Hello Dev.

nowadays i will offer instance of crud operation in laravel 8. in this articles you may analyze laravel 8 crud application with example little by little. this article will come up with simple instance of build a laravel 8 CRUD utility. comply with bellow article step of laravel 8 CRUD operation example. this article provide an explanation for you CRUD operation with code and instance.

So, let's start few step to create example of laravel 8 crud utility. You just want to follow few step and you may get basic CRUD stuff using controller, model, route, bootstrap 4 and blade.

In this article, you may study very fundamental CRUD operation with laravel. i'm going to expose you little by little from scratch so its easy to setup, it's going to higher to understand if you are new on laravel 8.


Step 1: Install Laravel 8

first of all we want to get clean and new Laravel eight version application the use of bellow command, now open your terminal OR command prompt and then fire bellow command and run it:

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


Step 2: Configuration of Database

second step, we configure database like database name, username, password etc for CRUD application of laravel 8. let's open .env file and fill complete details equal as bellow:
.env

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


Step 3: Create Migration 

next we're going to create CRUD application for product. so we have to create migration for "products" table the usage of Laravel 8 php artisan command, so first run bellow command:

php artisan make:migration create_products_table --create=products

After run this command you may discover one file in following path "database/migrations" and you have to placed bellow code in your migration file for create products table.

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

Now you have to run this migration via firing command:

php artisan migrate


Step 4: Add Resource Route 

here, we want to add resource route for product CRUD application. so open your "routes/web.php" file and add following route.
routes/web.php

use App\Http\Controllers\ProductController; 

Route::resource('products', ProductController::class);


Step 5: Add Controller and Model

in this step, now we have to create new controller as ProductController. So run bellow command and create new controller. bellow controller for create resource controller.

php artisan make:controller ProductController --resource --model=Product

After run command you will discover new file at the path "app/Http/Controllers/ProductController.php".

in this controller you will create seven methods by using default as bellow methods:

1. index()
2. create()
3. store()
4. show()
5. edit()
6. update()
7. destroy()

So, allow's copy bellow code and put on ProductController.php file.
app/Http/Controllers/ProductController.php

<?php
namespace App\Http\Controllers;

use App\Models\Product;
use Illuminate\Http\Request; 

class ProductController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $products = Product::latest()->paginate(5);  
        return view('products.index',compact('products'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }    
    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('products.create');
    }  
    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
            'name' => 'required',
            'detail' => 'required',
        ]);
        Product::create($request->all());    
        return redirect()->route('products.index')
                        ->with('success','Product created successfully.');
    }    
    /**
     * Display the specified resource.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function show(Product $product)
    {
        return view('products.show',compact('product'));
    }     
    /**
     * Show the form for editing the specified resource.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function edit(Product $product)
    {
        return view('products.edit',compact('product'));
    }   
    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, Product $product)
    {
        $request->validate([
            'name' => 'required',
            'detail' => 'required',
        ]);   
        $product->update($request->all());   
        return redirect()->route('products.index')
                        ->with('success','Product updated successfully');
    }   
    /**
     * Remove the specified resource from storage.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function destroy(Product $product)
    {
        $product->delete();
            return redirect()->route('products.index')
                        ->with('success','Product deleted successfully');
    }
}

adequate, so after run bellow command you will find "app/Models/Product.php" and placed bellow content in Product.php file:
app/Models/Product.php

<?php 
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;  
class Product extends Model
{
    use HasFactory;  
    protected $fillable = [
        'name', 'detail'
    ];
}


Step 6: Add Blade Files

In closing step we ought to create simply blade files. So specifically we should create layout file after which create new folder "products" then create blade files of CRUD app. So in the end you need to create following bellow blade file:

1. layout.blade.php
2. index.blade.php
3. create.blade.php
4. edit.blade.php
5. show.blade.php

So permit's simply create following file and put bellow code.
resources/views/products/layout.blade.php

                    @csrf
