Hooks, filters & shortcodes

Actions

An action is a place where plugins output HTML or react to events. Return values are printed at that place.

@hooks.add_action("order_created")
def notify(order, request=None, **kwargs):
    ...

Filters

A filter receives a value and returns it modified:

@hooks.add_filter("cart_shipping")
def free_from_100(cost, cart=None, **kwargs):
    return 0 if cart.subtotal >= 100 else cost

Shortcodes

@hooks.add_shortcode("year")
def year(attrs, request=None):
    return "2026"

In text: [year]. Attributes: [produkte limit=4 kategorie="kleidung"].
