Check the Number of Purchases a User Has Ever Made

Use Case: You need to check the amount of purchases a user has ever made. If it’s more than 10, display a “thank you” message at the top of the template.


{if length(profile.purchases) > 10}
Thank you for being a loyal customer! Take $15 off your next purchase.

Explanation: This scripts uses the length() function to check the number of purchases a user has ever made by referencing the “profile” object, specifically, the “purchases” array, which is an array of all user purchases. It is then wrapped in a conditional “if” statement that says to show a discount offer if the length of purchases is greater than 10, i.e. the user has purchased more than ten times.
