Migrating a discounted cart subtotal script
Two scripts can look identical here and mean opposite things. One measures what its own earlier lines left behind; the other measures what somebody else’s discount left behind, and only the second is out of anyone’s hands.
Shopify-beperkingIt subtracted the shopper’s discount code from the subtotal first, then compared what was left against its threshold.
Plak het in Scripts-redding en kijk wat eruit komt
- Kopieer de Ruby met de knop naast elk Script op deze pagina.
- Open in je Shopify-beheer Stackable, dan Hulpmiddelen, dan Scripts-redding.
- Plak het daar, lees wat het hulpmiddel zegt te gaan bouwen en vergelijk dat met de instellingen op deze pagina.
Scripts-redding zit in het Pro-abonnement. Er wordt niets gepubliceerd totdat je vertelt wat je oude Script gaf en beide bedragen tot op de cent kloppen.

Output.cart = Input.cartShopify cannot do this at checkout
Your Script measured its threshold against a subtotal that another discount had already reduced. Discounts at checkout all run at the same moment and cannot see each other's work, so we only ever see the original amounts.
Dit is een beperking in Shopify en geen gat in Stackable. Geen enkele kortings-app kan dit vandaag herbouwen, en daarom gaat de link hieronder naar de documentatie van Shopify zelf en niet naar de onze.

Er is hier geen winkelwagen om te testen, want er wordt niets gebouwd. Dit plakken levert de melding hierboven op en verder geen campagne.
