When creating a custom field to collect the user’s phone number or zip code, you may want to add validation to the field. This prevents users from entering a value using invalid characters or the wrong length. To set up validation on your custom fields, follow these steps.
First, head to the Custom JS Apps section of your account.
On the next page, click Install for the validation you want to use.
Each app will ask you to provide some information.
Fill in the fields appropriately and click Install.
If you want the validation to apply to the same field on all your boxes, you’re done!
If you only want this to apply to certain boxes in your account, head to Custom JS Boxes and use the includes or excludes field to assign specific boxes to the code.
If you have any questions, send us an email, and we’ll be happy to help.
