Field Validators

Field validators are used to enable validation of field values entered by users against your own datasets.

Field validators allow you to configure custom validation in a form where input entered by users for that form is validated against your own datasets.

Field validators require you to have an existing dataset to validate values against.

To create a field validator:

• Go to the form builder and click on the settings icon for the field you want to edit.

• Click on the validation settings tab.

• Click on the "Add Custom Validator" button

• The Custom Field Validator form appears

• Provide a name for the validator

• Create or select a dataset connection

• Choose a lookup column for the validator. The lookup column is the field in the dataset that the form field value will be compared against.

• Provide a custom error message to be displayed to the user when the validation fails.

• Click on the save button.

• You can add as many validators as you require. This ensures you can validate that a user provided value on the form is present in multiple datasets.
