How to Implement a Recommender System in WooCommerce

Table of Contents


WooCommerce is an open source ecommerce platform that allows businesses to sell their products online. One of the main benefits of WooCommerce is that it is highly customizable and can be extended through plugins and extensions. In this post, we will discuss how to implement a recommender system in WooCommerce.

A recommender system is a type of artificial intelligence algorithm that analyzes user behavior and suggests products that the user may be interested in. The goal of a recommender system is to increase user engagement on a website and ultimately increase sales.

Implementing a Recommender System in WooCommerce

To implement a recommender system in WooCommerce, we will need to analyze user behavior, store that data, and use it to provide recommendations. There are several steps involved in this process:

1. Collect user data: In order to power a recommender system, we need data on user behavior. We can collect this data by tracking actions such as product views, purchases, and cart additions.

2. Store the data: Once we have collected the data, we need to store it in a way that is easily accessible. One option is to use a relational database such as MySQL.

3. Analyze the data: The next step is to analyze the data to identify user behavior patterns. There are several machine learning algorithms that can be used for this, including collaborative filtering and content-based filtering.

4. Provide recommendations: Once we have analyzed the data, we can use it to provide personalized recommendations to users. We can display these recommendations on product pages, in search results, or in a dedicated Recommendations section.

Code Sample for Storing User Data

Here is an example of how you can store user data in a database using PHP:

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);

// Collect user data
$user_id = get_current_user_id();
$product_id = get_the_ID();
$action = 'view'; // or 'add_to_cart' or 'purchase'

// Store data in MySQL database
$sql = "INSERT INTO user_data (user_id, product_id, action) VALUES ('$user_id', '$product_id', '$action')";

if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "
" . $conn->error;


This code will store user data in a MySQL database whenever a user views a product page, adds a product to their cart, or makes a purchase.
