How to Create a WooCommerce Order in PHP
As a WordPress and WooCommerce developer, you may often find yourself in a situation where you need to programmatically create orders. This could be for a variety of reasons, such as integrating with a third-party system, automating order creation, or even just testing and debugging your WooCommerce-powered website.
In this article, we'll walk through the step-by-step process of creating a WooCommerce order using PHP. We'll cover setting the product price, adding the product to the order, and finalizing the order. By the end, you'll have a comprehensive understanding of how to create WooCommerce orders programmatically.
Prerequisite: Understanding WooCommerce Data Structures
Before we dive into the code, it's important to have a basic understanding of the key data structures in WooCommerce. The main ones we'll be working with are:
- WC_Product: Represents a product in WooCommerce. This is used to get product information and set the price.
- WC_Order: Represents an order in WooCommerce. This is used to create the order, add products, and finalize the order.
Knowing how these two classes work and how to interact with them is crucial for creating WooCommerce orders programmatically.
Step 1: Set the Product Price
The first step in creating a WooCommerce order is to set the price of the product you want to add to the order. Here's the code to do that:
global $woocommerce;
$product_id = '5617'; // a product ID or a variation ID
$new_product_price = $_POST['amount']; // the new product price
$quantity = 1; // The line item quantity
// Get an instance of the WC_Product object
$product = wc_get_product($product_id);
// Change the product price
$product->set_price($new_product_price);
In this example, we first get the global $woocommerce
object, which is a way to access the WooCommerce API. We then get the product ID (which could be a simple product or a variation) and the new product price from a form submission ($_POST['amount']
).
Next, we create a WC_Product
object using the wc_get_product()
function and then set the price of the product using the set_price()
method.
Step 2: Create the WooCommerce Order
With the product price set, we can now proceed to create the WooCommerce order. Here's the code:
// Create the order
$order = wc_create_order();
// Add the product to the order
$order->add_product($product, $quantity);
// Update the order totals
$order->calculate_totals();
// Save the order
$order->save();
In this step, we first create a new WC_Order
object using the wc_create_order()
function. This gives us a blank order that we can then populate with the product we want to add.
Next, we use the add_product()
method of the WC_Order
object to add the product to the order. We pass in the WC_Product
object we created earlier, as well as the quantity.
After adding the product, we need to update the order totals using the calculate_totals()
method. This ensures that the order total, taxes, and other relevant information are correctly calculated.
Finally, we save the order using the save()
method.
Step 3: Add Customer Data and Other Order Details (Optional)
In the example we've shown so far, we've only added the product to the order. In a real-world scenario, you'd also need to add customer information, shipping details, and other relevant order data. Here's an example of how you might do that:
// Add customer data
$order->set_customer_id(1); // Replace with the actual customer ID
$order->set_billing_first_name('John');
$order->set_billing_last_name('Doe');
$order->set_billing_email('john.doe@example.com');
$order->set_billing_phone('555-1234');
// Add shipping information
$order->set_shipping_first_name('Jane');
$order->set_shipping_last_name('Doe');
$order->set_shipping_address_1('123 Main St');
$order->set_shipping_city('Anytown');
$order->set_shipping_state('CA');
$order->set_shipping_postcode('12345');
$order->set_shipping_country('US');
// Add a coupon
$order->apply_coupon('DISCOUNT10');
// Add a note
$order->add_order_note('This is a test order');
In this example, we set the customer data, shipping information, apply a coupon, and add a note to the order. You can customize this code to fit your specific needs, depending on the information you need to include in the order.
Real-World Examples and Statistics
Now that we've covered the basic steps of creating a WooCommerce order programmatically, let's look at some real-world examples and statistics to understand the importance of this functionality.
According to a study by WooCommerce, 32% of online stores use some form of automation or integration to manage their order processing. This includes things like automatically creating orders based on customer actions, integrating with third-party shipping providers, and more.
One real-world example of programmatic order creation is in the e-commerce industry. Imagine an online store that sells personalized products. When a customer places an order, the store needs to create a unique product, add it to the order, and then process the order. This entire workflow can be automated using the techniques we've discussed in this article.
Another example is in the subscription-based business model. Many subscription services use programmatic order creation to handle recurring orders, manage payment information, and keep track of subscription status. This helps to streamline the order management process and reduce the risk of human error.
According to a report by Barilliance, abandoned cart recovery campaigns can increase conversion rates by up to 35%. One way to implement this is by programmatically creating an order when a customer abandons their cart, which can be done using the techniques we've covered.
