基于Woocommerce中嵌套IF语句中的多个数组的条件

Question

Basically I'm trying to get the second IF statement to work if the criteria of the first If statement is met.

The fisrt IF statement is meant to check against user roles and if it matches with "bba" or "duk", then then second IF statement will check for specific product ids that should not match avoiding a custom cart wide bulk discount.

I know the second IF statement works as it works by itself but it disables the bulk discount for all users instead of specific defined ones.

This is my code:

if ( in_array( 'bba', 'duk' (array) $user->roles ) ) {

    if( ! in_array($values['product_id'], array('493','387'))){
      $quantiy_total += $values['quantity'];  
      //$price = get_post_meta($values['product_id'] , '_price', true);

      $price = $values['line_subtotal'];

     // echo "####".$price."####";


      $cart_total += $price;
    }   

  }
  }

Or my second attempt that doesn’t work either:

if ( ! in_array($user['roles'], array('bba','duk'))){

    if( ! in_array($values['product_id'], array('493','387'))){
      $quantiy_total += $values['quantity'];  
      //$price = get_post_meta($values['product_id'] , '_price', true);

      $price = $values['line_subtotal'];

     // echo "####".$price."####";


      $cart_total += $price;
    }   

  }
  }

With both codes the bulk discount is disabled for product IDs 439 and 387 without taking into account the First IF statement.

How can I make the First IF statement working and checking for the targeted user roles?

Any help is appreciated.

Answer 1

In your first IF with 2 arrays you need to use array_intersect() instead of in_array().

There is also some other mistakes. Try the following:

$cart = WC()->cart; // (If needed) The cart object

$total_quantity = $total_amount = 0; // Initializing variables

if ( array_intersect( array('bba','duk'),  $user['roles'] ) ) {
    // Loop through cart items
    foreach( $cart-get_cart() as $cart_item )
        if ( ! in_array( $cart_item['data']->get_id(), array('493','387') ) ) {
            // Cumulated total quantity of targeted cart items
            $total_quantity += $cart_item['quantity'];

            // The product price
            // $price = $cart_item['data']->get_price();

            // The line item subtotal not discounted (product price x quantity)
            $subtotal_price = $cart_item['line_subtotal'];

            // The line item total discounted ( (product price x quantity) - coupon discount )
            // $total_price = $cart_item['line_total'];

            // Cumulated line subtotals amount of targeted cart items
            $subtotal_amount += $subtotal_price;
        }
    }
}

// Testing output
echo '<p>Total quantity is ' . $total_quantity . ' and Subtotal amount is ' . $subtotal_amount . '</p>';

It should better work now.
