Hello Readers,

In previous two blogs we have seen how to install laravel and livewire and simple score App.

I assume, you have the basic knowledge of how does livewire works. If you not know please refer my previous blogs and then see this post which will help you to understand it better.      

- [How to install Laravel and Livewire](https://dev.to/snehalk/laravel-and-livewire-36m)
- [Score App using Laravel and Livewire](https://dev.to/snehalk/score-app-using-laravel-and-livewire-7ep)

In today’s blog we will see CRUD operation using laravel n Livewire.

So let’s begin with our CRUD example.

**Step 1 -** First thing first - create a migration for product table 
`php artisan make:migration “create products table”`

Open your newly create migration file and add following fields to it and run `php artisan migrate` command

```php
 Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string('pname');
            $table->bigInteger('price');
            $table->integer('quantity');
            $table->timestamps();
        });
```
**Step 2 -** open your web.php file and add routes
```php
    // routes for product
    Route::get('/products', function () {
        return view('product');
    })->name('products');

    Route::get('/products/restore/{id}', [Products::class, 'restore'])->name('products.restore');
    Route::get('/products/permenatly/delete/{id}', [Products::class, 'delete'])->name('products.delete');
```

**Step 3 -** Now we will create livewire component using below command which will create two files one is Class and second one is view file, as you already know.

`php artisan make:livewire Product`

Open your view file and add below code to it.

```php
<div class="max-w-5xl mx-auto my-10">
    {{-- Success is as dangerous as failure. --}}
    <div class="w-full">
        @if (session()->has('message'))
        <div class="w-1/3 p-2 text-center mx-auto my-4 rounded border border-green-400 bg-green-600 text-green-300">
            {{ session('message') }}
        </div>
        @endif
    </div>
    <div class="mb-10">
        @if ($openUpdateMode)
        @include('livewire.products.create-product')
        @else
        @include('livewire.products.create-product')
        @endif
    </div>
    <!-- dropdown -->
    <div class="relative inline-block text-left mb-10">
        <div>
            <button type="button" wire:click="openDropDown"

                                        <button wire:click="archive({{ $product->id }})"
                                            class="text-red-600 hover:text-red-900">
                                            <svg xmlns="http://www.w3.org/2000/svg" class="h-6 w-6" fill="none" viewBox="0 0 24 24" stroke="currentColor">

                                    @endif
                                </td>
                            </tr>
                            @endforeach
                        </tbody>
                    </table>
                </div>
            </div>
        </div>
    </div>
</div>
```
**Step 4** create another file which is used to add products and name it as `create.blade.php` (you can create a file by right clicking livewire folder within a view folder, add below code.

```php
<div class="mt-10 sm:mt-0">
    <div class="mt-5 md:mt-0 md:col-span-2">
        <form>
            <div class="shadow overflow-hidden sm:rounded-md">
                <div class="px-4 py-5 bg-white sm:p-6">
                    <div class="grid grid-cols-6 gap-6">
                        <div class="col-span-6 sm:col-span-3">
                            <label for="product_name" class="block text-sm font-medium text-gray-700">Product

                            <input type="text" wire:model="pname" name="product_name" id="product_name" autocomplete="given-name"
                                class="mt-1 focus:ring-indigo-500 focus:border-indigo-500 block w-full shadow-sm sm:text-sm border-gray-300 rounded-md">
                        </div>

                        <div class="col-span-6 sm:col-span-3">
                            <label for="price" class="block text-sm font-medium text-gray-700">Price</label>
                            <input type="text" wire:model="price" name="price" id="price" autocomplete="family-name"
                                class="mt-1 focus:ring-indigo-500 focus:border-indigo-500 block w-full shadow-sm sm:text-sm border-gray-300 rounded-md">
                        </div>

                        <div class="col-span-6 sm:col-span-3">
                            <label for="quantity" class="block text-sm font-medium text-gray-700">Quantity</label>
                            <input type="number" wire:model="quantity" name="quantity" id="quantity" autocomplete="postal-code"
                                class="mt-1 focus:ring-indigo-500 focus:border-indigo-500 block w-full shadow-sm sm:text-sm border-gray-300 rounded-md">
                        </div>
                    </div>
                </div>
                <div class="px-4 py-3 bg-gray-50 text-right sm:px-6">
                    @if ($openUpdateMode)
                        <button type="submit" wire:click.prevent="update({{ $product->id }})"
                            class="inline-flex justify-center py-2 px-4 border border-transparent shadow-sm text-sm font-medium rounded-md text-white bg-indigo-600 hover:bg-indigo-700 focus:outline-none focus:ring-2 focus:ring-offset-2 focus:ring-indigo-500">
                            Update
                        </button>
                    @else
                        <button type="submit" wire:click.prevent="store()"
                            class="inline-flex justify-center py-2 px-4 border border-transparent shadow-sm text-sm font-medium rounded-md text-white bg-indigo-600 hover:bg-indigo-700 focus:outline-none focus:ring-2 focus:ring-offset-2 focus:ring-indigo-500">
                            Save
                        </button>
                    @endif
                </div>
            </div>
        </form>
    </div>
</div>
```

**Step 5 -** Last step open your Class/Controller file `Product.php` and add below code.

```php
<?php

namespace App\Http\Livewire\Products;

use Livewire\Component;
use App\Models\Product;
use Illuminate\Support\Str;

class Products extends Component
{
    public $pname, $price, $quantity, $products, $product;
    public $openUpdateMode = false, $open = false, $archivedProduct = false;

    public function mount(Product $product)
    {
        $this->pname = $product->pname ? $product->pname : "";
        $this->price = $product->price ? $product->price : "";
        $this->quantity = $product->quantity ?  $product->quantity : "";
        $this->product = $product;
    }

    // create product
    public function store()
    {
        $data = $this->validate([
            'pname' => 'required',
            'price' => 'required',
            'quantity' => 'required',
        ]);

        Product::create($data);
        session()->flash('message', 'Product Created Successfully.');

    }

    // edit product
    public function edit(Product $product)
    {
        $this->openUpdateMode = true;
        $this->mount($product);
    }

    // update product
