Laravel 8 CRUD Example Tutorial

In this tutorial, I would like to show you the larval 8 crud operation example.  We will give you a simple example of how to create crud in laravel 8. you will learn crud operation in laravel 8.

So, let's follow some steps to make an example of the Larva 8 crude application tutorial.

Step 1: Install Laravel 8

first of all we need to get fresh Laravel 8 version application using bellow command, So open your terminal OR command prompt and run bellow command:

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

Step 2: Database Configuration

In the second step, we will make database configuration, for example, database name, username, password, etc. for our crud application of laravel 8. So let's open .env file and fill all details like 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

we are going to create a crud application for the product. so we have to create a migration for the "products" table using Laravel 8 PHP artisan command, so first fire bellow command:

php artisan make:migration create_products_table --create=products

After this command you will find one file in the following path "database/migrations" and you have to put bellow code in your migration file for creating 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 by the following command:

php artisan migrate

Step 4: Add Resource Route

Here, we need 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 should create a new controller as ProductController. So run bellow command and create new controller. bellow controller for creating a resource controller.

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

After the bellow command, you will find a new file in this path "app/Http/Controllers/ProductController.php".

In this controller will create seven methods by default as bellow methods:

1)index()

2)create()

3)store()

4)show()

5)edit()

6)update()

7)destroy()

So, let'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');
    }
}

Ok, so after run bellow command you will find "app/Models/Product.php" and put 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 last step. In this step we have to create just blade files. So mainly we have to create layout file and then create new folder "products" then create blade files of crud app. So finally you have 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 let's just create following file and put bellow code.

resources/views/products/layout.blade.php
