Calculate Item Total

do_action_ref_array( 'vikrestaurants_calculate_item_total', float &$total, Item $item )

Fires while calculating the total amount of a take-away item.

Description

Plugins attached to this hook can change the calculated total at runtime. The total cost is meant to be before taxes.

NOTE: calling $item->getTotalCost() in this hook will result in recursion.

Parameters

&$total

(float)  The default total amount. Since this argument is passed by reference, it is possible to manipulate it.

$item

(Item)  The object holding the details of the item. This class is part of the E4J\VikRestaurants\TakeAway\Cart namespace.

Example

The example below always increases by 1 the cost of the items for guest users.

/**

 *
 * Note. Calling $item->getTotalCost() in this hook will result in recursion.
 *
 * @param  float  &$total  The calculated total cost.
 * @param  Item   $item    The item instance.

add_action('vikrestaurants_calculate_item_total', function(&$total, $item) {
    // check if we have a user not logged-in
    if (wp_get_current_user()->exists() == false) {
        // increase item price
        $total++;
    }
}, 10, 2);
