Question

我正在尝试为woocommerce编写php代码，该代码将检查特定产品是否在购物车中，如果它是真的，那么某些结帐字段将被禁用。我现在所拥有的：

add_action( 'woocommerce_before_checkout_form', 'find_product_in_cart' );

function find_product_in_cart() {
$product_id = 989; //product id which would trigger
$in_cart = false;

foreach( WC()->cart->get_cart() as $cart_item ) {
   $product_in_cart = $cart_item['product_id'];
   if ( $product_in_cart === $product_id ) $in_cart = true; // checks if the product is in cart
}
    if ( $in_cart ) {
      add_filter( 'woocommerce_billing_fields', 'woo_filter_state_billing');
      function woo_filter_state_billing( $address_fields ) {
        //sets fields to not required
          $address_fields['billing_state']['required'] = false;
          $address_fields['billing_country']['required'] = false;
          $address_fields['billing_address_1']['required'] = false;
          $address_fields['billing_city']['required'] = false;
          $address_fields['billing_postcode']['required'] = false;
          $address_fields['billing_phone']['required'] = false;
          return $address_fields;
      }

      add_filter( 'woocommerce_checkout_fields' , 'disabling' );
      function disabling($fields){
        //hides fields
        unset($fields['billing']['billing_company']);
        unset($fields['billing']['billing_address_1']);
          unset($fields['billing']['billing_city']);
        unset($fields['billing']['billing_postcode']);
        unset($fields['billing']['billing_phone']);
        unset($fields['billing']['billing_country']);
        unset($fields['billing']['billing_state']);
        return $fields;
      }
    }
}

因此，问题在于，由于某些原因，即使隐藏了字段，仍然需要保留字段。如果我将其全部剪掉：

add_filter( 'woocommerce_billing_fields', 'woo_filter_state_billing');
      function woo_filter_state_billing( $address_fields ) {
        //sets fields to not required
          $address_fields['billing_state']['required'] = false;
          $address_fields['billing_country']['required'] = false;
          $address_fields['billing_address_1']['required'] = false;
          $address_fields['billing_city']['required'] = false;
          $address_fields['billing_postcode']['required'] = false;
          $address_fields['billing_phone']['required'] = false;
          return $address_fields;
      }

并将其粘贴到functions.php中，就可以正常工作，但是它适用于每种产品，这并不好。那么，我该如何运作呢？

Answer 1

所以我设法以一种更简洁的方式重做了所有事情，并且一切正常！

add_action( 'woocommerce_before_checkout_form', 'find_product_in_cart' );

所以最后我认为，由于顶部的add_action，未设置的功能无法正常工作：

woocommerce（如果特定产品在购物车中）请禁用特定的结帐字段，否则将需要使用这些字段
