Hello, I’m trying to migrate javascript scripts to Shopify extensions, I don’t know how to add additional validation to address field 1 on the contact info page in the checkout. Can you tell me how or where to find a solution?
You could try Ultimate Checkout Rules. You can add all kinds of validations and other checkout rules for your checkout using the AI assistant.
Hi @maxdanko
Step 1: Ask ChatGPT, Generate a RegEX to validate “[write your purpose]” string
Step 2: Install Checkout Boost and go to Checkout Validations screen
Step 3: Go to “Address string validation”
Step 4: Add generated RegEx, or explore more
Step 5: Test and launch.
Hope that helps!
