Create ComponentHere below command help to create the component.

php artisan make:livewire students

app/Http/Livewire/Students.php

<?php

namespace AppHttpLivewire;

use LivewireComponent;
use AppStudent;
use AppHttpLivewireField;
use IlluminateHttpRequest;

class Students extends Component
{
    public $students, $first_name, $last_name, $student_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->students = Student::all();
        return view('livewire.students');
    }

    private function resetInputFields(){
        $this->first_name = '';
        $this->last_name = '';
    }

    public function store()
    {
        $validatedDate = $this->validate([
                'first_name.0' => 'required',
                'last_name.0' => 'required',
                'first_name.*' => 'required',
                'last_name.*' => 'required',
            ],
            [
                'first_name.0.required' => 'First name field is required',
                'last_name.0.required' => 'Last name field is required',
                'first_name.*.required' => 'First name field is required',
                'last_name.*.required' => 'Last name field is required',
            ]
        );

        foreach ($this->first_name as $key => $value) {
            Student::create(['first_name' => $this->first_name[$key], 'last_name' => $this->last_name[$key]]);
        }

        $this->inputs = [];

        $this->resetInputFields();

    ];
}

?>
