How to Save Products in Cart To Reduce Abandonment

In today’s competitive e-commerce landscape, cart abandonment is one of the biggest challenges businesses face. According to recent studies, the average cart abandonment rate is around 70%, meaning 7 out of 10 customers who add items to their cart never complete their purchase.

One of the primary reasons for this is cart loss – when users lose their carefully selected items due to browser issues, session timeouts, or device switching.

This comprehensive guide will show you how to implement robust cart saving solutions that ensure your customers never lose their shopping cart items, ultimately improving conversion rates and customer satisfaction.

Why Cart Saving is Critical for E-commerce Success

The Problem of Cart Loss

Cart loss can occur due to several reasons:

Browser crashes or refreshes
Session timeouts
Switching between devices or browsers
Cache clearing
Approval workflows that take time
Network interruptions

The Impact on Business

When customers lose their cart items, it directly affects your bottom line:

Lost sales opportunities
Frustrated customers
Increased support requests
Lower conversion rates
Negative user experience

Understanding Cart Saving Solutions

Types of Cart Storage

There are several approaches to saving cart data:

1. Session-Based Storage

Pros: Simple implementation, fast access
Cons: Lost when browser closes, doesn’t work across devices
Best for: Temporary cart storage

2. Local Storage

Pros: Persists across browser sessions, works offline
Cons: Limited to single browser, can be cleared by user
Best for: Basic cart persistence

3. Database Storage

Pros: Cross-device sync, persistent, secure
Cons: Requires server resources, more complex
Best for: Professional e-commerce sites

4. Hybrid Approach

Pros: Best of all worlds, fallback options
Cons: More complex to implement
Best for: Enterprise-level solutions

Permission Verification: Secure role checking on all operations

Implementation:

// Role verification function
public function is_user_role_allowed() {
    $allowed_roles = $options['allowed_user_roles'];
    $user_roles = wp_get_current_user()->roles;

    foreach ($user_roles as $role) {
        if (in_array($role, $allowed_roles)) {
            return true;
        }
    }
    return false;
}

Basic Implementation:

// Save cart to database
function save_user_cart($user_id, $cart_data) {
    global $wpdb;
    $table_name = $wpdb->prefix . 'user_carts';

    $wpdb->replace(
        $table_name,
        array(
            'user_id' => $user_id,
            'cart_data' => serialize($cart_data),
            'updated_at' => current_time('mysql')
        ),
        array('%d', '%s', '%s')
    );
}

// Load cart from database
function load_user_cart($user_id) {
    global $wpdb;
    $table_name = $wpdb->prefix . 'user_carts';

    $cart_data = $wpdb->get_var($wpdb->prepare(
        "SELECT cart_data FROM $table_name WHERE user_id = %d",
        $user_id
    ));

    return $cart_data ? unserialize($cart_data) : array();
}
