In woocommerce plugin file class-wc-booking-cart-manager.php there is this code

/**
     * Constructor
     */
    public function __construct() {
        add_filter( 'woocommerce_add_cart_item', array( $this, 'add_cart_item' ), 10, 1 );
        }

/**
     * Adjust the price of the booking product based on booking properties
     *
     * @param mixed $cart_item
     * @return array cart item
     */
    public function add_cart_item( $cart_item ) {
        if ( ! empty( $cart_item['booking'] ) && ! empty( $cart_item['booking']['_cost'] ) ) {
            $cart_item['data']->set_price( $cart_item['booking']['_cost'] );
        }
        return $cart_item;
    }

I want to change add_cart_item function's code into my child theme functions.php file. I want to know how to override this plugin function.

So I did this :

remove_all_filters('woocommerce_add_cart_item');
add_filter('woocommerce_add_cart_item', 'custom_add_cart_item');

function custom_add_cart_item($cart_item) {
    if (empty( $cart_item['booking'] ) && empty( $cart_item['booking']['_cost'] ) ) {
        $cart_item['data']->set_price( 2000 );
    }
    return $cart_item;
}

As you can see, I'm setting price to 2000.

But it does not work.. Thanks for your help !

  • it is possible that you are trying to remove the filter before it was set. – Mark Kaplun Jan 29 '16 at 14:05
  • Here $cart_item is array OR object? – AddWeb Solution Pvt Ltd Jan 30 '16 at 12:00

Here is the code for overriding price of product in cart

add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );

function add_custom_price( $cart_object ) {
    $custom_price = 10; // This will be your custome price  
    foreach ( $cart_object->cart_contents as $key => $value ) {
        $value['data']->price = $custom_price;
    }
}

You are using woocommerce_add_cart_item, Please use woocommerce_before_calculate_totals.

add_action( 'woocommerce_before_calculate_totals', 'custom_add_cart_item' );

function custom_add_cart_item( $cart_object ) {
    foreach ( $cart_object->cart_contents as $key => $value ) {
        if ( empty( $value['booking'] ) && empty( $value['booking']['_cost'] ) {
            $value['data']->price = 2000;
        }
    }
}

Make sure that this code is always executable. After adding this code.
