Validation groups

Define validation rules for groups of fields

The Validation groups node allows you to define custom validation rules for groups of fields.

Validation group can then be selected on a Shopping Cart app, and when the customer attempts to proceed to the Checkout-step of the checkout flow, the values of fields with validation are tested against the validation rules - if a field does not validate you return to the previous step.

To create a validation group:

1. Click New validation group
2. Provide a name and check *Disable validation if all fields are empty if relevant (typically for debugging)
3. Save

Validation groups consist of a set of fields, and for each field some validation rules such as 'must contain @' or 'Required'. To add a field to the validation group:

1. Click Manage fields
2. Click Add new validation
3. Select a Field for validation rules
4. Decide on a validation Rule policy for this field:
   • All rules must validate
   • At least one rule must validate
5. Click Save

For each field you can then add validation rules as necessary, when clicking the specific field on the list:

1. Click Manage rules
2. Click Add new rule
3. Select an Operator (e.g. Contains) and optionally a parameter (e.g. @)
4. Click Save

The following operators are available:

Operator	Description
Required	Checks that the field is not empty
Contains/Does not contain	Checks for the presence/absence of a specific value
Equals/Does not equal	Checks the field for an exact value (and either approves or rejects it)
Is integer/Is numeric	Checks that the field contains an integer (whole numbers) or is numeric (whole numbers and decimals)
Minimum length/Maximum length	Checks the minimum or maximum length of a field value (in characters)
Is less/greater than	Checks against a minimum or maximum value. Works for both numbers and alphanumeric characters
Is valid email	Checks if the value is a valid email address
Is valid/Is not expired/Is currency proper (Gift card)	Checks if the value is a valid, a not expired gift card or the correct currency
Is valid/Is not expired (Voucher)	Checks if the value is a valid or a not expired voucher
Regular expression	Allows you to enter a regular expression and check the field value against that. This allows you to check for a variety of formats, e.g. postal codes, phone numbers, and so forth. For more details in regular expressions, please see .NET’s rules for regular expressions.
