Today, I want to describe step by step crud operation with laravel 5.7 application. In this tutorial, you will learn simple insert update delete operation with laravel 5.7 from scratch. You need to follow few step and you will get basic crud stuff using controller, model, route, bootstrap 4 and blade.

As we know just yesterday, laravel introduce it's new version of laravel 5.7. in laravel 5.7 they provide several new things that might be help you in your application. They also change directory structure for blade file.

In this tutorial, you will learn very basic crud operation with laravel new version 5.7. I am going to show you step by step from scratch so, i will better to understand if you are new in laravel. So just follow listed steps:

Step 1 : Install Laravel 5.7

first of all we need to get fresh Laravel 5.7 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: Update Database Configuration

In second step, we will make database configuration for example database name, username, password etc for our crud application of laravel 5.7. 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 Table

we are going to create crud application for product. so we have to create migration for "products" table using Laravel 5.7 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 following path "database/migrations" and you have to put bellow code in your migration file for create products table.

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreateProductsTable extends Migration

{

/**

* Run the migrations.

*

* @return void

*/

public function up()

{

Schema::create('products', function (Blueprint $table) {

$table->increments('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 following command:

php artisan migrate

Step 4: Create 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

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

Step 5: Create Controller and Model

In this step, now we should 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 bellow command you will find 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\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/Product.php" and put bellow content in Product.php file:

app/Product.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model

{

protected $fillable = [

'name', 'detail'

];

}

Step 6: Create 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
