Why Change “Add to Cart” to “Product Already in Cart”?

Online shoppers often click “Add to Cart” multiple times—either by accident or because they forget they’ve already added an item. This can lead to:

Duplicate items in cart → Annoying checkout corrections

Confusion & frustration → Poor user experience

Abandoned carts → Lost sales

By displaying “Product Already in Cart”, you:

✅ Improve clarity – Customers instantly know the item is added

✅ Reduce errors – Prevent accidental duplicate orders

✅ Enhance UX – Smoother, more intuitive shopping

3 Easy Ways to Implement This Change

Method 1: Using WooCommerce (PHP Snippet)

Go to Appearance > Theme File Editor (or use FTP).

Open functions.php and add:

add_filter('woocommerce_product_add_to_cart_text', 'change_cart_button_text', 10, 2);
function change_cart_button_text($text, $product) {
    if (WC()->cart->find_product_in_cart(WC()->cart->generate_cart_id($product->get_id()))) {
        return __('Already in Cart', 'woocommerce');
    }
    return $text;
}

Save & test!

Method 2: Using a Plugin (No Code)

Install “WooCommerce Custom Add to Cart Button” or “YITH WooCommerce Customize My Account Page”.

Configure the button text for products in cart.

Method 3: Custom CSS (Visual Feedback)

Add this CSS to Customizer > Additional CSS:

.added_to_cart {
    display: none !important;
}
.product_in_cart .add_to_cart_button {
    background: #cccccc !important;
    cursor: not-allowed;
}

Save & refresh!
