Laravel 8 is an open source PHP Framework. Inside this article we will see about implementation of Laravel 4 CRUD Application Tutorial. Nowadays, every application have a common operation CRUD. CRUD stands for Create, Read, Update & Delete.

We will see, about each operation of CRUD in Laravel 8 in a very clear way. We will interact with application database, model etc.

Let’s get started CRUD Example in Laravel 8.

Installation of Laravel Application

Laravel Installation can be done in two ways.

  • Laravel Installer
  • By using composer

Laravel Installer

To install Laravel via Laravel installer, we need to install it’s installer first. We need to make use of composer for that.

$ composer global require laravel/installer

This command will install laravel installer at system. This installation is at global scope, so you type command from any directory at terminal. To verify type the given command –

$ laravel

This command will open a command palette of Laravel Installer.

To create ad install laravel project in system, 

$ laravel new blog

With the name of blog a laravel project will be created at your specified path.

By using composer

Alternatively, we can also install Laravel by Composer command create-project. If your system doesn’t has Composer Installed, Learn Composer Installation Steps. Here is the complete command to create a laravel project- 

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

After following these steps we can install a Laravel application into system.

To start the development server of Laravel – 

$ php artisan serve

This command outputs –

Starting Laravel development server: http://127.0.0.1:8000

Assuming laravel already installed at system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Create Migration

As we are going to create CRUD (Create, Read, Update, Delete) application in laravel. So let’s take an example as product.

Here we have to create a migration which creates a products table.

$ php artisan make:migration create_products_table --create=products

After running this command at your terminal, you will see one file will be created at this following path /database/migrations.

Open {timestamp}_create_products_table.php file and write this complete code into it.

<?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->integer('amount');
            $table->text('description');
            $table->timestamps();
        });
    }
  
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('products');
    }
}

Now, you have to run this given command to migrate the above file.

$ php artisan migrate

Above command will creates a products table in database.

Add Application Controller and Model

Next, we should create a new controller as ProductController. We are going to create a resource controller by running the given command.

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

This command will creates a ProductController i.e a resource controller and a model. You can find the created files at this path app/Http/Controllers/ProductController.php & model at app/Models/Product.php

In this resource controller we will have these following methods:

  • index()
  • create()
  • store()
  • show()
  • edit()
  • update()
  • delete()

Open up the model from this path app/Models/Product.php and write this updated code.

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

Open up app/Http/Controllers/ProductController.php and paste this updated code.

<?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',
            'description' => 'required',
            'amount' => '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',
            'description' => 'required',
            'amount' => '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');
    }
}

Application Resource Route Settings

Open up route configuration file web.php from path routes/web.php.

Add the following code into it.

use App\Http\Controllers\ProductController;
  
Route::resource('products', ProductController::class);

If we are interested to see the routes associated with Resource Controller, back to terminal and type command $ php artisan route:list

Adding Application Layout Files

Inside this we need to create layout files of product. Let’s create a new folder products at path resources/views/ then create blade files of CRUD application into it.

So we have to create the following bellow blade files:

  • layout.blade.php
  • index.blade.php
  • create.blade.php
  • edit.blade.php
  • show.blade.php

Open up the file resources/views/products/layout.blade.php and paste the following given code into it.

Finally, we are ready to run Laravel 8 CRUD application.

Application Testing

Open project to terminal and type the command to start development server 

$ php artisan serve

Open up the URL: http://127.0.0.1:8000/products

When we click on Add New Product button it will open http://127.0.0.1:8000/products/create

When we add products from Create Form, we will see products list at /products URL. In the list we will see the Edit & Delete button.

We hope this article helped you to learn about Laravel 8 CRUD Application Tutorial in a very detailed way.
