Add a Clear Cart button to the cart page

By default, customers empty their Sunshine Photo Cart cart by removing each item one at a time. If your clients often build large carts while browsing and then want to start over, a single Clear Cart button saves them the clicks.

This snippet adds a Clear Cart button below the cart on the cart page. When clicked, it empties the entire cart and reloads the page.

Add the following custom code to your site:

// Empty the cart when the Clear Cart button is clicked
add_action( 'init', 'sunshine_clear_cart_request' );
function sunshine_clear_cart_request() {
    if ( isset( $_GET['sunshine_clear_cart'] ) && isset( $_GET['nonce'] ) && wp_verify_nonce( $_GET['nonce'], 'sunshine_clear_cart' ) ) {
        SPC()->cart->empty_cart();
        SPC()->notices->add( __( 'Cart cleared', 'sunshine-photo-cart' ) );
        wp_safe_redirect( sunshine_get_page_permalink( 'cart' ) );
        exit;
    }
}

// Show the Clear Cart button below the cart
add_action( 'sunshine_after_cart_form', 'sunshine_clear_cart_button' );
function sunshine_clear_cart_button() {
    $clear_url = wp_nonce_url(
        add_query_arg( 'sunshine_clear_cart', 1, sunshine_get_page_permalink( 'cart' ) ),
        'sunshine_clear_cart',
        'nonce'
    );
    // Change 'Clear Cart' below to rename the button
    echo '<div id="sunshine--cart--clear-button"><a href="' . esc_url( $clear_url ) . '" class="sunshine--button-alt button button-alt">' . esc_html__( 'Clear Cart', 'sunshine-photo-cart' ) . '</a></div>';
}

The button only appears when the cart has items (this part of the page isn't shown for an empty cart), and clearing shows a "Cart cleared" message so the customer knows it worked.
