顯示除產品ID32之外的所有WooCommerce產品的自定義復選框

我使用下面的代碼段來顯示所有產品的自定義復選框，但如果 ID 32 的產品在購物車中，則希望隱藏/不顯示它。我如何修改此代碼以實作這一目標？提前致謝。

add_action( 'woocommerce_review_order_before_submit', 'bbloomer_add_checkout_privacy_policy', 9 );
    
function bbloomer_add_checkout_privacy_policy() {
   
woocommerce_form_field( 'privacy_policy', array(
   'type'          => 'checkbox',
   'class'         => array('form-row privacy'),
   'label_class'   => array('woocommerce-form__label woocommerce-form__label-for-checkbox checkbox'),
   'input_class'   => array('woocommerce-form__input woocommerce-form__input-checkbox input-checkbox'),
   'required'      => true,
   'label'         => 'I\'ve read and accept the <a href="/privacy-policy">Privacy Policy</a>',
)); 
   
}
   
// Show notice if customer does not tick
    
add_action( 'woocommerce_checkout_process', 'bbloomer_not_approved_privacy' );
   
function bbloomer_not_approved_privacy() {
    if ( ! (int) isset( $_POST['privacy_policy'] ) ) {
        wc_add_notice( __( 'Please acknowledge the Privacy Policy' ), 'error' );
    }
}

uj5u.com熱心網友回復：

在您實際顯示復選框欄位之前，您首先必須瀏覽購物車以查看 productID 是否不存在。

驗證也是如此，因為它是一個必填欄位，否則即使它不存在，它仍然是一個必填欄位。

所以你得到：

// Function to check if a certain product ID is in cart
function is_product_in_cart() {
    // Check if product in cart
    // Multiple product IDs can be entered, separated by a comma
    $targeted_ids = array( 32, 1234, 5678 );
    
    // Flag no product in cart
    $flag = false;
    
    // WC Cart NOT null
    if ( ! is_null( WC()->cart ) ) {
        // Loop through cart items
        foreach( WC()->cart->get_cart() as $cart_item ) {
            // Check cart item for defined product Ids
            if ( in_array( $cart_item['product_id'], $targeted_ids ) ) {
                // Product is in cart
                $flag = true;
                
                // Break loop
                break;
            }
        }
    }

    return $flag;
}

// Add field 
function action_woocommerce_review_order_before_submit() {    
    // NOT true
    if ( ! is_product_in_cart() ) {
        // Add checkbox
        woocommerce_form_field( 'privacy_policy', array(
            'type'          => 'checkbox',
            'class'         => array( 'form-row privacy' ),
            'label_class'   => array( 'woocommerce-form__label woocommerce-form__label-for-checkbox checkbox' ),
            'input_class'   => array( 'woocommerce-form__input woocommerce-form__input-checkbox input-checkbox' ),
            'required'      => true,
            'label'         => 'I\'ve read and accept the <a href="/privacy-policy">Privacy Policy</a>',
        ));
    }
}
add_action( 'woocommerce_review_order_before_submit', 'action_woocommerce_review_order_before_submit', 9 );

// Validate
function action_woocommerce_checkout_process() {
    // NOT true
    if ( ! is_product_in_cart() ) {
        // NOT isset
        if ( ! isset( $_POST['privacy_policy'] ) ) {
            wc_add_notice( __( 'Please acknowledge the Privacy Policy', 'woocommerce' ), 'error' );
        }
    }
}
add_action( 'woocommerce_checkout_process', 'action_woocommerce_checkout_process', 10, 0 );

// Save field
function action_woocommerce_checkout_create_order( $order, $data ) {
    // Isset    
    if ( isset( $_POST['privacy_policy'] ) ) {
        $order->update_meta_data( 'privacy_policy', sanitize_text_field( $_POST['privacy_policy'] ) );
    } 
}
add_action( 'woocommerce_checkout_create_order', 'action_woocommerce_checkout_create_order', 10, 2 );
