Script di voci di esempio

Gli script delle voci influiscono sugli articoli presenti nel carrello e possono modificarne proprietà e prezzi. Questi script vengono eseguiti a ogni modifica di attributi del carrello, come ad esempio l'aggiunta o la rimozione di un articolo, la modifica dell'indirizzo di spedizione o l'aggiunta di un codice sconto.

Per utilizzare i template su questa pagina, crea un nuovo script con un template vuoto.

Procedura:

  1. Dal pannello di controllo Shopify vai su App > Script Editor.
  2. Clicca su Crea script.
  3. Clicca su Voci.
  4. Seleziona Template vuoto e clicca su Crea script.
  5. Nella sezione Codice sorgente di Ruby, elimina la riga di codice predefinita: Output.cart = Input.cart
  6. Copia uno script da questa pagina e incollalo nella sezione Codice sorgente di Ruby.
  7. Modifica la sezione Impostazioni personalizzabili dello script affinché funzioni nel negozio.
  8. Testa lo script. Per maggiori informazioni, consulta Testare ed eseguire il debug degli script Shopify.
  9. Dopo il test: - Clicca su Salva bozza per salvare una bozza non pubblicata dello script oppure
    • Clicca su Salva e pubblica per creare e pubblicare lo script.

Sconto incrementale sul carrello basato sulla spesa

Utilizza questo script per offrire uno sconto di importo che aumenta in base al valore totale degli articoli nel carrello. Questo sconto è distribuito nel modo più uniforme possibile tra i singoli articoli nel carrello.

Ad esempio, puoi utilizzare questo script per offrire ai clienti 25 $ di sconto sul totale se spendono più di 150 $, 50 $ di sconto se spendono più di 300 $ o 75 $ se spendono più di 400 $.

Limita le quantità di prodotti

Usa questo script per applicare limiti alla quantità di prodotti specifici.

Ad esempio, puoi usare lo script per impedire ai clienti di acquistare più di 1 "Prodotto X" in un unico ordine.

# ================================ Customizable Settings ================================
# ================================================================
# Product Quantity Limits
#
# If the quantity of any "matching" items is greater than the
# entered threshold, the excess items are removed from the cart.
# It should be noted that there will be no notice to the customer
# when this happens.
#
# - 'enable' determines whether the campaign will run. Can be:
# - 'true' to run
# - 'false' to not run
# - 'product_selector_match_type' determines whether we look for
# products that do or don't match the entered selectors. Can
# be:
# - ':include' to check if the product does match
# - ':exclude' to make sure the product doesn't match
# - 'product_selector_type' determines how eligible products
# will be identified. Can be either:
# - ':tag' to find products by tag
# - ':type' to find products by type
# - ':vendor' to find products by vendor
# - ':product_id' to find products by ID
# - ':variant_id' to find products by variant ID
# - ':all' for all products
# - 'product_selectors' is a list of identifiers (from above)
# for qualifying products. Product/Variant ID lists should
# only contain numbers (ie. no quotes). If ':all' is used,
# this can also be 'nil'.
# - 'variant_level_limit' determines whether the below limit
# is applied on a variant, or a total quantity, level. For
# example, can I have X number of individual "matching" items,
# or can I only have X number total of "matching" items.
# Can be:
# - 'true' to limit at a variant level
# - 'false' to limit total quantity
# - 'quantity_allowed' is the number of products allowed
