I'm trying to add a deposit option just for backorder items, I found this code on here but still show's up for ALL items, not just BACKORDER, I'm trying to fix this
add_action( 'woocommerce_cart_calculate_fees', 'calculated_deposit_discount_on_backorders' );
function calculated_deposit_discount_on_backorders( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
## Set HERE your negative percentage (to remove an amount from cart total)
$percent = -.50; // 50% off (negative)
$backordered_amount = 0;
foreach( $cart->get_cart() as $cart_item ) {
if( $cart_item['data']->is_on_backorder( $cart_item['quantity'] ) ) {
$backordered_amount += $cart_item['line_total'] + $cart_item['line_tax'];
}
}
## ## CALCULATION ## ##
$calculated_amount = $backordered_amount * $percent;
// Adding a negative fee to cart amount (Including taxes)
$cart->add_fee( __('Depósito 50%', 'woocommerce'), $calculated_amount, true );
}
