3. Building an Online Store with CodeIgniter
Let’s walk through building the core functionalities of an online store using CodeIgniter:
3.1. Setting Up
First, download and install CodeIgniter. Once installed, configure the database by editing the `application/config/database.php` file.
3.2. Products Listing
For an online store, displaying products is essential.
Model (application/models/Product_model.php):
```php
class Product_model extends CI_Model {
public function get_all_products() {
$query = $this->db->get('products');
return $query->result();
}
}
```
Controller (application/controllers/Products.php):
```php
class Products extends CI_Controller {
public function index() {
$this->load->model('Product_model');
$data['products'] = $this->Product_model->get_all_products();
$this->load->view('products/index', $data);
}
}
```
View (application/views/products/index.php):
```php
foreach ($products as $product) {
echo "<h2>" . $product->name . "</h2>";
echo "<p>" . $product->description . "</p>";
}
```
3.3. Cart Functionality
CodeIgniter provides a Cart class that makes integrating shopping cart functionalities straightforward.
Controller:
```php
public function add_to_cart($product_id) {
$product = $this->Product_model->get_product($product_id);
$data = array(
'id' => $product->id,
'qty' => 1,
'price' => $product->price,
'name' => $product->name
);
$this->cart->insert($data);
redirect('products');
}
```
3.4. Checkout & Payment
For payments, you can integrate third-party gateways like Stripe, PayPal, etc. CodeIgniter’s flexibility ensures smooth integration.
Controller:
```php
public function checkout() {
// Load payment gateway library and process payment
// On success, save order details to the database
// Redirect to a thank you page
}
```
4. Extending Functionality
Apart from the basics, modern e-commerce platforms also provide features like:
– User authentication
– Product search and filters
– Product reviews and ratings
– Order management
CodeIgniter’s extensive libraries and helper functions make it easy to add these features.
Final Thoughts
CodeIgniter offers a blend of performance, flexibility, and simplicity that’s ideal for e-commerce development. It takes care of many technical aspects, allowing developers to focus on the business logic and user experience. If you’re considering building a formidable online store, hiring CodeIgniter developers can be a game-changer.
