Create a Shopping Cart with Laravel 6 - Part 1

Hi guys! After a long time I brought you a very important tutorial on Laravel PHP framework. So, what is meant by a shopping cart? Have you seen it? I think you must have seen. When you visit an e-commerce sites like eBay, Ali-express you can add your product choices into something like a bucket. So we can view the bucket and do some operations for them like updating quantity. After finalizing the product list, we can perform checkout which is connected with a payment gateway and provides us the ability to pay online for the products using credit/debit cards or Paypal/Stripe or Cash on delivery.

NOTE: I won't connect payment gateway in this article. Only the fully  functional shopping cart is created...!!!

Functionalities in a shopping cart

1. Add products to cart
2. Remove products from cart
3. Update quantity of products
4. Clear cart
5. Add products to wish list

Most of these functionalities will be covered in this article series!

Let's start!

Laravel 6 provides a special package to create a shopping cart. It has been developed by Darryl Fernandez for versions higher than 5.5.
https://github.com/darryldecode/laravelshoppingcart
Before Laravel 6, there was a separate package for this developed by Rob Gloudemans for versions up to 5.5.
https://github.com/Crinsane/LaravelShoppingcart

Since I use Laravel 6, I will use the first package.

Step 1 - Create a new Laravel Project

Use the below command to create a fresh project and provide a proper name.

composer create-project laravel/laravel shopping-cart

Step 2 - Install Shopping Cart Package

1. Go into the project folder and open a terminal and type the below commanf to install the package.

composer require "darryldecode/cart"

2. Open config/app.php and add this line to your Aliases array.

'Cart' => Darryldecode\Cart\Facades\CartFacade::class

Step 3 - Create Database Connection

Go to localhost/phpmyadmin and create a new database called cart.

To perform cart functionalities, we have to create a page where some products are displayed like eBay. So, let's setup a database. Open .env file and edit the code for db connection. I use DB name as cart.

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

Open config/database.php and modify the MYSQL connection.

Step 4 - Create a Product Model and Migration

We have to create a model for a Product to save products in our database. So follow me and use the below command to create model with migration.

php artisan make:model Product -m

Now there will be a migration file for products table, inside database/migration folder. Modify it like this to setup the table structure.

        Schema::create('products', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name')->unique();
            $table->string('slug')->unique();
            $table->string('details')->nullable();
            $table->double('price');
            $table->double('shipping_cost');
            $table->text('description');
            $table->integer('category_id');
            $table->unsignedInteger('brand_id')->unsigned();
            $table->string('image_path');
            $table->timestamps();
        });

Step 5 - Feed Data to the Database

Now we can feed some data into the table we have created. Laravel provides Seeders for that. Open a terminal and type this command.

php artisan make:seed ProductsTableSeeder

Now modify the Seeder created inside database/seeds folder.

<?php

use App\Product;
use Illuminate\Database\Seeder;

class ProductsTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Product::create([
            'name' => 'MacBook Pro',
            'slug' => 'macbook-pro',
            'details' => '15 inch, 1TB HDD, 32GB RAM',
            'price' => 2499.99,
            'shipping_cost' => 29.99,
            'description' => 'MackBook Pro',
            'category_id' => 1,
            'brand_id' => 1,
            'image_path' => 'macbook-pro.png'
        ]);

        Product::create([
            'name' => 'Dell Vostro 3557',
            'slug' => 'vostro-3557',
            'details' => '15 inch, 1TB HDD, 8GB RAM',
            'price' => 1499.99,
            'shipping_cost' => 19.99,
            'description' => 'Dell Vostro 3557',
            'category_id' => 1,
            'brand_id' => 2,
            'image_path' => 'dell-v3557.png'
        ]);

        Product::create([
            'name' => 'iPhone 11 Pro',
            'slug' => 'iphone-11-pro',
            'details' => '6.1 inch, 64GB 4GB RAM',
            'price' => 649.99,
            'shipping_cost' => 14.99,
            'description' => 'iPhone 11 Pro',
            'category_id' => 2,
            'brand_id' => 1,
            'image_path' => 'iphone-11-pro.png'
        ]);

        Product::create([
            'name' => 'Remax 610D Headset',
            'slug' => 'remax-610d',
            'details' => '6.1 inch, 64GB 4GB RAM',
            'price' => 8.99,
            'shipping_cost' => 1.89,
            'description' => 'Remax 610D Headset',
            'category_id' => 3,
            'brand_id' => 3,
            'image_path' => 'remax-610d.jpg'
        ]);

        Product::create([
            'name' => 'Samsung LED TV',
            'slug' => 'samsung-led-24',
            'details' => '24 inch, LED Display, Resolution 1366 x 768',
            'price' => 41.99,
            'shipping_cost' => 12.59,
            'description' => 'Samsung LED TV',
            'category_id' => 4,
            'brand_id' => 4,
            'image_path' => 'samsung-led-24.png'
        ]);

        Product::create([
            'name' => 'Samsung Digital Camera',
            'slug' => 'samsung-mv800',
            'details' => '16.1MP, 5x Optical Zoom',
            'price' => 144.99,
            'shipping_cost' => 13.39,
            'description' => 'Samsung Digital Camera',
            'category_id' => 5,
            'brand_id' => 4,
            'image_path' => 'samsung-mv800.jpg'
        ]);

        Product::create([
            'name' => 'Huawei GR 5 2017',
            'slug' => 'gr5-2017',
            'details' => '5.5 inch, 32GB 4GB RAM',
            'price' => 148.99,
            'shipping_cost' => 6.79,
            'description' => 'Huawei GR 5 2017',
            'category_id' => 2,
            'brand_id' => 5,
            'image_path' => 'gr5-2017.jpg'
        ]);
    }
}

Our seeder is ready for feed data into DB. So, open seeds/DatabaseSeeder.php file and replace the code like this.

<?php

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        $this->call(ProductsTableSeeder::class);
    }
}

Now use the following code to feed data to DB.

php artisan db:seed

NOTE:
In addition to this data, you need set of images also. According to the products i have saved, I can give you the images also. You can find it in the below DRIVE link. Unzip the archive and the images inside public folder putting them into a sub folder called images.
Link: https://drive.google.com/open?id=1LJeY2BsqN6mFlNhnnFqv8VEE-kvz6LBv

Now you should have few records in the products table in DB.

NOTE: 

If you got an error related to schema length while migrating, this is the FIX for it. Replace your Providers/AppServiceProvider.php file with this code.

Step 6 - Create a Controller For Cart

This will handle all the functionalities related to the shopping cart that we are going to build. Add the below functions to the controller to display cart page and shop page. We can create view next.

php artisan make:controller CartController

namespace App\Http\Controllers;
use App\Product;
use Illuminate\Http\Request;

class CartController extends Controller
{
    public function shop()
    {
        $products = Product::all();
        dd($products);
        return view('shop')->withTitle('E-COMMERCE STORE | SHOP')->with(['products' => $products]);
    }

    public function cart()  {
        $cartCollection = \Cart::getContent();
        dd($cartCollection);
        return view('cart')->withTitle('E-COMMERCE STORE | CART')->with(['cartCollection' => $cartCollection]);;
    }

}

Here dd() function means dump data. You can test the data is coming or not using this function in Laravel. The code after this line is not executed.

Step 7 - Configure Routes and Run

Place the below route in routes/web.php file. Then the path for cart page will be set as http://127.0.0.1:8000/cart. And the route for our shop view will be registered at http://127.0.0.1:8000.

Route::get('/', 'CartController@shop')->name('shop');

Route::get('/cart', 'CartController@cart')->name('cart.index');
Route::post('/add', 'CartController@add')->name('cart.store');
Route::post('/update', 'CartController@update')->name('cart.update');
Route::post('/remove', 'CartController@remove')->name('cart.remove');
Route::post('/clear', 'CartController@clear')->name('cart.clear');

Additionally I added 4 more routes to add products to cart, update cart and clear cart. These routes will be used later. But we have to define them in the views for now. Logic can be implemented later.

Basic setup is done now! Open terminal/cmd and type php artisan serve to run the project on your browser at http://127.0.0.1:8000.
Since we have set the base path as CartController shop function, it should dump the product details. You must get this view.

Step 8 - Create Views

Now we have to create two views  for both cart and shop pages in resources/views folder to link our cart. We named our two views as cart and shop. So create them as it is as blade files. And we need more views to create a proper content for our shop. Create the structure for views like this.

NOTE:
First of all comment out the dd($products) and dd($cartCollection) lines. Otherwise views will not be loaded.

shop.blade.php

@extends('layouts.app')

@section('content')
    <div class="container" style="margin-top: 80px">
        <nav aria-label="breadcrumb">
            <ol class="breadcrumb">
                <li class="breadcrumb-item"><a href="/">Home</a></li>
                <li class="breadcrumb-item active" aria-current="page">Shop</li>
            </ol>
        </nav>
        <div class="row justify-content-center">
            <div class="col-lg-12">

                    </div>
                </div>
                <hr>
                <div class="row">
                    @foreach($products as $pro)

                            <div class="card" style="margin-bottom: 20px; height: auto;">
                                <img src="/images/{{ $pro->image_path }}"
                                     class="card-img-top mx-auto"
                                     style="height: 150px; width: 150px;display: block;"
                                     alt="{{ $pro->image_path }}"
                                >
                                <div class="card-body">

                                    <p>${{ $pro->price }}</p>
                                    <form action="{{ route('cart.store') }}" method="POST">

OK guys! Views are ready now!!! Let's try it on browser. You should have a look like this.

CART VIEW

CART DROP-DOWN

Step 9 - Implement Add To Cart Functionality

You can clearly see there's a button for every product in shop page. It is used to add the product to the cart. This is the time to implement the logic for that functionality. Open CartController.php and place the below code.

    public function add(Request$request){
        \Cart::add(array(
            'id' => $request->id,
            'name' => $request->name,
            'price' => $request->price,
            'quantity' => $request->quantity,
            'attributes' => array(
                'image' => $request->img,
                'slug' => $request->slug
            )
        ));
        return redirect()->route('cart.index')->with('success_msg', 'Item is Added to Cart!');
    }

So, we have created the shopping cart pages add to cart functionality! I'm planning to implement the below functionalities in next article.

• Remove product from cart
• Update cart quantities
• Clear whole cart

I think you have completed the steps and did the work! If so, please wait for the next part. I will update you very soon guys!

Till then, Good Bye Guys!!!
