Skriptexempel för poster

Skripts för poster påverkar artiklar i en varukorg och kan ändra egenskaper och pris. Skripten körs varje gång som en varukorgs attribut ändras, som tillägg eller borttagande av en artikel, ändrad leveransadress eller tillägg av en rabattkod.

Skapa ett nytt skript med en tom mall, för att använda mallar på sidan.

Steg:

  1. Från din Shopify-administratör går du till appar > Script Editor.
  2. Klicka på skapa skript.
  3. Klicka på Poster.
  4. Välj tom mall, klicka sedan skapa skript.
  5. I avsnittet för Ruby-källkod, radera standardraden för kod: Output.cart = Input.cart
  6. Kopiera ett skript från sidan och klistra in det i avsnittet för Ruby-källkod.
  7. Redigera skriptets avsnitt för anpassningsbara inställningar för att få det att fungera i din butik.
  8. Testa ditt skript. Om du vill ha mer information, se Testa och felsök Shopify-skript.
  9. Efter att ha testat:
    • klicka på spara utkast för att spara ett opublicerat utkast av skriptet, eller
    • klicka på spara och publicera för att skapa och publicera skriptet.

Differentierad varukorgsrabatt efter spenderat belopp

Använd detta skript för att erbjuda en rabatt med ett dollarbelopp som ökar i förhållande till det totala värdet på artiklarna i varukorgen. Denna rabatt fördelas så jämnt som möjligt på de enskilda artiklarna i varukorgen.

Till exempel, erbjud kunder 25 USD i rabatt på summan om de handlar för över 150 USD, 50 USD i rabatt om de handlar för över 300 USD eller 75 USD i rabatt om de handlar för över 400 USD.
