sudo -u www-data php artisan make:model -c -m Product

  • Define model

    sudo -u www-data vim app/Models/Product.php
    File Content 
    <?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
  use HasFactory;

  protected $fillable = ['title', 'descript', 'price'];
}

  • Define migration according to model

    sudo -u www-data vim database/migrations/2024_09_09_082148_create_products_table.php
    File Content 
    <?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
  /**
   * Run the migrations.
   */
  public function up(): void
  {
    Schema::create('products', function (Blueprint $table) {
      $table->id();
      $table->text('title');
      $table->text('descript');
      $table->unsignedInteger('price');
      $table->timestamps();
    });
  }

  /**
   * Reverse the migrations.
   */
  public function down(): void
  {
    Schema::dropIfExists('products');
  }
};

  • Do migrate to create table in database

    sudo -u www-data php artisan migrate
sudo -u www-data php artisan migrate:status

  • Define controller

    sudo -u www-data vim app/Http/Controllers/ProductController.php
    File Content 
    <?php

namespace App\Http\Controllers;

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

class ProductController extends Controller
{
  public function index()
  {
    // Fetch all products from DB.
    $products = Product::all(); //fetch all products from DB

    return view('product.list', ['products' => $products]);
  }   

  public function create()
  {   
    return view('product.add');
  }   

  public function store(Request $request)
  {   
    $newPost = Product::create([
      'title' => $request->title,
      'short_notes' => $request->short_notes,
      'price' => $request->price
    ]);

    return redirect('product/' . $newPost->id . '/edit');
  }   

  public function show(Product $product)
  {   
    //
  }   

  public function edit(Product $product)
  {   
    return view('product.edit', [
      'product' => $product,
    ]);
  }   

  public function update(Request $request, Product $product)
  {   
    $product->update([
      'title' => $request->title,
      'short_notes' => $request->short_notes,
      'price' => $request->price
    ]);

    return redirect('product/' . $product->id . '/edit');
  }   

  public function destroy(Product $product)
  {   
    $product->delete();
    return redirect('product/');
  }
}

  • Define view

    sudo -u www-data mkdir resources/views/product

    sudo -u www-data vim resources/views/product/list.blade.php
    File Content 
    <!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Product List</title>
    <link rel="stylesheet" href="{{ asset('css/app.css') }}">

    <style>

      table
      {
        border-collapse: collapse;
      }

      th, td
      {
        padding: 5px 10px;
        border: 1px solid #000000;
      }

    </style>
  </head>
  <body>
    <div class="container">
      <h1>Product List</h1>

      <a href="/products/create" class="btn btn-primary mb-3">Add New Product</a>

      @if ($products->isEmpty())
        <p>No content available.</p>
      @else
        <table class="table table-bordered">
          <thead>
            <tr>
              <th>ID</th>
              <th>Title</th>
              <th>Description</th>
              <th>Price</th>
              <th>Actions</th>
            </tr>
          </thead>
            <tbody>
              @foreach ($products as $product)
                <tr>
                  <td>{{ $product->id }}</td>
                  <td>{{ $product->title }}</td>
                  <td>{{ $product->descript }}</td>
                  <td>{{ $product->price }}</td>
                  <td>
                    <a href="/products/{{ $product->id }}/edit" class="btn btn-warning btn-sm">Edit</a>
                    <form action="/products/{{ $product->id }}" method="POST" style="display:inline;">
                      @csrf
                      @method('DELETE')
                      <button type="submit" class="btn btn-danger btn-sm" onclick="return confirm('Are you sure you want to delete this product?')">Delete</button>
                    </form>
                  </td>
                </tr>
              @endforeach
            </tbody>
          </table>
      @endif
    </div>
  </body>
</html>

  • Define router

    sudo -u www-data vim routes/web.php
    File Content 
    <?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ProductController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider and all of them will
| be assigned to the "web" middleware group. Make something great!
|
*/

Route::get('/', function () { return view('welcome'); }); 
Route::get('/products', [ProductController::class, 'index']);
Route::get('/products/create', [ProductController::class, 'create']);
Route::post('/products/create', [ProductController::class, 'store']);
Route::get('/products/{id}', [ProductController::class, 'show']);
Route::get('/products/{id}/edit', [ProductController::class, 'edit']);
Route::put('/products/{id}', [ProductController::class, 'update']);
Route::post('/products/{id}', [ProductController::class, 'destroy']);
