Cart ist eine einfache PHP-Klasse, die einen Warenkorb für REDAXO 5 ohne Checkout zur Verfügung stellt. Warenkorb-Items können in PHP-Sessions oder Browser-Cookie gespeichert werden. Cart eignet sich z.B. auch zur Erstellung einer Merkliste oder eines Wunschzettels.
Konfiguration ist möglich über die AddOn-Einstellungen oder man initialisiert den Warenkorb manuell.
$cartMaxItem = rex_addon::get('mf_cart')->getConfig('cartMaxItem');
$itemMaxQuantity = rex_addon::get('mf_cart')->getConfig('itemMaxQuantity');
$useCookie = (rex_addon::get('mf_cart')->getConfig('useCookie') == 'true' ? true : false);
$cart = new Cart([
'cartMaxItem' => $cartMaxItem,
'itemMaxQuantity' => $itemMaxQuantity,
'useCookie' => $useCookie,
]);
$cart = new Cart([
'cartMaxItem' => 0,
'itemMaxQuantity' => 0,
'useCookie' => false,
]);
| Parameter | Type | Description |
|---|---|---|
| cartMaxItem | int | Die maximale Anzahl an Items, die im Warenkorb liegen können. 0 = Unbegrenzt |
| itemMaxQuantity | int | Maximale Anzahl eines Items, das in den Warenkorb gelegt werden kann. 0 = Unbegrenzt |
| useCookie | bool | Ohne Cookie wird der WK nur in der Session gespeichert. Wenn der Browser geschlossen wird, wird der WK geleert. Mit gesetztem Cookie bleibt der Warenkorb bei folgenden Besuchen innerhalb der nächsten 7 Tage bestehen. |
