add_action('caddy_before_cart_screen_data', function() {
    echo '<div class="custom-banner">🎉 Big Sale Today! Get an extra 10% off at checkout!</div>';
});

Example 2: Adding a Custom Message After Cart Items

Hook: caddy_after_cart_items

add_action('caddy_after_cart_items', function() {
    echo '<div class="cart-summary-note">Want to save more? Add one more item to qualify for free shipping!</div>';
});

Example 3: Displaying a Discount Reminder After Cart Totals

Hook: caddy_after_cart_screen_totals

add_action('caddy_after_cart_screen_totals', function() {
    echo '<div class="discount-reminder">Use code <strong>SAVE10</strong> at checkout to get 10% off your order!</div>';
});

Best Practices

  • Always check for conditions (e.g., whether the cart is empty) to ensure the hook executes effectively.
  • Use priority arguments to control the order of execution when multiple hooks target the same area.
  • Avoid overwriting existing content; instead, append or prepend to maintain compatibility with other customizations.

These hooks provide robust flexibility to enhance the cart screen, helping tailor the shopping experience to meet specific needs and goals.
