rpress_apply_preset_discount

Filters the preset discount code before it is applied to the cart.

Applied in rpress_apply_preset_discount() on init at priority 999. The code is read from the preset_discount session value, which is stored from a discount request parameter, and has already passed rpress_is_discount_valid(). After the filter, the returned code is applied with rpress_set_cart_discount() and the session value is cleared.

Parameters#

Parameter	Type	Description
$code	string	The sanitized discount code from the session.

Return value#

string. The discount code to apply.

Example#

function my_preset_discount( $code ) {
	return strtoupper( $code );
}
add_filter( 'rpress_apply_preset_discount', 'my_preset_discount' );

Notes#

The validity check runs before the filter, so a replacement code is not validated here.
