php - Replace a value in object array

Solution:

This is what you wanted?

$wc_cart->cart_contents['d6f5bb0bbc']['quantity'] = 3;
Copy code

A few examples of accessing arrays and objects:

$object->some_property
$object->{'complex'.'property'.'name'.(2*3)}
$array[12]
$array['hello']
$array[ $array_index*10 ]
Copy code

• Objects: http://www.php.net/manual/en/language.oop5.basic.php

Solution:

There are actions and filters in WordPress, they are different:

In WooCommerce there are two very similarly named action/filter:

• woocommerce_calculate_totals action
• woocommerce_calculated_total filter

woocommerce_calculate_totals actions are called with the cart object, so what you should do (and hopefully should work) is:

add_action( 'woocommerce_calculate_totals', 'my_quantity' );

function my_quantity( $wc_cart ){
  $wc_cart->cart_contents['d6f5bb0bbc']['quantity'] = 3;
}
Copy code

Solution:

First getcart_contents out of the object, then work your way through the arrays:

$wc_cart->cart_contents['d6f5bb0bbc']['quantity'] = 3;
Copy code
